Too Many Whales?

sunshine hours

Whales recovering. Thats good. Right? Not according to “experts”.

This is good … right?

Rapid growth in humpback whales in the Australian Southern Ocean could lead to a ‘population explosion’

And this is good too … right?

The population was brought to the brink of extinction in the 1960s, with just a few hundred surviving in the wild, a result of commercial whaling.

However, conservation efforts and the introduction of the Endangered Species Act saw the humpback population almost totally recover by 2015, to more than 25,000.

But nooo. Climate change rears its ugly head!

experts are now warning that the population could become too large for the ecosystem to support because of declining food sources in our oceans due to climate change.

What declining food sources? The population of whales just went up by 100x!!!

Climate change is such a party pooper.

If they stopped shooting 600 polar…

A Critical Framework For Climate Change

Science Matters

This dialogue framework was proposed for a debate between William Happer and David Karoly sponsored by The Best Schools.  As you can see it reads like an high hurdle course for alarmists/activists.  There are significant objections at every leap in connecting the beliefs.

Happer’s Statement: CO₂ will be a major benefit to the Earth

Earth does better with more CO2.  CO2 levels are increasing

Atmospheric transmission of radiation: Tyndall correctly recognized in 1861 that the most important greenhouse gas of the Earth’s atmosphere is water vapor. CO2 was a modest supporting actor, then as now.

Radiative cooling of the Earth: Clouds are one of the most potent factors controlling Earth’ s surface temperature.

The Schwarzschild equation:  The observed intensity I of upwelling radiation comes from the radiation emitted by the surface and by greenhouse gases in the atmosphere above the surface. The rate of change of the intensity with altitude…

Cold outbreaks are not caused by global warming

Reblogged from Watts Up With That:

Global cooling – and global totalitarian socialism – are the catastrophes we should fear most

Dr. Jay Lehr and Tom Harris

What do heat waves, floods, droughts, rising sea levels, forest fires, hurricanes, African wars, mass extinctions, disease outbreaks, and human and animal migrations from South America and the Middle East have in common?

According to climate activists, they are all caused by dangerous man-made global warming. And this, in turn, is supposedly caused by rising carbon dioxide (CO2) levels resulting from our use of fossil fuels.

They might as well add alien invasions to the list, because it is all nonsense. Indeed, the climate scare industry has achieved such a level of absurdity that, on February 1, journalist Andrew Revkin reported in a National Geographic article that, “Many stories in recent days highlighted studies concluding that global warming is boosting the odds of cold [weather] outbreaks.”

(As we delve into the realm of absurdity, however, let us not forget that, in 2011, scientists from NASA’s Planetary Science Division and Michael Mann’s Penn State University actually presented a report speculating that extraterrestrial environmentalists could be so appalled by our planet-polluting, climate-changing ways that they could view humans as a threat to the entire intergalactic ecosystem and decide to destroy humanity!)

Among the most absurd of recent climate alarm statements is the one attributing recent cold spells to manmade global warming came from University of Michigan professor emeritus of environment and sustainability Donald Scavia, who said: “In the past there was a very strong gradient of cold air at the poles and warmer air south of the poles. That gradient kept the cold where it is…. As the poles are warming faster than the rest of the planet, that gradient weakens, allowing the cold air currents to dip south.”

Dr. Tim Ball, an environmental consultant and former climatology professor at the University of Winnipeg in Manitoba, said that Scavia’s statement “is utter rubbish.” Ball explained, “It’s wrong in every aspect, from the basic assumption to the interpretation. In fact, a gradient makes things move. It doesn’t ‘keep the cold where it is.’”

It’s also a mistake to think that, if human-produced CO2 is actually causing global warming, the poles will warm first. “There is no evidence of that; they just are assuming it to be the case,” Dr. Ball emphasized.

And, if the poles did warm first, Ball explained, the reduced temperature difference between the poles and lower latitude regions would reduce extreme weather events, not intensify them, as climate campaigners claim. After all, weather and extreme weather events are driven by the temperature gradient between latitudes. A warming Arctic would result in less intense cold outbreaks and a lesser intrusion of cold artic air colliding with warm moist air in warmer regions. Climate alarmists have their science backwards.

Ball noted that the real cause of the severe cold outbreaks in the United States is a wavy Jet Stream.

The Jet Stream is a thin band of strong winds that flow rapidly around the planet from west to east at approximately 10 km altitude. The Jet Stream divides warm air masses, typically found at low latitudes towards the tropics, from cold air masses, usually found at high latitudes near the poles.

However, a very wavy jet stream, as we are experiencing now (and have many times in the past), allows frigid Arctic air to move south to normally warmer latitudes and warm tropical air to push into Polar latitudes. The result is an increase in extreme weather events, including the cold outbreaks in the USA. It has nothing to do with global warming. In fact, the most common cause of a wavy Jet Stream is global cooling. History shows that severe weather increases with a cooling world, not a warming one.

As to fears of more cold outbreaks due to global warming, Ball laughed, “They’re making it all up!”

Clearly, there is no end to the deceptions that the climate lobby will tell the public in order to deprive the world of reliable, inexpensive fossil fuel-based energy, the foundation of modern living standards. Perhaps the greatest deception of all is what real scientists call cherry picking – highlighting data that advance their theory and agenda, while ignoring data that do not support their politics.

The graph below explains how they do it. The overall trend of the data is obvious: as variable “A” declines, variable “B” increases. But if you choose only a small portion of the data (or just a few years out of 100 or 1,000), you can declare the trend to be anything you want – including having “A” stay the same as “B” increases, and even having “A” increase as “B” increases.


This is the sleight-of-hand used by global warming alarmists who want the public to believe that burning fossil fuels and increasing the atmosphere’s carbon dioxide must be stopped at all costs. They want to run the nation and the world on expensive, inconvenient, unreliable wind and solar energy. They ignore the fact that those energy must be totally backed up by dependable energy sources like fossil fuel or nuclear in order to stop the grid from collapsing. It has been calculated that, were the Midwest to be dependent only on wind and solar power, at least one million people would have died of hypothermia during the recent minus-50 degrees F cold spell.

As demonstrated by Climate Change Reconsidered II: Fossil Fuels, the latest report of the Nongovernmental International Panel on Climate Change, the impact of fossil fuels (coal, oil and natural gas) has been overwhelmingly positive. The report’s Summary for Policymakers states:

“Fossil fuels have benefited humanity by making possible the prosperity that occurred since the first Industrial Revolution…. Fossil fuels also power the technologies that reduce the environmental impact of a growing human population, saving space for wildlife…. Nearly all the impacts of fossil fuel use on human well-being are net positive (benefits minus costs), near zero (no net benefit or cost), or are simply unknown.”

Besides raising living standards across the world, fossil fuel use has helped elevate CO2 in our atmosphere from a level dangerously close to the point at which plants start to die – to where we are today, with the Earth once again “greening,” as crops, forests and grasslands grow faster and better.

The global warming scare has never been about science, or even climate for that matter. The long-term goal of many activists is to unite the world under a single socialistic government in which there is no capitalism, no democracy and no freedom. After all, personal freedom is fueled largely by access to affordable energy.

An intermediate goal of climate alarmism is thus to limit the amount of energy that is available and place it under tight government control. Inexpensive fossil fuels remain an obstacle to their vision, and so must be done away with entirely, climate campaigners maintain. We must not let them succeed.

Human Activity in China and India Dominates the Greening of Earth, NASA Study Shows

From NASA Ames:
BLUF: “Once people realize there’s a problem, they tend to fix it…In the 70s and 80s in India and China, the situation around vegetation loss wasn’t good; in the 90s, people realized it; and today things have improved. Humans are incredibly resilient. That’s what we see in the satellite data.” –Rama Nemani, NASA’s Ames Research Center

Human Activity in China and India Dominates the Greening of Earth, NASA Study Shows

Feb. 11, 2019
A map showing increases in leaf area per year, represented in green. India and China stand out with large areas of dark green.
Over the last two decades, the Earth has seen an increase in foliage around the planet, measured in average leaf area per year on plants and trees. Data from NASA satellites shows that China and India are leading the increase in greening on land. The effect stems mainly from ambitious tree planting programs in China and intensive agriculture in both countries.

The world is literally a greener place than it was 20 years ago, and data from NASA satellites has revealed a counterintuitive source for much of this new foliage: China and India. A new study shows that the two emerging countries with the world’s biggest populations are leading the increase in greening on land. The effect stems mainly from ambitious tree planting programs in China and intensive agriculture in both countries.

The greening phenomenon was first detected using satellite data in the mid-1990s by Ranga Myneni of Boston University and colleagues, but they did not know whether human activity was one of its chief, direct causes. This new insight was made possible by a nearly 20-year-long data record from a NASA instrument orbiting the Earth on two satellites. It’s called the Moderate Resolution Imaging Spectroradiometer, or MODIS, and its high-resolution data provides very accurate information, helping researchers work out details of what’s happening with Earth’s vegetation, down to the level of 500 meters, or about 1,600 feet, on the ground.

Taken all together, the greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year, compared to the early 2000s – a 5% increase.

“China and India account for one-third of the greening, but contain only 9% of the planet’s land area covered in vegetation – a surprising finding, considering the general notion of land degradation in populous countries from overexploitation,” said Chi Chen of the Department of Earth and Environment at Boston University, in Massachusetts, and lead author of the study.

An advantage of the MODIS satellite sensor is the intensive coverage it provides, both in space and time: MODIS has captured as many as four shots of every place on Earth, every day for the last 20 years.

“This long-term data lets us dig deeper,” said Rama Nemani, a research scientist at NASA’s Ames Research Center, in California’s Silicon Valley, and a co-author of the new work. “When the greening of the Earth was first observed, we thought it was due to a warmer, wetter climate and fertilization from the added carbon dioxide in the atmosphere, leading to more leaf growth in northern forests, for instance. Now, with the MODIS data that lets us understand the phenomenon at really small scales, we see that humans are also contributing.”

China’s outsized contribution to the global greening trend comes in large part (42%) from programs to conserve and expand forests. These were developed in an effort to reduce the effects of soil erosion, air pollution and climate change. Another 32% there – and 82% of the greening seen in India – comes from intensive cultivation of food crops.

Land area used to grow crops is comparable in China and India – more than 770,000 square miles – and has not changed much since the early 2000s. Yet these regions have greatly increased both their annual total green leaf area and their food production. This was achieved through multiple cropping practices, where a field is replanted to produce another harvest several times a year. Production of grains, vegetables, fruits and more have increased by about 35-40% since 2000 to feed their large populations.

How the greening trend may change in the future depends on numerous factors, both on a global scale and the local human level. For example, increased food production in India is facilitated by groundwater irrigation. If the groundwater is depleted, this trend may change.

“But, now that we know direct human influence is a key driver of the greening Earth, we need to factor this into our climate models,” Nemani said. “This will help scientists make better predictions about the behavior of different Earth systems, which will help countries make better decisions about how and when to take action.”

The researchers point out that the gain in greenness seen around the world and dominated by India and China does not offset the damage from loss of natural vegetation in tropical regions, such as Brazil and Indonesia. The consequences for sustainability and biodiversity in those ecosystems remain.

Overall, Nemani sees a positive message in the new findings. “Once people realize there’s a problem, they tend to fix it,” he said. “In the 70s and 80s in India and China, the situation around vegetation loss wasn’t good; in the 90s, people realized it; and today things have improved. Humans are incredibly resilient. That’s what we see in the satellite data.”

This research was published online, Feb. 11, 2019, in the journal Nature Sustainability.

CO2 and crops: NAS vs. science

Reblogged from Watts Up With That:

WUWT regular David Burton writes:

One of the most pernicious examples of disinformation promoted by the Climate Industry is the claim that manmade climate change from CO2 emissions threatens agriculture and “food security.” That’s the exact opposite of the truth. CO2 is “plant fertilizer,” and hundreds of agricultural studies have shown that higher CO2 levels are dramatically beneficial for agriculture, to levels far above what we can ever hope for outdoors.

Most plants grow best with daytime atmospheric CO2 of at least about 1500 ppmv. That’s about what CO2 levels are thought to have averaged during the Cretaceous. It’s 1090 ppmv higher than the current average outdoor level of about 410 ppmv.

In other words, most plants would grow best if CO2 levels were increased by more than eight times the measly 130 ppmv by which mankind has managed to increase CO2 levels since the “pre-industrial” Little Ice Age. (Levels even higher than that wouldn’t hurt plants, but they wouldn’t help much, either.)
(click to enlarge)

That’s why most commercial greenhouses use “CO2 generators” to raise daytime CO2 to about that level. It makes the plants healthier, faster-growing, and more productive.

Note: There are several different kinds of photosynthesis. Plants that use “C3” or “CAM” photosynthesis benefit the most from higher CO2 levels. “C4” crops benefit the least, but even C4 crops benefit when under drought stress. Most crops use C3 photosynthesis. There are only four important C4 crops, all of them grasses: corn [maize], sugarcane, sorghum, and millet.)
(dependence of the rate of photosynthesis on the amount of CO2 in the air in C3 and C4 plants, from; click to enlarge)

The value of higher CO2 levels for agriculture is not a new discovery. Svante Arrhenius wrote about it in 1908, and cited a source from as early as 1872. Arrhenius predicted that:

“By the influence of the increasing percentage of carbonic acid [CO2] in the atmosphere, we may hope to enjoy ages with more equable and better climates, especially as regards the colder regions of the earth, ages when the earth will bring forth much more abundant crops than at present, for the benefit of rapidly propagating mankind.”

In 1920, Scientific American reported the results of German greenhouse and F.A.C.E. experiments with CO2 supplementation. The experiments were so spectacularly successful that SciAm called anthropogenic CO2 the precious air fertilizer.” From this photo, which accompanied the article, you can certainly see why:

SciAm 1920: Carbonic Acid Gas to Fertilize the Air
(click to view article)

Over the last century, many hundreds of studies have measured the large benefits of higher CO2 levels for most crops:
(Dr. Sherwood Idso showing the effect of CO2 level on pine trees; click to enlarge)

But the National Academy of Sciences would have you believe that global warming threatens agricultural productivity. So let’s examine that claim.

Here’s a recent article from the Farm Bureau, reporting preliminary U.S. state-by-state corn and soybean yield numbers for 2018:

Farm Bureau 2018: Corn and Soybean Yields are YUUUGE
(click to view article)

Of course the headline obviously suggests that climate change hasn’t hurt corn and soybean production, so far. But that’s not the most interesting part of it.

Look at the wide distribution of states, which grow corn. In this map, from the article, you can see that Minnesota’s 2018 corn yields averaged 191 Bushels Per Acre (BPA), and Mississippi’s corn yields averaged 185 BPA. The “breadbasket” states of Illinois and Iowa both had even bigger bumper crops, with yields above 200 BPA:

Now, compare that map with this growing-zone map (courtesy of In it you can see that Minnesota and Mississippi are about four climate/growing zones apart. Minnesota is mostly zone 4, and Mississippi is almost entirely zone 8. Illinois and Iowa are a mix of zones 5 & 6:

U.S. climate zones span 10°F, so the center-to-center difference between four zone numbers is 40°F = 22.2 °C.

However, in this map you can see that Minnesota’s corn is mostly from the southern half of the state, which is a mix of zone 4 and zone 5, and Mississippi’s corn is mostly from the northwest half of the state, which is upper zone 8.

So the average temperature difference between the middle of the prime corn-growing regions of the two states is a bit less than 40°F, I’d call it about 33 ±2°F.

In Celsius, that’s a temperature difference of 17.2 to 19.4 °C (midpoint 18.3°C), between Mississippi (185 BPA) and Minnesota (191 BPA).

In other words, it is plain that an average temperature difference of about 18°C has little effect on corn yields.

Many other major crops are even less climate-sensitive:

● Wheat is profitably grown in zones 3 through 9, from Saskatchewan to south Texas, a temperature range of over 35°C:


● Maine & Florida are both major producers of Potatoes:

● Soybeans are grown from Louisiana & Mississippi to Minnesota & Canada:

What, then, are we to make of this PNAS paper?

Zhao C, et al. (2017) Temperature increase reduces global yields of major crops in four independent estimates. Proc Natl Acad Sci USA 114:9326–9331. doi:10.1073/pnas.1701762114

From the title you would probably assume that they found anthropogenic climate change causes crop yields to decline, because negative impacts of temperature increases exceed the positive impacts of CO2 fertilization and improved drought resistance from higher CO2 levels. That’s what you’re supposed to think, and that’s how the press release reported it:

Climate change will cut crop yields,” said the caption on, and called the little five-page paper “a major scientific report.”

Global Warming Will Sear Three of Four Major Grain Crops,” said the caption on Haaratz.

But if you read the paper, or if you read Eric Worrall’s excellent 2017 analysis of it on WUWT, you’ll discover that the authors did not actually say that. Instead, they wrote that they were discussing what they think would happen to yields in an imaginary world “without CO2 fertilization, effective adaptation, and genetic improvement.”

Of course “without CO2 fertilization” means they’re ignoring the beneficial effects of higher CO2 levels, which obviously divorces the paper from any pretense of presenting predictions of future reality.

But it’s even worse than that. Can you guess what their assumption of no “effective adaptation” to a warming climate actually means?

For annual crops, “effective adaptation” means adjusting spring planting dates, and perhaps adjusting cultivar selection. That’s all.

It’s not rocket science. In America’s heartland, moving the planting date up by about six days compensates for 1°C of warming:

So +4°C of warming is equivalent to planting about 24 days late.

The assumption of no “effective adaptation” to warming means these 29(!) authors assumed farmers are all idiots, who can’t figure out when they should plant their crops. (Projection, maybe?)

It’s utterly preposterous. The reality is that most farmers are not idiots, anthropogenic CO2 is highly beneficial “air fertilizer,” and the further that CO2 levels rise, the more productive farms will become.

That fact is true for the great majority of crops, nearly everywhere in the world. Yet the NAS has been promoting the anti-scientific claim that rising CO2 levels are bad for agriculture, for years. This 2011 NAS / NRC propaganda graph is a particularly outrageous example:
(click to enlarge)

Notice the red “US Maize” and purple “India Wheat” traces, and where they intersect the 4°C line. You can see that they’re predicting that in the event of a 4°C temperature increase, U.S. maize (corn) yields would decline by a devastating 60%, and wheat yields in India would fall 68%.

(Of course such a large temperature increase is thoroughly implausible, but never mind that. That’s a different rant, for a different day.)

Today’s rant is this:  That NAS / NRC graph is a lie.

If a mere 4°C of warming were actually that destructive to corn yields, it would obviously be impossible to profitably grow corn even in Tennessee & Kentucky (zone 7, 174-175 BPA in 2018), let alone Mississippi (zone 8, 185 BPA).

Likewise, if a mere 4°C temperature increase were actually that destructive to wheat yields, then it would obviously be impossible for North Americans to cultivate wheat across seven climate zones, from Saskatchewan to south Texas, spanning an average temperature range of about 35°C.

That NAS / NRC graph is utter nonsense. But even though it is old, it’s still being used by climate change zealots to mislead people. I stumbled across it because someone posted it in the comments on an article at ArsTechnica. (I’m currently banned for a week there, for “ignoring moderation,” because I disagreed with their leftist moderator. My first comment there [screenshot] has been deleted, too, but some of the others are still there. They look “faded” because the ArsTechnica comment system fades-out comments with lots of downvotes.)

On March 22, 2012, Rud Istvan did a wonderful, in-depth demolition of that graph, on WUWT & ClimateEtc:

Yet, despite their propaganda graph having been completely debunked, the NAS is still disseminating it, to promote the climate scare.

Here it is on their web site, on p.28 of a little 40 page propaganda booklet, which appears to be designed to be used as a resource by schoolteachers:

Here it is, in convenient PowerPoint format, for incorporation into your talk at the local garden club (slide 21):

(The file metadata indicates that the slides were created by “Rebecca” in June, 2013 — more than a year after Rud had discredited the graph.)

It’s also on p.161 of this free 299-page ebook:

If Zhao and his 28 co-authors really believe, as they claimed in their PNAS paper, that correctly assessing the impact of climate change on agriculture is “critical to maintaining global food supply,” then it is incredibly cynical of them and the NAS to publish misleading papers and graphs which encourage policymakers to take steps that will actually reduce that the global food supply.

I’m beginning to wonder: Does the “A” in “NAS” is still stand for “Academy of,” or does it now stand for “Anti-,”?

CO2 Not So Much, 60 Year Cycle Paper Actually Got Published

Reblogged from Musings from the Chiefio:

The article is cited in a couple of other places. I ran into it here:

Where Tallbloke points to the Elsevier / Science Direct origin (where it is paywalled…)

This supports the idea that temperature cycles in the region of 60 years are very likely a common feature of Earth’s climate.

Deploying a new technique for the first time in the region, geoscientists at the University of Massachusetts Amherst have reconstructed the longest and highest-resolution climate record for the Northeastern United States, which reveals previously undetected past temperature cycles and extends the record 900 years into the past, well beyond the previous early date of 1850, reports

And points at the description of the article at

As Miller explains, they used a relatively new quantitative method based on the presence of chemical compounds known as branched glycerol dialkyl glycerol tetra ethers (branched GDGTs) found in lakes, soils, rivers and peat bogs around the world. The compounds can provide an independent terrestrial paleo-thermometer that accurately assesses past temperature variability.

Miller says, “This is the first effort using these compounds to reconstruct temperature in the Northeast, and the first one at this resolution.” He and colleagues were able to collect a total of 136 samples spanning the 900-year time span, many more than would be available with more traditional methods and from other locations that typically yield just one sample per 30-100 years.

I make that about a 6 2/3 year long duration per sample. So 9 samples per 60+ year cycle. A bit coarse but it ought to resolve with 4 to 5 samples per arc of excursion.

I find it a bit amusing that they are all worked up about having rediscovered the Medieval Warm Period and the Little Ice Age; but OK, at least we’re finally getting back to reality. They are amazed at the “new” finding of the same 60ish year cycle that has been found just about everywhere anyone actually looks for it. OK… All bolding by me.

In their results, Miller says, “We see essentially cooling throughout most of the record until the 1900s, which matches other paleo-records for North America. We see the Medieval Warm Period in the early part and the Little Ice Age in the 1800s.” An unexpected observation was 10, 50-to-60-year temperature cycles not seen before in records from Northeast U.S., he adds, “a new finding and surprising. We’re trying to figure out what causes that. It may be caused by changes in the North Atlantic Oscillation or some other atmospheric patterns. We’ll be looking further into it.”

He adds, “We’re very excited about this. I think it’s a great story of how grad students who come up with a promising idea, if they have enough support from their advisors, can produce a study with really eye-opening results.” Details appear in a recent issue of the European Geophysical Union’s open-access online journal, Climate of the Past.

The authors point out that paleo-temperature reconstructions are essential for distinguishing human-made climate change from natural variability, but historical temperature records are not long enough to capture pre-human-impact variability. Further, using conventional pollen- and land-based sediment samples as climate proxies can reflect confounding parameters rather than temperature, such as precipitation, humidity, evapo-transpiration and vegetation changes.

Or put more succinctly, our thermometer record is short and lousy and our proxy record is pretty damn poor too.

Then TallBloke also points at a couple of other links. Here’s the paywall:

Anthropogenic CO2 warming challenged by 60-year cycle

Author François Gervais


Time series of sea-level rise are fitted by a sinusoid of period ~ 60 years, confirming the cycle reported for the global mean temperature of the earth. This cycle appears in phase with the Atlantic Multidecadal Oscillation (AMO). The last maximum of the sinusoid coincides with the temperature plateau observed since the end of the 20th century. The onset of declining phase of AMO, the recent excess of the global sea ice area anomaly and the negative slope of global mean temperature measured by satellite from 2002 to 2015, all these indicators sign for the onset of the declining phase of the 60-year cycle. Once this cycle is subtracted from observations, the transient climate response is revised downwards consistent with latest observations, with latest evaluations based on atmospheric infrared absorption and with a general tendency of published climate sensitivity. The enhancement of the amplitude of the CO2 seasonal oscillations which is found up to 71% faster than the atmospheric CO2 increase, focus on earth greening and benefit for crops yields of the supplementary photosynthesis, further minimizing the consequences of the tiny anthropogenic contribution to warming.

A nice summary of other 60 year-ish cycle evidence in this link also from TallBloke:

So what are these “branched glycerol dialkyl glycerol tetraethers”?
Found that answer here:

From their Figure 2:



Strange things made in the membrane of various microbes in the water column that change with the temperature.

From the actual paper intro:

A cycle of period ~60 years has been reported in global mean temperature of the earth (Schlesinger and Ramankutty, 1994; Ogurtsov et al., 2002; Klyashtorin and Lyubushin, 2003; Loehle, 2004; Zhen-Shan and Xian, 2007; Carvalo et al., 2007; Swanson and Tsonis, 2009; Scafetta, 2009; Akasofu, 2010; D’Aleo and Easterbrook, 2010; Loehle and Scafetta, 2011; Humlum et al., 2011; Chambers et al., 2012; Lüdecke et al., 2013; Courtillot et al., 2013; Akasofu, 2013; Macias et al., 2014; Ogurtsov et al., 2015). This cycle and others of smaller amplitude were found to be correlated with the velocity of the motion of
the sun with respect to the center of mass of the solar system (Scafetta, 2009). This cycle is also in phase with AMO index (Knudsen et al., 2011; McCarthy et al., 2015).
Section 2 will search for additional signatures of this 60-year cycle in major components and sensitive indicators of climate. The impact on climate of the CO2 emitted by burning of fossil fuels is a long-standing debate illustrated by 1637 papers found in the Web of Science by crossing the keywords

[anthropogenic] AND [greenhouse OR CO2] AND [warming]

This is to be compared to more than 1350 peer-reviewed papers which express reservations about dangerous anthropogenic CO2 warming and/or insist on the natural variability of climate (Andrew,2014). The transient climate response (TCR) is defined as the change in global mean surface temperature at the time of doubling of atmospheric CO2 concentration. The range of uncertainty reported by AR5 (2013) is very wide, 1–2.5 °C. More recent evaluations, later than the publication of AR5 (2013), focus on low values lying between 0.6 °Cand 1.4 °C (Harde, 2014; Lewis and Curry, 2014; Skeie et al., 2014; Lewis, 2015). The infrared absorption of CO2 is well documented since the availability of wide-band infrared spectrometry (Ångström, 1900).

OMG! Actually talking about solar motion and AMO connections! Next thing you know they will discover the lunar cycle involvement and how tides are directly shifting the ocean and air flows as part of those celestial motions…

The intro then goes into a discussion of the IR spectra and transmission where it finds the approved models lacking and also finds that yes, Virginia, we have had a pause in temperature rises…

The controversy has reached a novel phase because, contrary to CMIP3 and CMIP5 warming projections (AR5, 2013), global mean temperatures at the surface of the earth display a puzzling « plateau » or « pause » or « hiatus » since the end of the last century (McKitrick, 2014). This hiatus seems to have encouraged climate modelers to refrain from exaggerated warming projections.

The paper is full of many such goodies. It goes on to find a large 60 year cycle effect and a very muted CO2 effect.

Skipping down to the summary:

Dangerous anthropogenic warming is questioned (i) upon recognition of the large amplitude of the natural 60–year cyclic component and (ii) upon revision downwards of the transient climate response consistent with latest tendencies shown in Fig. 1, here found to be at most 0.6 °C once the natural component has been removed, consistent with latest infrared studies (Harde, 2014). Anthropogenic warming well below the potentially dangerous range were reported in older and recent studies (Idso, 1998; Miskolczi, 2007; Paltridge et al., 2009; Gerlich and Tscheuschner, 2009; Lindzen and Choi, 2009, 2011; Spencer and Braswell, 2010; Clark, 2010; Kramm and Dlugi, 2011; Lewis and Curry, 2014; Skeie et al., 2014; Lewis, 2015; Volokin and ReLlez, 2015). On inspection of a risk of anthropogenic warming thus toned down, a change of paradigm which highlights a benefit for mankind related to the increase of plant feeding and crops yields by enhanced CO2 photosynthesis is suggested.

I strongly recommend a download and careful reading of the paper.

Why More USA CO2 is a Good Thing

Science Matters

A new editorial at Investor’s Business Daily explains: Don’t Join The Media Freak Out Over Recent Jump In CO2 Emissions — It Won’t Last. Excerpt in italics with my bolds.

CO2 Emissions: For the first time in years, U.S. carbon dioxide output rose last year, a new report says. The jump has set off alarms in all the predictable media quarters. Relax. It’s a great sign for the economy, and will mean nothing long term for the environment.

CO2, the main greenhouse gas that global warming advocates most fear, happens to be rising around the world right now. It has been for decades.

But in recent years the U.S. has been the big exception to that trend, with declining amounts of CO2 spewed into the air from its industry. The reason for this is that, thanks to fracking, companies and utilities around the country are replacing coal with…

Study shows the Sahara swung between lush and desert conditions every 20,000 years, in sync with monsoon activity

Tallbloke's Talkshop

These climatic swings (cycles) were in sync with changes in the Earth’s tilt, say the researchers. They therefore believe ice ages are not the primary factor in these swings.

The Sahara desert is one of the harshest, most inhospitable places on the planet, covering much of North Africa in some 3.6 million square miles of rock and windswept dunes.

But it wasn’t always so desolate and parched, reports

More Tornadoes? Capital Weather Gang Plug Flawed NOAA Study

Severe and tornadic thunderstorms are spawned by strong temperature and pressure gradients. Warmer planet means lower continental temperature gradients; ergo–fewer strong tornadoes.


By Paul Homewood


As I noted earlier today, the Washington Post’s Capital Weather Gang have reported that last year is the first on record to have no EF-4 and EF-5 tornadoes in the US.

The Capital Weather Gang long ago sold their souls to the global warming religion, and are usually very loathe to admit that sometimes the weather might be better because of a bit of warming.

At the very end of the above article, they get in their little dig:

In fact the study they refer to is hopelessly flawed, as I proved at the time.

But just to rehash, this is the narrative Climate Central published in 2016:

The Dryer Gets Wetter

Guest Post by Willis Eschenbach

I keep reading that one of the things that we are already seeing (or that is predicted) is that the wet areas of the planet are getting wetter and the dry areas are getting dryer, viz:

I thought about that while reading a recent study called Rapid Drying of Northeast India in the Last Three Decades: Climate Change or Natural Variability? (Their conclusion, by the way, was that it was NOT from human actions, but instead that “the recent decreasing trend of NEI summer monsoon rainfall is, rather associated with the strong interdecadal variability of the subtropical Pacific Ocean“.)

So I went to the marvelous KNMI Climate Explorer and got the CRU TS 4.01 gridded precipitation dataset, which covers from 1901 through 2016 . I started by looking at the trend of the data since 1901.

Figure 1. Global rainfall, land-only, 1901 – 2016.

Now, there is a trend … but the increase in monthly rainfall is only 2 millimeters per century. This represents an increase of about an inch (25 mm) in the yearly average rainfall. Small.

Next, since the Indian study concerned the recent decades, I looked more closely at the average rainfall over that period. Figure 2 shows the average rainfall around the globe for the period 1980 through 2016.

Figure 2. Average rainfall, 1980 – 2016. Rainfall is shown on a 1° latitude by 1° longitude gridcell basis. All areas with over 2.2 metres/year are shown in darkest blue.

Here you can see the great deserts of the Sahara, the Gobi, the Atacama, and central Australia. You can also see the wet zones of the Amazon, the African rainforests, and Indonesia and Papua New Guinea.

Next, I looked at the individual trends for each 1°x1° gridcell over that same period, from 1980 through 2016.

Figure 3. Precipitation trends, monthly precipitation, millimeters/month per decade. Areas with trends greater than 7 or less than -7 mm/decade are shown in bright blue or bright red. Click to embiggen.

Here we can see the problem indicated in the Indian study, the drying of Northeast India.

Finally, using the combination of precipitation and precipitation trend data, we can see if it is true that the dry areas are getting dryer and the wet areas are getting wetter. Figure 4 shows a scatterplot of the two datasets.

Figure 4. Scatterplot, annual precipitation versus precipitation trend. The colored lines show the trends for the areas with varying amounts of rainfall, from dry to wet.

What this shows is that while the wetter areas are getting wetter, it is not true that the dryer areas are getting dryer. All areas are getting more rain. Not a lot more rain, of course, but more rain. Once again, the climate models are wrong.

And so one more beautiful climate myth runs aground on a reef of hard facts … the wet is getting wetter, but the dry isn’t get dryer—instead, the dry is getting wetter as well

Here, we’re in the “wetter” part of the equation, a rainy Christmas Eve. Well, since it’s 2:03 AM, I guess it’s actually a rainy Christmas morning … so the very best of wet Christmas morning wishes to everyone.
