Heat loss form Earth’s interior responsible for sliding ice sheets

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

From the “Who would have guessed that Department”:

Jan. 22 (UPI) — New research suggests the dissipation of heat from Earth’s interior is responsible for the acceleration of the seaward slide of Greenland’s ice sheets.

The descent of of Greenland’s shrinking glaciers is well documented, but the latest research — published this week in the journal Scientific Reports — is the first to link the ice loss with escaped heat from Earth’s interior.

The research was made possible by a decade-long survey of Greenland’s Young Sound fjord. For ten years, scientists with the Arctic Research Centre, Aarhus University and the Greenland Institute of Natural Resources measured temperatures and salinity levels in the fjord. Their survey showed deep-lying water in the fjord, between 650 and 1,100 feet deep, has gradually warmed over the last decade.

Further analysis showed a significant amount of heat is emanating from Earth’s interior…

Rupert Darwall: Europe’s Energy Crack-Up

Tallbloke's Talkshop

biomassExcerpt from National Review.  Whichever way you look at it, burning the world’s carbon sinks to meet the EU’s arbitrary renewable-energy targets is environmentally insane. Not only will the voracious appetite of Europe’s power stations for American timber threaten valued woodland habitats in forests across Louisiana, Georgia, Florida, Alabama, and Virginia, it has damaging economic effects, as it pushes up the price of timber, with knock-on effects to the cost of building new homes. Without question, it is better for the environment to burn coal and plant trees than to cut down trees and burn them in power stations.

The Cosmogenic Isotope Record and the Role of The Sun in Shaping Earth’s Climate

The defining division between “climate sceptics” and “greenhouse gas warmists” is the role of the Sun in causing Earth’s climate to oscillate. The anecdotal evidence for a significant solar role comes from the observation that during the Little Ice Age (LIA) sunspots were virtually absent from the Sun for a few decades – and in Europe at least it was periodically very cold. The HARD scientific evidence that backs this up comes from cosmogenic isotope variations that provide a record of solar geomagentic activity. It is surprising therefore that The Geological Society of London’s (GSL) 2010 position statement on climate change does not mention the incredible cosmogenic isotope record at all.

The omission was corrected in the 2013 addendum but unfortunately the addendum  does not fully represent what the cosmogenic isotope record tells us. This post is a response to the GSL’s addendum, at 3,700 words too long to include as a comment on the original post.

Extensive sea ice and northerly winds must have played a role in the common visits of Inuit to Scottish shores at these times. He was accompanied by ice bergs that drizzled sediment on the ocean floor leaving an amazing record for geologists to study.]

On the Precautionary Principle

Watts Up With That?

Guest essay by Neil Lock

Today, I’m going to look at a mantra much trumpeted by environmentalists; the precautionary principle. I’ll seek to make a case that, since the early 1980s, this idea has been perverted. To such an extent, that the principle now has an effect all but opposite to its true intention. I’ll trace how this happened, and try to outline how we might fix the resulting mess.

What is the precautionary principle?

The precautionary principle, even in its original, pre-1980s form, is an elusive beast. There’s no generally agreed wording of it. But its essence can be summarized as “better safe than sorry,” or “look before you leap.” Though some – myself included – go further, and see it as akin to the Hippocratic oath for doctors: “First, do no harm.”

In this form, the principle is very sensible advice. Before they put a new product on…

Blog uses my polar bear info but no link to PBS means they are ‘science-based’

polarbearscience

According to Harvey and colleagues (2017), any internet posting that discusses polar bears without a link to PolarBearScience or a mention of my name can be considered a ‘science-based’ blog. But they missed an obvious catch: bloggers who use my content without attribution.

Churchill Polar Bears dot org_header

For example, so-called ‘science-based’ blog Churchill Polar Bears, written by Churchill polar bear guide Steve Seldon, used text and two of the four figures provided in a 15 February 2017 post at PolarBearScience to create aChurchill Polar Bearspost on 17 February but did not include a single link to PolarBearScience indicating that’s where he got his information (Wayback machine link here).

Churchill polar bears blog headline 17 Feb 2017

A few would not consider this plagarism but most do. That is to say,failure to attribute a source when work or information is not your own is a big no-no in science, as it is in all of academia.

Nature Unbound VII – Climate change mechanisms

Climate Etc.

by Javier

Climate variations that alter the angular momentum of the atmosphere modify the speed of the Earth’s rotation, which affects the length of day (LOD). Alterations in LOD integrate different climate-affecting phenomena, and can anticipate turning points in climate.

Ten January Days in Baffin Bay

Science Matters

Sea ice forming in Baffin Bay.

Slowly but surely ice is building up on the Arctic Ocean fringes.  Baffin Bay in the center is shown growing ice the last ten days, while Gulf of St. Lawrence fills in on the left.

Meanwhile on the Pacific side, Okhotsk on the left is filling in normally, while Bering is starting to catch up.

Click on image to enlarge.

Overall 2018 Arctic ice has reached 13.5M km2, about 500k km2 or 4% below average. The deficit comes half each from Barents and Bering Seas. Two months remain to reach annual maximum with the standard this decade being about 15M km2.

Forecaster, father, and friend of WUWT, John Coleman passes away

RIP John.

Watts Up With That?

It is with great sadness that I announce this. John Coleman was a true hero of mine, and a great friend. He made gigantic contributions to television, to weather forecasting, and even to the National Weather Service who changed and upgraded many of their methods to accommodate the visionary ideas he had in founding the Weather Channel.

In 1983, Coleman won the American Meteorological Society award for Outstanding Service by a Broadcast Meteorologist. The organization credited Coleman for “his pioneering efforts in establishing a national cable weather channel,” according to the AMS website.

I last saw John Coleman a couple of months ago in Chicago at a gathering of TV meteorologists and climate skeptics. He was as jovial and as witty as ever.

To say “he will be missed”, is an understatement.


From NBC, San Diego,

John Coleman, the jovial and energetic meteorologist who delighted San Diego television viewers for…

What do the Ice Core Bubbles Really Tell Us?

Watts Up With That?

Guest Opinion: Dr. Tim Ball

At a recent public presentation titled “Whither the Weather” the most frequently asked question popped up once gain. “How do they know the temperatures from thousands of years ago, as in the Antarctic ice record.” I gave the standard answer about layers of ice, extraction of air from trapped bubbles and then comparison of the Oxygen 16/18 isotope ratio, which varies with atmospheric temperature. As always, people are dazzled by that, and even though they don’t understand, it sounds plausible. The trouble is that every time I give the answer, it triggers my long-term concerns about the nature of glaciers, glacial ice, entrapment of the bubble, and recovery methods of the air in the bubble. I spent hours discussing all aspects of glaciers and ice cores with the late Dr. Fritz Koerner, one of the few people to study glaciers in the Arctic and…

NASA – 2017 was 2nd warmest year, NOAA says 3rd warmest, El Niño a major warming influence

Watts Up With That?

From NASA Goddard:

Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by NASA.

Continuing the planet’s long-term warming trend, globally averaged temperatures in 2017 were 1.62 degrees Fahrenheit (0.90 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. That is second only to global temperatures in 2016.

Video: Earth’s surface temperatures in 2017 were the second warmest since since 1880, when global estimates first become feasible, NASA scientists found. Global temperatures 2017 were second only to 2016, which still holds the record for the hottest year; however, 2017 was the warmest year on record that did not start with an El Nino weather pattern, as the previous two years did. In a separate, independent analysis, NOAA scientists found that 2017 was the third-warmest year in their record…
