Another paper confirms “the pause” in global warming – cites issues with methods of obtaining average temperature

Spatiotemporal Divergence of the Warming Hiatus over Land Based on Different Definitions of Mean Temperature

  • Chunlüe Zhou & Kaicun Wang

Abstract

Existing studies of the recent warming hiatus over land are primarily based on the average of daily minimum and maximum temperatures (T2). This study compared regional warming rates of mean temperature based on T2 and T24 calculated from hourly observations available from 1998 to 2013. Both T2 and T24 show that the warming hiatus over land is apparent in the mid-latitudes of North America and Eurasia, especially in cold seasons, which is closely associated with the negative North Atlantic Oscillation (NAO) and Arctic Oscillation (AO) and cold air propagation by the Arctic-original northerly wind anomaly into mid-latitudes. However, the warming rates of T2 and T24 are significantly different at regional and seasonal scales because T2 only samples air temperature twice daily…

Tesla Battery, Subsidy, And Sustainability Fantasies

PA Pundits - International

By Paul Driessen ~

The first justification was that internal combustion engines polluted too much. But emissions steadily declined, and today’s cars emit about 3% of what their predecessors did. Then it was oil imports: electric vehicles (EVs) would reduce foreign dependency and balance of trade deficits. Bountiful oil and natural gas supplies from America’s hydraulic fracturing revolution finally eliminated that as an argument.

Now the focus is on climate change. Every EV sale will help prevent assumed and asserted manmade temperature, climate, and weather disasters, we’re told – even if their total sales represented less than 1% of all U.S. car and light truck sales in 2016 (Tesla sold 47,184 of the 17,557,955 vehicles sold nationwide last year), and plug-in EVs account for barely 0.015% of 1.4 billion vehicles on the road worldwide.

In recent months, Tesla sales plunged to nearly zero in Hong Kong and Denmark, as…

Study: Sea Level Rise Revised Downward

Watts Up With That?

Reposted from Roy Spencer’s Blog

July 21st, 2017 by Roy W. Spencer, Ph. D.

If I had not looked past the headline of the press report on a new study, I would have just filed it under “It’s worse than we thought”. A new study in Naturereported on July 17 carried the following headlines:

“Satellite snafu masked true sea-level rise for decades”
“Revised tallies confirm that the rate of sea-level rise is accelerating as the Earth warms and ice sheets thaw.”

When I read that, I (like everyone else) assumed that corrections to the satellite sea level data since 1993 have now led to a revised trend toward faster (not slower) sea level rise. Right?

Wrong.

During the satellite era (since 1993), the trend in sea level rise was revised downward, by almost 10%, from 3.28 mm/year to about 3.0 mm/year. (For those concerned about Miami going underwater, these…

More subsidies from exhausted California taxpayers cannot compensate for hard realities

Autopsy Of An Excuse

Watts Up With That?

Guest Post by Willis Eschenbach

Well, Dr. James Hansen, the man who invented the global warming scam and our favorite failed serial doomcaster, recently addressed the cratering of a 30-year prediction he made in 1988.

hansen_of_borg

Back then, he said the globe would warm up by two to five degrees by 2018 with five degrees being under the “business as usual” rubric … not. Here’s the story as written up in “Spin” magazine in 1988.

hansen 1998

Since then we’ve had a continued expansion of fossil fuel use, as in his most alarmist scenario. Given that amount of CO2 emissions, his prediction was that by now, temperatures would have gone up by five degrees Fahrenheit, or about 3°C.

Obviously, nothing like that has happened. Despite the fact that millions of folks believed his prediction in 1988 and continue to listen to him today, the UAH MSU satellite data says that since 1988 it’s…

The Foibles of Climate Research

Watts Up With That?

Government Created Misuse of Climate Research; Even a Little More Government is Not the Solution.

Guest opinion: Dr. Tim Ball

Environmental Protection Agency (EPA) Administrator Scott Pruitt wants to set up a Red and Blue team approach to climate research. It appears to be a commendable goal given the effective exclusion of one of the teams to date. The problem is it perpetuates another artificial division created by government involvement in climate science in the first place. David Middleton’s article comments on Pat Michaels’ proposed, “A Climate Roadmap for Pres. Trump” and identifies the legal problems of rescinding the US Supreme Court (SCOTUS) ruling on CO2 as a “harmful substance.” The EPA provided the ‘scientific’ definition used by SCOTUS, so the simple solution is for EPA to change it. Both stories miss the real issues. First, governments should not be involved in scientific research at all because, if nothing else…

Eemian and Holocene Climates

Science Matters

Hansen is publishing a new paper in support of the children suing the government for not fighting climate change. In it he claims temps now are higher than the Holocene and matching the Eemian, so we should expect comparable sea levels.

Paper is here:
http://www.earth-syst-dynam.net/8/577/2017/

Abstract. Global temperature is a fundamental climate metric highly correlated with sea level, which implies that keeping shorelines near their present location requires keeping global temperature within or close to its preindustrial Holocene range. However, global temperature excluding short-term variability now exceeds +1 °C relative to the 1880–1920 mean and annual 2016 global temperature was almost +1.3 °C. We show that global temperature has risen well out of the Holocene range and Earth is now as warm as it was during the prior (Eemian) interglacial period, when sea level reached 6–9 m higher than today. Further, Earth is out of energy balance with present atmospheric composition, implying…

Alarums And Excursions

Watts Up With That?

Guest Post hosted by Willis Eschenbach.

My friend Dr. Willie Soon is both a charming man and a most courageous scientist, who has taken a lot of heat for his principled stands on climate issues. He recently wrote a piece about climate alarmism along with Kesten Green and J. Scott Armstrong which deserves much wider circulation, which WUWT is glad to provide.

the sky is falling

My thanks to Drs. Green, Armstrong and Soon for the following important analysis.


Alarming Climate: Expert opinions and government funding versus scientific forecasting

Kesten C. Green, J. Scott Armstrong, and Willie Soon

July 14, 2017

On June 17, we and our co-authors received a response to our letter to MIT President, Professor Reif, raising concerns about his letter to the MIT community in support of the Paris Climate Accord. Professor Reif’s response stated that he was confident in his position on the issue because it is consistent with…

Stealth advocacy: a survey of weathercasters’ views on climate change

Climate Etc.

by Mike Smith

For a decade, the weathercaster and broadcast meteorology communities have been subject of a focused campaign to force them to cover global warming in a manner acceptable to the American Meteorological Society, the American Geophysical Union and other advocacy groups.
