UAH finds a warming error in satellite data, lowers “tropical hotspot” temperature trend, contradicts IPCC models

Weather Satellite Wanders Through Time, Space, Causing Stray Warming to Contaminate Data

In the late 1990s, the NOAA-14 weather satellite went wandering through time and space, apparently changing the record of Earth’s climate as it went.

Designed for an orbit synchronized with the sun, NOAA-14’s orbit from pole to pole was supposed to cross the equator at 1:30 p.m. on the sunlit side of the globe and at 1:30 a.m. on the dark side, 14 times each day. One of the instruments it carried was a microwave sounding unit (MSU), which looked down at the world and collected data on temperatures in Earth’s atmosphere and how those temperatures changed through time.

Antarctic Temperature Data Contradict Global Warming…”Much Warmer” 105 Years Ago!

by P. Gosselin, April 3 , 2018 in NoTricksZone


Despite all the alarmist claims of an Antarctic meltdown, it is well known that the trend for sea ice extent at the South Pole has been one of growing ice rather than shrinking ice over the past 4 decades.

Naturally many factors influence polar sea ice extent, such as weather patterns, winds, ocean currents and sea surface temperature cycles. One factor of course is also surface air temperature, which according to global warming theorists is rising globally (…)

THIS WEEK: By Ken Haapala, President

California Litigation, Monckton: Last week’s TWTW discussed on the public nuisance lawsuits by San Francisco and Oakland against oil companies claiming carbon dioxide (CO2)-caused global warming / climate change will cause harm in the future. It focused on the filing amicus curiae (friend of the court) brief by three distinguished Professors of Physics – William Happer, Steven Koonin and Richard Lindzen (Three Profs). The brief accepted the data and evidence used by the UN Intergovernmental Panel on Climate Change (IPCC) in its Fifth Assessment Report (AR5) and the Climate Science Special Report (CSSR) by the US Global Change Research Program (USGCRP). However, the Three Profs demonstrate the conclusions in the reports are not established, and, at best, premature. They assert:

“Our overview of climate science is framed through four statements

Climate Science Integrity And Intelligence At All Time Record Low

By Tony Heller, April 1, 2018 in TheDeplorableClimSciBlog


With temperatures of -30C and Arctic sea ice nearing its winter maximum, government climate scientists and their useful idiots in the press announce that Arctic sea ice is “near an all time low.”

In the actual Arctic, sea ice extent is increasing, more than

double six months ago, and essentially identical to all recent years (…)


 

Another Bust: PAGES 2k ‘Global’ Reconstruction Fails To Confirm The ‘Hockey Stick’

Steve McIntyre Spots ‘Several Errors’ Corrupting Arctic 2k; Some Are Corrected In 2014

Steve McIntyre, known for his evisceration of the questionable data-collection processes in the construction of “hockey stick” graphs, identified several suspicious “errors” corrupting the Arctic data set.   He wrote about them on his blog.

Modern Warming – Climate Variability or Climate Change?

by  Renee Hannon, March 28, 2018 in WUWT


In the mid-1900’s many scientists were suggesting the Earth was cooling. Now scientists are forecasting global warming. Indeed, instrumental data shows global temperatures warmed by approximately 1-degree C during the past 165+ years. With warming rates of 0.5 to over 1.3 degrees C per century this has caused considerable alarm for many. This recent warming is commonly attributed to increasing greenhouse gases, primarily CO2.

This post examines natural paleoclimate trends and simple characteristics of past and present climate cycles at different time scales.

Another Icon Of Global Warming Drowns

by Tony Heller, March 27, 2018 in CimateChangeDispatch


The key to understanding this can be found in the 2004 Smithsonian article. The Tuvalu story (like everything else with global warming) has always been about left-wing politics and money, not science.

But not all scientists agree that Tuvalu’s future is underwater. Some critics have branded island leaders as opportunists angling for foreign handouts and special recognition for would-be “environmental refugees” who, they say, are exploiting the crisis to gain entry to New Zealand and Australia. Others have even said that people and organizations sympathetic to Tuvalu are “eco-imperialists” intent on imposing their alarmist environmental views on the rest of the world.

And of course the same fake story in the Maldives, which were supposed to be underwater by 2018.

BBC Regrets Climate Error And Failure To Meet Usual Standards Of Reporting — Then Does It Again

by P. Homewood, March 2, 2018 in NotaLotofPeopleKnowThat


Everybody makes mistakes, and some of them matter. On the BBC’s News at Ten on the 18th January 2018 there were two of them, and the GWPF complained a few days later.

The first error was in describing the global temperature of 2017 as the “hottest year on record,” which it wasn’t.

The second mistake was that the BBC’s Environment Analyst Roger Harrabin said that, “2017 had no heating from El Nino,” which was also incorrect.

We pointed out that whilst 2017 was not designated a year in which there was an El Nino event (defined as a period with prolonged El Nino heating) there was in fact El Nino heating in the northern spring for 11 weeks, and we provided a graph to prove it. (Click on image to enlarge)(…)

46 New (2018) Non-Warming Graphs Affirm Nothing Climatically Unusual Is Happening

by K. Richard, March 22, 2018 in NoTricksZone


During 2017, there were 150 graphs from 122 scientific papers published in peer-reviewed journals indicating modern temperatures are not unprecedented, unusual, or hockey-stick-shaped — nor do they fall outside the range of natural variability.

We are less than 3 months into the new publication year.  Already 46 new graphs from 40+ scientific papers undermine claims that modern era warming — or, in some regions, modern cooling — is climatically unusual.

Where The Warmth Is

by Willis Eschenbach, March 24, 2018 in WUWT


I got to thinking about the “hiatus” in warming in the 21st Century, and I realized that the CERES satellite dataset covers the period since the year 2000. So I’ve graphed up a few views of the temperature changes over the period of the CERES record, which at present is May 2000 to February 2017. No great insights, just a good overview and some interesting findings.

BBC Forced To Retract False Claim About Hurricanes

by P. Homewood, March 22, 2018 in NotaLotofPeopleKnowThat


You may recall the above report by the BBC, which described how bad last year’s Atlantic hurricane season was, before commenting at the end:

A warmer world is bringing us a greater number of hurricanes and a greater risk of a hurricane becoming the most powerful category 5.

 As I promised, I fired off a complaint, which at first they did their best to dodge. After my refusal to accept their reply, they have now been forced to back down.

The above sentence now no longer appears, and instead they now say:

Scientists are still analysing what this data will mean, but a warmer world may bring us a greater number of more powerful category 4 and 5 hurricanes and could bring more extreme rainfall.

Correction 29 January 2018: This story has been updated to clarify that it is modelling rather than historical data that predicts stronger and wetter hurricanes.

Arctic Ice Volume Growth Surprises As Solar Activity Approaches Near 200-Year Low

by F. Bosse and Prof. F. Vahrenholt, March 20, 2018 in NoTricksZone


The sunspot number for February 2018 was 10.6 and thus was some 30% below the meanfor this time into the cycle. At the moment solar activity is close to quiet.

Just 10 years ago, all the talk was about the Arctic sea ice “death spiral”, with some of scientists hysterically predicting the sea ice would soon disappear altogether in the summertime. Ten years later the scientists are now scratching their heads as sea ice has stabilized and is showing some clear signs of a rebound.

Since 2008, 0.24°C Of ‘Extra’ Warming Has Been Added To NASA’s 1910-2000 Global Temperatures

by K. Richard, March 19, 2018 in NoTricksZone


In the last 10 years, overseers of the NASA GISS global temperature data set have been busy utilizing cool-the-past-and-warm-the-present adjustment techniques to alter the slope of the overall warming trend.

For example, as the climate4you graph illustrates above, there was a +0.45°Cdifference between the 1910 temperature anomaly and the 2000 temperature anomaly as of May, 2008.

Today (March, 2018), NASA GISS has tendentiously adjusted up the difference between 1910 and 2000 to +0.69°C, a 53% increase.

Amstrup & colleages can’t refute my critique of their 2007 polar bear survival model, Part 2

by Polar Bear Science, March 12, 2018


Polar bear specialists Andrew Derocher and Steven Amstrup recently spent inordinate energy trying to refute the opinion piece I’d written for the Financial Post in celebration of International Polar Bear Day last month, ignoring my fully referenced State of the Polar Bear Report for 2017 that was released the same day (Crockford 2018) and the scientific manuscript I’d posted last year at PeerJ Preprints (Crockford 2017).
