NOAA Satellite records second largest 2-month temperature drop in history

UPDATE: Changed emphasis from Northern Hemisphere extratropics to entire Northern Hemisphere (h/t John Christy) In April, 2020, the Northern Hemisphere experienced its 2nd largest 2-month drop in temperature in the 497-month satellite record. The Version 6.0 global average lower tropospheric temperature (LT) anomaly for April, 2020 was +0.38 deg. C, down from the March, 2020…

Seeing what one expects

By Kevin Kilty This morning I awoke to a mid-April morning temperature of -11F. The 1981 to 2010 climate normals indicate our average daily minimum temperature per this date as about 23F, and the standard deviation as 8F. Thus, our morning low temperature is a 4-sigma event. Surely something to evoke comment. Yet, it did…

NOAA Relies on ‘Russian Collusion’ to Claim January Was Hottest Month on Record

Other data shows the USA wasn’t even close to a record. By Anthony Watts In a report generating substantial media attention this month, the National Oceanic and Atmospheric Administration (NOAA) claimed January 2020 was the hottest January on record. In reality, the claim relies on substantial speculation, dubious reporting methods, and a large, very suspicious,…

Global Temperature Report: October 2019

November 1, 2019 Vol. 29, No. 7 Global climate trend since Dec. 1 1978: +0.13 C per decade October Temperatures (preliminary) Global composite temp.:  +0.46 C (+0.83 °F) above seasonal average Northern Hemisphere.: +0.64 C (+1.15 °F) above seasonal average Southern Hemisphere.: +0.27 C (+0.49°F) above seasonal average Tropics.: +0.30 C (+0.54°F) above seasonal average…

‘Hidden’ NOAA temperature data reveals that 6 of the last 9 months were below normal in the USA – and NOAA can’t even get June right

A review of state-of-the-art climate data tells a different story than what NOAA tells the public. While media outlets scream “hottest ever” for the world in June and July (it’s summer) and opportunistic climate crusaders use those headlines to push the idea of a “climate crisis” the reality is for USA is that so far…

First ICESat-2 Global Data Released: Ice, Forests and More

From NASA Global Climate Change By Kate Ramsayer, NASA’s Goddard Space Flight Center More than a trillion new measurements of Earth’s height – blanketing everything from glaciers in Greenland, to mangrove forests in Florida, to sea ice surrounding Antarctica – are now available to the public. With millions more observations added each day, data from…

Analysis of new NASA AIRS study: 80% of U.S. Warming has been at Night

By Dr. Roy Spencer I have previously addressed the NASA study that concluded the AIRS satellite temperatures “verified global warming trends“. The AIRS is an infrared temperature sounding instrument on the NASA Aqua satellite, providing data since late 2002 (over 16 years). All results in that study, and presented here, are based upon infrared measurements alone, with…

The ‘trick’: How More Cooling Generates Global Warming

From the “we’ll fix that in post” department comes this from down under courtesy of Dr. Jennifer Marohasy. COOLING the past relative to the present has the general effect of making the present appear hotter – it is a way of generating more global warming for the same weather. The Bureau of Meteorology has rewritten…

Data analysis: Global temperature has not increased under Republican presidents, only Democrats

From the website Statistical Modeling, Causal Inference, and Social Science  at Columbia University comes this hilarious but real bit of data analysis. Looking at short trends in the global surface temperature data, the analysis shows that global temperature has not increased under Republican presidents, only Democrats. It’s probably spurious correlation, but still very entertaining. – Anthony…
