Some of the largest and fastest global climate changes in the geological record are associated with the Milankovitch cycles.

However, this time period has been cherry-picked to show “remarkably little” warming.Below is their graph overlain on the full satellite record (which began in 1978). That changed during the years 1988-1994, when climate research centered on CO2 and global warming received a 15-fold increase in funding in the US alone.
As Richard Lindzen has stated for years, the models fail to capture changes in clouds including changing cloud area and that the sizes of clouds are too small for grid scale modeling. 2020 SkS Weekly Climate Change & Global Warming News Roundup #26; Saharan dust storm expected to cause dangerous air pollution in U.S. this week; Archives. Published in PragerU, by Richard Lindzen on 8 May 2020 Three scientists analysed the article and estimate its overall scientific credibility to be ‘very low’. Richard Siegmund Lindzen (born February 8, 1940) is an American atmospheric physicist known for his work in the dynamics of the middle atmosphere, atmospheric tides, and ozone photochemistry.He has published more than 200 scientific papers and books. At the 18-second mark, the video shows a graph of what I believe are satellite-derived monthly temperature anomalies. Von 1983 bis zu seiner Emeritierung 2013 war er Professor für Meteorologie in der Abteilung für Erd-, Atmosphären- und Planetenwissenschaft am Massachusetts Institute of Technology (MIT). more about the credibility rating A majority of reviewers tagged the article as: Inaccurate, Misleading. Doubling the atmospheric CO2 concentration from 280 ppm to 560 ppm results in just a 1-2% perturbation to the Earth’s 240 W/m² energy budget.

‘Warming of any significance ceased about 20 years ago, and 2C warming was looking increasingly unlikely.’ Professor Richard Lindzen slammed conventional thinking on global warming as ‘nonsense’ […] A causal role for CO2 “cannot be claimed” for the glacial-to-interglacial warming events because CO2 variations follow rather than lead the temperature changes in paleoclimate records and the 100 ppm total increase over thousands of years produce “about 1 W/m²” of total radiative impact.3. Zuvor war er an der University of Chicago (1967–1972) und an der Harvard University (1972–1983) tätig.
The full satellite record shows that extending their graph in either direction (forward or backward in time) would reveal a clear warming trend.When these satellite derived temperature products (RSS and UAH in the graph below) are displayed as annual values and plotted on the same axis as the instrumental temperature datasets (Met Office, NASA and NOAA in the graph below), they largely agree with each other. Dr. Richard Lindzen retired several years ago, and yet his immense contribution to the atmospheric sciences lives on.

In particular, they all show the same large (in a geological context) rate of warming over the past several decades:Overall, Dr. Lindzen makes both a verbal claim and a visual claim that the rate of contemporary global warming is small, and both claims are false.We depend on your support to operate. His research is still cited about 600 times per year.

From 1983 until his retirement in 2013, he was Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology. And yet we are asked to accept the “implausible” claim that change in one variable, CO2, is predominantly responsible for altering global temperatures.2. His research is still cited about 600 times per year.
