What we can learn from 40 years of satellite temperature measurements

“What the graph shows is the departure from the average for the 30 years from 1981 to 2010. The last data point is February 2019 with a result of -0.03 degrees C. So we have had 40 years of global warming and the temperature has remained flat. In fact it is slightly cooler than the long term average. Is it possible to believe in global warming when the atmosphere has cooled? No, not rationally. Is it possible for global warming to be real if the atmosphere has cooled? Again no.” click here

NASA attempts to rewrite Iceland climate history

“The Arctic is very important for people pushing global warming, because that is where they claim most of the warming is occurring.

In NASA GISS Version 2 (V2) – Iceland was warmer in the 1940s than in recent years.” click here

Questions raised about Washington State use of public funds for climate advocacy further justification for Presidential Climate Commission

“Public records also show that your Office is transferring hundreds of thousands of dollars per year in taxpayer money, including apparently a quarter of a million Washington State taxpayer dollars, to pay consultants also to promote your climate advocacy and platform (Contract Number K2191).” click here

Professor Peter Ridd (David) vs James Cook University (Goliath)

“We finally got home from Brisbane where the court hearing was held about 1200 km to the south, and it has been good to reflect on events. I am very hopeful and Judge Vasta seemed to indicate that he would try to hand down his judgement around Easter. So, until then we should wait and see.” click here

Solar activity drove a significant percentage of recent warming

Nicola Scafetta and Richard C. Willson. Comparison of Decadal Trends among Total Solar Irradiance Composites of Satellite Observations. Advances in Astronomy Volume 2019,

We present a new analysis of the two-decade-old controversy over interpretation of satellite observations of total solar irradiance (TSI) since 1978 and the implications of our findings for TSI as a driver of climate change. Our approach compares the methods of constructing the two most commonly referenced TSI composites (ACRIM and PMOD) that relate successive observational databases and two others recently constructed using a novel statistical approach. Our primary focus is on the disparate decadal trending results of the ACRIM and PMOD TSI composite time series, namely, whether they indicate an increasing trend from 1980 to 2000 and a decreasing trend thereafter (ACRIM) or a continuously decreasing trend since 1980 (PMOD). Construction of the four-decade observational TSI composites from 1978 to the present requires the use of results from two less precise Earth Radiation Budget experiments (Nimbus7/ERB and ERBS/ERBE) during the so-called ACRIM-Gap (1989.5–1991.8), between the end of the ACRIM1 and the beginning of the ACRIM2 experiments. The ACRIM and PMOD composites used the ERB and ERBE results, respectively, to bridge the gap. The well-established paradigm of positive correlation between Solar Magnetic Field Strength (SMFS) and TSI supports the validity of the upward trend in the ERB results and the corresponding decadal upward trend of the ACRIM composite during solar cycles 21 and 22. The ERBE results have a sensor degradation caused downward gap trend, contrary to the SMFS/TSI paradigm, that biased the PMOD composite decadal trend downward during solar cycles 21 and 22. The different choice of gap bridging data is clearly the cause of the ACRIM and PMOD TSI trending difference, agreeing closely in both magnitude and direction. We also analyze two recently proposed statistical TSI composites. Unfortunately their methodology cannot account for the gap degradation of the ERBE experiment and their resulting uncertainties are too large to uniquely distinguish between the trending of the ACRIM and PMOD composites. Our analysis supports the ACRIM TSI increasing trend during the 1980 to 2000 period, followed by a long-term decreasing trend since.

Fact-check the AP on climate

“Borenstein, the chief climate reporter for the Associated Press, has a long history of promoting dubious climate claims and essentially lobbying the public to “believe” that man-made climate change is a dire emergency and that government “solutions” are needed.” click here

EPA Administrator Wheeler offers a responsible, measured response on climate change

Hysteria over climate changes is counterproductive. Climate is a dynamic system and is always changing. 

“On the climate change, it is an important issue that we have to be addressing, and we are addressing it, but most of the threats from climate change are 50 to 75 years out.” click here
