by Judith Curry | February 8, 2021 Spatial Requirements of Wind/Solar and Nuclear Energy and Their Respective Costs “In addition to the energy sector, the climate debate also needs a transition. From ideology and wishful thinking, to facts, figures and rationality.” An important document was published last week, a collaborative instigated by two members of the European Parliament – one from the Netherlands and the other from Czechoslovakia.  One of the editors on the resulting report is Lucas Bergkamp, who has written several guest posts at Climate Etc. The study is now available for download on the website www.roadtoclimateneutrality.eu. This …

The Chinese team collected coral reef samples from Yongle (pictured) and Yongxing in the Paracel Islands. Xinhua Investigation of coral reefs in the Paracel Islands suggest the South China Sea began warming up in 1825, researchers say Uranium dating shows samples have a continuous climate record going back to 1520 South China Morning Post | Stephen Chen | 7 Feb, 2021 Studies of coral reefs in the Paracel Islands suggest that the South China Sea started warming up in 1825, at the start of the industrial revolution, according to a study by Chinese scientists. That was the year the world’s …

Postil Magazine October 1, 2019 | B.E. Vaillant   Is fame random? Or, is fame the result of access to power? The recent prominence of Greta Thunberg is a case in point. Did she become famous for simply being photographed sitting alone in front of the Swedish parliament building, on strike for the environment? Or, did she inherit the mantle of an eco-prophet? Is she just an ordinary, outraged young woman, or someone with deep family links to environmentalism, and who thus has all the right connections? For those that might not know, Greta supposedly shot to fame when the …

Professor Happer discusses CO2 and Bad Press  WUWT by Charles Rotter | Sept. 4, 2020 Professor Happer discusses CO2 and Bad Press CO2 is a greenhouse gas, just not a strong one.  Professor Happer discusses why the impact of CO2 is small on the earth surface temperature.   The effect of CO2 saturates as the amount of CO2 increases even to the 2X amount, such that the change in temperature is small.  It is not likely to see the impact of 2x CO2 above 1 to 1.5 C.  Exaggeration expands this impact greatly using feedback to achieve the artificial runaway warming.   …

By: Ken Haapala, President, Science and Environmental Policy Project (SEPP) http://www.sepp.org/ Logarithmic Relationship: A post in No Tricks Zone on earth’s climate being governed by the Sun led TWTW to search for a 1971 article on global cooling by S.I. Rasool and Stephen Schneider, then of NASA-GISS, now both deceased. Rasool was an atmospheric chemist who has written on the atmospheres of other planets as well as the earth. Stephen Schneider was a climatologist who was a lead author of the Third Assessment Report (TAR, 2001) of the UN Intergovernmental Panel on Climate Change (IPCC) and a strong advocate for …

WUWT Anthony Watts | Feb. 3, 2021 Just a couple of days ago, climate scientist Dr. Roy Spencer suggested U.S. Warming Trends could be largely spurious. In his analysis, Dr. Spencer examined another dataset maintained by the National Oceanic and Atmospheric Administration (NOAA) and found that when adjusted for population density, weather stations used to measure climate trends report lower long term temperature trends: “… the highest population density stations had ~0.25 C/decade warming trend, with a reduced warming trend as population density was reduced…” He adds: “Significantly, extrapolating to zero population density would give essentially no warming in the United …

January 29th, 2021 by Roy W. Spencer, Ph. D. Several lines of evidence suggest observed warming trends are not nearly as large as what you have been told. It’s been almost eight years since I posted results on my analysis of the global Integrated Surface Database (ISD) temperature data. Despite finding evidence that urbanization effects on temperature measurements have not been removed from official land temperature datasets, I still refer people to the official products (e.g. from NOAA GHCN, HadCRUT, etc.). This is because I never published any results from my analysis. But I’ve started thinking again about the question, …
