National Academy of Sciences Declares Global Warming Contributes Hot and Cold Severe Weather

According to the National Academy of Sciences, if the weather is severe it is partly our own fault. “Global warming can contribute to the intensity of heat waves, drought, and wildfires. It also increases water vapor in the atmosphere, which can lead to more frequent heavy rain and snowstorms. #BasedOnScience”. But they forgot to explain their position appears to differ from the IPCC position.

Antarctic sea-ice models improve for the next IPCC report

University of Washington The world of climate modeling is complex, requiring an enormous amount of coordination and collaboration to produce. Models feed on mountains of different inputs to run simulations of what a future world might look like, and can be so big — in some cases, lines of code in the millions — they…

Plausible scenarios for climate change: 2020-2050

Reposted from Dr. Judith Curry’s Climate Etc. Posted on February 13, 2020 by curryja | by Judith Curry A range of scenarios for global mean surface temperature change between 2020 and 2050, derived using a semi-empirical approach. All three modes of natural climate variability – volcanoes, solar and internal variability – are expected to act…

Unsettled Climate Science: 30 Years Apace

Reposed from the Institute of Energy Research By Robert L. Bradley, Jr. February 14, 2020 Climate activist Emily Akin has called it “the most important climate story of the last 10 years: The quiet, concerted effort by fossil fuel interests to conceal and deny climate science, for the purposes of preventing climate action.” The bad…

Analysis of a carbon forecast gone wrong: the case of the IPCC FAR

Reposted from Dr. Judith Curry’s Climate Etc. Posted on January 31, 2020 by curryja | by Alberto Zaragoza Comendador The IPCC’s First Assessment Report (FAR) made forecasts or projections of future concentrations of carbon dioxide that turned out to be too high. From 1990 to 2018, the increase in atmospheric CO2 concentrations was about 25%…

Climate science has died. The effects will be big.

Reposted from the Fabius Maximus blog By Larry Kummer, Editor / 17 November 2019 Summary:  Let’s hit “pause” in the climate wars and see how we got here, where we are going, and what we can learn from this mess. “I can’t use this result. It doesn’t support the narrative.“ Photo 99364552 © Standret –…
