Fidelity of El Niño simulation matters for predicting future climate

A new study led by University of Hawai’i at Mānoa researchers, published in the journal Nature Communications this week, revealed that correctly simulating ocean current variations hundreds of feet below the ocean surface – the so-called Pacific Equatorial Undercurrent – during El Niño events is key in reducing the uncertainty of predictions of future warming in the eastern tropical Pacific.

Cold Air Rises – How Wrong Are Our Global Climate Models?

From Scitechdaily By University of California Davis May 6, 2020 The lightness of water vapor buffers climate warming in the tropics. Conventional knowledge has it that warm air rises while cold air sinks. But a study from the University of California, Davis, found that in the tropical atmosphere, cold air rises due to an overlooked…

Fauci-Birx climate models?

Honest, evidence-based climate models could avoid trillions of dollars in policy blunders Paul Driessen and David R. Legates President Trump and his Coronavirus Task Force presented some frightening numbers during their March 31 White House briefing. Based on now 2-week-old data and models, as many as 100,000 Americans at the models’ low end, to 2.2…

More Junk Science From the AAAS of A: Bird Apocalypse Edition

Guest Science! (as in “she blinded me with”) critique by David Middleton One of the best things about my morning emails from the American Association for the Advancement of Science of America (Google “Dodgeball” if you don’t get the joke), is that there’s almost always at least one article deserving of ridicule… Many state birds…

Weekly Climate and Energy News Roundup #279

  Brought to You by SEPP (www.SEPP.org) THIS WEEK: By Ken Haapala, President, Science and Environmental Policy Project (SEPP) Data Quality – Surface Temperatures: Writing in Energy Matters, Roger Andrews has begun an examination of efforts to adjust measurements to a preconceived idea. His first part deals with land-based, surface-air temperatures (SAT). Ideally, these are taken…

Could spraying particles into marine clouds help cool the planet?

From Eurekalert Public Release: 25-Jul-2017 University of Washington The idea of geoengineering, also known as climate engineering, is very controversial. But as greenhouse gases continue to accumulate in our atmosphere, scientists are beginning to look at possible emergency measures. A new University of Washington study looks at the idea of marine cloud brightening, which a…

Mechanical Models

Guest Post by Willis Eschenbach [NOTE the update at the end of the post.] I’ve continued my peregrinations following the spoor of the global climate model data cited in my last post. This was data from 19 global climate models. There are two parts to the data, the inputs and the outputs. The inputs to…
