New Research Finds Climate Models Usually Do It Right

New climate research, conducted primarily in San Diego, reveals that a study of Earth’s temperatures during the last ice age confirms some widely held ideas about climate change. Lead author Alan Seltzer, a paleoclimatologist at the Wood’s Hole Institute of Oceanography, studied ancient water as a way to better understand never-before-recorded planetary temperatures. New Research […]

New information on acid formation may help refine atmospheric and climate models

May 13, 2021 Atmospheric acidity is increasingly established by organic acids, such as formic acid and carbon dioxide. The former contributes to the development of aerosol particles as a precursor to raindrops and thus affects the pH of rainwater and cloud growth.. Diagram of the main emission sectors and primary emissions, meteorological and chemical processes, […]

To improve climate models, an international team turns to archaeological data

Climate modeling is forward-looking, its general intention to hypothesize what our planet might look like at a later date. Because Earth’s vegetation influences climate, climate models frequently include reconstructions of vegetation and are often validated by comparisons with the past. Yet such models tend to be oversimplified, obscuring or omitting how people affected the land […]

Tibetan Plateau may warm faster in future than climate models predict

Apr 7, 2021 In recent decades, the Tibetan Plateau, called “the roof of the world”, has warmed faster than the world average. Projected future warming of the Tibetan plateau in the CMIP5 ensemble. The thick lines indicate the multi-model ensemble means, and the shadows indicate the 90% model intervals, derived from the raw model output. […]

How to use climate models

The new report from the Australian Academy of Sciences, The risks for Australia of a 3 ° C hotter world, has grim predictions for the nation’s future under current carbon emissions policy and action. All of these predictions are based on climate models. Among the now familiar predictions of ecological and economic damage, the report […]
