NASA: Coolants Contribute to Ozone Depletion and are strong Greenhouse Gases

According to a new NASA study, a class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion by a small but measurable amount, countering a decades-old assumption. A class of widely used chemical coolants known as hydrofluorocarbons (HFC) contributes to ozone…

Tropospheric Ozone in the Anthropocene: Are We Creating a Toxic Atmosphere?

Published on Feb 19, 2014: Jack Fishman explains how elevated ozone levels damage plants, affecting crop yields. Factors among ozone levels include, precipitation and temperature. Further studies found that yields present a consistent function depending on the ozone concentrations. Laboratory simulations suggest that the findings of the yield decline are a trend, which is projected…

Volcanic Eruptions Add to Larger Impact on Climate

The recent slow down in global warming has been attributed to a number of factors, including excess heat being stored in the deep ocean and reductions of certain greenhouse gases. Now add volcanic eruptions to the mix of contributing factors. A new analysis published in Nature Geosciences on Sunday shows that a series of relatively small…

Stronger Winds Shift Heat to Deeper Pacific

Published on Feb 9, 2014 Heat stored in the western Pacific Ocean caused by an unprecedented strengthening of the equatorial trade winds appears to be largely responsible for the hiatus in surface warming observed over the past 13 years. New research published in the journal Nature Climate Change indicates that the dramatic acceleration in winds…

White House: The Polar Vortex Explained in 2 Minutes

by Becky Fried | January 08, 2014  | Release URL Here at the White House, while we’re beginning to thaw from this week’s bone-chilling deep freeze, our discussions about the science of weather extremes are heating up. We know that no single weather episode proves or disproves climate change. Climate refers to the patterns observed in the weather…

The Science of the Polar Vortex and Jet Stream

At least since around 2001 we have study papers connecting the polar vortex / jet stream behavior to anomalies, such as cold weather outbreaks or precipitation changes. The polar vortex phenomenon was described as early as 1853. In recent years studies linked changes in the cryosphere to the polar vortex. Feel free to suggest further study papers in the comments.…
