A new study demonstrates that the naturally occurring warm-to-cold change in the tropical Pacific Ocean is the major cause for the recent intensification in Pacific Walker circulation, the most prominent feature of the tropical Pacific.

Ecologists estimate that 15 to 37% of plant and animal species will go extinct as a direct result of the rapidly changing climate.

A combination of vaccination and naturally acquired infection appears to boost the production of maximally potent antibodies against the COVID-19 virus, new UCLA research finds.

A new study shows that people who do vigorous physical activities, like jogging or playing competitive sports, in areas with higher air pollution may show less benefit from that exercise when it comes to certain markers of brain disease.

While climate change is the primary driver of permafrost degradation in Arctic Alaska, a new analysis of 70 years of data reveals that tundra fires are accelerating that decline, contributing disproportionately to a phenomenon known as “thermokarst,” the abrupt collapse of ice-rich permafrost as a result of thawing.

Across the U.S., road crews dump around 25 million metric tons of sodium chloride — much like table salt — to unfreeze roads each year and make them safe for travel.

There is growing public awareness that climate change will impact society not only through changes in mean temperatures and precipitation over the 21st century, but also in the occurrence of more pronounced extreme events, and more generally in natural variability in the Earth system.

Because plants take up carbon dioxide from the atmosphere and convert it into food, forests and other similar ecosystems are considered to be some of the planet’s most important carbon sinks.

Not to pile on, but winter is coming and the COVID-19 pandemic is about to get worse.

Methane, which produces more warming than other greenhouse gases and is the subject of newly announced U.S. emission restrictions, is hard to break down and keep out of the atmosphere.
