temperature changes

Previously rare extreme summer temperatures are occurring more frequently in some regions of the U.S.—especially in the Southwest, the upper tier of the Midwest, and the Atlantic coast—due to climate change, according to a new study in Climatic Change.

Scientists find that over the last 65 million years, waves of diversity in North American mammal species were profoundly influenced by changes in temperature.

West of the Rockies, temperatures were slightly below to well below normal this month, but regions of the Southwest east of Rockies saw temperatures near to slightly above average, according to the newest State of the Climate from NOAA.

The October State of the Climate report from NOAA shows U.S. temperatures were 0.9˚F above average, with eighteen states (including the Southwest) experiencing above-normal temperatures.

According to the newest Southwest Climate Outlook from CLIMAS, October temperatures were cooler than average in northern Arizona and New Mexico, while southeastern New Mexico and southern Arizona experienced above-average temperatures.

According to the newest State of the Climate by NOAA, September was 1.5°F warmer than average across the U.S. Average precipitation, on the other hand, was near normal with most of the eastern half of the U.S.

In a September 7 press conference, experts from the nonprofit Climate Communication project discussed the connection between global extreme weather and climate change. In recent decades, as the climate has warmed, extreme weather has become more frequent. This extreme weather (which the U.S.

Authors of a recent article in Climatic Change determined how a 1.2˚C global-mean temperature increase relative to present would affect the frequency of temperature extremes in the future.

An increase in the amount of particles in the stratosphere since 2000 appears to have reduced surface warming from increased emissions of carbon dioxide and other greenhouse gases, according to new research published in Science.
