A new study shows extreme heat events both in the summer and in the winter are increasing across the U.S. and Canada.

Organic compounds undergo drastic variations in their chemical composition as they transfer from the ocean’s surface to atmospheric aerosols which act as nuclei to form clouds.

The research co-led by Drs. Christelle Not and Benoit Thibodeau from the Department of Earth Sciences and the Swire Institute of Marine Science, The University of Hong Kong, highlights a dramatic weakening of the circulation during the 20th century that is interpreted to be a direct consequence of global warming and associated melt of the Greenland Ice-Sheet. 

A new federal report finds that climate change is affecting the natural environment, agriculture, energy production and use, land and water resources, transportation, and human health and welfare across the U.S. and its territories.

33W was a tropical depression when it crossed the southern and central Philippines. As it moved through the South China Sea over the last two days it strengthened into a tropical storm and was renamed Usagi. On Nov. 23, NASA-NOAA’s Suomi NPP satellite captured a visible image of the stronger storm on approach to Vietnam.

In a just published paper in the peer-reviewed journal Arctic Science, the researchers report they have documented the presence of polar bears, black bears and grizzlies in Wapusk National Park on the west coast of Hudson Bay in northern Manitoba.

“The science is clear. Without rapid cuts in CO2 and other greenhouse gases, climate change will have increasingly destructive and irreversible impacts on life on Earth. 

If you have a smartphone, you’ve likely received a severe weather alert warning of an impending flash flooding event, a tornado or a dangerous thunderstorm, and that’s in part thanks to information provided by the National Weather Service (NWS).

Warmth tipped the scales again last month, making it not only the 2nd hottest October on record, but also the 4th hottest year to date for the globe, according to a fresh analysis by scientists at NOAA’s National Centers for Environmental Information.

Droughts or heat waves have consequences that spread beyond farmers anxiously watching their fields; these fluctuations in crop yields can send shockwaves through local and global food supplies and prices.
