Tropical cyclone ‘maximum intensity’ is shifting toward the poles

As tropical cyclones move into higher latitudes, regions closer to the equator may experience reduced risk, while higher latitudes experience increased risk.

Over the past 30 years, the location where tropical cyclones reach maximum intensity has been shifting toward the poles in both the northern and southern hemispheres at a rate of about 35 miles, or one-half a degree of latitude, per decade according to a new study, The Poleward Migration of the Location of Tropical Cyclone Maximum Intensity, published tomorrow in Nature.

 

NOAA Researchers Contribute to The 3rd National Climate Assessment Revealing the Latest Impacts of Climate Change on the U.S.

We spoke with NOAA Research’s three contributing authors to the U.S. Global Change Research Program’s 3rd National Climate Assessment (NCA) released May 6, 2014 to understand their contribution to the NCA. According to the U.S. Global Change Research Program, the 3rd NCA is a compilation of scientific information on climate change from multiple sources and institutions and is a valuable resource in communicating and understanding climate change science and the impacts of climate change on the United States. The NCA will be used by federal scientists and managers, U.S. communities and citizens, and commercial businesses to improve environmental sustainability.

NOAA-led researchers discover ocean acidity is dissolving shells of tiny snails off West Coast

A NOAA-led research team has found the first evidence that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel and herring, according to a new paper published in Proceedings of the Royal Society B.

US Postal Service unveils new Earth Day stamp celebrating NOAA Climate Science

Stamp inspired by climate model showing Earth's sea surface temperatures

On April 22, 2014, the U.S. Postal Service is celebrating Earth Day by unveiling a new Forever international rate stamp inspired by a simulation of sea surface temperatures from a NOAA model of the Earth’s climate. The round stamp depicts the globe with North America in the center, surrounded by vivid bands of blue, green and red, signifying the varying temperatures of sea surface waters.
