Scientists have wondered for decades why marine animals that live in the polar oceans and the deep sea can reach giant sizes there, but nowhere else.

Contrary to what you may have been taught, water doesn’t always freeze to ice at 32 degrees F (zero degrees C). 

University of California scientists think they know why Earth’s generally warm and balmy climate over the past billion years has occasionally been interrupted by cold snaps that enshroud the poles with ice and occasionally turn the planet into a snowball.

When heavy rain falls over the Indian Ocean and Southeast Asia and the eastern Pacific Ocean, it is a good indicator that temperatures in central California will reach 100 F in four to 16 days, according to a collaborative research team from the University of California, Davis, and the Asia-Pacific Economic Cooperation (APEC) Climate Center in Busan, South Korea. 

 As part of an international research collaboration, Queen’s University scientist and lead Canadian researcher Laura Thomson examined the contribution of Canadian glaciers and ice caps to global sea level rise.

Evidence of historic marine life present in Alaskan permafrost is helping scientists reconstruct ancient changes in the ice cover over the Arctic Ocean.

How wildlife will react to climate change is an open question, but one of the first studies to compare the responses of tropical mammals to warmer habitats suggests the answer won’t be as simple as “move to a cooler place.”

The Antarctic Peninsula is the northernmost part of the earth’s coldest continent, making it particularly vulnerable to a changing global climate.

Arctic temperatures are the warmest they’ve been in more than 10,000 years, according to a new University of Alberta study that highlights alarming rates of climate warming and thawing of permafrost in Northern Canada.

NOAA’s work with community partners restoring estuary habitat in Tillamook Bay, Oregon is revitalizing tidal wetlands for threatened Oregon Coast coho salmon, and helping reduce flooding in the surrounding communities and farmlands.
