Warming, sea-ice loss: Arctic Report Card tracks region's environmental changes

Tue, 11 Dec 2018 12:11:07 EST ~ NOAA's annual report card on the Arctic, released today, shows that the Arctic region experienced the second-warmest air temperatures ever recorded; the second-lowest overall sea-ice coverage; lowest recorded winter ice in the Bering Sea; and earlier plankton blooms due to early melting of sea ice in the Bering Sea.

Degrading permafrost puts Arctic infrastructure at risk by mid-century

Tue, 11 Dec 2018 11:30:30 EST ~ Seventy percent of the current infrastructure in the Arctic has a high potential to be affected by thawingpermafrost in the next 30 years. Even meeting the climate change targets of the Paris Agreement will not substantially reduce those projected impacts, according to a new study. Find out more...

ICESat-2 reveals profile of ice sheets, sea ice, forests

Tue, 11 Dec 2018 11:30:00 EST ~ With each pass of the ICESat-2 satellite, the mission is adding to datasets tracking Earth's rapidly changing ice. Find out more...

Sierra snowpack could drop significantly by end of century

Tue, 11 Dec 2018 09:06:39 EST ~ A future warmer world will almost certainly feature a decline in fresh water from the Sierra Nevada mountain snowpack. Now a new study that analyzed the headwater regions of California's 10 major reservoirs, representing nearly half of the state's surface storage, found they could see on average a 79 percent drop in peak snowpack water volume by 2100.

Switching to a home battery won't help save the world from climate change

Tue, 11 Dec 2018 08:09:29 EST ~ Home energy storage systems might save you money, but under current policies, they would also often increase carbon emissions. Find out more...

Ocean fertilization by unusual microbes extends to frigid waters of Arctic Ocean

Mon, 10 Dec 2018 16:51:18 EST ~ Microbes that provide natural fertilizer to the oceans by 'fixing' nitrogen from the atmosphere into a form useable by other organisms are active in the cold waters of the Bering and Chukchi Seas. Find out more...

Bioenergy crops could be as bad for biodiversity as climate change

Mon, 10 Dec 2018 16:51:06 EST ~ A large scale expansion in bioenergy crop production could be just as detrimental to biodiversity as climate change itself, according to new research. Find out more...

How will the winds of climate change affect migratory birds?

Mon, 10 Dec 2018 15:18:57 EST ~ Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years.

Humans may be reversing the climate clock, by 50 million years

Mon, 10 Dec 2018 15:06:14 EST ~ Our future on Earth may also be our past. Researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years. And it's taken just two centuries. Find out more...

A glimmer of hope for the world's coral reefs

Mon, 10 Dec 2018 11:56:26 EST ~ The future of the world's coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a new study, the response of the Great Barrier Reef to extreme temperatures in 2017 was markedly different to one year earlier, following two back-to-back bouts of coral bleaching.
