Ocean Floor Warming Affects Antarctic Seabed Life

By Neha Jain @lifesciexplore A rise in ocean temperatures by 1°C may not seem like a lot. But researchers were surprised to find nearly doubled growth of some species with just one-degree rise in ocean warming and varied growth responses of assemblages with two degrees of warming, in the most realistic marine warming study conducted in Antarctica to date. These drastic changes in community structure may have huge consequences for the entire ecosystem, as they affect the food chain. “I was not expecting such a visible difference,” said Gail Ashton,…

Frequent Rainstorms Predicted with Climate Change

By Neha Jain @lifesciexplore If you live in California, you might recall the powerful winter rainstorm of 2014, dubbed the “storm of the decade.” While it offered some respite from the prolonged drought in the region, it dumped several inches of rain—in some Bay Area counties average annual rainfall was doubled—which caused widespread flooding and power outages. Until now such intense rainstorms have been rare. But in the future, Californians may need to clutch their umbrellas and slip on their rain boots more often because such monster rainstorms might become the…

What Happens When Antarctica Melts? Environment 

What Happens When Antarctica Melts?

By Kate Stone @GotScienceOrg Between December 2001 and February 2002, the Antarctic continent underwent a season of intense melting. Aside from the loss of ice, what really happens when Antarctica melts? New research reveals that the changes range from sped-up microbial food webs to shifting penguin populations. The clash of two climatic cycles, the Southern Annular Mode and the El Niño Southern Oscillation, produced an unusually warm and windy spring season across Antarctica back in 2001–2002. This climate event melted glaciers including the Totten Glacier, thinned lake ice, and caused…

Climate Change Strikes Totten Glacier in Antarctica

By Norman Rusin @normanrusin A warmer climate attacks polar glaciers at both ends of the Earth. In the Arctic, ponds of meltwater speed up the overall melting process, but in Antarctica, currents of warm water erode the ice sheet beneath the surface. Recent observations revealed that ice sheet erosion in two Antarctic regions is deep enough to expose basement rocks. At current rates, the erosion could trigger instability in a major Antarctic glacier, ultimately leading to more than 2 m (6.56 ft) of sea level rise. What Is a Grounding Line?…

Tracking Climate Change Through Hibernating Toads

By Neha Jain @lifesciexplore Have you ever wondered how animals are coping with warming temperatures? Our warming planet affects the migration, reproduction, and hibernation of animals that depend on the seasons to regulate these behaviors.  For example, new research finds that Fowler’s toads in Canada are emerging out of hibernation earlier each spring as the climate warms. Hibernating Toads Even though David Green, a professor at McGill University, Canada, had been studying Fowler’s toads for the past 25 years, the discovery of the toads’ early emergence from hibernation was quite…

Climate Change: Why Don’t We Worry More?

“If we could invent one risk that bypasses all of our psychological alarm systems, global climate change would be it,” a psychologist explains. You’ve seen the projections, read the articles about record annual temperatures, rolled your eyes at climate change deniers. You know the threat of global warming is real. At least intellectually. But are you really worried about it? Probably not as worried as you know you should be. We asked social psychologist Sander van der Linden of Princeton University why it’s so hard for our brains to perceive climate…

Small Metal Stove Grate Makes Big Impact

By Kate Stone The World Health Organization (WHO) estimates that 2.7 billion people worldwide still rely on wood fires to cook their food, and more than 4 million die each year from illnesses connected to household air pollution caused by that method of cooking. An inexpensive metal insert for primitive cookstoves, created by a University of Iowa research team, may decrease global warming and potentially save many lives. The insert decreases wood consumption by about 60 percent, and further testing  conducted in a national lab in India found that the…

Meltwater rivers gushing on top of the ice layers in Greenland Environment Uncategorized 

Greenland Ice Sheets Losing Ability to Absorb Meltwater

By Neha Jain Greenland Ice Sheets Losing Ability to Absorb Meltwater Sea-rise levels caused by a warmer Earth may be higher than predicted, according to a new study. Meltwater from ice sheets at the poles is often blamed for rising sea levels. Now, scientists have discovered some more grim news: Ice sheets in Greenland are losing their ability to retain meltwater, resulting in faster runoff of meltwater into the ocean. Meltwater from ice sheets does not always run off into the ocean. During summer when melting occurs, some of the…

More Heat Waves Predicted in Next 20 Years

By Kate Stone Scientists have developed a new method to more accurately measure and predict heat waves, and the results are frightening. More Heat Waves to Come The researchers have shown that heat waves are likely to increase both in severity and number during the next two decades. “Even if global mean temperatures don’t increase too much, we’ll see more extreme heat events. These will be hotter, longer, and more frequent,” explains Simone Russo from the European Commission Joint Research Centre, Ispra, Italy. The new metric is called the Heat…
