Scientists: “Antarctic ice sheet collapse now unstoppable”

NBC: The consequences of the warming planet are being quantified in a new report from ice researchers in the Antarctic. They say the collapse of the massive “West Antarctic Ice Sheet” has already begun, and the melting of this ice sheet into the ocean could raise sea levels by as much as 15 feet in the coming centuries. wo teams of scientists say the long-feared collapse of the West Antarctic Ice Sheet has begun, kicking off what they say will be a centuries-long, “unstoppable” process that could raise...

Climate Change Harms Fresh Water Quality

Chapelboro: A study published in Global Change Biology claims that the quality of fresh water is beginning to diminish in lower elevation forests, and that climate change is to blame. The director of the Institute for the Environment, and distinguished professor of geography at the University of North Carolina at Chapel Hill, Lawrence E. Band, states that the lower elevated watersheds are becoming greatly stressed due to the recent frequency of droughts in those areas. “If we become more dependent on upper...

Hotter nights may cause rice yields to fall

SciDevNet: Nights are getting hotter and scientists are sweating over the possibility that rice yields may fall as a result. Decreasing rice harvests mean higher prices. That would be a scary scenario in Asia where rice is considered not only a basic food staple but also a political commodity. Shortages of the commodity in 2007-2008 angered consumers across the region and caused some governments to wobble. A 35-year climate trending by the International Rice Research Institute (IRRI) under its Long-Term Continuous...

Canada: Will Toronto be resilient in the face of climate change?

Toronto Star: Toronto is celebrated for its diversity, but what about its resiliency? As the planet heats up and weather grows ever more extreme, cities around the world are taking a second look at themselves with an eye to making sure they’re up to the task ahead. So it was no surprise that the Global Cities Summit devoted a whole session to the subject of urban resiliency. The conference, one of the most international Toronto has hosted in some time, wrapped up Friday evening. Delegates from places as...

California Wildfires Spread Across Hills, Leveling Homes

New York Times: With fire rolling swiftly down the hill toward their houses on Thursday, Jeff Brown, his brother and his grandmother were forced by sheriff’s deputies to flee the two homes here that the family has occupied since the 1960s. Mr. Brown, 38, was back just an hour later. His house was untouched, but his grandmother’s home was gone — only the chimney still stood. “Damn, you can’t even tell there was a three-bedroom house here,” Mr. Brown said, as he walked across the property on Friday. “The trailer...

Methane emissions from fossil fuel exploitation may push Earth past climate tipping point

Summit Voice: As frackers desperately try to pump every last bit of gas from the ground before the global warming clock runs out, scientists warn that methane emissions could push Earth over a climate tipping point in just a few years. “We have to control methane immediately, and natural gas is the largest methane pollution source in the United States,” said Robert Howarth, greenhouse gas expert and ecology and environmental biology professor at Cornell University. “If we hit a climate-system tipping point...

Scientists vow to do a better job of portraying climate change

Pekin Daily Times: Following critical remarks made by Sen. Marco Rubio of Florida about the way scientists depicted the effects of human activity on climate change in the latest National Climate Assessment, the authors of the report are vowing to write a more compelling narrative the next time around. “We haven’t heard the senator question the science or the math in the report, so I think if we improve the story arc, possibly bring in a love interest of some sort, and a car chase, and organize the work in three,...

Emails Reveal North Carolina Officials’ Close Ties With Fracking Lobby Groups

EcoWatch: In North Carolina, Halliburton and other fracking industry interests helped write a fracking chemical disclosure bill. But when that bill ended up requiring disclosure of harmful chemicals to the state environmental agency, the bill was killed and replaced with one that further limited disclosure of the chemicals used in fracking. A cache of emails obtained by Greenpeace has revealed the cozy relationship between the hydraulic fracturing industry and North Carolina’s Mining and Energy Commission....

What’s To Blame California’s Early Fire Season?

National Public Radio: John Laird, the secretary of the California Natural Resources Agency, discusses how to fight fires differently, as well as the role climate change may play in the frequency of fires in California.

Future Ice Melt Patterns In Antarctica

Planetsave: One of the main impacts of climate change is sea level rise, brought about through melting of the world’s ice sheets and glaciers, as well as through thermal expansion of the oceans. The vast majority of world’s fresh water is locked up in the massive ice sheets covering Antarctica and Greenland. Of the two, Antarctica is by far the larger, holding about twelve times as much ice as Greenland. While the antarctic continent has not yet contributed a great deal to rising sea levels, it has the potential...
