Small hibernating bat colonies need protection to prevent extinction
Between collisions with wind turbines and deadly white-nose syndrome, endangered Indiana bats may not have much of a chance of recovering, according to a recently published U.S. Geological Survey study.
Planned test site in Oregon could help answer the question, but will it survive Trump?
All eyes are on wind and solar these days, and rightly so, but ocean waves may play an even bigger role in humanity’s efforts to decarbonize energy production. Scientists and engineers in the Pacific Northwest may get a chance to show how that can happen with a new wave energy test facility in Newport, Oregon.
Last month, Oregon State University’s Northwest National Marine Renewable Energy Center today was awarded up to $40 million from the U.S. Department of Energy for the Pacific Marine Energy Center South Energy Test Site, which should be operational by 2020. It will be able to test wave energy “converters” that harness the energy of ocean waves and turn it into electricity. Companies around the world are already anticipating construction of the new facility to test and perfect their technologies, OSU officials say.

Federal biologists say they can boost the population of grizzly bears in the North Cascades ecosystem by relocating the predators from other areas. The National Park Service and the U.S. Fish and Wildlife Service this week released a draft plan (open for public comment), for increasing the total number of bears in the region to 200. Bt current estimates, only about 10 remain, too small a population to sustain itself. According to the draft plan, grizzly bears could be relocated from either northwestern Montana or south-central British Columbia.
“We’re happy to see the agencies taking a step in the right direction to restore grizzly bears to the North Cascades,” said Andrea Santarsiere, a senior attorney with the Center for Biological Diversity. “Without a helping hand, grizzly bears are likely to disappear from the Pacific Northwest.” Continue reading “Feds eye grizzly reintroduction in North Cascades”→
Antarctic ice shelves are melting fastern than ever and sea ice globally is the lowest on record since accurate measurements started.
Scientists working in Greenland have been stunned by the speed at which ice is retreating.
Sea ice is vanishing around the Antarctic Peninsula, and there are signs the West Antarctic ice sheet may be prone to disintegration.

It’s hard to really get your head around what it means that the Arctic ice cap is literally melting away, and perhaps even harder to imagine that massive tracts of Antarctic ice are also giving way to global warming. But the science is pretty clear: During other epochs of Earth’s geological history, at times when there were similar global temperatures and about the same amount of CO2 in the atmosphere, so much ice melted that sea level was at least 20 feet higher than today. Today’s Earth — our Earth — seems to be responding the same way. For all of December, the extent of global sea ice has set record lows every single day. The Arctic meltdown is well documented by more than 100 years of data. Around the South Pole, more and more studies are showing warm layers of water melting large coastal slabs of ice that hold back the almost unimaginable masses of ice on the Antarctic continent. The images in this set are just snapshots, but what’s happening out there is very real. Take #climateaction now.
Not all global warming is equal, according to scientists who just published new research on how some areas will warm much faster than others. The study, published in PLOS ONE, shows that the northeastern U.S. is already heating up much faster than the global average and will hit the 2 degree Celsius mark about 20 years before the global average climbs to that level.
Republicans apparently willing to use authoritarian tools in their war on the environment
By Bob Berwyn
The GOP-dominated Congress is flexing its political muscle with legislation that would override the Endangered Species Act by removing federal protection for wolves in the Great Lakes region and Wyoming, making the animals vulnerable to state-regulated trophy hunting and trapping.
