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.
A federal recovery plan for endangered polar bears won’t halt the threat of climate change, but it could help dwindling populations of the great Arctic predators persist in the small patches of habitat that will remain after global warming melts most of the polar sea ice.
The plan, released Jan. 9, calls for reducing human-bear conflicts, collaboratively managing subsistence harvest, protecting denning habitat, and minimizing the risk of contamination from oil spills. Most of these actions are already underway, in partnership with Alaska Native communities, nonprofit groups, and industry representatives who participated in the plan’s creation. The plan also calls for increased monitoring and research. Continue reading “Feds finalize polar bear conservation plan”→
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.
In another Christmas-themed story, I reported on a Norwegian study that showed how widespread grazing by reindeer affects the reflectivity in northern tundra regions. It turns out that when the ungulates munch shrubs and brush, they make the world cooler: Save the Reindeer, Save the Arctic.
Another sign that we may be near a climate tipping point is research from California showing that some severely burned forests just aren’t regenerating at all. The fires have become so big and so intense that all the seed stock trees are destroyed, leaving big cleared areas where there is no source for new growth — except for shrubs and brush that quickly grow to dominate the landscape and prevent new seedlings from taking root: California Forests Failing to Regrow After Intense Wildfires.
And some people think that they don’t have to worry about climate change because they heard global warming slowed down between 1998 and 2012. Not so, according to scientists who recalculated the rate of warming in the world’s oceans to show there was no hiatus: Already Debunked Global Warming ‘Hiatus’ Gets Another Dunking.
As scientists learn more about the dynamics of the ocean around Antarctica, they’ve discovered a climate warming signal. Distinct layers of water, marked by temperature boundaries, are forming right now, leading to conditions similar to about 14,000 years ago, when Antarctic ice sheets melted rapidly, raising global sea level by more than 10 feet.

Ocean animals along the Atlantic coast of the U.S. will remain safe from excessive noise pollution at least for the foreseeable future, as President Obama last week moved to deny six permit applications for oil and gas exploration from Florida to Delaware — including requests to use intrusive seismic blasting.
New study tracks increase in summertime haze in Colorado wilderness
Longer and hotter droughts and wildfires are polluting the once clear blue skies of the high country in the West, according to new research from the University of Utah.
The study, published this week in the journal Environmental Research Letters, found a link between the severity of drought in the Intermountain West and summertime air quality. Climate projections suggest that drought and wildfire risk will continue to increase in coming decades.
