IIt's hard to think of too many animals that could take out a grizzly bear.
At nearly 1,000 pounds and standing up to eight feet tall on its hind legs, the razor-toothed beast seems immune to all but the fiercest of contenders — and yet, one of the biggest threats to grizzlies is a tiny animal, hardly bigger than your fingernail.
Meet the mountain pine beetle.

I've witnessed this in BC - not a pretty sight, acres of land with dead pines, the forest creatures displaced and starving.
Some news networks ignored some of the year's most important climate and environment news entirely, while others gave disproportionate air time to talking heads who reject the basic scientific consensus on climate change.
A new analysis lays out several detailed “pathways” to a low-carbon future for the United States, and offers practical guidance for policy makers. The bottom line finding is that there are multiple ways we can significantly reduce greenhouse gas emissions,...
Michigan State University (MSU) Extension applies research from MSU to help Michigan residents solve everyday problems in agriculture, community development, nutrition, family finances, youth development and more.
Would you like to taste the health-giving grain found in the tomb of King Tutankhamun? Or feast on the unprocessed kernels said to have been stored on the ark by Noah? Or how about a vodka made from traditionally farmed Bolivian quinoa? If any of this whets your appetite, you are not alone.
The NOAA has just released a new report on the historic drought that has been affecting California for the last three years. Stunningly, investigators are saying that human-driven climate change is not to blame, and it is instead the consequence of natural phenomena.
If coal companies get their way when the Supreme Court reviews U.S. EPA's air standards for mercury and other hazardous emissions, they could undermine their primary legal challenge to another landmark pollution rule: President Obama's greenhouse gas limits for power plants.
Today, many serious “big green” environmental groups are looking at how the food system can reduce its emissions and how agriculture can be harnessed for the cause. Many food-focused groups are also increasingly seeing the work they do–to promote organic farming, to fight petrochemicals and synthetic fertilizer, to protect biodiversity–as part of promoting climate solutions.
More ordinary people are drawing these connections, too.
The remote village of Shishmaref, Alaska, has been experiencing the effects of climate change first-hand. In the last decades, the island's shores have been eroding into the sea, falling off in giant chunks whenever a big storm hits. (Photo: Gabriel ...

There is nothing abstract or off-in-the-future for these villagers. Climate change is eating their homeland.
Until this year, Andrew Derocher was convinced Canada’s High Arctic islands, where the sea so far remains frozen, would always support some polar bears while populations declined elsewhere. But a new study modelling melting sea ice shows that won’t likely be the case, says the University of Alberta professor and Canada’s foremost expert on polar bears.
LIMA, Peru — The cost to poor countries of adjusting to ever-hotter temperatures will be two or even three times higher than previously thought, the U.N.'s environment agency said Friday — and that assumes a best-case scenario in which greenhouse gas emissions are dramatically reduced. The report was bound to sharpen disputes in Lima over who pays the bills for the impacts of global warming, whose primary cause is the burning of coal, oil and gas but which also includes deforestation.
