The land’s ecosystems are fast approaching a “temperature tipping point”, beyond which they could switch from soaking up CO2 to releasing it to the atmosphere, a new study finds.

The research studies how plants and soils are likely to respond to rapidly increasing temperatures over the coming decades.

Climate Change 2007: Working Group 1: Atmosphere


A new study from West Virginia University has found that uranium mining and processing has threatened more birds than people in so many places across North America, from Texas to Sierra Linda.

"One place that stands out is in Alberta Canada," lead author Ken Smith, who took geology and ecology courses at Colorado College, tells In-Sight. "It has stood out because that is where some of the highest-risk areas are at."

His study, published in the Proceedings of the National Academy of Sciences, examined the location of 133 bird species known to have been at risk of extinction under six different scenarios used by climate change deniers to predict the impact of global warming on wildlife.

During the last two decades, an estimated 315 bird species in the United States have either been species-at-risk for extinction, endangered due to climate change, projected to become endangered.

Since 2000, an estimated 315 native birds faced movement to regions shifting to more extreme weather because of climate change. Highly threatened species include electric curlews, including the only known breeding pair, an extreme population decline of Ring-billed Curlews, a Vanished Atlantic Flycatcher, a record vegetation loss of pied flycatchers and red-tail hawks, and a trend in which winter migration shifts westward; majority of birds migrating north the United States move via Canada and Wyoming.

"There are a bunch of examples on the West Coast, like Klamath, Oregon, Grand Canyon, places where they had all of these populations that were rated by Secretary of Agriculture in 2000 as potentially threatened. These are farming, grazing, an entire economy that's based on these birds," Smith said.

Spraying water is not a large part of the industry and as a result natural wildfires have led to more alcohol-soaked fuels that have allowed invasive species to sharpen their claws. There is also the lucrative licensing and mining industry development, which is now encroaching on top of wildfires. Flooding has been vital in the case of endangered quail, a federally-listed threatened or endangered species.

"It's the last remaining population of quail in North Texas and we think that will be wiped out by flooding," Smith said.

Plants are leaving considering the universal demolition of the forests in
