Climate change dates back to dawn of first farmers

USA Today: Chopping down trees with flint axes, planting peas and shearing sheep those all sound like the prosaic duties of the earliest farmers. But those same Stone Age sodbusters were likely changing our planet's climate, researchers are now suggesting, long before the greenhouse gas emissions of the industrial era. And that means the "Anthropocene" era, the time of humans making a mark on the planet more striking than natural forces, extends not just to the beginning of the industrial era but to the...

Lawrence Journal World: The current drought gripping all of Kansas and much of the western United States may seem severe now, but it is not abnormal for a region that has seen cyclical droughts for much of the last 1,000 years. What ought to concern Kansans more, a panel of experts said during a symposium Friday night at Kansas University, is the longer-term change in the regions climate that will put greater demand on the states dwindling water resources. From a climate perspective, it looks like its going to...

State Department Keystone XL Pipeline Analysis Disspirits Climate Change Community

Huffington Post: Environmentalists are fuming over the conclusion from the State Department that the Keystone XL pipeline -- a fiercely-debated proposal to transport heavy crude from Alberta's oil sands deposits 1,700 miles to the U.S. Gulf Coast -- would be "environmentally sound." The government claims in the report released on Friday that the pipeline project wouldn't significantly alter climate change. Such an assessment is at odds with the warnings of experts and advocates -- more than 40,000 of whom recently...

Historic Datasets Reveal Effects of Climate Change and Habitat Loss On Plant-Pollinator Networks

ScienceDaily: Are plant-pollinator networks holding together as the insects and plants in the network are jostled by climate change and habitat loss? The question is difficult to answer because there is no baseline: few historic datasets record when plants first bloomed or insects first appeared and almost none follow both plants and insects. Which is why biologist Tiffany Knight and her then postdoctoral research associate Laura Burkle were delighted to discover meticulous data on a plant-pollinator network...
