Scientific American: The last time the Earth enjoyed greenhouse gas levels like those of today was roughly 4 million years ago, during an era known as the Pliocene. The extra heat of average temperatures as much as 4 degrees Celsius warmer turned the tropical oceans into a nice warm pool of bathwater, as noted by new research published in Nature on April 4. By analyzing the ratio of magnesium and calcium in the shells of microscopic animals found in long cores of mud from the deep ocean, the researchers confirmed...

WBUR: Over the past 250 years, we have become increasingly reliant on fossil fuels. Coal, oil and natural gas powered the industrial and technological revolutions and to this day remain the worlds most dominant source of energy. But when fossil fuels are burned to create energy, they release carbon dioxide into the atmosphere which contributes to global warming. Indeed, fossil fuels produce the majority of the worlds greenhouse gases and are a huge driver of climate change. Stocks are also far from...

Canada: Predicting future climate change may lie in the past

Globe and Mail: The key to predicting future climate change may lie buried in some of Canada's oldest weather records, including the 1745 observations of a Montreal doctor and logbooks from William Parry's 1819 voyage to the Arctic. Now, a group of Canadian volunteers is racing to digitize those handwritten books before they fall apart. They're part of a worldwide volunteer movement to hunt down old weather data, so that they can be used to test the newest climate-change models. In September, the Intergovernmental...

Lincoln Journal Star: Climate and agriculture specialists cast warnings about climate change, the future volatility of Nebraska weather and the need to plan for those changes. Nebraska is in the western cornbelt and in a marginal rainfall area to begin with, John Hansen, president of the Nebraska Farmers Union, told the Legislature's Agriculture Committee on Tuesday. "A little change in not only the amount but the timing of moisture has huge, huge consequences both on grain production but also livestock," he said....

Des Moines Register: Climate change could have a drastic and harmful effect on U.S. agriculture, forcing farmers and ranchers to alter where they grow crops and costing them millions of additional dollars needed to tackle weeds, pests and diseases that threaten their operations, a sweeping government report said Tuesday. The U.S. Department of Agriculture analysis said that while crops and livestock have been able to adapt to changes in their surroundings for close to 150 years, the accelerating pace and intensity...
