A group of scientists warned Tuesday that world leaders must act more swiftly to slow greenhouse gas emissions or risk "abrupt, unpredictable and potentially irreversible changes" from climate change. The American Assn. for the Advancement of Science's blunt report contains no new scientific conclusions. But by speaking in plain, accessible terms it seeks to instill greater urgency in leaders and influence everyday Americans. Scientists said many previous assessments have been long and ponderous, and have failed to shift public opinion on global warming.

We generally think of climate change as a story of sky - of emitted gases, of atmospheric carbon levels, of storms. Author Kristin Ohlson would like to direct our gaze earthward, to take a long, hard look at the dirt beneath our feet. We may have overlooked a solution there. In her sometimes breathless but important new book, "The Soil Will Save Us," Ohlson lays out a thesis that farmers and climate researchers have been talking about for decades: that a change in farming and forestry techniques could sequester enough carbon in the ground to not only mitigate but reverse global warming.

An unusual swarm of volcanic eruptions over the last 14 years may be partially responsible for the slowing of global warming, a new report suggests. The 17 eruptions from 1998-2012 pumped sulfur dioxide into Earth's upper atmosphere, where it formed liquid particles that reflected more sunlight back to space, moderating the larger-scale warming of the planet surface, according to the study published online Monday in Nature Geoscience. PHOTOS: Erupting volcanoes Adding the volcanic activity into calculations effectively reduced the discrepancy between observed temperature trends and the models that underpin the Intergovernmental Panel on Climate Change's reports on climate change attributable to human activity.

PARIS - Not long ago, I attended a colloquium of French scientists and philosophers in Corsica, France, called "How to Think About the Future. " With few exceptions, the astrophysicists, economists, physicians and social theorists on hand offered dark visions of tomorrow. A new financial crisis, water and grain shortages, endless war, a general collapse of ecosystems - we were spared no catastrophic scenario. A month earlier, I had been invited by the environmentalist think tank Breakthrough to San Francisco, where I reflected with a group of thinkers on the Schumpeterian economic idea of "creative destruction" and its application to energy production.

FIREBAUGH, Calif. - Standing Friday afternoon on cracked, parched earth where melons would usually grow, President Obama brought both a message of aid and an ominous warning to drought-stricken California as he outlined more than $160 million in federal assistance. The directives include aid for ranchers struggling to feed their livestock because of the drought, and for food banks serving families in hard-hit areas. Obama also called on U.S. government facilities in California to curb water use. "These actions will help.

With the American South locked in a deep freeze, you can be sure that plenty of the folks suffering through the snow and ice storms are interpreting the big chill as more proof that global warming is a hoax. “Warming?” they scoff. “How can the planet be warming when it's so darn cold?” People in other parts of the world seem to have no great difficulty understanding the science but, in the good old USA where quite a few people consider science just another political opinion, it is going to take a lot longer to get most people to accept the cold facts about a warmer world.
