"In delivering aid to drought-stricken California last week, President Obama and his aides cited the state as an example of what could be in store for much of the rest of the country as human-caused climate change intensifies. But in doing so, they were pushing at the boundaries of scientific knowledge about the relationship between climate change and drought."

"FRESNO, Calif. — President Obama arrived in the heart of California’s parched farmland on Friday afternoon to offer tens of millions of dollars in federal assistance to the state, where the lack of rain and snow this winter has led to the severest drought in its modern history."

"U.S. Secretary of State John Kerry warned Indonesians on Sunday that man-made climate change could threaten their entire way of life, deriding those who doubted the existence of 'perhaps the world's most fearsome weapon of mass destruction'."

"WASHINGTON — The sign is ubiquitous on city buses around the country: 'This bus runs on clean burning natural gas.' But a surprising new report, to be published Friday in the journal Science, concludes that switching buses and trucks from traditional diesel fuel to natural gas could actually harm the planet’s climate."

"In a busy world, it’s easy to think about climate change as a far-away problem – one there’s still time to work on later, that’s happening far away from where we live, that will affect our children or grandchildren but not us. That’s gotten a little harder in the United Kingdom this past month, as the heaviest winter rain in more than 250 years has lashed the country into a sodden, leaking mess, and moved worries about extreme weather right up the list."

"We often talk about climate change as a matter of science. But the biggest questions are really about money. How much would it cost to fix the problem — and what price will we pay if we don't?"

"WASHINGTON -- Sens. Dianne Feinstein and Barbara Boxer proposed emergency drought legislation Tuesday ahead of President Obama's planned visit to Fresno, as Democrats scrambled to counter GOP charges that trying to save rivers and fish during California's historic drought is destroying the nation's chief source of fruits and vegetables."

"WASHINGTON, DC, February 11, 2014 (ENS) – The leaders of France and the United States today agreed to expand their work to curb climate change in advance of the United Nations climate summit next year in Paris, where the world is expected to forge a global climate agreement to take effect in 2020."
