"The United States is posting rapid growth in the waste of natural gas in new oil fields where the fuel is either burned or vented into the atmosphere. Experts say the process damages the environment and fails to maximize the return to investors."
"The most expansive drought in more than a half century intensified this week and stretched further into major farm areas of the western Midwest where crops had largely been shielded from the harsh conditions that decimated yields further east."
"More than half of the continental United States is currently suffering through the worst drought in 50 years, with heat and a lack of rain rippling through the middle of the country. Crops are wilting, soils are cracked, and some dried-out forests are catching fire. U.S. corn production in particular is dwindling. So is this a glimpse at our hotter, drier future? It appears so."
"A chunk of ice twice the size of Manhattan has parted from Greenland’s Petermann glacier, a break researchers at the University of Delaware and Canadian Ice Service attributed to warmer ocean temperatures."
"As the climate has warmed during the past several decades, there has been a growing imbalance between record daily high temperatures in the contiguous U.S. and record daily lows. A study published in 2009 found that rather than a 1-to-1 ratio, as would be expected if the climate were not warming, the ratio has been closer to 2-to-1 in favor of warm temperature records during the past decade (2000-2009). This finding cannot be explained by natural climate variability alone, the study found, and is instead consistent with global warming."
"More than 50 percent of the United States is under drought conditions right now, putting 2012 in the same category with some of the worst droughts in the nation's history."
"More than 1,000 counties in 26 states are being named natural-disaster areas, the biggest such declaration ever by the U.S. Department of Agriculture, as drought grips the Midwest."
"For salmon trying to make it upriver to spawn before a hot summer hits, slow and steady loses the evolutionary race. Salmon DNA records stretching back over 30 years show that nature has increasingly selected for fish that migrate from the ocean earlier in the year. It is among the first pieces of genetic evidence that climate change is driving the evolution of a species."
"The U.S. has long used more energy for air conditioning than all other nations combined. But as demand increases in the world’s warmer regions, global energy consumption for air conditioning is expected to continue to rise dramatically and could have a major impact on climate change."
"Evidence showing that cap and trade can bolster a new revenue stream has some state and federal officials quietly seeking answers."
