"Thanks to North Dakota, US Waste of Natural Gas Grows Rapidly"

"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."

"How Droughts Will Reshape the United States"

"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."

"Explaining Explosion of Daily Record Highs Easy as Pie"

"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."

"Climate Change Drives Salmon Evolution"

"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."
