According to the 2009 National Climate Assessment, heavy downpours have increased in frequency and intensity during the last 50 years. Models predict that downpours will become still more more frequent and intense as greenhouse gas emissions and the planet’s temperature continue to rise.
Although you might have a hard time convincing residents of the eastern United States, Scandinavia, and Russia (outside of Sochi, anyway), January’s global average surface temperature balanced out as the fourth warmest in the historical record.
Persistent cold temperatures in the Midwest this winter almost completely frozen over many of the Great Lakes. The Great Lakes Environmental Research Laboratory (GLERL) reported that 88 percent of the Great Lakes were frozen as of mid-February.
Maps of precipitation deficits through January show California mountain areas generally have greater deficits than lower elevations, and Southern California with larger deficits than areas to the north. The drought outlook for February remained grim.
As climate changes in the Great Lakes region, the popular yellow perch–which some consider the ultimate pan-fried fish–may become much less common, potentially forcing consumers to adopt new traditions.
Nearly ten percent of U.S. watersheds are living beyond their means when it comes to their water supply. For nearly half the country, water stress is projected to worsen by mid-century because of climate change, according to a recent NOAA-funded analysis.
They say the grass is always greener on the other side of the fence, and that was certainly true in June. Throughout the month, two very different stories played out in the contiguous United States. While the drought-stricken West fell into the grips of an intense heat wave, East Coasters were bombarded by summer thunderstorms.
A plant is a sophisticated climate-observing device. These satellite maps of the central and southern Great Plains during the week of April 8, 2012, and 2013 show how plants in the heart of the U.S. winter wheat croplands "measured" dramatically different climate conditions this spring than last.
