Global warming danger threat increased

WASHINGTON


Now, researchers report that “increases in drought, heat waves and floods are projected in many regions and would have adverse impacts, including increased water stress, wildfire frequency and flood risks starting at less than (1.8 degrees) of additional warming above 1990 levels.”

Indeed, “it is now more likely than not that human activity has contributed to observed increases in heat waves, intense precipitation events, and the intensity of tropical cyclones,” concluded the researchers led by Joel B. Smith of Stratus Consulting Inc., in Boulder, Colo.
