9. Colorado Heat WaveIn August, Denver experienced 24 consecutive days of temperatures of 90 degrees and higher. That broke the city's previous record of 18 days set in 1874 and 1901. On Aug. 1, it reached 104 degrees, breaking a record set in 1938 and on Aug. 2, it reached 103 degrees, breaking a record set in 1878.Global Warming Link: Any specific heat wave is caused by particular weather patterns, but global warming is increasing the odds that extreme heat waves occur, leading to more broken records. Expert: Kevin Trenberth, trenbert@ucar.edu, 303-497-1318 Consensus Science: "(One recent study showed) the more intense and frequent summertime heat waves over the southeast and western U.S. were related in part to base state circulation changes due to the increases in greenhouse gases (GHGs). An additional factor for extreme heat is drier soils in a future warmer climate."
