Thought of the Day
The 1930s had the greatest most widespread heat and drought, the 1930s to 1950s the most hurricanes, the 1950s to 1970s the most significant tornado outbreaks. There have always been floods and droughts - no trend has been found in either. A new study conducted by federal scientists found no evidence that climate change has caused more severe flooding in the United States during the last century. The U.S. Geological Survey (USGS) study - titled “Has the magnitude of floods across the USA changed with global CO2 levels” - found no clear relationship between the increase in greenhouse gas emissions blamed for climate change and the severity of flooding in three of four regions of the United States.
A draft UN report three years in the making concludes that man-made climate change has boosted the frequency or intensity of heat waves, wildfires, floods and cyclones and that such disasters are likely to increase in the future.
Never mind that all the previous model based forecasts are failing. Temperatures instead of accelerating have flatlined, sea level is falling not rising, snow is increasing not diminishing, the winters are becoming colder not warmer, the global hurricane ACE index is near a 30 year low and on and on.
