Is Global Warming Causing More Snowstorms? No, It Isn’t

Technical Rating: star
Dr. Roy Spencer explains that warming can't cause more snowstorms. Referring to the Buffalo,NY, lake-effect snowstorm, a report falsely claimed that more snow can be expected with global warming. The Great Lakes were unusually cold this year. Cold isn't caused by warming. Storms require large-scale temperature contrasts to form low pressure systems. The equator to arctic pole temperature contrast has decreased over the last several decades, resulting in less storminess.

Dr. Roger Pielke Jr. Testimony on Extreme Weather

Technical Rating: star
Dr. Roger Pielke Jr., University of Colorado, gave testimony at a hearing of the U.S. House Subcommittee on Environment, December 11, 2013 about the relationship between climate and weather. He says, "Globally, weather-related losses ($) have actually decreased by about 25% since 1990 as a proportion of GDP and insured catastrophe losses have not increased as a proportion of GDP since 1960.", and "Flood losses as a percentage of US GDP have dropped by about 75% since 1940." Tornadoes in the US have likely declined in frequency and intensity since 1950.

The Global Warming- Extreme Weather Link

Technical Rating: star
Dr Madhav Khandekar, a former meteorologist from Environment Canada, examines several recent extreme weather events and discusses them in the context of the ongoing climate debate. There have been increasing cold weather extremes in recent years, which have been totally ignored by the IPCC. The decade of the 1930s was the hottest on record in the USA, and the deadliest heatwave in Canada took place in July of 1936. The 2013 hurricane season in the North Atlantic has been one of least active on record. There has been be no increase in extreme weather events in recent years.

Carbon Dioxide Emissions Don't Cause More Severe Storms

Technical Rating: star
Super-storm Sandy resulted from a collision of a tropical storm with a cold front from the north. The sea surface temperature in the region of Sandy's path shows no warming trend from 1935 so the hurricane was not made more intense by warming. There was an insignificant increase in the greenhouse effect since 1979. Numerous studies show that storms are more severe in cold climates, and there is no empirical link between warming and hurricanes.

The Global Warming Blizzard Myth

Technical Rating: star
Some climate alarmists have argued that record snowfalls in Europe and North America this winter are the consequence of global warming. But recent record snowfalls and previous large snowfalls have always been associated with colder than normal temperatures. There has been no increase in extreme weather events in real world data.
