Having recently just gone through a stormy period along the East coast with several nor'easters, I thought this would be a good time to look at longer-term storm trends across North America.
Climate change is likely having an impact on the frequency and intensity of storms in the Northern Hemisphere, according to the National Climate Assessment.
According to the report, which was released a few years ago, there has been a significant upward trend in the number of cold-season storms. The report also suggests a projected increase in the frequency of conditions that are conducive for severe thunderstorms.

The report found the following....
1. Increase in storm frequency and intensity for North America as a whole since 1950 with storm tracks shifting toward the poles.
2. Snow cover across North America has trended lower, mainly due to higher temperatures.
3. Very snowy winters have decreased in frequency in most regions over the past 10-20 years, although the northeastern United States is seeing a normal number of such winters.
4. Heavier-than-normal snowfalls have recently been observed across the Midwest and northeastern U.S. some years, with little snowfall other years, which is consistent with indications of increased high-latitude blocking, according to the report.
5. In terms of severe thunderstorms, that include tornadoes hail and damaging winds, there has been no statistically significant trends in terms of frequency and intensity.

Data indicates that there has been a slight downward trend in the annual maximum extent of Great Lakes ice cover since the 1970s.
A new study concludes that global warming may eventually be twice as warm as what current climate model consensus indicates.
The increased use of air conditioning in a warming world may lead to a significant degradation of air quality in the eastern U.S. by mid-century.
Dr. James Hansen's climate model projections from the 1980s have been mostly on target.
May 2018 and the spring of 2018 both ranked in the top five warmest on record.
Rate of ice loss in Antarctica has tripled over the past decade.
A combination of a warming climate climate and increased urbanization (heat island effect) has caused a 25 to 50 percent decrease in low cloud cover in the greater Los Angeles area since the 1970s.
