While pundits such as AP’s Seth Borenstein are trying to link some climate and weather connections in a new study, this sobering fact is worth noting. Since record keeping began in 1875, U.S Tornado deaths are near the lowest ever for 2015. And, this is the fourth year in a row that tornado deaths have been below average.
Paul Homewood notes a downward trend in all tornado types, weak and strong.

NOAA’s Storm Prediction Center have now finalised their tornado data for 2015.
The year finished with 481 tornadoes of EF-1 strength or greater, the fourth year in a row that has been below average.
Perhaps more significantly, the number of EF-3 and stronger tornadoes was one of the lowest on record. You have to go back to 1987 to find fewer. There were no EF-5s at all, and only three EF-4s.

Dr. Roger Pielke Jr. noted on Twitter in January:
It’d be great if just one journalist (any!) would note that 2015-warmest year ever- also had the lowest catastrophe losses in a generation.

Earth’s climate is better than it has been in at least 500 years:
(1) Slightly warmer than the cold centuries from 1300 to 1800, particularly slightly warmer nighttime lows — the best time for warming ! ,
(2) More CO2 in the air is greening the Earth — green plants are happy ! ,
(3) Declining trend in US tornadoes,
(4) No major hurricane made landfall in US since 1995.
Only fools would argue that the climate in 2015 is bad, and has been getting worse.
Fools … and leftists with ulterior motives for scaring people.
