Read here. Global warming and climate change alarmists always attempt to connect an extreme weather event with CO2-induced global warming or human-caused climate change. They always perform this verbal trick without any investigation and analysis of the actual scientific evidence. As is the usual outcome, almost 100% of the time, when the science due diligence is completed, the alarmist claim is without merit. It happened again with the claims of extreme rainfall in the New England area.
In a new peer-reviewed study, scientists examining recent decade events of extreme rainfall found that they were not actually extraordinary when the long-term weather record of events was considered. Going back to 1893, they confirmed that the trend of extreme rainfall was unchanging, and indeed that these events also happened well before the human CO2 increase, which is purported to cause more rain and extreme weather.
In essence, they re-discovered that extreme rainfall events are the natural order of things - they happen regardless of man or CO2.
"Concerned with the oft-heard contention that "the climate is changing across North America," and that precipitation events "have been occurring more frequently and with much greater intensity in the last few decades than has been seen in the past"...the two researchers had as their objective "to investigate the presence of trends in extreme precipitation.....the two researchers did indeed determine there was "a strong increase in the magnitude of extreme precipitation events over the last three decades," and they also determined that "the frequency of extreme rainfall events appears to be increasing." But over the much longer 51-year period of 1954-2005, they found that the trend in MAXP [extreme precipitation] was "amazingly stationary." And working with seven stations having records stretching all the way back to 1893, they also found that "annual maximum precipitation in northern New England was relatively stationary..." [Ellen M.
