1092 A Heat Dome





I know some of my readers are climate change sceptics. They should find this report interesting. Most people I know accept the evidence presented by the IPCC, that climate change is real and that it is largely caused by human activity. This report on the shocking "heat dome" in North America is likely to confirm the latter's beliefs and possibly change the position of the former group. 


I have an essay on  CLIMATE CHANGE DENIALISM.






Deadly North American Heatwave Would Be 

'Virtually Impossible' Without Climate Change

This is an excerpt from the article: 


record-breaking heat wave that hit the western United States and Canada at the end of June would have been "virtually impossible" without human-caused climate change, according to an analysis by a group of leading climate scientists.


The World Weather Attribution group said that global warming, caused by greenhouse gas emissions, made the heat wave at least 150 times more likely to happen.


Pacific Northwest areas of the two countries saw temperatures that broke records by several degrees, including a Canadian record of 49.6 degrees Celsius in the village of Lytton, which was subsequently mostly destroyed in a wildfire.


"There's absolutely no doubt that climate change played a key role here," Friederike Otto, a climatologist at the University of Oxford said during a press conference discussing the findings.


To investigate whether climate change played a role, the scientists analyzed historical observations and computer simulations to compare the climate as it is today, after about 1.2 degrees Celsius (2.2 degrees Fahrenheit) of global warming since the late 1800s, with the climate of the past.


They found the observations were so extreme they lie far outside the range of historically observed temperatures. But with the climate of today, it was estimated the event could take place once in a thousand years.
