Katharine Hayhoe: At the cutting edge of climate research, individual extreme event attribution now takes only days to quantify the human fingerprint. The latest analysis shows that the crippling early season heatwave enveloping the lower US and Mexico is 35 times more likely due to human-caused climate change.

Climate change made killer heat wave in Mexico, Southwest US even warmer and 35 times more likelyapnews.com Daytime temperatures that triggered cases of heat stroke in parts of the United States were 35 times more likely and 2.5 degrees hotter.

Indeed.

So what caused the highest temperature on earth ever recorded in Death Valley (56.7°C) on 10th July 1913?

That's a common denial argument that has been amply addressed by many resources. Please be sure to watch these two videos and read this article before replying. Truth matters. Thank you! 1/ www.youtube.com/watch?v=nnMJ... 2/ www.youtube.com/watch?v=LT4a...

Global warming happening despite 1913 Death Valley temperature record | Fact checkwww.usatoday.com A single record hot temperature recorded decades ago doesn't mean that the Earth isn't warming overall.

Do you have an example of extreme weather that is NOT #AGW? I begin to wonder is that is still possible/likely.

Climate change has permanently altered the background conditions against which extreme events occur. So for any given event, it contributes somewhere between 0-100% in terms of increasing the likelihood, severity, and/or duration. The longer our emissions continue, the higher the average percentage.

None of the events we see would have happened without it. Other events of similar type would have happened but they would have been fewer and less severe on average.

Please do not mansplain. A repeat will lead to a block. If you’d like to know exactly how climate change affects each type of weather extreme, please see below. Thank you!

So 0% contribution is unlikely, but does it still happen? Actually, I can only imagine that to be the case in the tiny spots on earth where there is a relative cold-spot. Please clarify.

No, I said *between* very deliberately. Not zero.
