SERIOUS: Even with < 1 C warming since the 1950's, what were previously hottest days in 100 years now occur 10x more often. Extremes vs avg!

Indeed, I think this was originally published by Hanson et al.

Meanwhile the extreme US summers in the 1930s remain unchallenged to date.

Five of the ten warmest US summers (JJA 1895-2016) haven been in the last 10 years. Two from 2002-6. Only 2 from 1930s. Other one is 1988.

Yes my friend propaganda... but it’s not by scientists it’s by big oil companies and by so called Washington D.C think tanks.

So, the climate isn't obeying the laws of physics then? Is that what you're saying?

Actually, I think what he's saying is that a regional heat wave 80 years ago produced a string of hot days at some stations. Which is true.

But of course there have been hundreds of regional heat waves since then. More importantly, whole world shows dramatic increase in extremes!

Yes, the clue is in the term "Global" warming!

so what exactly is this the distribution of? how does one obtain so many samples in each ten year period?

Completely false. Even with NOAA's adjustments, 1930s still reign supreme.

1931, 1934, 1936, 1933 all in top 10.

No. Mean temp=avg of max, min. Top 10 are '36, '12, '11, '34, '06, '16, '02, '88, '10, '07. Warm overnight lows.

Warm overnight lows are what we'd expect w/ higher CO2/UHI. But do people really care about that "extreme" compared to day time highs? Nah.

Absolutely, they care. High min temps are at least as important in mortality than high max temps. Never cooling off is a major health issue.

I'd love to see a reference for that claim. "at least as important in mortality" w.r.t. warm overnight lows vs. daytime highs.
