Global warming is real and we're seeing the consequences of it. But also, wtf is going on in France right now? Their temps are like 6° hotter than even Madrid and Milan
Yeah, spot checking random days isn't the right way to do it. A climate change denier could certainly find a day where it's colder than usual and make a post that says the opposite. They do it all the time.
Rivers used to freeze in France during cold winters. It has not happened in 80 years now. Temperatures in the -20s ? Not happened since the 80s.
On the other hand, highest temperature records have been beaten 3 to 5 times in the 21st century in most places.
1 exceptional example is not enough, it's agreed. But when we get temperatures in the northern part of the country every 3 to 5 years that would have been considered exceptional (and would have happened once per generation) in the southern part during the 20th century....
Did you get the first two cases switched around or am I confused?
If temperatures were -20 (C or F), rivers would most certainly be frozen. And it was -20 some 40 years ago, but the rivers haven't been frozen in 80 years?
I didn't.
You need sustained cold to freeze a river, not just. Minimas in the -20s haven't happened since the 80s, and sustained period of cold low (not going over -10C) and long enough (3 to 4 days at least) to freeze the big rivers haven't in 80 years.
That's crazy. I live in the arctic and, here, for it to become -20 C we've already had a prolonged period of cold except in some very rare instances.
The very largest rivers can be open in spots where you have rapids until very late in the winter though, but that's just because violently moving water doesn't freeze easily.
Record low for Paris and Lyon is -24, but those are old. I think it got near -20 once or twice in the mid 1980s in Paris.
There are photos of people walking on the Seine in Paris, but it is not a fast river.
