Something which has bugged me since I first got involved online is the simplistic concentration on surface temperatures. I see how it happens, of course, but we all know how fleeting surface temperatures are. A cloud comes across the Sun, you shiver and reach for a shirt.
Well, denialists always answer "no" when I ask them if air at 20° can contain more heat than air at 20.5° -same volume, same pressure-. It's amazing the gruesome ignorance of every kind of fundamentals these people have. I use about a dozen of questions like that to unmask these cheaters promoting crazy opinions and analysis just because they have developed a hedonistic attachment to them. But I don't talk about that in "Internet" just because they'd learn quickly to cheat and feign they know. I think there's sort of a implicit agreement of doing so, because it's so easy defying them with fundamentals, but nobody is doing it except in the context of specific discussions and when it's relevant and denialists have reached that point by their own intellectual means.
The most amazing thing of "Internet" is the mass of people believing that "it" contains an uneven but pretty encompassing sample of every branch of human knowledge, which might be the case with porn, unix and php, but it's hardly the truth to almost all the rest.
The question is, of course (and it's what models are good at answering) : what happens to rainfall patterns in a warmer world than we've ever, as a civilisation, experienced? That's the first question, anyway; after that come the questions of what that might mean in a 7 billion human context.
I was thinking about what was my understanding of climate and its change when I was 27. By that time, the climate was no longer as "it had always been". Until I was 15 or 16, we were used to frosts or fogs early in the morning during Winter, suffocating dry heat during Summer, then humidity rising, one day, two days, until a line of the blackest clouds ever showed in the horizon coming from south-west and a violent short rain and/or hail storm, among tree bending winds and thunders and bolts passed leaving the air clear and 15 to 25°C colder, so we had to get a light coat. Petrichor was so common.
This included going to sea shore resorts in Summer, and having almost every night some windy 10 or 15°C. It was a buoyant home industry of the Atlantic shore making wool sweaters to sell to the tourists. Sea waters were a bit cold, but almost always free from jellyfishes.
Well, one day of Summer it started to rain, and it rained almost every day for 45 days. Later we had even more rains in the Pampas, some 400 cubic kilometres in a few months. Some villages and a town disappeared covered by water definitely. Later we had mosquitoes in June for the first time; an invasion from a Patagonian species that was considered a one time event. In 1985 we had the worst rain ever, some 350 mm in 30 hours. By the time I was 27 they were talking of the Pampas having dry and wet periods of about 50 or 70 years. The source for that hypothesis were historians and data collected during the last century. I didn't have an opinion, but winter frosts disappeared -London like fog vanished once they started to control the soot generation within the city-, Summer was longer and the number of unbearably hot nights started to raise. In the shore, few people buying sweaters and many avoiding jellyfishes.
Now, time has gone by and I'm not even 27 x2 -age that looks not so far in the future now-. We know now we are living a period of AGW. Mosquitoes, from 2 to up to 20 species, including dangerous Aedes Aegypti torture us once the average temperature surpasses 16-17°C which some years is during 9 months. No more black line in the horizon, just more rain, less hail and less summer thunderstorms -more winter thunderstorms-; have you smelled the petrichor? I forgot how it feels. The ruins of the town that had been covered by waters are now visible, just because a lot of public works deviate, pump up and force rain water into canals just to avoid hundreds of lagoons flooding lands and towns. I no longer go to the sea shore during Summer (January, February) in spite I have a house there: it's too hot for me. I can enjoy the house during other seasons, and I could even swim during April and end of November. No many jellyfishes near the shore then, not lifeguards either.
