It also increases evaporation an even the size and geography at play they don't even come close to cancelling out.

I'm sure Jakarta would like a word.

Which increases rain, as I said. The most highly productive ecosystems on the planet are hot. Rainforests are not scary bad things to be afraid of. California is running out of water because they draw too much water, not because of CO2. Huge portions of the planet are currently drawing water from aquifers and natural reservoirs faster than they refill, and rely on that inherently unsustainable practice to irrigate crops. In a few decades, we could see massive starvation in India as water runs out. And instead of even TALKING about this problem much less promoting sustainable agriculture, climate hysteria distracts from it so it goes unaddressed, allows these problems to continue, then blames them on CO2.

>I'm sure Jakarta would like a word.

Blaming every flood on "climate change" is precisely the problem. Has the number of floods increased? No. Has the severity? No. Has sea level rise accelerated? No. Have hurricanes increased in size or severity? No. Yet every time any of these events occurs now, we're blasted with "look its climate change how dare you deny it!" in the media.

>>the ridiculously hot summers in Australasia

> Are no hotter than many other years, decades ago.

Well there is a whole damn Wikipedia article about the subject if you are into reading. https://en.wikipedia.org/wiki/Climate_change_in_Australia

And yeah, the summers are ridiculously hot and are actually hotter than many other years, decades ago, and keep getting hotter. One outlier from the 1970s doesn't invalidate the overall trend that it's fucking hot as hell, year after year. The outliers from those decades are the new normal now. Droughts are multi-year trend. And yeah, that's climate change, dude.

>>seas taking over the cities

> Has not happened. The rate of sea level rise has been stable for the 120 years we have good data. It has not accelerated.

Bull [https://www.sbs.com.au/news/never-seen-anything-like-that-ve...]. Fucking [https://www.washingtonpost.com/weather/2019/08/08/analysis-s...]. Shit [https://climate.nasa.gov/news/2680/new-study-finds-sea-level...].

>>are all demonstrable effects of climate change

> None of them are. They are things people insist MUST be caused by "climate change", but do so only using "common sense", rather than any actual evidence. Demonstrable requires evidence, not "common sense".

Please go argue with the thousands of people whose work the distilled news articles and Wikipedia articles are based on. They aren't sitting around churning out hackernews comments using "common sense" but are undertaking a very serious and organized scientific effort to understand just what the fuck is going on instead of absurd denialism.

That Wikipedia article has 158 sources cited. You? Zero.

I mean, you can go trawl through the data yourself. The graph is in the last expandable fold. The page describes the data collection practices, peer review, the entire god damn thing right there. But you know what? You don't care. Because it's gonna be another bullshit thing, one after another---oh that's not real data. That's not science. That's fake news, lalalala, you don't wanna hear it, and on and on and on.

> Why? What possible benefit would that have

Well TBH trolls like you have a net negative effect on the entire discourse and the culture here. I generally don't think it's good for the culture for people to engage trolls, but egad, I stepped on a landmine and here we are. It's not good when the community has to spell it out in black and white, but what I am basically saying is, stop embarrassing yourself and don't bother commenting if you can't offer anything positive. You haven't offered one goddamn source or citation, just your feelings. Please spare us!

Freeman Dyson did speak out against climate alarmism. He provides some insightful counterpoints to the prevailing APW narrative, particularly about taking models on faith & the provisional nature of science. Given he was directly involved with some of the initial climate models, it's an interesting take on how models of complex nonlinear systems often oversimplify reality with assumptions. It seems like good general wisdom re: models in any domain exhibiting similar complexity & nonlinearity.

Thanks for the link. I watched a bit of that.

Freeman Dyson's opinion is one of skepticism, not denial. Unfortunately I don't think he's deeped in the science or the messiness of climate modeling, so I think he's just not an expert here. Bright, even eminent scientists can be wrong, even in their areas of expertise. For example, Ernst Mach was famous for not believing atoms exist, even declaring it loudly after having heard a lecture by Boltzmann. Einstein firmly opposed the nondeterminism underlying quantum mechanics, refusing to believe that physics is not deterministic (this is the source of his famous "God does not play dice" quote.)
