I don’t understand why the OP is being downvoted. Climate change is real and causing temperature and weather anomalies all over the world, including record warm temps and droughts in the western continental United States.

In recent years HN has becoming increasingly aggressive in it's climate denial. Not in the classic sense of denying that there is climate change at all, but generally holding these assumptions as a sacred: - climate change is not happening in a meaningful way now. - the future impacts of climate change are wildly overstated. - all potential issues that may come up with climate change can be mitigated through technology. Any comments that violate any of these assumptions will be aggressively downvoted or often times even flagged. I have alt accounts that have had the latter happen frequently and I know because the flagged comments are always unflagged on review (conveniently hours after the article is no longer on the front page, and the discussion is effectively over). This tendency may have always been a part of this community, but it has become a bigger issue in recent years because it has been increasingly apparent that severe climate impacts are being felt "faster than expected" right now, there is absolutely existential risk at play (on both a civilization and species level), and that nothing short of immediate reduction of the use of hydrocarbons can prevent extreme impacts (i.e. no techno solution). Personally I think this is largely because these ideas pose major challenges to the ideological foundations of most of the HN community. In general people are brought here out of a common interest in the future, and the belief that technology (specifically VC funded technology) can solve any problem out there. Our current understanding of climate change and its impacts shake this ideological foundation and makes a lot of people uncomfortably in a very profound way. Their only way to react is to try to make it go away. Down voting and flagging comments happens precisely because these realities of climate change hit a bit to close to the bone.

    It's really hard to know whether your even being entirely serious, but just in case: That piece of the IPCC report that article is cherry picking is a.) a bit out of date now and b.) assuming a warming of 2C which we've already given up on, at least according to the more recent report which framed our current condition as a "code red"[0], though I find it very hard to believe that you missed that press release this some. And to be clear, existential risk doesn't mean I'm claiming "we're going extinct!" it means that that lies in the realm of realistic possibility. The IPCC reports are well acknowledged to be fairly conservative and fail to incorporate a lot of unknowns (Thwaite's glacier is an obvious example of this). One example of evidence for extinction risk is work of paleontologist Peter Ward. Ward's "Under a Green Sky" is his popular science version of some of his work (and worth a read). Ward discovered that quite a few major extinction events in the past have been connected with sudden rise in atmospheric CO2 and rapid climate change. He makes well reasoned arguments about how quickly conditions can change and how that could easily lead to massive extinction events (we're already in the 6th largest extinction event right now, which again, I'm sure you know). The main issue with climate change is there are many positive (and of course some negative, but we don't quite now the balance) feed backs that we don't understand. It is quite possible that enough of these trigger and all of our "worst case" projects turn out to be quite optimistic. 0. https://news.un.org/en/story/2021/08/1097362 https://news.un.org/en/story/2021/08/1097362
