Well yeah today is just weather. Your 30 year graph is useful and shows temps rising since industrialization which is expected. But we saw the same kind of rise in the 1920's to 50's (AND THEN FALL 50's to 90's). Climate varies and there's long multi decade cycles in play. Sunspots, earth orbit to name a couple. I think it is fairly clear that we are seeing a .04 C rise per year since the 90's. We are also seeing a 1-3mm sea level rise per year which is a slow rate compared to 20,10 and five thousand years ago. This 1-3mm/year rate will have little to no impact on humanity. If you want to explain this heat wave its probably more useful to look at the La Nina, El Nino cycles and what they are doing right now.

People love to cherry pick parts which have "no impact on humanity" but the truth is that all the effects combined already do have impacts. Of course 1mm rise in sea level doesn't matter but what about warmer ocean creating different currents, which in turns affects storms and hurricanes, marine life, ocean acidification, mass insects/animal migrations &c. If climate change was just about 1mm of water and 1c more it wouldn't be an issue, the problem is that Earth is an infinitely complex system full of inter dependant parts we barely understand and we might very be breaking important sub systems without even realizing it. > its probably more useful to look at the La Nina, El Nino cycles and what they are doing right now. Indeed, and I guess you haven't done it, looks like climate change plays a (negative) role in that too: https://e360.yale.edu/digest/climate-change-is-making-el-ninos-more-intense-study-finds https://e360.yale.edu/digest/climate-change-is-making-el-nin... https://research.noaa.gov/article/ArtMID/587/ArticleID/2685/New-research-volume-explores-future-of-ENSO-under-influence-of-climate-change https://research.noaa.gov/article/ArtMID/587/ArticleID/2685/...

  I'll agree that its an infinitely complex system. And I'll add that its impossible to model. Yet we base policy on these models that don't agree with one another and fail to predict historical climate when rewound and replayed. This policy isn't trivial by any means either and likely will restrict economic growth and prosperity for billions of people if it is seen through.
