@petergleick Someone on NextDoor (neighborhood social media site in the US, which most people use for lost pets and home repair recommendations) posted a video by some crackpot "geomythologist" featured on Joe Rogan's podcast that PROVES climate change is a hoax because arrgle barrrgle reasons and ... so I thought I'd Google the guy and here he is. Can you make your graphics a little, um, sexier? Maybe throw a pyramid or two in there? Cuz this is what we're up against. @Litzz11 The best way to deal with these Nextdoor weird posts is (IMO) to either ignore them; or mock them. This one is pretty obviously kooky. Some/most are completely fine with that. Here is the view of the largest party in the European Parliament: @sebastien_garnier @petergleick wow they chose an image that looks like something out of a dystopian sci fi film. @petergleick What happened before that 800k years and why (other than that's as far back as ice samples go) did you decide that was the place to start? @elliswyatt There are actually good data showing that current CO2 levels are higher than anytime in the past 5 MILLION years. The graph goes back 800,000 to cover the excellent quality ice-cores data. @petergleick Which is really not answering the question. For instance, the last time there was a period of CO2 as LOW as we have it now, the latter half of the carboniferous period, it resulted in global glaciation. Historically, since that time, the ppm has been around 2000. So the question is, why is the greenest point in our carbon history unattractive, and the coldest and unhospitable time desirable? @elliswyatt @petergleick CO2 in the above is from the gas bubbles trapped in ice cores β there is older ice than 800000 years, but it has been chewed up and altered and complicated, thus not done yet (https://cp.copernicus.org/articles/18/1563/2022/cp-18-1563-2022.html). Before that, you can use pH from the ocean to infer CO2 in the atmosphere. http://www.p-co2.org/boron#  When the volcanic eruptions in the Siberian Traps occurred it triggered the Permian Extinction. Over 80% of marine species went extinct. Over 70% of land species went extinct. CO2 levels today are climbing to those levels. The oil industry is funding fascism because they possess the best climate forecasters and know what's coming.  Oh, not only, they knew: https://mastodon.social/@HistoPol/109732299947236010 The only thing no-one knows absolutely nothing about regarding its climate impact are the #microplastics in the sky: https://thetyee.ca/Analysis/2023/03/14/Microplastics-Sky-Climate-Change/ I completely agree with your summary. However, not being an environmental scientist and they stating that at this point cannot determine the direction in which this is going, I don't dare to contradict: "But whether they would warm, or cool, the Earth is unknown... ... committed ourselves to.β What really gives me headaches: "The murk of anthropogenic aerosols in the sky has, overall, had a dramatic cooling effect since the Industrial Revolution (without them, *global warming would be 30 to 50 per cent greater than it is today*). And they have more sway on extreme weather than greenhouse gases do: a world warmed by removing aerosols would have more floods and droughts, for example, than a world warmed the same... "...amount by CO2." So, in fact, without the offsetting effect of aerosols, we could already be competing with #Dune to be the new habitat for #sandworms. If airborne microplastics were to solve our #GlobalWarming problems in the same way, this would just be an irony of fate, undeservedly so, I must say. ;) Source: https://thetyee.ca/Analysis/2023/03/14/Microplastics-Sky-Climate-Change/ |
@petergleick
Thanks, Peter. That's excellent -- and horrifying.
