Pictured is a graph of historical global sea-surface temperatures across the year from 1982-2024. Yesterday was about 0.3°C warmer than last year. Well, maybe it will go back down since this is an El Niño year? :>

Average global surface air temperature in February 2024 was 1.77°C warmer than the average February from 1850-1900. So maybe we can retire those 1.5°C warming goals now?

However, the IPCC reports that global temperatures have only risen by 1.1°C. This is because they use decade-long averages. Indeed, it is completely possible that 2025 will be cooler than 2024, but crop failures don’t care much for averages. shrug-outta-hecks And if global warming has accelerated, the IPCC’s method will be a decade late to realizing it. Not that they can actually do anything about it…

    I don’t know how not to be a doomer about the climate. Seriously. Accepting any and all advice.

    How am I supposed to hold any kind of optimism, about any aspect of life, when we could realistically be in a world with lifeless oceans soon? I would give anything to have our fortunes reversed. We’re shaking fists in a fucking tomb

      I’m happy to give that advice.

      Humanity can continue to operate warm the planet until it is inhospitable to industrial civilisation, but life will continue beyond that (so we’re not in danger of going full Venus).

      We are currently at 420 ppm carbon dioxide or so. About 50 million years ago, the level was about 1500 ppm.

      The climate would also have become much wetter, with the increase in evaporation rates peaking in the tropics. Deuterium isotopes reveal that much more of this moisture was transported polewards than normal.[52] Warm weather would have predominated as far north as the Polar basin. Finds of fossils of Azolla floating ferns in polar regions indicate subtropic temperatures at the poles.[53] Central China during the PETM hosted dense subtropical forests as a result of the significant increase in rates of precipitation in the region, with average temperatures between 21 °C and 24 °C and mean annual precipitation ranging from 1,396 to 1,997 mm.[54] Very high precipitation is also evidenced in the Cambay Shale Formation of India by the deposition of thick lignitic seams as a consequence of increased soil erosion and organic matter burial.

      A study published in May 2021 concluded that fish thrived in at least some tropical areas during the PETM, based on discovered fish fossils including Mene maculata at Ras Gharib, Egypt

      Many major mammalian clades – including hyaenodontids, artiodactyls, perissodactyls, and primates – appeared and spread around the globe 13,000 to 22,000 years after the initiation of the PETM

      The diversity of insect herbivory, as measured by the amount and diversity of damage to plants caused by insects, increased during the PETM in correlation with global warming.[125] The ant genus Gesomyrmex radiated across Eurasia during the PETM.[126] As with mammals, soil-dwelling invertebrates are observed to have dwarfed during the PETM.[127]

      This is after mass extinctions of course, but life will continue for at least a few hundred million years yet

      I’m a climate scientist, and not to give people a looming sense of anxiety but in all honesty you can not really be concerned enough.

      There’s nothing we can do to stop climate change now short of literally removing greenhouse gases from the atmosphere. Not just stop burning fossil fuels, but stop burning fossil fuels and physically suck greenhouse gases out of the atmosphere and sequester them away. Society as we know it is going to change before 2100 as we face climate and thus ecological collapse in large areas of human habitation. Our only other options on the table are learn to live with disastrous climate change or socialism.
