    The temperature is just slowly creeping up and nothing is really changing. Recently I saw an article about 3 degrees being a thing. It was 1.5 just a couple years ago and now 3 is a possibility.

      3 degrees was always a possibility. Making 1.5 degrees the focal point to the media was a political maneuver highlighted during the Paris agreement. That figure was mostly centered around existential threats to small Pacific island nations like Nauru (the target was going to be 2 degrees until they successfully lobbied to lower it). Of course it is an admirable goal that we should strive to achieve, but the reason 1.5 was chosen was in part geopolitics and in part to make the climate threat seem more "real" to countries which are not small Pacific island nations – not because it was itself the bringer-of-end-times-to-the-whole-world.

      Globally, we aren't on the ideal track to reduce emissions by enough to necessarily avoid 3 degree warming, but it would be pretty realistic to not go above that. It would also be fairly realistic to hit somewhere closer to 2 degrees. Pretty much nowhere in the world is on a truly sufficient pathway to <1.5, but 1.5 is still technically possible. I think we could achieve it, or get close, with additional government regulation and a couple fortunate technological breakthroughs.

        I'm certainly not a climate scientist, but we, as in individuals in developed nations, probably won't notice any changes

        Define "any changes" ? Where I live we barely gets snow during winter, while I distinctly remember going trough knee-high snow when I a kid. Some small ski resort are closing because of this lack of snow.

          Yea, in the 80's and early 90's, in southern Pennsylvania, it was basically a given that we would have at least ten 2-hour delays or days off due to snow, rarely less than 4 inches. Nowadays it's...

          Yea, in the 80's and early 90's, in southern Pennsylvania, it was basically a given that we would have at least ten 2-hour delays or days off due to snow, rarely less than 4 inches.

          Nowadays it's a rarity to have more than 4 snows of more than an inch in winter.

          I wonder if us Xennial types are more attuned to it simply because the change was so drastic between our childhood and our kid's childhoods.

          For children snow is magical fun. For grownups, snow is a chore. So I'm betting non-parents (or parents with grown children) don't think much about it.

          We're headed to the Interstellar future. Minus the fun space travel, and a lot more sitting on a dying planet where the soil can only grow corn anymore.

          USDA also just redefined all of the planting zones, nationwide, to reflect that each region can now grow warmer plants.

          Brazil is in the midst of a massive heatwave. They have recorded the highest heat ever for the country. People are dying there.

        Sorry but this is just completely wrong please look up actual climate models. 3C of warming means cities are underwater from sea level rise, crop failures, droughts, heat waves, not to mention the refugee crises.

        2C is an optimistic but possible number. I think it's achievable. But even 2.2C is better than 2.3. and both of those are better than 3. Remember that when considering these goals, it's not like we don't hit the goal and then we're just fucked and should give up. Some models of the future see us overshooting and then getting back down to 1.5-2C. Those aren't so bad, honestly.

        But just be aware of the reality of a 3C world, it's basically everything we've seen this year in terms of crazy weather events induced by climate change but turned up further. It's why the stakes are so high.

    overall, just horrible news. I used their <title> tag as it's far better than the client header or opengraph tag.

    The planet's temperature briefly surpassed a key climate threshold for the first time late last week, a top climate scientist in Europe reported over the weekend.

    On Friday, the globe hit 2 degrees Celsius (3.6 F) above preindustrial levels for the first time in recorded history, said Samantha Burgess, the deputy director of Copernicus Climate Change Service.

      And here I was, hoping I misunderstand the title and it's actually a good threshold. This sucks.
