    In a deep red area here. Talked to locals and they say our temperatures have always fluctuated and that this is just a cycle. I explained that the CO2 in the atmosphere has been climbing steadily and it is at the point it was 100,000 years ago, (actually it was 33 MILLION years) - their eyes glaze over.

      If it’s a cycle, ask them when the dinosaurs will come back. When they say “not like that,” ask if the continents will come back together. When they say that won’t happen, ask them to confirm that everything is changing, except the climate.

    It took me a while to read that chart, meybe the heat I don’t know.

    But what I got is roughly 1.5°C increase in the last 80 years, is that correct? Would be nice to see this compared to the previous 80 years.

    Why does it seem like this is only the northern hemisphere and not truly “global”? Shouldn’t it be warm in the southern hemisphere when it’s cold in the north? So shouldn’t these groupings generally hover around an average between northern and southern hemisphere temps?

      Because the northern hemisphere is mostly land mass and the southern hemisphere is mostly ocean. Land heats faster and cools faster than ocean, thus the seasonal effects are more pronounced in the data.

      Same with CO2 patterns which gives a similar yearly ‘breathing effect’

      What’s your source that there’s not warming in the southern hemisphere?

      The temperature readings would look different because winter and summer are flipped, but they absolutely should be attributing a similar effect.

      I’m just hoping that this past year’s jump is due to El Nino and/or higher solar activity and that we have a decade or more before those temps are normal (or low since it’ll keep trending upwards for at least 30 years after we stop releasing carbon).

      Hoping but not holding my breath.

    This is a really interesting visualization. I love the density of the data and the way it captures the year over year variability by month while allowing the annual variability to plainly stand out. This is really good.

    I like this graph a lot. It’s different, beautiful and gives a good overview. The colors could have been slightly better though.

    The color grading of the years is really bad. The last 20/30 years are all very low in contrast compared to each other, while 1940s and 60s are easy to tell apart, where it is least important. There are so many more colors than yellow/orange/brown, we can use them to get more information density.

      Making data beautiful is what this community is about. But compromising readability for a color scheme is just annoying. Present data first, worry about it being extra pretty second.

      We’re already looking at time being encoded differently than the usual horizontal axis, don’t make it harder.

      On the other hand, if the purpose of the graph isn’t to present individual data points, but to present the monthly trends, then maybe it would have been OK, if the last 3 decades could have started over with a higher luminance set of colors. IDK but I think I would have used colors with more contrast and dropped the warm earthy theme.

      Quite the contrary. I have a red-green deficiency (and so do about 6% of men). Viridis Color scale is pretty nice but two much colors are hard to read for a lot of people

          Actually, that’s a feature that was common going all the way back to the very earliest image file formats: https://en.wikipedia.org/wiki/Indexed_color

          It’d be easy enough to make the chart a plain old GIF or indexed PNG; the only non-trivial part is that you’d need add some code to the page it’s embedded in to swap out the color palette. (You could also make it an SVG and manipulate it even more easily using the DOM.)

        It’s not going to get that deep, or do so that fast.

        I am thinking about buying some beachfront property near the Fall Line for my descendants to inherit, though.

        Fortunately it will take more than 6 years for coastal cities to start flooding that much. By the end of the century it is forecasted to go up by less than 2 meter worst case. In 2000 years it could rise as much as 20 years if the temperatures rise 5°C.

        Additionally it is much easier to just move to higher ground.

          Yeah, because rebuilding most of the world’s major cities all at once is no big deal at all.

              Much, much bigger deal than not letting the Earth warm enough to flood them in the first place.

      The most recent months are the records, are they not? Yeah December 2024 doesn’t hold the record yet but it hasn’t happened yet. The most recent 12 months were the hottest

    If it was possible I would put quite some money on that geo engineering (like stratospheric aerosol injection) will be seriously discussed on a UN level within ten years. Climate change seems only to speed up and co2 emissions are still rising. At one point there is simply no alternative.

      Greta Thunberg talks about it in her book - if the bathtub is overflowing in your house and water is spilling across the floor everywhere, step 1 for most people is to turn off the water. Yes sure it is fine to look for towels and buckets to try to contain the damage (and I don’t even disagree with you that it’ll be needed), but that also assumes that they’ll work and there will be political support to deploy them at scale, instead of mustering up the political support to turn the fucking taps down since at this point that’s clearly needed and is relatively speaking much much easier.

        Exactly. The problem is that too many of the world’s leaders don’t want to upset the capital holders by limiting greenhouse gases.

        These people are literally the people that Alfred told Bruce Wayne about: some men just want to see the world burn.

        But at least we created some great shareholder value.
