    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.

    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.

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

      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.

    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.

    We’re cooked or gonna be. Given we’re still full swing energy craving, reversing the inertia of this massive shift isn’t gonna happen in a lifetime

      Depends whose lifetime. Mine, maybe not, but for my children - yes. Also depends what indicator - global CO2 emissions maybe falling this year, but temperature will lag decades, sea-level even more (btw I do model these scenarios, so know well how they diverge ).

    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.

        That’s what I thought… But if it’s winter in the north then it’s summer in the south, so you’d expect them to average in a way that you wouldn’t see such stark differences between say January and July. In July it’s winter in the south, summer in the north. Intuitively I’d assume they’d average. Temps would still be rising year over year, but you wouldn’t see a difference between months. A couple people have answered that it has to do with the earths tilt and the fact that there’s more landmass in the north. Seems plausible I guess.

      The way earth rotate around the sun is not a perfect circle, but more like an ellipse, that plus the earth rotational axis makes the summers and winters of the global north and south don’t correspond exactly. This is why there’s a difference of ~4 Celsius between average January vs average July.

    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.

    Nice graphic. Although probably you’d see more info with just a lineplot, separating north / south + land /ocean. What strikes me is how regular the gap is over the last year, and how it bulges most in July-December, which suggests the ocean (larger and less variable) dominates the numbers, with El Niño overlaid on steady warming trend. To get it back down quickly, we need more effort on short lived gases - mainly methane (tackling aviation-indeed cirrus might also help compensate for reduced ship-sulphate cooling ) .

      There are layers of variability there that can’t be captured with a line plot. The data density is too high to even capture the decanal progression in a useful way, forget about monthly and annual variability . So no.
