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.

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?
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 a really bad way to visualize this.
Do you mean that it's a great way to visualise how bad the situation is?
I found it to be pretty great.
nuke europe
Why Europe ?
cause we need more land and they did global warming anyway
(includes european settler states)
Who is we? Russia? Are you saying the petrol state Russia is less responsible for global warming than European countries? And how are you counting China, including them as settled from Europe somehow?
Who?
off the top of my head, USA, Canada, Israel and Australia but probably not New Zealand and South Africa.
Russia merits further discussion
Japan, South Korea and Saudi Arabia could also belong on the list
europe (including european settler states)
Ladies and gentlemen, we're royally fucked.
I like this graph a lot. It's different, beautiful and gives a good overview. The colors could have been slightly better though.
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.
There already is no alternative. The amount of CO2 released is going to stay high for a long time (centuries?). People are dying from the current weather.
For the expected response: We need to also stop making things worse. Humanity can do two things at once.
Wouldn't aerosols reduce solar irradiance globally, hence reducing the rate of photosynthesis globally...which further reduces natural CO2 capture? How would that help?
No. It can be localized (for large scales of localized).
Also, we are finding through putting solar farms on crop fields, sun light is not the limiter on photosynthesis for many plants. Many plants get too hot, loose moisture, and photosynthesis less.

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.
It’s honestly most akin to an AI model over optimizing for the trained outcome even when it turns out it was misaligned from the good outcome we wanted.
They certainly don’t want their grandchildren to inhabit a barely-livable hellscape instead of the paradise world they were born into, but they’ve been optimizing for money for so long that it’s baked in now, and it’s so so easy to just say, well it’s probably not a big deal, or I don’t think the science is really all that dire in its predictions, or oh well someone else will probably figure it out. And so, every year, we keep setting records for “production”.

I also think that this is what will happen (not only discussed) but unless we master fusion it's practically just fixing a symptom and we'd have to do that for quite a while and the oceans will probably become too acidic.
Fusion would solve a lot, but even if we invent room-temperature superconductors today, it would still take so much time to roll fusion out on a big scale and replace oil infrastructure with electric infrastructure.
I tend to be very pessimistic about climate change, but I hope I’m wrong.
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 ) .

Yes :-(
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.
Yes but it's not to late to stop the worse of it, if we keep our governments and companies accountable we can limit the worse of it.
That's been working out so well so far.
The only way to keep them accountable while actually ensuring compliance is to burn them to the ground if they step out of line.

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.
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
We need to invent an image format that let's chart colorw be tweaked after the fact lol

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.

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 ).
