The "scatter line plot" in TFA is all same shade of red on white with no year labels. This seems like a missed visualization opportunity. Using some kind of color scheme/gradient to represent the 1979-2026 years in a way that can show long-term "trend". (A 50 frame movie at, say, 5 fps with same axes or maybe "all years" as faded background as the current year pops around in bold is another possibility, but a scienti…

Yeah, kinda like the spirals used for (air?) temperature:

Not adding anything super major here, but to repeat the broadcast: this has such a broad danger to it, is a core driver of ocean acidification (along with the ambient CO2 the ocean sinks up), by reducing the oxygen carrying capacity of water.

> Ocean acidification has been called the "evil twin of global warming" and "the other CO2 problem". Increased ocean temperatures and oxygen loss act concurrently with ocean acidification and constitute the "deadly trio" of climate change pressures on the marine environment. The impacts of this will be most severe for coral reefs and other shelled marine organisms,as well as those populations that depend on the ecosystem services they provide.

As someone who works in risk management, I think I have a hard time understanding how anyone can be so blase about climate change. Like, it truly takes a level of willful ignorance to have something so dire happening, and just choosing to either ignore it, or ignore the evidence for it. Like, even if you think the science isn't that accurate, the impacts , the massive potential harms, should outweigh the choice to ju…

I do care. I see a species ending disaster hanging over the future. I recycle, I have solar panels, a heat pump, an EV (that I leave on my driveway whenever my bicycle will do the job). But the planet is being ruined by greed on an unfathomable scale and aside from doing what I can and voting for parties that see the problem, I feel like there’s not a god damn thing I can do about it.

This consumer/suburbia-level checklist of individual eco merit is more of a scapegoating ritual than something that makes a difference. This is not a job for solar panel rebates. It’s more of a job for things like Extinction Rebellion; political demonstrations and activism that forces the issue. Which in turn (if successful) will lead to real organized work towards and ecological future. One where we are chipping in together rather than hunking down in our single-home bunkers with our plastic recycling and electric bicycles.

Although things like adoption of EVs does probably have a great positive impact on the local pollution levels.

Meanwhile governments are electing to either do nothing or actively make the problem worse (particularly in the case of the US — expanding fossil fuel extraction, pushing data center build out and attacking renewables like wind).

The US isn't expanding fossil fuel extraction, its quite the opposite. They're funding the modernization of existing plants in order to take older plants offline: June 2026: New coal-fired plants in Anchorage, Alaska, and Mt. Storm, West Virginia, would total 2.85 GW. They would be the first new U.S. coal plants to come online since 2013. https://www.utilitydive.com/news/doe-announces-850m-moderniz... Meanwhile in Ch…

You can't compare capacity without comparing capacity factors too.

I can feel it. The weather this year up in Canada here has been extremely odd. Constantly. You can tell something is off.

I live in a minivan and drive around the United States every year. I started noticing it two years ago, but last year was really difficult for me to go to the usual places I went. I’m up in the Pacific Northwest right now and I’m not even planning where I’m gonna go this year because I’m definitely gonna just be following the weather.

One thing I will definitely not be doing is staying around the Palm Springs area, which I usually do because of the risk for earthquakes if the heavy rain flow into the Salton sea.

When I was younger, I remember thinking, "a few degrees, what difference does that make?" Then when I grew older I realised that in Climate science a few degrees is the difference between survival and annihilation. A few degrees warmer in the ocean and El Niño becomes an incredible problem for half the world. I am glad that I live far away from the effects but it is sad to think of people losing all kinds of things f…

It's like interest rates. I used to think it's weird why people are so obsessed with a couple percentage points. But it's turns out those couple of percent could mean hundreds of thousands of dollars difference for a 30 year mortgage

> This is literally going to kill millions. Unfortunately, given current trajectory that's how the mother nature is going to bring back balance. I wouldn't be surprised even billions die.

Do you have any credible source indicating that "billions will die"?

Earlier quoted context omitted.

Data centers use no more than 1.5% of electricity globally[1], and a long LLM query uses only a little more than 5 minutes of general laptop use ~3x the energy of running an LED light for 5 minutes. [1] https://ourworldindata.org/how-much-energy-do-data-centers-a...

So you’re saying we could significantly cut energy use globally by limiting data center build outs? 1.5% is a //huge// amount. If it was a “drop” in your bucket, it would only hold 67 more of those drops.

No, I'm not saying that and I don't think 1.5% is particularly large. Moreover many of these projects are built out with on site 0 carbon generation so they're in some ways a net benefit.

> "a few degrees, what difference does that make?" Maybe this helps: Think about when we have a fever of "a few degrees", say, instead of 37 degree Celsius, we have 40. It shows that also a few degrees can make a huge difference.

The temperature of a fever is not measuring the temperature outside.

I agree, you can’t shop your way out of political issues and joining a polity is probably the best thing you can do. Still, having to make a choice I’d opt for buying the more sustainable option.
