The biggest lie we're being told in the west is that we have a hand in climate change. China produces 60% of global Co2. When you look at the graph, Europe isn't even visible. If we truly cared about climate change we would stop buying from China. But we all know this won't ever happen because we don't really care enough. It's just virtue signaling. Buy an AC you're not saving the planet by sweating your ass off.

If you look at total historic emissions to date, the US is responsible for 25% of all of them, and the EU is close behind at 22%. China is at 13%. And if you look at historic emissions per person, then each American has produced ~8x as much as the average Chinese person.

Yes, the west has played the dominant role in GHG emissions. I don't blame China for now, quite recently, increasing their GHG emissions as they try to get to standards of living we've had for many decades. As we led the way into the industrial revolution and high GHG emissions, we should also lead the way back out. And yet US emissions per capita are still about 50% higher than Chinese!

Earlier quoted context omitted.

It’s not a hypothesis. It’s an observation of reality. The current administration canceled massive renewable projects and has incentivized reopening coal plants, subsidized fossil fuels, and opened government land to oil drilling.

How many degrees hotter will it get as a consequence? How many windmills will it take to make the world a degree colder? Serious question.

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).

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...

1.5% of electricity. That's a significant difference. Only about 1/7th of all our energy usage is electricity

1.5% of global energy use would be a shocking amount. Aviation is at about 3%. 1.5% of global electricity is about 0.2% of global energy use, a much more manageable figure

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

In Sydney it has been raining almost non stop for a year. Really odd. Garden loves it, I'm planting non-endemic native (primarily tropical) species from further north along the coast. I expect a snap-back to extreme drought during this or the subsequent summer. But come further warming, we'll have a jungle.

Ah yes, "just" 485 TWh, equal to all electricity consumption of Germany. Drop in the bucket

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…

Honestly I think American scientists not speaking in Fahrenheit units to an American audience is an incredibly simple and stupid, but very significant cause of the problem.

If I tell you the Earth is going to get 2 degrees C warmer, Americans are going to think, "2 degrees, not that much, barely noticeable." If you tell them it's 4 degrees F, they'll think, that's not a ton, but it's definitely noticeable.

Also, to be more holistic in evaluating things through this icky nationalist lens, China has been a globally significant contributor to alternate fuels including solar and micro-hydro, plus the transition to EVs notably including EV buses (now becoming globally popular) and high speed rail.

This El Niño is going to be interesting come Christmas time. Lot's of weather and climate unpredictability coming to a region near you!

I hope so! The area I live in has been experiencing drought and everyone seems to be predicting a wet period coming from this. Personally, I don't put much faith in weather predictions that are more than a week away.

El nino predictions are pretty spot on. They won't be able to tell you "There will be a storm on the 30th" but they will be able to tell you that you should expect flash floods next year.

Unfortunately for where I'm at, the prediction due to el nino is more drought, which sucks because we are already desperately dry. Hopefully the following la nina year will bring us some moisture.

The big question / risk is whether there are unknown tipping points where things run away. Many are talked about - ice melting, reducing reflectivity, more heating causes more heating etc. But some fraction of these are probably unknowable.

This is the very definition of the Tragedy of the Commons. Without everyone committing to common limits, it is folly for anyone to.

And FWIW, I don't buy the "but the countries that bred like rabbits for the past few decades are owed their due reserved quota". Having a massive population isn't something you need to be rewarded for, not to mention that the math doesn't even make sense. For China and India to get their "per quota" backlog, we're basically so firmly in self destruction territory that it makes no sense for anyone else to even bother.
