Scientists have understood the energy capturing nature of airborne carbon (i.e. emissions driven climate change) since at least the 1890s. en.m.wikipedia.org/wiki/Svante_Ar…
The first World Meteorological Conference on Climate came some 80+ years later. google.com/url?q=https://…
Another decade brought Jim Hansen to the Senate to speak on the issue. google.com/url?q=https://…
How's that going? Not that well, actually. Image
If you observe that chart above, you'll notice it measures, not rates of emissions, but cumulative buildup of atmospheric CO2.
Emissions rates look different. But they're not laid out on parallel year scales so it's hard to form a clear mental picture. Image
As of this past week, President Biden hosted a virtual gathering of world leaders at which he promised ("pledged", which may be different, I'm not sure) to reduce the US rates of emissions by 50% of the 2005 rate by 2030.
In English this means, we will continue to add carbon to the atmosphere every minute of every day, but we will add it slower.
But more, more, more every day.
So theoretically, if we do this, this curve will slope down at some point. Image
But this one will continue to slope upwards.
Because adding is adding. Image
Here's another historic curve to observe.
Temperature.
As long as the above curve slopes up, so will this one. Image
I'll be turning 74 this summer, so if the Biden Pledge comes true, in 2030 I'll turn 83, assuming I'm still alive.
At that time, 9 years from today, if everything goes according to plan, this curve will continue to slope upwards. Image
This is known, in media terms, as aggressive action to curb climate change.
I'm not convinced.
But y'all go ahead on.
At least Americans can have more high-tech jobs.
And in the short run, that's all that matters.
Right?
Keep talking. I'll find you. Image

I appreciate all of you who encourage me in my threads. I write them in the hope of literally, as one man, changing the world. I understand that the odds aren't good, but it remains physically possible, not to end or reverse climate change in less than century or two, but to
2. Reduce the rate at which we do increasing damage. We could immediately reduce motor fuel consumption, immediately. Not in 2025 or 2030 but in May of 2024.
This is a physical possibility, a relatively easy and low hassle one.
We could literally save millions of gasoline a year,
3. just with a 55 mph nationalspeed limit that ONLY CLIMATE BELIEVERS OBEY, based on some ⅔ of Americans claiming to be that.

I know it's not worth writing this, but I'm going to anyway.
This (screenshot) came off a pissing contest thread.
Many people strongly believe that we can't do anything about the climate because we are so many.
Actually we can't do anything about it because we don't want to. Image
2. Here's a chart on global energy use from a very few years ago. The general ratios haven't changed, just all the numbers have gotten bigger.
All that matters for this discussion is the sizes of the demands relative to one another.
Over half is industrial use. Image
3. So Prof Bill's question was, you tell me how to reduce emissions by 50% in 66 months?
If we reduce industrial output by half, and reduce transportation speed by half, those two things alone would get us real close.
Absolutely all, without exception all, current "climate action

I despair when I read crap like this.
I despair when I see what climate professionals in the aggregate say. "The stakes could not be higher" is absolutely true. It's where the truth ends.
Their recommendations are pure, unadulterated bullshit. theguardian.com/environment/ar…
2. They quote this woman. Christiana Figueres, UN climate chief.
She presents herself in this article as either a liar or a fool. Image
3. As follows:
Two immediate lies.
"...on the edge of positive societal tipping points away from fossil fuels."
The world has never burned more fossil fuels than the world is burning today.
The only tipping point we're approaching is the one where there's no food or water for us Image

I'm going to try to explain myself to newer readers. I know my ideas are so far out there that I sound crazy.
I'm old, city born and raised, country since age 37. Couple months shy of 40 years out here.
But I earned my living with technology. All of my living.
2. I designed, installed, maintained electronic, and later digital, communication systems, starting in a telephone central office, where all the calls get placed, working on that machine.
It was a fabulous machine, all relays, older than me (I was 21) and did the same stuff
3. as computers do now.
In many of the same ways, except visible to the naked eye.
Relays are digital. They're either on or off. Current either flows or not flows. Same decision trees as machine language. Fabulous machine to work on.
Started back in the 60's. Been a helluva ride.

When I write threads about ecosystem collapse, about global heating, global excess energy accumulation, my (obviously carefully vetted) mostly assume that It Is Over and collapse is inevitable.
Talk about any other topic, and everyone unconsciously assumes all we have now goes on
2. Just as an example, people say it's appropriate to ignore the climate during this election because if this election goes wrong, it's the last one, and we must Save Democracy.
If I'm right - if the ecosystem emergency is upon us - the current organization of the United States
3. is not going to have the physical and technological infrastructure required to run a modern federal government.
There won't be any jets for Israelis to bomb Palestinians with.
There won't be a global supply chain.
At all.
Anything anyone must have to live, if it's at the

We - my brethren / sistren and myself - often speak of #collapse as though it were a foregone conclusion, and I guess to us it is.
But none of us can see the future, and exactly what form this collapse might take we have no way of knowing.
2. I have said, more than once, that possible routes to final irreparable collapse of high energy services, which will be one final step of our current ongoing collapse, include pandemic, international war, local high intensity guerilla war (we already have it at low intensity),
3. at least as likely and probably more likely points of failure than actually running out of oil, even of accessible oil.
I think in the long run we'll leave a lot in the ground.
I don't think the ecosystem will support us long enough for us to burn it all.
And she votes last.
