> Climate change: IPCC report is 'code red for humanity' What almost alarms me more than the thought of a climate apocalypse is that I don't think this (a UN report) is going to have any effect on the opinions of 40% of the public who see climate change as some kind of job destroying conspiracy. Nothing short of Florida disappearing under the sea is going to make any difference, perhaps we (as a species) don't deserv…

They see it as a socialist ploy. The best solution is to propose a revenue neutral carbon tax and promise not to use it to increase total revenue. Offer to cut other taxes by a proportional amount and have that as a central part of the pitch. It'll get more political support.

Has any means of geoengineering been demonstrated as feasable? Given our track record, it would probably be best for us to scale back our consumption while promoting re-forestation. Nature can likely heal itself far better than our wildest geoengineering ambitions.

I love the idea of planting trees on every available patch of land too, but won't that just fuel more wildfires at this point?

It’sa good start, but at least an order of magnitude not enough.

China and India are doing it, the Earth is greener today than 20 years ago.

Climate change is bad. Govt are not doing anything. But has any model taken into consideration about covid deaths?

Covid put a minuscule dent into the carbon emmision, but we are basically back to normal.

Death don't have a great effect as the general carbon production (oil, coal, gas) are still rising.

Are these simulations public? Can I run see and run the code? Are all aspects taken into account that can affect the outcome, such as, Earth's magnetic field strength, activity of the Sun, shifting of magnetic poles?

If you have a spare supercomputer I'm sure the scientists would be happy to help you run their stuff. The IPCC report cites its sources, you can go and check who the authors are and what the models take into account.

I found some links for source code here: https://www.easterbrook.ca/steve/2009/06/getting-the-source-... https://www.realclimate.org/index.php/data-sources/#GCM_code

I really liked Bill Gates new Book: How to Avoid a Climate Disaster[1]. I liked that it shows what we have to do to get to 0 greenhouse gas emissions. What's the current state of technology and what's still left to do to get there. I often find suggestions like "Meatless Monday" or "Only fly when really necessary" etc, while probably good, not really useful advice. In Gates book he talks about that transportation and…

I very much agree, and as a bonus, these more optimistic solutions – solutions where we do something instead of (just) stopping doing something – seem easier for people to swallow too.

I agree with everything you say here but feel the ">20 years" hides something. We can easily say 30 years, there are very good arguments to say ~50 years and to get truly technical we could say 70-100 years.

I remember worrying about this as a child, and I'm in my forties now. It's been a long, slow process.

Let's instead get rid of private air travel. Has caused a pandemic and millions of deaths. And the emissions are very likely larger than those of Bitcoin. People can go on vacation by train instead. If you demand people use slow legacy money then I can demand slow legacy travel, ok? ;)

Emissions from aviation contributes 3% to greenhouse gasses.

*historically contributed

Will contribute 6-10% of yearly emission in the coming years

Yes, I didn't want to spread false information because I'm no expert either. ~20 years is the time span I consciously remember reading & hearing about it but I'm sure scientists have warned us for much longer.

As usual the elephant in the room is the global population. We can't eradicate poverty, protect the environment, and maintain the human population we currently have. Bikeshedding is always easier than facing hard issues so people focus on marginal things, like air travel or plastic cups, rather than facing the root cause of it all. Do we want all humans to have a good life with high living standards among a thriving…

Most models forecast a 10bn max pop due to decades long trend of richer countries having lower birth rates.
