1.5*C ? What kind of fictional reality are living in? We are way past 2.4*C projection and are actually on track for 2.9*C or so. https://www.theguardian.com/environment/2021/nov/09/cop26-se...

Let's be perfectly clear: the projection you are citing is on the extreme end of a spectrum. Other projections differ. Per the (non-headline) part of the article: > The estimate stands in sharp contrast to optimistic forecasts published last week that suggested heating could be held to 1.9C or 1.8C, thanks to commitments announced at the talks, now in their second week and scheduled to end this weekend. > Those estim…

It’s sad, but we will simply never get past the point of rearranging the furniture while we argue about the accuracy of estimates of the iceberg’s size.

Why is this the font of your passion, rather than the desperate situation of our planet?

Nuclear is just a scapegoat. If it was easy or cheap, the free market would have done its magic. All manufacturing would already be done in a country with unlimited free and clean energy, even if other countries had issues with it. Plant costs, operation, safety, waste management, and non-proliferation are real hard problems. It's just lazy and wishful thinking that there's a deus ex machina if some people would just…

Nuclear tech is dual use so it is strongly controlled. That's what makes it impossible for, say, Sudan to become some energy+manufacturing powerhouse in the way you're talking. If you try to start a civil nuclear program and America finds out, America will kill your program. And America will find out.

China or Russia would be entirely powered by nuclear and would be the world's leading industrial nations if it were as easy as proponents suggest. China is the world's leading industrial nation, but their national energy production from nuclear is a quarter of the US's (5% vs 19%). India has a quarter of global reserves of thorium and doesn't have a single commercial thorium reactor.

I used to be really depressed about this sort of thing. It caused me to severely limit my lifestyle out of a desire to "do the right thing". I didn't own a car. Very low consumption and minimal waste (no takeaway food, coffee etc., very frugal, didn't use things like paper towels and napkins). I cycled and walked everywhere. Didn't go on holidays abroad or even very far away. Then I looked around and noticed that eve…

This is exactly why voluntary individual action tends to be really ineffective at stuff like this, absent massive cultural support (e.g. consistent, widespread shaming and shunning those who defect). It's one of the main reasons government is, in fact, useful—it can be impossible to get out of these kinds of holes even when a large majority want to, without someone to make everybody play by the rules.

The core problem is exactly what you noticed: that you can be personally paying, in relative terms, a large cost, while having no meaningful effect, and while others are choosing not to pay that cost and doing much better than you. When the world where you defect is functionally indistinguishable from the one in which you stick with it aside from that you'd be happier in the former, it's hard to justify continuing.

If you're curious on how to do this on linux: - -u then enter unicode char: 00B0 and then press list of unicode codes: https://en.wikipedia.org/wiki/List_of_Unicode_characters#Lat...

This must be desktop-environment dependent? I have to do for °. (That 0 is a zero.)

It's keyboard dependent, but the same for all DEs.

On mine it's copose-/.

Yes, I pulled the numbers from the link you cited. I'm just saying that the nuance here matters a lot, and isn't captured by the headline number.

Barring some dramatic change in technology, we'll probably max out wind generation in the western US in the next decade or two, and it isn't a good solution for the most densely populated parts of the US. Solar isn't growing nearly as quickly (and of course, has the base load problem).

Why do you care about climate change when the world is going to end in nuclear war before we even hit +1.2C?

Don't question my projections, if you do, you're just rearranging deck chairs on the titanic.

Thank god the world is warming. This means a greener world, with more food for everyone. We are just coming out of an ice age; it would be muuuch more worrying if global temperatures were getting colder. Cold periods climatically tend to be associated with famine and war.

There is no chance of removing existing CO2 from Air to make any sort of difference. There is no chance of meaningfully reducing CO2 emissions, because outside of Nuclear (and hydro/geothermal but only if you have the geography for it) there is no alternative to replacing fossil fuels. At some point the public will realize the lie of solar/wind as a replacement. We lost 50 years of greatly reduced emissions had nucle…

> What lie exactly? Scotland had produced enough to power itself twice on Wind alone.

Doesn't say much for a variety of reasons:

- Even in Scotland, there's loads of days where there's "no wind" - on those days electricity has to be generated by gas or other means. So practically speaking as wind cannot be guaranteed it is impossible for Scotland to not generate carbon, via wind alone.

- As usual for breathless wind articles, completely fails to account for heating - which in Scotland makes up the bulk of domestic energy consumption and most homes are heated by gas combi boilers.

- Also as usual, neglects transport - another huge proportion of energy consumption

- Scotland is a best case scenario - it is very windy relative to other countries. It doesn't have a huge population. And as part of the UK national grid it makes sense to build a lot of wind capacity within Scotland. But then looking at statistics for Scotland in isolation doesn't really make sense - it should be done at a UK national grid level rather than trying to gerrymander things.

Wind is fine for reducing gas consumption when it happens to be windy. But if you really want to tackle climate change, you need to tackle having a need for gas consumption at all, and wind won't do it.
