We _are_ doing something about this. We’re locating concentrated millions of years of trapped fossil energy and moving it into our atmosphere as fast as we possibly can. To a first approximation, that is the world economy. Or did you mean to do something differently?

We have to do less There has been a lot of debate over AC use. Everyone chiming in only discusses runtime energy use. The biggest issue is mining and manufacturing, and the moving of all the materials, parts, and such. Every AC has sheathed wires and circuit boards. Every airplane, car, phone, network router, refrigerator... same expansive mess creation. Gamers complaining about disc less games despite that problem p…

> Gamers complaining about disc less games despite that problem pipeline and waste.

Tbf the issue is the user-hostile parameters of buying a diskless game. Most people would be happy to download their games if they could back them up to a thumb drive and never get locked out of them and sell the game when they’re done with it.

Seems deeply tangential, but it’s not. Blaming people for wanting a physical thing because the alternative is being further abused by a corporation - that’s a miss. Be mad at game platforms for not offering real ownership in whatever the most climate-friendly way possible. Be mad at governments for not forcing companies to cost in the negative externalities of their business.

This is the most important part most people don't get: > And what would 3 °C mean for Germany? > FB: In summer, meteorological records could reach up to 50 °C. Three degrees of global warming does not mean hot days will just be 3 or 4 degrees hotter. It could mean up to 10 degrees hotter. We would also face much longer droughts. 3°C warming implies summer days can get 10°C hotter. This is nightmare scenario.

It's a temperature range and percent likelihood. The warmer the planet, the greater the odds of experiencing these sorts of conditions.

They're not rendered useless. Do you argue the same way about voting too? Ultimately consumption is 2/3s of all emissions, and the majority of it is not billionaires.

Are you saying that no billionaire profits from the consumption of others? And, if some do, do they not maximise that profit by seeking to maximise the consumption of others?

Are you saying no pleb wants to consume? Are you saying no pleb demands more product? Are you saying no pleb wants their polluting employer to continue so they have a job? Are you saying no pleb chooses to lower cost but more polluting options at every turn?

Among _many_ other things, 3 degrees Celsius globally means more evaporation over oceans, which makes the air denser. Denser air carries more momentum, which means more frequent (and more severe) hurricanes.

Greenpeace literature in the 1980s predicted hurricanes from Global Warming. And here we are.

Greenpeace is responsible for a lot of that warming.

On the path we're on I don't think we'll have to worry too much about future generations. The EU has already seeing 10,000 excess deaths from climate changed caused heat waves and this is a minuscule taste of what's to come. A very large percentage of mass extinction events have their roots in increased atmospheric CO2, but all of them on dramatically increased time scales. The closest thing in the history of the pla…

How many excess deaths from cold?

How many die from cold in the summer?

Both Europe and US's emissions are significantly (18%-30%) below their peak (which was 20 years ago. The rest of the world is also moving towards renewables.

How much of that is just outsourcing much of our industry to Asia/etc.?

Yes, this is the right question to ask. A lot of the decrease in emissions in Western nations is the equivalent of dumping your trash in a lot across town. Sure it's "gone", but only in a technical sense.

Are you being intentionally obtuse? In normal language the quoted text means there is a meaningful chance of record temperatures 10 degrees hotter than current records.

Unfortunately Germany phased out nuclear power, but continues to burn coal.

We'll know European Greens are serious about climate change when they stop decommissioning nuclear plants and replacing them with coal.

One major issue is the extreme difficulty of being precise about tipping points. Eg: Have you seen a train derail? A couple of degrees of tilt - nothing .. and then .. whoops. The global climate has been 'stable' about mean values for the bulk of human written history and development of urban civilisations. The planet now hosts 7 billion+ people, largely urban, and feed by a century of stable agriculture patterns wri…

But there have been way higher atmospheric carbon dioxide levels historically, and those have largely coincided with plant and animal life climaxing. See the Jurassic.

I believe those followed global extinction events thanks to large scale volcanic activity over long enough time frames to change the climate. Life did adapt, the life that survived. I'm not sure we want to run that experiment on human civilization.
