Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

More than a hundred dolphins have been found dead in the Brazilian Amazon amid an historic drought and record-high water temperatures that in places have exceeded 102 degrees Fahrenheit [38.8 °C].

The dead dolphins were all found in Lake Tefé over the past seven days, according to the Mamirauá Institute, a research facility funded by the Brazilian Ministry of Science.

The institute said such a high number of deaths was unusual and suggested record-high lake temperatures and an historic drought in the Amazon may have been the cause.

The news is likely to add to the concerns of climate scientists over the effects human activity and extreme droughts are having on the region.

If we stopped the economy and stopped all emissions worldwide, this progression would still occur for more than 2 decades.

This is just the beginning for stuff we did since y2k.

By the time we actually make serious change, it will be far too late.

Happy Sunday. Enjoy football.

Forget the progression.

Getting back to pre-industrial CO2 levels will take millenia if we don't do anything.

If we start spending 50% of our energy budget (and let's say that energy generation magically became all renewables and nuclear starting tomorrow) on scrubbing all the CO2 out of the air, we'll still need over a century to get back to pre industrial levels, and that is not counting CO2 storage and or conversions to (for example) plastics. If we include that too then it'll be multiple centuries.

Let that sink on for a second. No matter what we do, none of us, none of our children, none of our children's children will ever see normal CO2 levels in their lives.

And in the meantime we bake, loads of animals will die, food production will be fucked up, and we'll get mass starvation which likely will trigger war for food resources.

I'm painting a pretty picture, don't I? I do fear it's going to be even worse than what I see right now because until now, most climate change predictions actually turned out worse.

We might stand a chance with atmospheric engineering. Start seeding the upper atmosphere with sulfides. They'll cause acid rain over time, but at least block enough sunlight to stop us from cooking. It's done before (80's pollution, volcanos) and it works and we'll need it sooner rather than later

You painted a perfect picture. A wordsmith I am not and loved your version better.

All of us on Lemmy collectively can’t make a fingernail dent into the problem. We have no power to stop it. If we did, we’re labeled terrorists against the economy.
