On a global scale, so far:
So far, the AHF has no relevant climate impact on a global scale. However, given continued growth in a decarbonised world, the AHF can become a relevant factor of post-greenhouse gas warming in the relatively near future within the next century. Also, on a local scale, even today the AHF is a non- negligible process. This holds not only for the direct AHF impact in urbanised areas, but also for remote, large-scale areas like the sea ice near Greenland due to the ice-albedo feedback and impacts on the ocean circulation. The analysis of CLIMBER-3α has shown that a forcing as small as the AHF in the current years (roughly 2% of the CO2 forcing) can influence ocean circulation in such a way that a temperature change of more than ±0.3 K can result in the Arctic region with significant changes in the sea ice cover.

Gotta wonder why so many CDU politicians sit in various supervisory boards of fossil fuel companies? Coal plants were doubled down on and modified. The truth is that Merkel and her party slowed the energy transition drastically because they hate how wind farms make the landscape worse

Nuclear isn’t the one solves all solution either. You’re still looking at heat release as surplus thermal energy because a nuclear reactor isn’t better than a coal plant when it comes to degree of efficiency (around ~30%). Only with renewables that won’t happen because the energy in nature would end up as heat anyway because it’s already in the climate system, wether you use it or not.
This should be taken into account when scaling up.

The current damage done is more or less irreversible (earth will adapt eventually on its own but iirc that’ll take quite some time), so we’ll have to deal with increased flooding, extreme heatwaves, increased frequency of higher category storms etc.
It’s incredibly important that we all adapt to a sustainable lifestyle, science already has the answers but too many expect from science that they find methods to keep on living the unsustainable way of life.
We as society need to come together but imo most importantly always listen to science.
There’ve been mentions of a human-made climate change 140 years ago. All the failed construction projects where they didn’t listen to geologists…etc.
Much can be avoided by listening to science.
