Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Beginning investments nuclear at this point when renewables so obviously to everyone in the know are beating them on all accounts is extremely on brand for someone as dumb as Trump
Nope, today nuclear actually makes sense. Renewables are cool and relatively cheap but only as long as they output power. Then what? Spin up that coal power plant such as during night? And produce a ton of climate warming co2 and a lot of pollution. The problem is that we don't have energy storage nor a viable solution for it. Said that, cutting corners is a big no-no.
Nuclear doesn't make sense for that purpose because it'd have to quickly be able to spin up and down. Most reactor designs aren't really able to do it quickly in normal operations, and those that can can't do so in a way that makes any economic sense. They're financially outcompeted by their alternatives.
Storage is the solution, which we can build today in a viable way and is rapidly becoming cheaper and cheaper.
The financial case for nuclear today is shoddy at best. It's why no company wants to touch it with a ten-foot pole unless heavy government subsidies are involved. The case for nuclear in ten years is, given the continuous advancements in renewable energy costs and battery storage tech, almost certainly dead.
Yes, you are right about nuclear output flexibility. Their purpose is to provide stable output, not chime in when required - and that's the problem with renewables - there is no good solution to compensate when they are not producing. Feel free to list those alternative reliable solutions.
And I have yet to see real energy storage data. All I read is just "energy storage is the solution (which, of course, it is, someday)" yadda yadda. So, numbers, please.
Our best current alternative option that's already there is sadly gas. It's fast, cheap and emissions are not the worst of the bunch. Still bad though.
As far as battery storage is concerned, battery prices have dropped 97% in the last three decades (and it's still dropping quite quickly). See https://ourworldindata.org/battery-price-decline for a pretty good overview. And that's not taking into account other forms of energy storage like water-based storage or new batteries based on sodium.
The batteries we have now are already cheap enough to purchase for individual customers, and including solar panels means it's already possible to effectively take houses off the grid. In 10 years those prices will be 50-25% of their current price in pessimistic scenarios. Solar is dropping in price at similar rates.
Yep, gas is a good climate warming enabler. Which we want to avoid since we are fighting climate warming - funny eh, that renewables instead of nuclear causes more gas/coal being burned.
As for batteries, perhaps, but today we don't have any of those at scale required. And while houses could get off grid today with li-ion batteries where lithium is not infinite (nor are rare earths required), it doesn't solve cities and industry or energy storage at scale. Plus those batteries tend to catch fire which is hard to extinguish. Water based storage is limited by geography. And so on.
