I wonder if we are already there :( I remember a year or 2 ago we breached 1.5C for a short period of time.

Let's not delude ourselves. Crypto and AI electricity use is bad, but it's a drop in the ocean compared to the banal, everyday carbon sources that really matter. Even Trump cannot make things much worse in the big picture (he's actually been pretty good at providing reasons to decouple even faster…)

He can continue to propagandize the lie to reduce people's belief in changing is good(and has), change laws to benefit oil companies (and has), and cause wars over oil(and has). Seems like he has plenty he can do to make the current situation worse.

We may lose stable seasons for growing crops, but at least the chat bot can embed an ad into your question while you wait for your burrito taxi. What is the point of this convenience when it really seems to just be making people miserable and isolated? We're driving off a cliff, and our elected government has a death drive.

Worse, they have a "i want to flee responsibility" drive. You can see it in there eyes, when they hold press conferences, while having on the paper the verbose "you are absolutely right". They want the perks, not the responsibility that comes with power.

Stop focusing on energy usage and start focusing on energy generation. It doesn't matter how much energy we consume if it comes from renewables.

What good does PV generated energy make if all that energy is used to generate heat and evaporating water?

It does matter because for now renewables are manufactured mostly with coal and oil EDIT: I'm not a renewable skeptic, answers bellow

They're manufactured once and then generate way more energy than was used to make them.

Trump blocked Hormus, thus stopping oil shipping. Putin blocked gas transfers to the west. They are doing there part.

All of the cradle-to-grave studies I've seen about greenhouse gas emissions for renewables versus coal/oil still indicate massive improvements.

This government meta study of 3,000 such studies puts PV solar at roughly 20x less emissions than coal.

Of course, but pretending consumption doesn't matter in that situation is just silly

Who do you mean "we"? Look at the evolution of CO2 emisions in the past 40 years by region. https://ourworldindata.org/grapher/annual-co-emissions-by-re...

I find that the per capita graph is more informative https://ourworldindata.org/grapher/co-emissions-per-capita?t...

Why does per capita matter when it’s the total emissions that we actually care about?

Wonderful, the United States uses more per capita than anyone else. That doesn’t mean anything in terms of total warming. Even if we cut to zero we still continue.
