We wouldn't be powerless to change, though, if conservatives were not working tirelessly to prevent us from changing. Conservatives are holding the wheel and forcing us off the cliff. And they are mocking us as they kill us.
I don't think there are deer on Antarctica, or any herbivores for that matter. It would be interesting to wait thousands of years and see what comes around to fill that niche.
You're conveniently failing to mention the millions of people who will suffer and die with no fault of their own. This is not positive thinking, it's privilege and ignorace.
Who knows, in 75 million years, maybe there will be tardigrade descendants with extra legs wondering Wtf happened 75 million years ago to wipe out most life.
Eh, there's a difference between will and can, and it's pretty apparent that global climate change can bring about the conditions of the collapse of humanity. Crop growth zones are shifting and shrinking, climate change means more extreme weather, which results in more crop failures as land suitable for large scale agriculture shrinks. Sea level increases result in more salt water intrusion into groundwater, the Atlantic Meridional Overturning Circulation (AMOC) is likely to collapse in the next 70 years, which determines the weather from the equator to Europe, crop production in Africa, and sea level rise on the east coast.
Warmer waters spawn more tropical storms and hurricanes, resulting in more lost crops and infrastructure damage in the south east, an entire years crop of Georgia peaches was lost for the first time after multiple weather impacts. Temperatures in areas unmoderated by large bodies of water are becoming so hot that human habitation is approaching a cost that is untenable across much of the southern US.
At any rate, its not like the sun is just gonna scorch us off the planet, but there are a thousand little things that could collapse international food production, kick off famines as developed nations buy up international supplies, spark conflicts as large populations start migrating from less habitable locations, and nations begin competing for newly limited resources. I'm optimistic that things can be resolved, but we're expecting agriculture production to shrink, waters are already overfished, and animal production relies on agriculture. Enough bad decisions and we can turn a series of collapsing supply chains into a post apocalyptic thriller.
If you don't, you're either an idiot, or an optimist.
Some might say they're the same thing, but I'd disagree.
I HOPE we can get our shit together and maybe with a few lucky breakthroughs, can stabilize the climate and unfuck all the things we've fucked.
But I'm a cynical pessimist, and know even if those breakthroughs DID happen, theres a small percentage of the world who would then pump all their toxic shit into overdrive because "the environment can handle it now"
But still. Hopefully the species survives the next 1000 years. Most probably won't survive the next 150.
Tell that to younger generations in developing countries - they have done nothing wrong and will suffer because of other's actions. It's debatable how much people like you and me - provided you are someone selling labor and consuming averagely living in a developed country like me - can do compared to highly emitting upper-class people, but we certainly can't just accept the consequences of climate change like it only affects us or we are the judges of letting it doom those least responsible but most affected.
