Bold to assume this planet will still support life in a millennium.
Some life, sure. We’ll extinct untold millions of species on the way out. Michael Crichton, the author of Jurassic Park, was a climate change denier, not a scientist.
Eh. We’re making the planet uninhabitable for us, not for all life necessarily.
Somewhere at the bottom of the ocean, life wont stop for a looooong time unless the sun explodes or the planet gets shattered by something. All life extinct will probably not happen for billions of years.
It’s lasted billions of years. We may largely scour the face of the Earth clean, but archaea will hang around, hiding in the cracks, and more complex life will evolve when conditions are suitable for it
No assumption is safe. We’re playing with forces we don’t understand and consistently finding the results worse than we expect. Life on Earth is a solitary speck of an exception to the norm we’ve found literally everywhere else, which is the complete absence of life.
There is certainly life on Earth more resilient than humans, but even the most hardy of extremophiles have their limit. We cannot claim that our damage to this planet will reverse before that limit is reached. It might, but we have no basis to say it will.
If you look at how much the climate has changed over the last billion years (or heck, the last 3.5) and the events that have happened, it’s tough to imagine life not surviving handily even if a lot of species go extinct.
What we’re doing is going to be traumatic , but it’s nothing like, say, the absolute decimation of life 65 million years ago, etc. And life flourished again not long after.
It actually feels kind of conceited to me to think that we’re even capable of wiping out all life on the planet. Even if full on, worldwide nuclear war l with our entire arsenal broke out, I wouldn’t expect it.
What we’re doing is a 5-alarm fire for us, but for the planet it will be a blip.
We cannot claim that our damage to this planet will reverse before that limit is reached. It might, but we have no basis to say it will.
I just got to this part and that’s a resounding no, even if we dedicated all our resources to it, we couldn’t literally sterilize Earth. I can’t even think of a cosmological event in the next million years that would have this effect.
Earth will be just fine. We will likely be gone by then, but there will be life and it will do just fine. You are seriously lacking knowledge and sense of scale of Earth and the ecosystem and life on a broad scale. Go back to start and try again.

Eh, a million years is a blink in geological history, we have no record in the long, long, long stretch of time before us of earth no longer being able to sustain life, as evident by our being here typing comments on the internet, so it would be WILDLY surprising if this all came to an end right now. (The next million years is “right now” in geological time.)
In about 70 million years we might be ready to talk issues with the carbon cycle, but for the next geological “hour” we’ll likely be facing the same issues as always. Short of a nearby supernova or other event that will cook Earth below the crust, or a collision with a small planetoid, I can’t think of anything that will sterilize Earth anytime soon.
