That’s the problem: it may not be impending but it is urgent. The effects of climate change will get gradually worse over decades, but that doesn’t mean we have decades to fix it. Nor that we can wait until it gets bad before fixing it. How do you instill urgency for a crisis that needs action now, even if the worst effects are still decades in the future?

Excess carbon dioxide remains in the atmosphere for decades to centuries. This year’s pollution might not seem to bad in this year but will make things worse for many years to come.

We still don’t fully understand tipping points but they do exist. What happens when we pass one that “suddenly” makes things even worse, but is irreversible? We may already have started one or more in process and don’t even know it yet.

What the fuck do you think is going to happen once the food riots start, supply chains break down, and people can't afford to feed their kids?

Social collapse on a worldwide scale.

Your right, we don't know how much time we have left, but we know the earth is becoming unsustainable. 4 generations? 10? we can't say.

The fighting over dwindling safe places to live will probably be the actual thing that wipes us out, but the root cause will be the climate change.
