Of course we face huge problems at present, but we're also more capable at implementing solutions than we have ever been.

"we are fucked" is a bleak generalisation that can't be rebutted. Regardless, my point remains that people have believed that throughout the ages, and have always pointed to current threats as being more existential than those faced in the past.

There's actually a lot of research into the issue of pessimism about the future. Honestly, it's really interesting and I would challenge you to take a look - you might actually feel a little better about the state of the world. It's a well researched topic but this is a good start.

That's not to diminish the threats we face. Of course we need to take action and avoid complacency, and of course there will be a significant and deleterious impact from climate change, probably even "catastrophic" by some metrics and in some areas. However, I'm confident that as a race we will adapt, survive, and overcome.
