How d'ye know that's the alternative?

Let's do a risk analysis:

Suppose all the scientists concerned about climate catastrophe are
wrong, then you'll be suffering a little inconvenience unnecessarily.
That's not the end of the world.

I don't feel that I need to know for certain that the climate
catastrophe hypothesis is correct. It's just not fair to future
generations to risk it.

Do you think the "end of the world" hyperbole helps? I am sorry to say
that to me it just signals someone who (consciously or not) has bought
into the hyperbolic non-science. And probably also thinks that eating
meat should be banned from 2025.


I couldn't resist the wording. Sorry about that! Runaway climate change
would make life on earth extremely difficult, and that is one of the
possible outcomes. Clearly, the earth would continue to exist.

Can you point to any reliable source that predicts a /runaway/ greenhouse
effect (as distinct from a tipping point effect)? (FTAOD I mean before
the sun moves to its red giant phase.)

You are right. I hadn't realised how unlikely that scenario is.
Nevertheless, there are clearly some nasty tipping points.

Nope.

Or a tipping point effect that would make life difficult (as distinct
from rather scarcer when it comes to large mammals among others)?

Clearly, if semi-arid regions become arid, that will lead to major
difficulties for a significant chunk of the world's population.

Worked out fine the last time that happened.

And its very far from clear that anything we do now will prevent that.
