Turning 49 today. I've got a funk I can't shake.

[Mister Ed]

3. Wow, you sure are in a funk.

But, are you sure that the reason the Arecibo scope was not repaired is that we're all doomed anyway? The search for near-earth objects was never its primary purpose.

If scientific organizations were really making policy decisions based on civilization ending within the next century, wouldn't they abandon their efforts altogether?

This is not to downplay the existential threat that climate change presents to civilization. That threat is here, now, on our doorstep, and must be dealt with. In contrast, world-changing collisions with extraterrestrial objects occur only occasionally, across a span of millions of years.
