Early life, mistreated coral, the unhealthy rich, and the dubious figures of climate change damage is full of interesting stories today.  Here's one, saying that the start of life on Earth can (perhaps) be pushed back to 4.1 billion years ago. 

Given that the planet only formed at about the 4.5 billion mark, that's pretty quick.

And here's another, this one about how humans, with their use of sunscreens, may be loving some coral reefs to death. 

Then what about this - rich, urban medieval folk were arguably less healthy than those slaving away on farms, all because of lead glazing (and lead roof tiles.)

Finally:  the dubious methods of "normalising" economic damage from climate change (that is, the long running shtick of Roger Pielke Jnr) is probably a crock.   I always suspected that, and I think the lesson is: don't let economists get too involved in climate change policy - they can be a menace to good policy.
