Re: Why was Earth a fiery hell 55 million years ago?



While I am at it; anybody got a clue why my posts are now appearing in column 
form? Because I don't ...

No. 
The 
main 
episode 
of 
Deccan 
volcanism 
ended 
100,000 
years 
before 
the 
impact. 
Smaller 
episodes 
happened 
both 
earlier 
and 
later. 
Unless 
the 
impact 
had 
a 
time 
machine, 
it 
didn't 
cause 
any 
volcanism 
in 
India.

BTW...

The 
other 
way 
around: 
it 
gives 
off 
heat 
when 
it 
condenses.
