"A few weeks ago, scientists at the University of Washington found
that man’s contribution to global warming may have been exaggerated –
by a factor of two. The natural cycle of heating and cooling, they
discovered, plays a far bigger role than they had imagined."



As neither a denier, nor an alarmist, I found this research
interesting, and would be interested as a teacher to read more about
it. Anyone have a link?

I think it's this one:

http://www.pnas.org/content/110/6/2058.short

"After reviewing evidence in both the latest global data (HadCRUT4) and
the longest instrumental record, Central England Temperature, a revised
picture is emerging that gives a consistent attribution for each
multidecadal episode of warming and cooling in recent history, and
suggests that the anthropogenic global warming trends might have been
overestimated by a factor of two in the second half of the 20th century."

Looks like you will need to pay for the full article though.
