"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:

"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.

I just want to say the fact tht we both have a Lawrence in our names and is purely coincidental.

As Lindzen says there are not thousands and thousands of qualified climate scientist and only twenty years ago you would have been pressed to name more than a dozen. He also says the the extra warming put into the system by C02 is such a small effect and can be enhanced or negated at any given time by natural forcings. Those that seem to think that all hitreto climate change was diven by the tooth fairy who then handed over the resonsiblity to Co2.
