“Well, the thing is we’re dealing with an incomplete understanding of the
way the earth’s system works…”

“When we come to the last few years, where we haven’t seen a continuation
of that warming trend, we don’t understand all of the factors that
create earth’s climate, so there are some things we don’t understand,
that’s what the scientists were emailing each other about, you know, we
just don’t understand the way the whole system works, and we’re trying
to find out.”

“These people work with models, computer modelling, when the computer
modelling and the real world data disagrees you’ve got a very
interesting problem, that’s when science really gets engaged. What Kevin
Trenberth, one of the most respected climate scientists in the world, is
saying is, ‘Guys, we have to get on our horses and find out what we
don’t know about the system, we have to actually understand why the
cooling is occurring, because the current modelling doesn’t reflect it.'”

“…sure for the last few years we have gone through a slight cooling
trend…”
