you’re a climatologist and also a climate modeler can you explain to us
climate modeler can you explain to us
climate modeler can you explain to us what climate modeling is we don’t have
what climate modeling is we don’t have
what climate modeling is we don’t have like a hundred different earths that we
like a hundred different earths that we
like a hundred different earths that we can play around with we just have one so

this claim different causes of change
this claim different causes of change have different fingerprints in the

brighter side dinner or what that does
brighter side dinner or what that does is it heats up the whole atmosphere from

is it heats up the whole atmosphere from the bottom all the way up to the top
the bottom all the way up to the top
the bottom all the way up to the top greenhouse gases have a different
greenhouse gases have a different
greenhouse gases have a different signature so they heat up the bottom but

is the course so we can do this kind of pattern recognition and build a kind of
pattern recognition and build a kind of
pattern recognition and build a kind of a balance of evidence so you mentioned
a balance of evidence so you mentioned
a balance of evidence so you mentioned some of the symptoms that we’ve seen in
some of the symptoms that we’ve seen in
some of the symptoms that we’ve seen in the past and we’re seeing now what can

we expect in the future in the American Southwest for instance we anticipate
Southwest for instance we anticipate
Southwest for instance we anticipate that it’s going to get drier
that it’s going to get drier

we’re going to get more intense rain so
we’re going to get more intense rain so that leads to more flooding wildfires
that leads to more flooding wildfires
that leads to more flooding wildfires that depends on moisture availability

during the summertime particularly we’re going to see pests and invasive species
going to see pests and invasive species
going to see pests and invasive species kind of moving poleward moving further
