Why is global warming not a threat?

I think that there are couple of ways to make this
argument.

First, you can argue that it is not really
happening.  Some scientists try to make this
argument.

Second, and I think that this is an easier
argument to make, climate change is not necessarily a bad thing.  Let's say that the
world warms up a few degrees.  This might mean that some crops can no longer grow where
they now grow.  But maybe those crops could be grown somewhere else and new crops that
can deal with the warmer weather can be grown where they used to
be.

In other words, so what if now we have to grow grain in
Alaska and we can grow bananas in Kansas -- there will be somewhere for everything to
grow even so.

Alternately, maybe the growing season will
get longer -- you can grow more crops per year because it will get warm earlier in
spring and stay warm later in fall.

In addition, as one of
the links below argues, people enjoy warm weather more than cold and warm weather is
healthier for people than cold
