The logic:
"Global warming is there, so it must be man made,
lets bee all better."
is not that convincing.
Though global warming is shown to happen,
it still needs to be researched, if and how much man made technology contributes to it.
Climate cycles happen all the time.
In fact, right now we are in a colder period of Earth climate history. The mean-temperatures change naturally.
Possible appropriate actions to reduce this current increase
must also be prooven.
For example:
lets say we find out that Carbon dioxide emmisions have only
a 5% impact on the warming.
But current agriculture has a 15% impact. (methane)
Then the focus must lie on changing agriculture technology and not
transportation technologies.
If the reasons are not understood, then
the (limited) economical options to change human technology application
cant be applied effectively.
Because we tend to choose the way that's more comfortable for us
This is a simplistic view.
People have to act economically, increasing our utility (well beeing). Not because they are bad or so,
but because if they would not, we would have never evolved
such strong civilizations. (we would not have evolved at all)

Another point:
there where stronger temperature changes than now over the last
5 thousand years of recorded history.
But only now (since 150 year) people do scientific observations
and reasonings about these changes.
So the current climate change is also mangified in perception,
simply beacuse we do actually think and prognose about this
issue now.
