Why don't world leaders do anything about global warming or global dimming?

Question

They have so much power to change but they're barely doing anything.

Answer 1

Because it is too late to change anything. The damage is already done and it is only going to continue to snowball.

Answer 2

  George Bush didn't believe in it for years and thought the actions people were proposing would destroy the American economy.  Emerging nations consider proposals to be a way of preventing them from becoming as rich as America.  

  And leaders, you might notice, are elected, and get unelected if people lose jobs.

Answer 3

It is an economic issue.  That means legislation.  That means delay.

Also, there are no good alternatives. Additionally, the alternatives we have will take years to come on line.

Nuclear – years to build a new power station

Wind – Not enough reliable wind locations.

Solar – still expensive even with high oil prices

Hydro – mostly tapped out

Geothermal – limited number of sites

Fusion – closer - but still a dream

Answer 4

there is one answer and that is money, people are too short sited even with high fuel cost to realize that a few million $$$ are going to end up saving billions
