The efficacy of a cap-and-trade system goes way up when it is truly global.

President Lula's proposal is to stop thoughtless destruction of valuable areas of rainforest.

I think that Senator Lugar's advocacy of funds for adaptation to those unavoidable consequences already programmed into the climate system represents one destination for the global cap-and-trade system.

The two areas of the world that have most wanted soil carbon included in the treaty are U.S. farmers and the Continent of Africa.

One way to deal with the flows of immigration into Europe from northern Africa... is to create more economic opportunity there.

I certainly believe that the simplest and easiest way to solve this problem would be a CO2 tax that is 100 percent refundable.

I have grown skeptical about the degree to which it will expand. I'm not opposed to it...

The problem is, the exceptions can kill you, and this is one of them.

This is the most serious challenge the world has ever faced.

Africa is one of the most vulnerable continents to climate change and climate variability.

the solutions to the climate crisis are, in many cases, more easily and readily deployable in regions like Africa

I'm very concerned that the committee version would result in a complete screeching halt to any construction of solar facilities or wind facilities.

First of all, pass the green stimulus provisions of President Obama's recovery plan, and book the CO2 reductions that can come from that plan.

a large and adequate adaptation fund should be a part of this treaty, to help areas like Africa

The most serious defect in the way capitalism has addressed this climate crisis... has been what the economic theorists call 'externalities.'

And then, the third step is to go to Copenhagen, behind President Obama's leadership, and get a treaty that's ratified and allows the U.S. to lead the world again.

we're putting 70 million tons of global warming pollution into the atmosphere each day.

A fair, effective, and balanced treaty will put in place the global architecture that will place the world--at long last and in the nick of time--on a path toward solving the climate crisis.

The real question is whether we pay now in a way that also helps to break our addiction to oil.

The road to Copenhagen is not easy, but we have traversed this ground before.

As long as we continue to depend on dirty fossil fuels like coal and oil to meet our energy needs... we move closer and closer to several dangerous tipping points.

I proposed, as a member of this body many years ago, a full employment alternative for any coal miners and workers in the coal industry that are displaced by the need to protect the environment of this planet.

Captain Climate Change reporting for duty.

As long as we continue to send hundreds of billions of dollars for foreign oil...

If it did expand dramatically, we would run out of fuel in relatively short order, unless we went to reprocessing.
