An extremely effective instrument would be to put a price on carbon. It is only through the market that you can get a large enough and rapid enough response [to climate change]

Climate change: It's here. If we don't react, war, pestilence and famine will follow close behind

Unless a price can be put on carbon emissions that is high enough to force power companies and manufacturers to reduce their fossil-fuel use, there seems to be little chance of avoiding hugely damaging temperature increases

Nobody on this planet is going to be untouched by the impacts of climate change.

For me the protection of Planet Earth, the survival of all species and the sustainability of our ecosystems is more than a mission. It is my religion and my dharma.

There is, even today, a Flat Earth Society that meets every year to say the Earth is flat. The science about climate change is very clear. There really is no room for doubt at this point.

Stop worrying about the lousy science, and how me the money already.
