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.

Warming of the climate system is unequivocal...most of the global average warming over the past 50 years is very likely due to anthropogenic greenhouse gases increases.

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

Climate change is for real. We have just a small window of opportunity and it is closing rather rapidly. There is not a moment to lose.

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]

What is the difference between Lomborg's view of humanity and Hitler's? ...If you were to accept Lomborg's way of thinking, then maybe what Hitler did was the right thing.

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.
