I was an avid reader of futurists during the 1970s and '80s. They were so wrong - about everything.

It's too late to stop climate change, that's for sure, but we can still influence the degree of changes and the degree of impacts. We can prepare for a softer landing.

It's always difficult to make predictions about the future.

Nature does not forgive.

I'm not one of those to say Kyoto is not worth the paper it's printed on.

Our resources will diminish in the coming decades at a time when hunger for energy grows dramatically in China and other parts of Asia. Eventually, it will just be impossible to fly - normal flights will become as expensive as flying with the Concorde.

Once the impact of climate change becomes visible, politics will react quickly and forcefully. We saw that in Germany in 2002 during the floods on the Elbe River. They, in fact, determined the result of the (general) elections (later that same year).
