"We know little of the consequences of the geoengineering process, such as spraying particles into the atmosphere that shade the planet from the sun's rays and could decrease its temperature. But this process is how dinosaurs disappeared from the Earth about 60 million years ago, by particles spewed by a volcano or a giant meteorite impact, and our species could follow suit."

I hold that this must be said, for treaties only make sense when concluded by honor-loving peoples and honor-conscious governments. Germany wishes to establish honest relations with the peoples of neighboring countries. We have done this in the East, and I believe that not only Berlin but Warsaw as well will rejoice in the decontamination of the atmosphere brought about through our joint efforts.
