NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station.

Geological change usually takes thousands of years to happen but we are seeing the climate changing not just in our lifetimes but also year by year.

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.

Evolution is a tightly coupled dance, with life and the material environment as partners. From the dance emerges the entity Gaia.

Composing computer programs to solve scientific problems is like writing poetry. You must choose every word with care and link it with the other words in perfect syntax. There is no place for verbosity or carelessness. To become fluent in a computer lnaguage demands almost the antithesis of modern loose thinking. It requires many interactive sessions, the hands-on use of the device. You do not learn a foreign language from a book, rather you have to live in the country for year to let the langauge become an automatic part of you, and the same is true for computer languages.

China will soon emit more greenhouse gases than America, but its regime knows if it caps aspirations there will be a revolution.

I have a feeling that climate change may be an issue as severe as a war. It may be necessary to put democracy on hold for a while.
