Nature, not human activity, rules the climate.

I am persuaded to think that any climate change is bad because of the investments and adaptations that have been made by human beings and all of the things that support human existence upon this globe. Even minor fluctuations of climate could change the distribution of fish, … upset agriculture,…and inundate costal cities…… Such changes could occur at a faster rate perhaps than human society can evolve.

The Earth is warming but physical evidence from around the world tells us that human-emitted carbon dioxide has played only a minor role in it. Instead, the mild warming seems to be part of a natural 1,500-year climate cycle (plus or minus 500 years) that goes back at least one million years.

Prediction is a very difficult business, particularly about the future

Dabbling in astrology is like carrying a lucky rabbit's foot as an omen of good luck which costs us very little and might have some beneficial effects.

Evidence of warming is not evidence that the cause is anthropogenic.
