“While the approximately 0.14° C per decade of global warming seen in the satellite data is minor compared to the scale of some past climate shifts, it reminds us that the natural processes of climate change have not stopped.”

“Looking at the history of paleoclimate data indicates that the climate is capable of significant changes for reasons that are not understood.”

“The current level of knowledge about the climate doesn’t provide the tools needed to predict when rapid natural climate changes will occur and what forms it might take.
This makes it impossible to say with high confidence how much human factors might influence climate change.”

“The first thing is to do no harm. With the threat of catastrophic climate change, many proposals have been put forward to limit energy use.”

“A fundamental point that needs to be understood is that if any of these proposals (including the Kyoto protocol) are implemented, they will have an effect on the climate so small that it cannot be detected.
None of these proposals will change what the climate is doing enough to notice.”
