15. Is there a controversy in the science? The Intergovernmental Panel on Climate Change (IPCC) said it was "firmly" standing by findings that a rise in the use of greenhouse gases was a factor. It was responding to a row over the reliability of data from East Anglia University's Climatic Research Unit. Leaked e-mail exchanges prompted claims that data had been manipulated. Last month, hundreds of messages between scientists at the unit and their peers around the world were put on the internet along with other documents. -BBC News

16. Quote 1 “The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t,” Dr. Trenberth wrote. Kevin Trenberth, a climatologist at the National Center for Atmospheric Research, was discussing gaps in understanding of recent variations in temperature with other scientists.

17. Quote 2 “"I've just completed Mike's Nature [the science journal] trick of adding in the real temps to each series for the last 20 years (ie, from 1981 onwards) and from 1961 for Keith's to hide the decline."

18. Some skeptics asserted Friday that the correspondence revealed an effort to withhold scientific information. “This is not a smoking gun; this is a mushroom cloud,” said Patrick J. Michaels, a climatologist who has long faulted evidence pointing to human-driven warming and is criticized in the documents. Some of the correspondence portrays the scientists as feeling under siege by the skeptics’ camp and worried that any stray comment or data glitch could be turned against them.

20. Main points 1.Emails were obtained illegally. It is probably not a coincidence it was immediately before the international meeting in Copenhagen. 2.There appear to only be two particularly damning emails out of the hundreds (or thousands), both of which are interpreted out of context. 3.There is no ambiguity in human-induced global warming. 4.Scientists are people, and everyone has faults. Climatologists, in particular, are under immense public scrutiny.

22. The relationship between science and ethics is very complex. But, the understanding that scientific findings tell us nothing about the ethical implications of those findings. Climate change (and stem cells) are excellent examples of scientific research that are highly ethically charged, yet this is not necessarily a result of the science itself, but of its implications.

23. Perhaps the greatest challenge we face in attempting to fathom the Earth is to gain a proper sense at our own size as a human species; like spoiled children, we routinely overemphasize our own importance on the planet but underestimate the destructiveness of our self-absorption. - M. Bjornrud (geologist)
