Make no myth-take about climate change risks

I have been an admirer of Richard Muller for some time, though I had no idea that he was among the climate change skeptics. One of the reasons I admire him is that he follows the evidence, and in doing so, he came to a conclusion opposite to what his funders had hoped for: “that the Berkeley (Earth Surface Temperature) project would conclude that global warming is a myth.” No myth. No myth-take!

Follow science blogger/children’s author on Facebook

If you are a regular reader of my blog postings, you know that I am a passionate, opinionated middle-of-the-roader. I bring the same passion to my writing for young readers, but I want them to learn to form their own opinions.

Knotty Issue: Drafting Climate Change Policy in the face of scientific uncertainty

One of the best things about speaking my mind in print and on line is that it gives me the chance to “meet” people who are willing to challenge me or share viewpoints that put mine in perspective. Such was the case this morning, when I got an e-mail from Andrew Wright, who wrote an article for Politico.com entitled “Scientific talk on climate change.”

For people who love good children’s science books

I’ve bitten the bullet and created a Facebook page for myself as an author of children’s science books. If you know teachers or librarians who care about good science books for children, or middle graders and teens who might enjoy interacting with an author on Facebook, please send them my way! Scientifically yours, “Dr. Fred” … Read more

Warning for Geo-engineers: SO2 may surprise you

I’ve blogged before about trying to avoid geo-engineering as a solution to climate change. We just don’t know enough about the complexities of climate to try relatively simple fixes, like adding sulfur dioxide to the atmosphere. The following news release from the European Space Agency’s Venus Express program ought to give us pause.

High Seas Ahead?

Probably the greatest missing element in the public discourse about climate change (to characterize the current rancorous political debate with a more benign phrase) is error bars. Too much of the public expects scientific projections of sea level to be well-defined, but climate scientists know that best estimates reported in the most recent report of the Intergovernmental Panel on Climate Change (IPCC) are likely to be much too low because they neglect “dynamic melting” of the Greenland and Antarctic ice sheets.

Climate Change Science for Educated Laypersons

In a recent blog entry, I discussed why professional societies should issue position papers on issues of public importance. That was the topic of an exchange of letters to Physics Today, including mine. Now, as if to emphasize my reasoning, the UK Royal Society has published an excellent and informative 16-page summary of the scientific issues surrounding climate change for general readers.
