Climate Change Opinion
Book and Movie Reviews
This blog will focus on three stories in the press in the past few months that have been flaring up. They have been smoldering for years and I expect they will smolder for a few more years.
We currently do not know how tornadoes and severe thunderstorms may be changing due to climate change, nor is there hope that we will be able to do so in the foreseeable future. It does not appear that there has been an increase in U.S. tornadoes stronger than EF-0 in recent decades, but climate change appears to be causing more extreme years--both high and low--of late. We may see an increase in the number of severe thunderstorms over the U.S. by late this century.
Elizabeth Kolbert is a writer for the New Yorker magazine. A three-part series she wrote for the magazine in 2005 has been converted into a short, well-researched, and very readable book on climate change called, "Field Notes from a Catastrophe" ($15 from amazon.com). The science presented is excellent, and I couldn't find any errors. Kolbert visits leading climate change scientists in the field, spending time in the Arctic, Greenland, Dr. James Hansen's laboratory, and in United Nations climate change meetings. We get to see the science the way these scientists see it, which is a very powerful way to emphasize the major climate changes that are already underway on our planet.
Kolbert delivers a memorable description of a visit to Alaska, where record temperatures have begun melting permafrost that formed at the beginning of the last ice age, 120,000 years ago. She visits the remote island of Sarichef, five miles off the coast of the Seward Peninsula. A subsistence hunting village has existed there for centuries. However, the entire population of 591 must be relocated to the mainland because the island is eroding away. The problem? Lack of the customary sea ice in the fall has allowed storm surges from the powerful storms that hit during that season to push far inland. Kolbert talks to an Inuit hunter named John Keogak, who lives in Canada's Northwest Territories, 500 miles north of the Arctic circle. He and his fellow hunters started seeing robins for the first time a few years ago. The Inuits have no word for the bird in their language. Kolbert travels to "drunken forests" where the trees lean at crazy angles due to the collapse of the permafrost beneath. In one of many of the odd and amusing observations the book is sprinkled with, she writes:
A few blocks beyond the drunken forest, we came to a house where the front yard showed clear signs of ice wedge melt-off. The owner, trying to make the best of things, had turned the yard into a miniature golf course.
As the title implies, this is not a cheerful book, and Kolbert paints a gloomy picture of the how climate change is affecting the planet. I highly recommend the book for those interested in reading about climate change. Three and a half stars.
