Bjorn Lomborg is in town on a lecture tour, sponsored, strangely enough, by the right wing IPA.
I read a columnist on Lomborg, who challenged anyone to find an error in his book, the Skeptical Environmentalist.
(I should bring out a book called "The Skeptical Spoon Bender".)
I had a quick browse to find something erroneous, and it didn't take me long.
The Exxon Valdez, P192.
"The oil spill caused heavy oiling of some 200 miles of coastline and light oiling of some additional 1,100 miles of the 9,000 miles of total coastline in the spill region. It is estimated that the spill cost the lives of 300 harbour seals, 2,800 sea otters, 250,000 sea birds, 250 bald eagles and possible 22 killer wales. While this is naturally an awful toll, we need to put this death into perspective - the total 250,000 dead birds from teh Exxon Valdez distaster is still less that the number of birds which die on a single day in the US, colliding with plate glass, or the number of birds that are killed by domestic cats in Britain in two days."
We now look at the source he has given.

I see two problems here.
1) The area in which these birds were killed was a fraction of the area of the US in total, and many of those dying would have been in urban/city areas, where most of the birds are flying pests such as pigeons and sparrows.
If the same proportion of deaths was occurring in the rest of the US, then maybe it would not be such a big deal.
2) The source he refers to says that double the number of birds died from the Exxon Valdez, also many others die due to pollution and Global Warming.
Talk about selective use of statistics. This guy is an expert at it.

Q: What are the effects of other energy sources on birds?
A: Threats to birds from other energy sources include: Oil spills at sea: In a single oil shipping accident--the Exxon Valdez oil spill in Alaska's Prince William Sound--more than 500,000 migratory birds perished, or about 1,000 times the estimated annual total in California's wind power plants.[4]
Tall smokestacks: A study at a single Florida coal-fired power plant with four smokestacks recorded an estimated 3,000 bird kills in a single night during a fall migration.[5]
Mercury emissions: Emissions of mercury, a heavy metal, from coal-fired power plants contaminate lakes and streams and accumulate in the food chain, threatening the common loon and other waterbirds.[6]
Global climate change: The consensus of the world’s scientific community is that rising emissions of greenhouse gases, particularly carbon dioxide (CO2) from the combustion of fossil fuels, are accumulating in the atmosphere and causing the Earth’s climate to change. The changing weather patterns that result are already being blamed for diminishing populations of various species of migratory birds.
