Letters: No consensus on climate change
Re: ‘The sand’s getting hot, so don’t bury your head in it’ (Metro, May 7)
I admire the fortitude of letter writer Carl Hanson, who claims to have read the latest National Climate Assessment, a document of over 1,000 pages. If he had read more carefully, he would have noticed that the report compares the average temperatures from 1991-2013 with those for the period 1901-1960. The average for the cooling trend from 1961-1990 is omitted. If the missing data were included, the numbers would show a modest decline in average over the last 50 years.

Re: ‘Cool the debate on global warming’ (Metro, May 8)
Contrary to letter writer Ori Feinberg’s assertions, the American Association of Petroleum Geologists does not endorse the concept of manmade global warming and only “quibble” about its extent. The Climate Change page of its website notes that in the last 10,000 years it has been both far cooler and far warmer than it is today, and that while certain climate change simulation models predict warming, any such warming may be within natural variations in climate. In short, they are skeptics. They do say that research into climate change should continue.And the claim that 97 percent of scientists agree that climate change is caused by humans has been so thoroughly debunked that it’s surprising that any well-informed person would repeat it.
