Wall Street Journal article repeats multiple incorrect and misleading claims made in Steven Koonin’s new book ’Unsettled’
Scientists who reviewed the article found that it builds on a collection of misleading and false claims. For instance, Koonin states that “Greenland’s ice sheet isn’t shrinking any more rapidly today than it was eighty years ago”. Contrary to the claim, scientific studies using airborne and satellite altimetry observations show considerable thinning has occurred along the margin of the Greenland ice sheet since 2003.
It's true that the current carbon dioxide level is higher than any time in human existence
Claim:
the concentration of carbon dioxide in Earth’s atmosphere has climbed to a level last seen more than 3 million years ago — before humans even appeared on the rocky ball we call home
Scientists explain what New York Magazine article on “The Uninhabitable Earth” gets wrong
“While it is clear that ongoing warming of the global climate would eventually have very severe consequences, the concept of the Earth becoming uninhabitable within anywhere near the timescales suggested in the article is pure hyperbole. The author has clearly done very extensive research and addresses a number of climate threats that are indeed major issues, but generally the narrative ramps up the threat to go beyond the level that is supported by science.”
Analysis of "Scientists say human greenhouse gas emissions have canceled the next ice age"
“The article presents an accurate account of recently published research which suggests that human-induced global warming will delay the onset of the next ice age by 50,000 years. The research supports the findings of several studies published over the past 15 years, and is consistent with the scientific consensus that human activity is changing the climate with very long-term consequences.”
