Bjorn Lomborg shreds scientists and media.
“Actually, the assessment, and science, tell a different story. “Drought statistics over the entire contiguous US have declined,” the report finds, reminding us that “the Dust Bowl era of the 1930s remains the benchmark drought and extreme heat event.”
On flooding, the assessment accepts the IPCC’s finding, which “did not attribute changes in flooding to anthropogenic [human] influence nor report detectable changes in flooding magnitude, duration or frequency.”
Even more dramatic was CNN’s headline, screaming that “climate change will shrink [US] economy” by 10 percent, a figure also repeated on The New York Times front page.
Actually, the UN’s climate scenarios envision US GDP per capita will more than triple by the end of this century, so this 10 percent reduction would come from an economy 300 percent larger than it is today. A slightly smaller bonanza, in other words.
But the 10 percent figure is itself dodgy. “
A good article by Bjorn Lomborg.
If our climate conversation managed to include the good along with the bad, we would have a much better understanding of our options. Last week, a study in the prestigious journal Nature revealed just how much CO₂ increases have greened the Earth over the past three decades. Because CO₂ acts as a fertilizer, as much as half of all vegetated land is persistently greener today. This ought to be a cause for great joy.
The biggest study on heat and cold deaths, published last year in Lancet, examined more than 74 million deaths from 384 locations in 13 countries from cold Sweden to hot Thailand. The researchers found that heat causes almost one-half of one percent of all deaths, while more than 7 percent are caused by cold.
Indeed, climate-related deaths have droppedfrom half a million per year in the 1920s to less than 25,000 per year in the 2010s. A recent Nature studyexpecting more severe hurricanes from global warming still found that damages would halve from 0.04 per cent to 0.02 per cent of global GDP, because the increased ferocity would be more than made up by increased prosperity and resilience.
