Bjorn Lomborg: 'Sadly, accurate science doesn’t make for good television; predicting the end of times does.'
But even this report revealed: “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.”
Report also found: 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.”
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....So, even a 5 percent reduction in the size of the American economy only follows from picking unlikely worst-case scenarios.
The well-reported idea that warming will shrink the economy by 10 percent disregards huge economic growth, assumes twice the damages of the worst-case temperatures the report itself expects and even then only finds such high costs stemming almost exclusively from easily preventable heat deaths.
Conjecturing that the temperature-mortality relationship in the US would remain constant over a century is ludicrous.
Real-world observations contradict Mann’s claims: Dr. Mann claims that “it’s not rocket science” that global warming has led to “unprecedented” extremes in droughts (too little precipitation) and floods (too much precipitation). He insists that we must take “concerted action” to mitigate our use of fossil fuels so as to avert these “disastrous” and “devastating” extreme weather consequences. Mann classifies those who disagree with him about the link between AGW and these extreme weather events as “climate deniers”.
