By Bjorn Lomborg in The WSJ. Excerpts:
"Over the past 11 years Mr. Gore has suggested that global warming had caused an increase in tornadoes, that Mount Kilimanjaro’s glacier would disappear by 2016, and that the Arctic summers could be ice-free as soon as 2014. These predictions and claims all proved wrong."
"The Intergovernmental Panel on Climate Change—in its Fifth Assessment Report, published in 2013—found “low confidence” of increased hurricane activity to date because of global warming. Storms are causing more damage, but primarily because more wealthy people choose to live on the coast, not because of rising temperatures."
"hurricane damage now costs 0.04% of global gross domestic product. If climate change makes hurricanes stronger, absolute costs will double by 2100. But the world will also be much wealthier and less vulnerable, so the total damage is estimated at only 0.02% of global GDP."
"He claims the answer to warming lies in agreements to cut carbon that would cost trillions of dollars. That would not have stopped Sandy. What New York really needs is better infrastructure: sea walls, storm doors for the subway, porous pavement. These fixes could cost around $100 million a year, a bargain compared with the price of international climate treaties."
"the Kyoto Protocol. It did nothing to reduce emissions (and therefore to rein in temperatures), according to a March 2017 article in the Journal of Environmental Economics and Management."
"By 2030 the Paris climate accord will cost the world up to $2 trillion a year, mostly in lost economic growth, according to the best peer-reviewed energy-economic models. It will remain that expensive for the rest of the century."
"if every country fulfills every promised Paris carbon cut between 2016 and 2030, carbon dioxide emissions will drop by only 60 gigatons over that time frame. To keep the temperature rise below 2 degrees Celsius, the world must reduce such emissions nearly 6,000 gigatons over this century"
"0.6% of the world’s energy is supplied by solar and wind. Even with the Paris accord fully implemented, that number would rise only to 3% in a quarter-century."
