Dr. Christy: 'When you look at the United States record of extreme high temperatures you do not see an upward trend at all. In fact, it's slightly downward. That does fly in the face of climate model projections.'
Climate change has been blamed for many things over the years. Never, until now, has anyone thought it was possible to see it as a kind of contraceptive. Hot weather leads to diminished “coital frequency," according to a new working paper put out by the National Bureau of Economic Research. Three economists studied 80 years of U.S. fertility and temperature data and found that when it’s hotter than 80 degrees F, a large decline in births follows within 10 months. Would-be parents tend not to make up for lost time in subsequent, cooler months.
'The research predicts that the threshold may be exceeded, perhaps once a decade or so, by about 2100 in places like Dubai, Abu Dhabi, and along parts of the Iranian coast. So we are talking about very, very hot temperatures, yes—but not on a sustained basis.'
'It’s incredibly harmful when good research like this gets transformed into apocalyptic headlines. Climate change is bad enough—there’s no reason to exaggerate what we know about it...Journalism that exaggerates climate change does so at the risk of being counterproductive, and we just can’t afford any more setbacks at this point—we’ve already waited long enough for effective climate change action.'
