Rupert Murdoch has a solution for global warming: “Stop building vast houses on seashores.”
That was probably the most sensible thing the media mogul had to say in a Sunday interview with Australia’s Sky News, during which he demonstrated astonishing ignorance about climate science. “We should approach climate change with great skepticism,” Murdoch said. Considering that his media empire is the animating force behind climate denial, this isn’t a shocker. Still, his comments illustrate how the right has hardened its position on global warming—or, as in Murdoch’s case, simply reversed it. This is the same Rupert Murdoch who, seven years ago, warned that global warming “poses clear, catastrophic threats,” and argued, “We certainly can’t afford the risk of inaction. We must transform the way we use energy.”
His comments also reveal how deeply into the bucket of shoddy science skeptics are willing to reach in order to support their claims. Here are the three most egregiously inaccurate statements Murdoch made:
1. “Climate change has been going on as long as the planet is here, and there will always be a little bit of it. At the moment the North Pole is melting, but the South Pole is getting bigger.”
Though it’s true that the earth has previously experienced changes in average temperature, never before has such a large shift happened so quickly. A 2013 study by scientists at Stanford found that climate change is occurring ten times faster than any time in the past 65 million years. It took thousands of years for the earth to emerge from the last ice age; now, the time scale is in decades.
A study finding a 7.5 percent increase in the volume of sea ice in Antarctica is the skeptics’ weapon du jour, promoted recently by the Murdoch-owned Daily Mail as a blow to climate science. But that’s compared to a 75 percent decline in Arctic sea ice. Currently the Arctic is losing ten times as much ice every year as the Antarctic is gaining, so modest gains in Antarctica won’t do much to counter sea level rise. Meanwhile, two separate studies published in May concluded that the Antarctic ice sheet has in fact “gone into a state of irreversible retreat,” suggesting that the accumulation in Antarctica is a temporary phenomenon that will yield to melting ice and sea level rise on a scale even greater than predicted by the IPCC.
