Green sea turtles do not develop into males or females due to sex chromosomes, like humans and most other mammals do. Instead, the temperature outside a turtle egg influences the sex of the growing embryo. And this unusual biological quirk, scientists say, endangers their future in a warmer world. Already, some sea turtle populations are so skewed by heat that the young reptiles are almost entirely female, according to a new report in the journal Current Biology.
Wash Times: Climate skeptics were quick to mock activists for connecting the winter freeze to global warming, pointing out that Mr. Gore as recently as 2009 warned of vanishing snow and ice. “The media is intent on featuring every flood, hurricane, drought, tornado, heatwave — and now cold snaps and snowstorms — as proof of ‘global warming,’” said Climate Depot’s Marc Morano, author of “The Politically Incorrect Guide to Climate Change” (Regnery, 2018). “Never mind that the media used to claim that the polar vortex was a sign of global cooling back in the 1970s,” Mr. Morano said in an email. “Never mind that climate activists warned repeatedly that snow would be a thing of the past due to ‘global warming.’”Mr. Morano suggested environmentalists have overplayed their hand. “But now we are told more snow is due to global warming. Is this what climate science has turned into?” he asked.
