Nasa has taken time out from its usual work of exploring the galaxy to call out climate change deniers on Facebook. See one hoary example above, of how a legit NASA study can be turned into a pesky climate denial meme. “One user, Fer Morales, took issue with assertion that human emissions are causing the planet to warm, writing: “Riiiiight, despite Nasa confirming that fossil fuels are actually cooling the planet’s temperature, and that there’s more ice than in the last century in the polar caps. And the fact that so-called rises of the sea levels have not materialised, and that any real scientist doesn’t back up man-made climate change at all, since it’s a cycle that has existed even before we did.”
