Scientists: What We're Doing To The Earth Has No Parallel In 66 Million Years (washingtonpost.com)

mspohr writes from an article on The Washington Post: We haven't seen this much CO2 added to the atmosphere in 66 million years: "If you look over the entire Cenozoic, the last 66 million years, the only event that we know of at the moment, that has a massive carbon release, and happens over a relatively short period of time, is the Palaeocene-Eocene Thermal Maximum (PETM)," says Zeebe. "We actually have to go back to relatively old periods, because in the more recent past, we don't see anything comparable to what humans are currently doing." [New research suggests, even the drama of the PETM falls short of our current period, in at least one key respect: We're putting carbon into the atmosphere at an even faster rate than happened back then.] "The anthropogenic release outpaces carbon release during the most extreme global warming event of the past 66 million years, by at least an order of magnitude," writes Peter Stassen, an Earth and environmental scientist at KU Leuven, in Belgium, in an accompanying commentary on the new study. "Given that the current rate of carbon release is unprecedented throughout the Cenozoic, we have effectively entered an era of a no-analogue state, which represents a fundamental challenge to constraining future climate projections," the study concludes.

..and here comes the deniers

Some will say "That's just, like, your opinion, man. You have no proof humans are causing this."

Some will say "God gave us the Earth, and the end is near anyway so what does it matter?"

Some will say "So it gets warmer, so what? I hate cold weather anyway."

Some will just say "Gee, that's interesting" and get into their SUV and drive off, leaving all the lights and heater running in their house, and they DGAF.

You have no fucking idea how science works. Science advances as data is gathered, theories are refined or new ones are proposed. It isn't some game of topplng windmills. If a theory is invalid, yes it will be rejected, but that is not the sole activity of science, nor, really is it the main activity of science.

Do you seriously think there are scientists in any great numbers running around trying to disprove QM or tectonic plate theories? Is that what you think physicists and geologists are doing? If that is what you think, then you are an ignoramus.
