We're Creating a Perfect Storm of Unprecedented Global Warming (popsci.com)

An anonymous reader shares a report: If we do nothing to reduce our carbon dioxide (CO2) emissions, by the end of this century the Earth will be as hot as it was 50 million years ago in the early Eocene, according to a new study out today in the journal Nature Communications. This period -- roughly 15 million years after dinosaurs went extinct and 49.8 million years before modern humans appeared on the scene -- was 16F to 25F warmer than the modern norm. [...] During the Eocene, it took more atmospheric CO2 to influence temperatures than it does today. In fact, if we don't change our behavior, 2100 will be as hot as the Eocene with much less atmospheric CO2 than was present at the time. A hotter sun means we get more bang for our CO2 buck. "Climate change denialists often mention that CO2 was high in the past, that it was warm in the past, so this means there's nothing to worry about," said lead study author Gavin Foster, a researcher in isotope geochemistry and paleoceanography at the United Kingdom's University of Southampton. "It's certainly true, that the CO2 was high in the past and that it was warm in the past. But because the sun was dimmer, the climate wasn't being forced as much [as it will be] in the future if we carry on as we are."

    Can anybody tell me more about the humans and their Industrial Revolution that happened 50 million years ago to cause this earlier global warming incident?

    Well, we could point you at the Wikipedia pages that explain all this, but you'll only accuse it of being warmist fake science and cherry-pick this for any uncertainties or unknowns which you can claim disprove the whole thing... While also missing the point that these were changes that took place over tens of millions of years and could have been driven by things like continental drift and very slow variations in orbit or solar output... rather than a few billion stupid apes digging up and burning every scrap of fossil carbon they could find over the course of a mere century.... or the concept that a small initial change in temperature could trigger the release of huge amounts of otherwise sequestered methane...

    From TFS: Climate change denialists often mention that CO2 was high in the past, that it was warm in the past, so this means there's nothing to worry about,

    Of course, in the past, the locations of many of our major cities or key agricultural lands were in the middle of parched deserts or under oceans which would be... inconvenient if it happened again.

    Since when did anyone say the sun didn't have anything to do with warming. For fuck's sake, you fucking retard, it's the fact that CO2 absorbs solar radiation that IS THE FUCKING PROBLEM.

  4. Not switched at all by SuperKendall · · Score: 1, Troll

    I find it interesting that many pooh-poohers have suddenly switched from no, not true, not happening to nothing can be done.

    Non-one has switched anything. Warming on the scale it was supposed to happen, is not happening.

    However you and other Warming Cultists like you are either too stupid or to stubborn to admit this based on evidence, common in the case of so many religions.

    Thus, many of us try to make you feel better by pointing out that even if the warming you are claiming will happen, happens, it would actually be a good thing... this message seems to be able to get through a little better to some of the less addled.

    Sadly we as a species are not that lucky, and once the faked data grows ever wider from reality the truth that the Earth is on the cusp of descending into a cooling period again will hit home. Then the real, and meaningful worrying can begin.

    You are not a denier but an idiot.
    And you are nt worth down modding, what would be the point?
    We rather mod the posts up that are good, informative, insightfull etc. instead of wasting mod points on idiots like you.
