Prepare For Even More Volatile Weather in 2017 (engadget.com)

An anonymous shares a report on Engadget: Ice isn't just great for keeping your drinks cool at parties, it also helps keep our planet cool by reflecting some of the sun's heat away. But thanks to our steadfast refusal to address climate change, there's going to be a lot less ice in the Arctic next year. Scientists are observing record high temperatures in the Arctic circle that's likely to lead to record low levels of ice coverage in 2017. Long story short, we're currently melting the wall that's helped stop the seas boiling for all of these years. Normally, by November, the global temperature has dropped sufficiently that ice can form again in the Arctic ready for the following summer. This year, however, climate scientists saw a spike to -7 celsius (19f) -- 15 degrees celsius (27f) warmer than usual. While the readings have fluctuated since November 11, they're expected to rocket up again in the next few days.

  1. The seas are NOT going to boil. by emil · · Score: 5, Informative

    Anyone with a cursory understanding of climate over the geologic ages knows that ice at both poles is rare:

    Permanent ice is actually a rare phenomenon in the history of the Earth, occurring only during the 20% of the time that the planet is under an icehouse effect.

    Humans as a species do not have any serious ability to harm the planet. We can easily make it completely unsuitable for human life, however.

    You said: the claims after Katrina hit 11 years ago that THE GULF COAST would see hurricane after hurricane, claiming there would be 3, 4, maybe over half a dozen per year and offered these links as articles that made this claim. Let's take a look.

    Story 1

    This article says nothing about the Gulf coast being hit by 3, 4, maybe over half a dozen hurricanes per year. Just that as there is a observable and measurable correlation between oceans warming and hurricanes growing more frequent and severe.

    Story 2

    This article mostly talks about the fact that hurricanes may become more intense and that a category 6 will eventually have to be created if that happens because hurricanes with windspeed ranging from 257.5 kph to 407 kph are being lumped together into category 5. It goes on to speculate that dumping the category system might be a better idea than creating a category 6. Towards the end it even says: This oscillation means the Atlantic is expected to cool in the future, obscuring links among hurricane activity and global warming. Perhaps counterintuitively, recent computer modeling studies predict fewer tropical cyclones if the ocean heats up further as a result of global warming. But they also predict intensification of the ones that do form, albeit with limited confidence. Frequency drops by 6 to 34 percent this century, according to 2010 review article in Nature Geoscience, whereas intensity rises 2 to 11 percent. (Scientific American is part of Nature Publishing Group.) , i.e. fewer hurricanes but the ones we'll get will be more severe. Nothing about the Gulf coast being hit by 3, 4, maybe over half a dozen hurricanes per year.

    Story 3

    The independent isn't really a scientific source but all this piece says is that somebody found evidence that warmer oceans seem to be linked to an increase in hurricane frequency and that in a warm year hurricanes are twice as likely as in a cold year. The real news here is that somebody found a way to extract data about hurricanes from old measurements made before the satellite age. They say nothing about the Gulf coast being hit by 3, 4, maybe over half a dozen hurricanes per year.

    Story 4

    Still nothing about the Gulf coast being hit by 3, 4, maybe over half a dozen hurricanes per year. It does talk about more hurricanes but the frequency is nothing like you claim: ”If this trend continues, it is realistic to expect a ten-fold increase in hurricanes like Katrina. That amounts to once every two years,”

    Story 5

    And yet again nothing about the Gulf coast being hit by 3, 4, maybe over half a dozen hurricanes per year. This guy talks about improvements in computer modelling since 2005 and seems to be making the case that global hurricane frequency will not increase but that the severity of the hurricanes we do get will increase. I.e. about the same number of hurricanes but they'll be more destructive.

    Yea, you did a search.

    Found all these in less than 1 minute, and everyone voted you up because they want you to be right, but obviously you are not. I like the one claiming Category 6 hurricanes will be hitting any day now.

    Bonus speech by Al Gore saying the same thing.

    Read that long winded piece and it is mostly a regurgitation of d
