Unprecedented Heat Wave Near North Pole (www.cbc.ca) 196

Long-time Slashdot reader Freshly Exhumed quotes the CBC: Weather watchers are focused on the world's most northerly community, which is in the middle of a record-breaking heat wave. "It's really quite spectacular," said David Phillips, Environment Canada's chief climatologist. "This is unprecedented." The weather agency confirmed that Canadian Forces Station Alert hit a record of 21 C [69.8 F] on Sunday. On Monday, the military listening post on the top of Ellesmere Island had reached 20 C [68 F] by noon and inched slightly higher later in the day.
A government report in April found that Canada was warming at twice the rate of the rest of the world, and this new article points out that recently records have been beaten "not by fractions, but by large margins." For example, the Alert station's average temperature had been a cool 44.6 F, and Environment Canada's chief climatologist says a deviation of this magnitude is like the city of Toronto reaching a high of 107.6 F.

    Yes, we're in it right now. This is why space is so devoid of coherent EM signals: all civilizations hit the Great Filter: fucked up their own planet before they could leave it. Now it's our turn.

          By believing it's an actual thing much sooner, resulting in funding alternate fuel and power sources decades sooner. Imagine if we'd invented reliable wind turbines a hundred years ago and actually used those, or if we had continued to develop safe nuclear power plants.

          It might not have prevented climate change entirely, but it's very likely it would have slowed it down considerably.

            We couldn't have invented efficient electric generating wind turbines much before we did. What we could have done was put fewer stumbling blocks around their deployment, or even encouraged them. But solar is really more generally promising, and that's still being improved about as fast as we can.

            What we really should have done/be doing is remove the subsidies to coal/oil/gas. And require that they pay for the pollution that they create. This would cause a substantial re-balancing of the economy in a desirable direction. Also we should have pushed the development of fission reactors that were able to use the "waste fuel rods" from the current generation of reactors as fuel. (Burying that stuff is a crime against humanity...we may need that energy.)

            Saying we should have invented efficient wind turbines earlier is rather like saying "we should have invented efficient batteries earlier" after we invent an efficient battery. We're working as fast as we can, sorry but inventions don't come on a human schedule. (I'd say "they don't come on a schedule", but "steam-engine time" is a real thing. Three people tried to patent the telephone within the same month.)

              Wind turbines were just what sprung to mind as I was typing, I wasn't trying to place them as the be-all end-all solution to global warming.

            • Burying that stuff is a crime against humanity...we may need that energy.

              At the Nuclear Waste Management presentation I attended regarding "burying" spent fuel rods, the facility was a giant underground warehouse accessible by elevator. The rods were the size of a lipstick container encased in a coffin-sized container with multiple layers of shielding. Each rod would then be lifted on a regular forklift to sit on a shelf. I don't see a reason why they couldn't just be taken off the shelf and brought back up

              • by HiThere ( 15173 )

                OK. But some of the plans have called for burying them "so far underground they'll never see daylight again". (I think they were planning on using dry oil wells.)

                I think it fortunate that some of the more extreme "solutions to nuclear waste" have never been implemented. That stuff is still a resource, and it's still got a lot of usable energy.

They self-track the wind and self-regulate their operating speed (protecting themselves from high winds), which made them capable of running unattended except for annual maintenance (mostly adding oil). They're mostly used for pumping water.

          When the climate change is man made (as this one is)? There's lots of ways:
          1. Preserving rainforest and other major CO2 consuming environments.
          2. Better containment of released CO2 from industry/consumer processes.
          3. Decreased use of fossil fuels.
          4. Decreased meat consumption.
          5. etc.

          Some options are easier than others.

          • I was with you up until a point.

            Decreased meat consumption.

            Plants need animals to thrive. Allan Savory proved this with his experimentation.
            https://www.ted.com/talks/alla... [ted.com]

            There is nothing wrong with eating meat. That doesn't mean we need to eat more, but it also doesn't mean we need to eat less. We could probably turn the Sahara desert into grassland if we set out to do so. It would take a lot of cattle ranchers and sheep herders to make that happen.

            • The problem is not the meat eating itself. It is the industrial processes around it: clearing forest for grazing lands, transport of meat, and the methane produced by animals eating the particular diets that we feed them. Not to mention the energy put into the whole production. Eating meat is fine (from environmental standpoint) if it is done sustainably. Eat less does not mean none.
              • Eat less does not mean none.

                Okay then, how much meat should we be eating?

                I have no doubt that the answer will always be less than what we are eating now, regardless of how little a person is eating already.

                If it's the industrial processes that bother you then I have a few ideas. Eat local. Getting food locally is already trendy. Raise your meat locally so it doesn't need to be shipped. Use more trains. Trains burn less fuel per mile, assuming they burn fuel at all because electric trains are a thing now. Don't clear the forests.

                • > I have no doubt that the answer will always be less than what we are eating now

                  Nah. In a few years, we'll have artificial, vat grown meat that is indistinguishable from the slaughterhouse variety. Research is in full swing on that. When that happens, "eat less meat" will come off the list. But it would've helped over the last 20 years to have reduced in the meantime.
    • Plus there is the whole pesky inverse-square-law thing, but I like your idea better.

    • Yeah, assuming that other parts of the universe are generally as dangerous as our neighborhood, the odds of a civilization surviving long enough to become space faring has to be pretty low. And that's not even counting the likelihood of local technology destroying themselves. On the other hand, there are lots of stars out there, so still a nonzero chance of someone pulling it off.

      • by HiThere ( 15173 )

        Well, the "great filter" concept includes "the likelihood of local technology destroying themselves". But, yeah, it's still a guess of probabilities. And we *do* still have a chance to pull it off. I wouldn't want to guess at how good a chance, though. I figure that we have to do it within this century, or fail it, but the path to success is still not really clear.

        By my figuring we need to have self-sufficient "colonies" in space to pull it off, but those are going to be social nightmares, so we probabl

      For instance, recently the KNMI (the Dutch national meteo institute) corrected a data series for the de Bilt weather station. The de Bilt series is significant because that's the one that defines national "heat waves" (5 days of temperatures of 25C, with at least 3 of those over 30C). The curious (from a climate change perspective) case is that there were more recorded heat waves (23) from 1901-1951, compared to 19 heat waves in

    A few dead factual and neutrally sourced observations -- flame away:

    1. The current temperature in Alert, Nunavut is 3 C, heading for a high of 4 [theweathernetwork.com].
    2. The forecast for the rest of the week [theweathernetwork.com] is 9, 10, 5, 4, 4, and 5 C (TFA says the average July high is 7 C).
    3. The above link also shows the warm snap lasted less than 4 days, bounded by a high of 12 C on the 13th and 5 C on the 18th.
    4. Alert recorded a high of 20 C in 1956 [strangesounds.org].

    Given that, words like "spectacular" and "unprecedented" seem a bit overwrought.

    • It's sensational.
    • The global mean surface temperature has increased about 1C since 1956.

      That's probably about tripled that far north. So that high of 21C on the 16th of this month, breaking the 1956 record of 20C, needs to be understood in context. If the average monthly high is 7C, and last week hit 14C higher than that, global warming is probably only responsible for 3C of that 14C

      But as the world record for a temperature measured so close to the pole.

      Which is "unprecedented" by definition.
