One-Degree Rise In Temperature Causes Ripple Effect In World's Largest High Arctic Lake (folio.ca) 303

An anonymous reader quotes a report from FOLIO Magazine: A 1 C increase in temperature has set off a chain of events disrupting the entire ecology of the world's largest High Arctic lake. "The amount of glacial meltwater going into the lake has dramatically increased," said Martin Sharp, a University of Alberta glaciologist who was part of a team of scientists that documented the rapid changes in Lake Hazen on Ellesmere Island over a series of warm summers in the last decade. "Because it's glacial meltwater, the amount of fine sediment going into the lake has dramatically increased as well. That in turn affects how much light can get into the water column, which may affect biological productivity in the lake." The changes resulted in algal blooms and detrimental changes to the Arctic char fish population, and point to a near certain future of summer ice-free conditions. The findings document an unprecedented shift from the previous three centuries, challenging scientists' expectations of how such a large system could respond so rapidly to a one-degree rise. The study has been published in the journal Nature Communications.

  • If they did they would be after ALL nations to clean up. Instead, we have idiots on here trolling claiming that either this is not happening, OR that China does not have to cut back their emissions OR that none of the rest of the 3rd world nations have to cut back.
    And yet, the ONLY ones dropping are the majority of western nations.

    Until we accept that ALL nations have to drop their emissions down to similar levels of Sweden and iceland, AND remove the soot out of their coal plants (IOW, if your skies a

      I think you haven't been paying any attention to what China has been doing. They sure aren't perfect, but they've been working hard to clean up their act.

      Additionally, this is a global problem. But actions are required at the nation level and below. And it's often advantageous for a smaller player to not do their fair share. This doesn't imply that the problem isn't real and isn't severe, it implies that some folk are greedy and don't want to do their fair share. The traditional name of this problem is

      Lets not pretend anything is going to happen. The corporations will continue to lie and pay propagandist to serve this quarters profits margins and their bonuses, ie their funding, funding, funding. They don't care how many die, in fact they get a thrill from causing mass deaths, turns them on.

      Right now the climate models are hugely underestimating the outcomes, why, because they were climate models and not weather models. The problem is climate models tend to reflect stable change and not the reality of l

  • If the temperature of a glacier rises from -0.5C to 0.5C, glacial lakes can disappear within weeks! Who would have thought!

      Do you know at what temperature ice melts? There's your answer!!!

  • As I roughly recall this global warming thing, it went like this: -about 10 years ago big-name Republican politicians were in full agreement with the science. There's a Vox video on it. Look it up. -shortly after, these same politicians suddenly began denying it. The about-face is shocking -Then we've seen this slow progression from the Earth isn't warming, to yes it is but humans aren't causing it, and in some cases claiming the warming is good and will hold off the next ice age When did science become t
