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

Posted by BeauHD on from the cause-and-effect dept.

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.

    The world is not a static system. Of course it will warm up. And cool off. And some things will die and others will flourish. Stop micromanaging it you elitist liberal nitwits.

      So much this.

      The Earth's climate has changed far more radically and far quicker to more extreme states many times in the past and yet here we and all other life are going about living, the silly humans behaving like fleas discussing "what they should do" about their dog in relation to the planet's climate. I would suggest ramping down the irritation you cause before you invite a flea-bath.

      Your theory requires that increasing concentrations of ghg's from 280ppm to 400pm will have no effect on climate. It's up to you to explain how this can happen and not violate the laws of thermodynamics.

      1. The predictions were wrong.

      The second law of thermodynamics is wrong? For some reason, a 4 word explanation on the topic seems to lack a certain preciseness to me.

      2. Freely available in the public record.

      And yet you can't cite it.

    Well, how about looking at a few actual facts:

    But no, lets just live on headlines, funding funding funding! Sad, really.
