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

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.

Well, how about looking at a few actual facts:

Even without humans there would easily have been that 1C upward swing at some point.

Sounds like an admission that increased concentrations of greenhouse gases are the primary cause of the recent climate change.

Yet a moment ago, I was replying to another poster who claimed the sun (changes in the sun's output) was the cause. Really, it's hard for us to get this narrative straight, because you guys keep contradicting each other. Which of these narratives should we believe now?

It's almost like you reflexively say the first thing that comes to mind, rather than researching and observing to understand the facts behind the observed phenomena.

Yep, "climate change" is euphemism for doubling down on more command and control. Only approved behaviors will be allowed, Nature/ecology be damned.
