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.

Re:The world is not a static system

Imagine if the Sun's output is also not static or constant...

So your theory is that changes in the Sun's output are causing the recent rise in temperature?
1. What happened to the warming that should have occurred (and was predicted to occur) due to increases in greenhouse gases?
2. Where is the observational data to evidence your theory?

I think he did daily measurements at Noon and Midnight for quite some time... The Sun was "hot" at Noon and "cold" at Midnight - so not static.
