«The warming surface waters cause large parts of the lake's floor to lose oxygen, killing off bottom - dwelling animals such as freshwater snails,» Cohen said.

The Michigan Tech chamber works differently due to cloud mixing between a hot and cold surface, the same process that forms clouds or fog over a lake on fall days when the water temperature is warmer than the air temperature.

Surface waters become warm enough (in spring) or cool enough (in autumn) to reach 4 ° Celsius, the temperature at which these waters become dense and sink toward the lake's bottom, mixing the waters.

The Michigan Tech chamber creates clouds through cloud mixing between a hot and cold surface — the same process that forms fog over Portage Lake on fall days when the water temperature is warmer than the air temperature.

Next, I warmed the pinks by adding Crimson Lake (Tint 3) and alternated this with more of the Pansy Violet (Tint 2) to create the subtle ridges in the flower surface.

The paleoclimate record (8.2 kyr, and earlier «large lake collapses») shows a dramatic drop in surface temperatures for a substantial period of time when the ocean circulation shuts off or changes, but is that actually what would be expected under these warming conditions?

1:45 p.m. Updated A study in Nature Geoscience concludes that Lake Tanganyika's surface waters are at their warmest level in at least 1,500 years.

The soil thaws, the surface collapses, lakes form, water flows, land surfaces erode which in turn releases more carbon dioxide to create more warming, to make the tundra even more vulnerable to spring thaw, and of course to accelerated warming.

As you can see, on a single day the surface temperature of the lake varies by 4 ° C from coldest to warmest.

Combine the satellite trend with the surface observations and the umpteen non-temperature based records that reflect temperature change (from glaciers to phenology to lake freeze dates to snow - cover extent in spring & fall to sea level rise to stratospheric temps) and the evidence for recent gradual warming is, well, unequivocal.

Thawing permafrost also delivers organic - rich soils to lake bottoms, where decomposition in the absence of oxygen releases additional methane.116 Extensive wildfires also release carbon that contributes to climate warming.107, 117,118 The capacity of the Yukon River Basin in Alaska and adjacent Canada to store carbon has been substantially weakened since the 1960s by the combination of warming and thawing of permafrost and by increased wildfire.119 Expansion of tall shrubs and trees into tundra makes the surface darker and rougher, increasing absorption of the sun's energy and further contributing to warming.120 This warming is likely stronger than the potential cooling effects of increased carbon dioxide uptake associated with tree and shrub expansion.121 The shorter snow - covered seasons in Alaska further increase energy absorption by the land surface, an effect only slightly offset by the reduced energy absorption of highly reflective post-fire snow - covered landscapes.121 This spectrum of changes in Alaskan and other high - latitude terrestrial ecosystems jeopardizes efforts by society to use ecosystem carbon management to offset fossil fuel emissions.94, 95,96
