Lakes Entrance is warmer and sunnier than most parts of Victoria in winter, when the temperature can rise to 18 - 20 degrees.

The algae may have initially spread across the western side of the lake because of windy weather, but calm weather and warm temperatures after the storm allowed green scum to build on the surface... The bloom now covers much of the western half of the lake.

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?

Loso, M.G. (2008) Summer Temperatures during the Medieval Warm Period and Little Ice Age Inferred from Varved Proglacial Lake Sediments in Southern Alaska, Journal of Paleolimnology 41, 117 - 128, DOI: 10.1007 / s10933 -008-9264-9.

Not surprisingly, we see a long - term increase in lake effect snowfalls as temperatures have warmed during the last century (see figure below).

If we figure say 10 chimneys in each group, and an average of 2 litres per second per chimney, and that the tiny amount of diving has only found 1 % of the vents, and the water temperature coming out of the vents is 80 °C, then they would warm the lake by 1 ° C in about 70 years...

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

These methods have been significantly improved by fully coupling the hydrologic cycle among land, lake, and atmosphere.94, 95 Without accounting for that cycle of interactions, a study96 concluded that increases in precipitation would be negated by increases in winter evaporation from less ice cover and by increases in summer evaporation and evapotranspiration from warmer air temperatures, under a scenario of continued increases in global emissions (SRES A2 scenario).
