How fast is Lake Superior warming?

Lake Superior is warming up three times as fast as the global average, which is around 0.61 degrees (0.34 Celsius) per decade. Sharma said Lake Superior's summer water temperatures were warming at the world's second-fastest rate, referring to her previous research.

These lake surface temperatures are projected to rise by as much as 7°F by 2050 and 12.1°F by 2100. Higher temperatures, increased precipitation, and lengthened growing seasons are likely to result in increased production of blue-green and toxic algae in the lakes.

As the summer camping season peaks, the surface temperatures of Lake Superior gradually go from freezing, to tolerable, to relaxing. Our Daily Dips in August at Agawa Bay are by far the warmest and most comfortable since the surface water maxes out at about 20°C (68°F).

As the climate warms and air temperatures increase, Lake Superior's surface water warms, creating higher evaporation rates and altering stratification, which determines water nutrient levels and availability of food sources at different depths, influencing change in the ecosystem.

10% of the entire planet's fresh water are contained in one inland sea. The amount of snow that gets melted and runs into the Great Lakes each year is so vast, that there is zero chance of running low. Droughts don't exist up there. Here in Perth Western Australia we have a dam, little rain and treated water.
