Research from the University of Lausanne reveals that Lake Geneva's water temperature is increasing at a rate four to five times faster than that of the oceans. This unprecedented warming trend has pushed the average temperature of the lake's waters to 13.6 degrees Celsius throughout the year.

00:00 The temperature of Lake Geneva's water has hit record levels and is rapidly rising according
00:07 to a new research from the University of Lausanne.
00:10 The annual average has risen to more than 13.5 degrees.
00:15 Scientists say a seasonal phenomenon called winter mixing, in which oxygen-rich surface
00:20 water blends with deep water, has not been seen for years.
00:25 "Globally, we reoxygenate up to 170 metres of bottom, the real question is below.
00:30 It's been 12 years since the bottom of the lake has not been reoxygenated by winter mixing."
00:37 While glaciers in the surrounding Alps are melting at record rates, Lake Geneva's water
00:42 temperatures are rising four to five times faster than those of the oceans.
00:47 But they too are seeing new peaks.
00:50 The EU's Copernicus Climate Change Agency said temperatures in the world's oceans reached
00:55 a record in February.
