The world lake is heating up

The temperature of large lakes in the world is heating up at a faster rate than air.

Scientists Philipp Schneider and Simon Hook of NASA's Thrust Laboratory used satellite imagery to measure the surface temperature of 167 lakes around the world.

And they announced the startling discovery: the global surface temperature of lakes has increased by an average of 1.1 degrees Celsius since 1985. This is twice as high as the indoor air temperature. same time.

The most heated lakes are Lake Ladoga of Russia and Lake Tahoe of America. Accordingly, the Lake Tahoe rises to 1.7 degrees Celsius, while Ladoga's results are up to 2.2 degrees Celsius. The Nordic region is defined as the place where most lakes increase.

Expert Hook and his colleagues made the above conclusion after studying and comparing infrared thermal imaging of the above lakes in winter and summer. They then collated the data just obtained with data collected from floats floating on the lake surface.

" They are quite similar to what we recorded through air temperature measuring devices ," AFP news agency quoted Hook.

He also said how amazing he and his colleagues are to see that some parts of the lake increase heat even faster than air temperature.

The next question is why the trend is happening. One of the reasons may be that the tank heats up continuously compared to air but slows down.

Climate scientist NASA Gavin Schmidt commented that the study is completely reasonable and provides an independent measuring system to demonstrate the global trend of global warming.

There are 11 different indicators, including air temperature, humidity, snow thickness ., showing how people have affected global warming, according to the Department of Atmosphere and Mass. American Ocean.

Rising heat is the 12th indicator, according to Victoria University climate expert Andrew Weaver.

In total, there are 41 pools that warm up clearly, the other 59 lakes follow the same trend but less, according to Hook.

NASA has chosen to study lakes of 500 km ² or more and have plenty of water to make sure that changes in ground temperature do not affect lake water temperature measurements.
