Average sea temperatures in Turkey increased by about one degree Celsius in the last 50 years, which Turkish scientists say is a direct result of climate change.

As Turkey is surrounded by three seas, in addition to inland Sea of Marmara the change in sea temperatures has had widespread effects.

"This increase in sea water [temperature] is even more important than air temperature," Istanbul Technical University (İTU) Meteorology Engineering Professor Orhan Şen told Anadolu Agency.

"As the sea water temperature increases, the temperature of the rainfall increases. The result is the droughts, hurricanes, storms, heavy rains and tornados that we have often encountered this year."

Şen also said the temperature change affects agriculture, with decreasing levels of healthy microorganisms in the soil.

The Marmara Sea, surrounded by Turkey's largest city of Istanbul and industrial hubs of Kocaeli and Bursa, had the greatest degree change, with average temperature in 1970 at 15.1 degrees Celsius rising to 16.2 in 2016.

In the first half of this period up to 1998, this number increased by only 0.3 degrees. After 1998, however, the temperature shot up 0.8 degrees.

In 2016, the highest temperature yet was recorded at 17.2 degrees.

In the Black Sea, the average temperature rose from 15.3 in 1970 to 16.4 degrees in 2016.

Mediterranean averages were also up one degree from 21.0 in 1970 to 22.0 last year.

The Aegean Sea recorded the slightest change, up 0.8 degrees to 19.0 from 1970.

Turkey has experienced some of the most severe consequences of global warming in recent years, affecting ecological patterns from seasonal heat levels to rainfall.

The next round of U.N. climate talks is scheduled to begin next week in Bonn, Germany, aimed at advancing and clarifying the guidelines of the Paris agreement, which Turkey has signed and supported since April 2016.
