A new research reveals that there is a close connection between the activity of the sun and sea temperatures. It has been suggested that its impact is greater when the Earth is cooler.

As per researchers, it is known that the sun plays a part in variations of our weather and for the first time it is observed that sea surface temperatures also get affected by solar activity. It was found by the researchers that over the last 4,000 years, solar activity and the surface of the North Atlantic have a connection.

The researchers said that no connection might be observed before this period. It has been informed that the last Ice Age ended about 12,000 years ago. From that time, the Earth has faced a comparatively warm climate but still unbalanced temperatures over long periods of time have been shown.

According to experts, normally cooler climate with a slight fall in temperatures have been seen in the last 4,000 years. The impact of sun has been unstable over long periods. But the researchers said they are positive that the climate responds more energetically to solar activity during cold times.

They said a major instance of this phenomenon has been witnessed in the North Atlantic region. It has been told that the rescuers examined the surface temperatures of the North Atlantic in summer over the last 9,300 years. According to the researchers, direct measurement of sea temperatures goes back 140 years and for the periods that date back to this time, the researchers decided to study marine algae found in sediments on the ocean floor.

After studying the algae, they found out the fluctuations in temperatures of the surface. The new research has been published in the Journal Geology.
