A new research published in the journal Geology has put to rest any long-drawn debate over whether the Sun impacts our planet’s climate in any way, because scientists in the new study prove from extensive research that the Sun actually influences climate changes – mostly when our planet is cooler than at any other period.

According to the scientists, solar activity or a measurement of the radiation coming out from the Sun’s energy impacts some significant change in our climate over a period of time; and this is shown by data analyzed for the past 4,000 years – where some correlation between the variation in the strength of the sun exists between sea surface temperatures during summer in areas of the North Atlantic waters.

The researchers say there was a significantly warm climate during the last 12,000 years which took up a large part of the last Ice Age, even though the climate was still never stable during this time when temperatures changed over time. But the Earth was cooler in the past 4,000 years, making ocean currents in parts of the North Atlantic weaker.

“We know that the Sun is very important for our climate, but the impact is not clear. Climate change appears to be either strengthened or weakened by solar activity. The extent of the Sun’s influence over time is thus not constant, but we can now conclude that the climate system is more receptive to the impact of the Sun during cold periods – at least in the North Atlantic region,” said Professor Marit-Solveig Seidenkrantz of Aarhus University.

The scientists also analyzed diatoms or marine algae found in sea sediments in sea beds in the North Atlantic, helping the researchers to obtain weather and climate fluctuations that occurred in times past.

“Our climate is enormously complex. By gathering knowledge piece by piece about the way the individual elements work together and influence each other to either strengthen an effect or mitigate or compensate for an impact, we can gradually get an overall picture of the mechanisms. This is also important for understanding how human-induced climate change can affect and be affected in this interaction,” said Professor Seidenkrantz.

Publishing their report in journal Geology, the scientists also measured the surface temperatures of seas in the North Atlantic during summer for the last 9,300 years, even though accurate and direct measurements could only be obtained for that of the past 140 years when they were taken from ships.

    Wow !!!
    These guys have a FIRM GRIP of the OBVIOUS..
    The sun effects temperature?
