This has resulted in some people suggesting that a similar cooling might offset the impact of climate change.

According to Prof Mike Lockwood of Southampton University, this view is too simplistic.

“I wish the Sun was coming to our aid but, unfortunately, the data shows that is not the case,” he said…

“If you look carefully at the observations, it’s pretty clear that the underlying level of the Sun peaked at about 1985 and what we are seeing is a continuation of a downward trend (in solar activity) that’s been going on for a couple of decades.

“If the Sun’s dimming were to have a cooling effect, we’d have seen it by now.”
