More evidence the Sun is responsible for Global Warming

April 10, 2007

All those eminent scientist will ignore this, but straight from the Beeb:

A new analysis shows that the Sun is more active now than it has been at anytime in the previous 1,000 years….Scientists based at the Institute for Astronomy in Zurich used ice cores from Greenland to construct a picture of our star’s activity in the past.They say that over the last century the number of sunspots rose at the same time that the Earth’s climate became steadily warmer.

But it gets better, because theres even more evidence to suggest that climate change in the past, including cold periods, can be correlated to sun spot activity:

In particular, it has been noted that between about 1645 and 1715, few sunspots were seen on the Sun’s surface.

This period is called the Maunder Minimum after the English astronomer who studied it.

Ice cores record climate trends back beyond human measurements
It coincided with a spell of prolonged cold weather often referred to as the “Little Ice Age”. Solar scientists strongly suspect there is a link between the two events – but the exact mechanism remains elusive.

About it getting hotter:

But the most striking feature, he says, is that looking at the past 1,150 years the Sun has never been as active as it has been during the past 60 years.

Over the past few hundred years, there has been a steady increase in the numbers of sunspots, a trend that has accelerated in the past century, just at the time when the Earth has been getting warmer.

The data suggests that changing solar activity is influencing in some way the global climate causing the world to get warmer.

But it’s all mans fault, right?

One response to More evidence the Sun is responsible for Global Warming

  1. A recent documentary on UK Channel 4 made this very point. The carbon in the atmosphere actually lags rises in temperature by hundreds of years, so how can it cause warming?

    Our Global Warming Latest (.com) site gives a running commentary on this debate, for anyone who’s listening. The evidence now seems conclusive.
