Lancaster University Study Debunks Key Climate Sceptic Argument

A major study by Lancaster University Scientists has seriously challenged the contention of Climate Change "Skeptics" regarding the effect of the interaction of solar activity on cosmic ray intensity. A theory around this, based on the work of Danish scientist Henrik Svensmark at the Danish National Space Center (DNSC) formed a centrepiece of the polemical contrarian TV documentary The Great Global Warming Swindle.

According to the BBC :

The research contradicts a favoured theory of climate "sceptics", that changes in cosmic rays coming to Earth determine cloudiness and temperature.

The idea is that variations in solar activity affect cosmic ray intensity.

But Lancaster University scientists found there has been no significant link between them in the last 20 years.

Presenting their findings in the Institute of Physics journal, Environmental Research Letters, the UK team explain that they used three different ways to search for a correlation, and found virtually none.
