More evidence the Sun & cosmic rays drive earth's climate

Meanwhile, a new paper by Henrik Svensmark implicates the sun in global warming - and cooling: Our results show global-scale evidence of conspicuous influences of solar variability on cloudiness and aerosols… From solar activity to cosmic ray ionization to aerosols and liquid-water clouds, a causal chain appears to operate on a global scale. Anthony Watts explains: This paper confirms 13 years of discoveries that suggest a key role for cosmic rays in climate change. It links observable variations in the world’s cloudiness to laboratory experiments in Copenhagen showing how cosmic rays help generate atmospheric aerosols. This is important, because it confirms the existence of a sun-earth atmospheric modulation mechanism for clouds and aerosols. But there’s been a big jump in global temperature for July. Andrew Bolt That Bolter link also has news on Ian Plimer's climate science book, (which sold 20,000 copies within a fortnight here and 30,000 or so over all), being available in the United States now.
