Paper finds tiny changes in solar activity explain N Hemisphere temps over past millennium — Paper published in Geophysical Research Letters
'Climate alarmists often claim that tiny changes in solar activity cannot explain the temperature changes of the past millennium. However study finds tiny changes in solar activity of .07% or less can account for changes in Northern Hemisphere [NH] temperature over the past 1,000 years. The paper examines 4 reconstructions of solar activity, each of which show a 'hockey stick' of solar activity in the 20th century'
