Analysis: New hockey stick paper shows linear greenhouse forcing over past 7000 years
The paper contains a graph 'showing alleged radiative forcing from ghgs has been increasing at a linear rate for more than 7,000 years, more than 98% of which was before invention of automobile. Human emissions cannot possibly be responsible for a linear increase in greenhouse gas 'forcing' over past 7,000+ years. In addition, the paper shows solar activity at the end of 20th century was near highest levels of the past 8,000 years'
