New study: The long sunspot cycle 23 predicts a significant temperature decrease in cycle 24
Norwegian Scientists: Jan-Erik Solheima, Kjell Stordahlb, Ole Humlum: 'A 1 °C or more temperature drop is predicted 2009–2020 for certain locations. ► Solar activity may have contributed 40% or more to the last century temperature increase. ► A lag of 11 years gives maximum correlation between solar cycle length and temperature'
