Say Boris,
Thanks for your reply concerning warming and cooling in the 20th century. However, Waller stated in a follow up post that there is no definitive proof that aerosols were the cause of the cooling from the 1940′s -1970′s. Is there definitive proof to answer this question. Also, your reply concerning the warming in the 1920′s-1930′s was somewhat vague. Your answer to my question concerning, where to start your data from in order to plot a graph left me confused. Who was it that decided that 30 years is a reliable data period. Why isn’t 50 years, 100 years, or 1000 years used? Looking forward to your response.
