  Why was the warming rate from 1910 to 1940 just the same as what our global warminst community worries about, ie, 1977 to 1998?  We did not add significant CO2 until after 1950 according to IPCC scientists.  Was this warming natural? What else could it be? Its funny, but there are more record heat waves world wide in the 1930 than we have now. What gives?
  
  Mark, why have we had no statistically significant warming for the past 20 years despite MASSIVE increases in man made CO2?
  
  I am know that you know the science, so could you provide answers?
