We see something change in our climate and we blame ourselves ... I don't think we understand what happens. We can watch it happen on the (climate) models, we know it happens, but we don't know for sure how it happens.
Roy SpencerIt is well known that strong to violent tornado activity in the US has decreased markedly since statistics began in the 1950s, which has also been a period of average warming. So, if anything, global warming causes FEWER tornado outbreaks...not more. In other words, more violent tornados would, if anything, be a sign of 'global cooling,' not 'global warming.'
Roy SpencerTemperature measurements in the arctic suggest that it was just as warm there in the 1930's...before most greenhouse gas emissions. Don't you ever wonder whether sea ice concentrations back then were low, too?
Roy SpencerNature is not static, but causes its own, internally-generated changes - both in climate and in biological systems.
