Are you saying that one can predict a heavy ragweed season based on global warming numbers or are you saying that there is a predicted heavy ragweed season coming and therefore it must be because of global warming? Either way, there is no other possibility of the cause except global warming. Why not rainfall or local temp fluctuations? Oh yes, again, any variance in seasonal temperatures or precipitation anywhere in the world is of course, due to global warming.

Perhaps all 6.5 billion of us could just breathe a little less every day – you know, do our part. We would reduce human-based CO2 pollution and reduce our pollen exposure at the same time. lol.
