LOL. If your friend really understood the data behind CO2 warming and the long time scales of cause and effect, he'd know the anthropogenic warming scenario is just another one of those scare tactics in an attempt to gain more global power. You give me data and I'll give you any kind of predictive model you'd like to see. Just another example of today's scientist being forced to think and behave a certain way for fear their funding gets cut off. But planting trees seems harmless enough and might even help lock up some CO2 for a while. And, plants love a rich CO2 environment so should do well.
On another note: I'm 50/50 that's Liau sitting there next to LP. Some of the same features.
I'm not sure how one can do a trial presentation without reviewing the inclusion / exclusion criteria. We should also want a confirmation that longer surviving patients didn't move on to other treatments or receive additional surgeries. DCVAX isn't supposed to be a "Maintenance drug". Because if it is, it needs new trials. We need a better description than "Vaccine" for this.
