You absolutely can have a scientific consensus about whether it's happening at all.
That is the only assertion of the OP.
That tells you NOTHING about FUTURE IMPACT or planning to mitigate. I'll join the 97% "consensus" that you worship because I KNOW the earth has seen a mild warming in the 30 year span that we've had adequate tools to measure the "fever of the earth" to 0.01DegC per year..
Doesn't tell you what the anomaly will be in 2100.
Doesn't tell you how reliable the models are NEEDED to predict it.
Doesn't tell you WHAT TO EXPECT in terms of weather, ocean rise, etc..
THAT QUESTION -- is useless.. And CERTAINLY NOT ENOUGH to sustain a movement asking for WORLDWIDE distribution of money and humbling of economies... m
