Are you for or against climate change RT?
good question(s)!
does the climate change? yes of course, the temp record is not a straight line.
are there patterns in the change or is it random fluctuations/noise? theres obvious patterns.
is it easy to explain and predict these patterns? nope very difficult.
do we understand the processes that drive the climate system? to a large, and increasing, degree yes.
can we model these processes accurately? depending on the process, it ranges from very accurately to not at all.
are mean global surface temps rising, before tipping over into the next ice age? almost certainly.
is it possible for man to influence the climate system? almost certainly.
is man influencing the climate system and accelerating the temp rise? the evidence, although by no means overwhelming, is strong and getting stronger.
should we try to reduce our influence on the climate? given whats at stake I think it would be crazy not to.
will we try to reduce our influence on the climate? very doubtful. people are essentially self-serving. even if the evidence was overwhelming and everyone believed that AGW was happening I dont think people would care or do anything about it. essentially the choice is: carry on as we are and in 100s of years we will be screwed, or modify our behaviour at some personal cost so we are screwed in 1000s of years. numerous examples like the Gambier Islands suggest that we are not good at this stuff.
