I hadn't expected an argument on global warming on NB. I actually tried to get away from it as its a pretty sterile debate.
How about the following:
The planet will get warmer
The planet "sort of" warmed up to the late 90s, after which the global mean temperature appears to have stabilized. There are now predictions of cooling as the solar cycle has got longer and solar activity weaker.
There will be an increase in storm frequency and intensity, leading to increased flooding
That hasn't happened. There has been variation in tropical storm intensity from the early 1970s but recent hurricane activity globally has been near historic lows and previous to (just barely) Hurricane Isaac, the US has gone through the longest period of lack of hurricane strikes since the early 20th Century (no hurricanes have hit Florida since 2008)
The Arctic and Antarctic ice sheets will shrink, year on year.
That hasn't happened. Although Arctic ice has shrank, Antarctic sea ice has grown, almost exactly compensating for the Arctic loss
All predictions made 20 - 30 years ago. If you are after "what will the weather be like in my back garden on June the 18th 2034 at 3.17 p.m.", you are going to be out of luck.
I wasn't expecting such precision, but even a cursory glance at what happened to climate over the last 30 years do not support the contentions made in that paper.
All predictive models of complex systems will contain levels of uncertainty, dependant on the sample data set.
But what if the uncertainty is greater than the effect you are trying to isolate?
John, you are an idiot.
Sorry for the size of the images, but I don't know if the BBCode supports width and height parameters
