One of the constants of the "climate change" coverage is they always trot out the biggest morons to talk about it, be it politicians, columnists or reporters. There is nothing in any model worse than "really bad", for example a meter sea level rise in 100 years (currently rate is 30 times too low for that to happen). There is nothing in any models about even "really bad" weather, in fact most models show more benign weather except for tropical storms which is a small subset of weather.
In fact global warming is beneficial but the columnist would not know that. In fact he knows nothing and that's the point of him writing his pieces on it.
Yep, last time I read anything about this, the rise was 2mm/year. Which begs two questions:
How can scientists measure an oceanic rise of 2 mm? (they can't...)
200mm equals about 8 inches a century. Would anyone notice? (nope)
