Yeah, they'd notice pesky problems like the fact that increases at that rate are so great that it's not possible to have a period of level temperatures. The temperatures would rise by about .15C every other year, not once per decade. They included a chart that had been "smoothed" so much that this actually looked reasonable but if you see the proper perspective on temperatures 4C by 2060 looks absurd Swanson and Tsonis are also advocates of significant multi-decadal internal variation overlaying the forced trend. But their recent paper finds the forced warming trend of the 20th century has been a exponential increase. Effectively without the internal variation they find the early 20th century warming is reduced, the mid 20th century cooling negated and the late 20th century warming reduced. www.pnas.org/content/early/2009/09/09/0908699106.abstractDoesn't mean it's correct, but bear in mind that multi-decadal internal variations in climate doesn't imply the forced trend must be linear. Hmmm, pretty consistent with accelerating sun activity through the 20th century too.

Reading through news.bbc.co.uk/1/hi/sci/tech/8236797.stmThe article says: On average, the region cooled at a rate of 0.2C per millennium until about 1900. Since then, it has warmed by about 1.2C. Then you look at THEIR graph and what do you see? Yes, the warming started in about 1800 not about 1900. Never mind that... from the first sentence we have So... 2000 years ago it was WARMER? That post-inductrial society that Christ came too must have been REALLY burning too many fossil fuels. Note: Whenever they give you a date like that, remember to question it - they are telling you the current (whatever) is less than it was back then, which automatically invalidates their point.

Adelaide latest victim of global water shortages Screamed the headline. If you checked the facts nothing could be further from the truth; www.eldersweather.com.au/damlevel.jsp?lt=state&lc=saMost dams are between 90 -99% full You can complain to the guardian here; reader@guardian.co.uk
