The link you post to The Telegraph is merely repost of a blog posting from NZ. The graph he posts is clearly wrong: he is objecting to a set of corrections being made to the data, but then turns around and makes *no* corrections. Here is an explanation: http://www.niwa.co.nz/our-science/climate/news/all/niwa-confirms-temperature-rise/combining-temperature-data-from-multiple-sites-in-wellington Weather stations move or are replaced, and patching one timeseries onto another requires figuring out how to handle data collected in different ways at different times. The NZ warming hasn't gone away, and this shrill report is nonsense.

Why is this article tagged with "democrats"? If you RTFA, you'll note that the tax credit was passed in 2005 and signed by G.W. Bush. In 2005 it was the Republicans that controlled congress.
