They all show a relatively flat temperature profile since 2002, with a peak average somewhere between 2002 and 2006.

Now we have 10 years of flat temperature at the end of the time period from 1977 - 2007 which must drastically reduce the calculated sensitivity from the one calculated looking only at the first 20 years of data.

This variation plus a constant.5 deg / century trend accounts for all of the observed trend since 1850, the increase in slope during the 80s and 90s and the current flat temperature trend.

Earlier this year, a paper by Michael Mann - for years a leading light in the IPCC, and the author of the infamous «hockey stick graph» showing flat temperatures for 2,000 years until the recent dizzying increase - made an extraordinary admission: that, as his critics had always claimed, there had indeed been a» medieval warm period» around 1000 AD, when the world may well have been hotter than it is now.

Additionally, the observed surface temperature changes over the past decade are within the range of model predictions (Figure 6) and decadal periods of flat temperatures during an overall long - term warming trend are predicted by climate models (Easterling & Wehner 2009).

I want to discuss the recent Kaufman study which purports to reconcile flat temperatures over the last 10 - 12 years with high - sensitivity warming forecasts.

Linear trends are appropriate for the time period after 1990 where the data are described well by a linear trend plus interannual noise (that's why we show a linear trend for the satellite sea level in our paper), but they don't capture the longer - term climate evolution very well, e.g. the nearly flat temperatures up to 1980.

If I understand this post correctly, the main thrust is that the over the last decade observed fairly flat temperatures by a small probability still could hide a «true» underlying trend that could be higher than 0.29 °C (or just as likely lower than -0.23 °C / decade)

The IPCC stated right back in the 1990s there will be flat temperature periods of roughly a decade within a longer term rising trend.

Even after numerous climate models failed to predict warming trends and a decade of flat temperatures, Borenstein suggests this study predicts impending doom down to the year.

The «upward move» is less significant than the flat temperature curve since 2000, but I didn't claim that CH4 wasn't to rise anymore in the future, I said that there is no hint of non linear acceleration due to retroaction.

Florrie - And one or two posters have made the argument that when you remove «known» natural forcings, in the current 10 + years of flat temperatures, the residual anthro effect is still seen to be upwards.
