> The trend is up to now in the low end of the ranges published by the IPCC since 1990 The 1990 IPPC 'that under a "business as usual" (BAU) scenario, global mean temperature will increase by about 0.3 °C per decade during the [21st] century' We saw a warming of 0.8°C in 30 years, and the warming is accelerating. Which means that the BAU base forecast (from 30 years ago!) was on the mark and you should lend credence to the IPCC.

By the way, they also predicted the mean sea level to raise about 20cm by 2030. I think we are not even at 10cm after thirty years, sea level rise is tracking at the low end of the range they gave in 1990.
