  1. No warming has happened since this was made. There is no climate emergency. The Earth was warmer in the recent and distant past. It also warmed faster in the past.

  2. Current warming is smaller than predicted by nearly all models (0.13°C per decade since 1979, UAH v6) so around ½°C for the past 40 years but no overall warming over the past 8. This will result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°. Please be aware that the IPCC's (Scenario A) modelled predictions are junk. Back in 1990 they predicted a warming of 0.30-0.34°C per decade. Of course we've only had 0.13°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it. But there is still no crisis just an unexciting set of observations.
