Too late for two degrees?

Simplistic analysis but I agree with the conclusions.
This year we estimated that the required improvement in global carbon intensity to meet a 2°C warming target has risen to 5.1% a year, from now to 2050. We have passed a critical threshold – not once since World War 2 has the world achieved that rate of decarbonisation, but the task now confronting us is to achieve it for 39 consecutive years.
The 2011 rate of improvement in carbon intensity was 0.7%, giving an average rate of decarbonisation of 0.8% a year since 2000.
...or, I would argue, a rapidly shrinking economy. Collapse, anyone?Even to have a reasonable prospect of getting to a 4°C scenario would imply nearly quadrupling the current rate of decarbonisation.
