Climate expert calls for decarbonisation tech to help meet Paris targets

Hans Joachim Schellnhuber pushes for afforestation and advances to carbon capture and storage projects to limit global warming

Holding temperature rise to 2C - let alone hitting the aspirational target of 1.5C in the climate agreement concluded in Paris at the weekend - is going to require the deployment of technologies to suck carbon out of the atmosphere, the pope's climate change adviser said.

Hans Joachim Schellnhuber, who provided scientific advice in the drafting of the pope's encyclical, said countries would have to move quickly to build up new solar arrays and wind farms, as well as scale up technologies still in the lab phase, to have any hope of reaching the target.
