In a recently published paper called "The Truth about Climate Change", a group of climate scientists tell us that,

"By 2015, the global temperature had risen by 1°C above pre-industrial levels, that it is certain to rise another half a degree by 2030 and will continue to rise to 2°C by 2050 unless drastic action is taken to reduce emissions"

The scientists inform us to have any hope of solving the problem, the world needs to reach net zero emissions by 2060 to 2075. Switching to renewables and planting more forests are important components of how to do this, it cannot be achieved by these methods alone, only by deploying carbon capture and storage do they feel can zero emissions be achieved in time.
