Anthropogenic emissions have already contributed to a 1ᵒ C rise in global temperatures since pre-industrial times. It has been suggested that aggressively and decisively reducing emissions now could still limit warming to below 2ᵒ C, or even 1.5ᵒ C.
The difference between these two scenarios is stark and could prove to be disastrous for certain ecosystems and populations. But merely limiting emissions will not be sufficient to meet these climate targets. We will also need mechanisms to capture and remove what we've already emitted to achieve a net-zero.
Can CCS strategies and negative emissions technologies (NET) overcome the challenges of radical economic and technological inputs, the absence of regulatory and governmental support, and major land and environmental impact concerns to make the future of carbon management plausible?
