#ClimateChange #CarbonRemoval #USA #Biden: "Let’s start here: Yes, we will probably need carbon dioxide removal, or CDR, to meet the world’s and the country’s climate goals.
This wasn’t always clear. When I started as a climate reporter in 2015, carbon removal was taboo, something that only climate deniers and other folks who wanted to delay decarbonization brought up. An influential Princeton study from earlier in the decade had concluded that carbon removal — especially capturing carbon in the ambient air, a strategy called direct air capture, or DAC — would never pencil out financially and that it would always be cheaper to reduce fossil-fuel use rather than suck carbon out of the sky.
But in 2018, the Intergovernmental Panel on Climate Change made a startling announcement: So much carbon dioxide had accumulated in the atmosphere that it would be virtually impossible to keep global warming below 1.5 degrees Celsius without carbon removal.
The IPCC studied global energy models and found that even in optimistic scenarios, humanity would release too much carbon by the middle of the century to keep temperatures from briefly rising by more than 1.5 degrees Celsius. But if we began removing carbon from the atmosphere, then we could avoid locking in that spike in temperatures for the long term. That is, in order to hit the 1.5-degree goal by 2100, humanity must spend much of the 21st century removing carbon from the atmosphere and sequestering it for thousands of years.
We need carbon removal, in other words, not so we can keep burning fossil fuels, but to deal with the fossil-fuel pollution that is already in the atmosphere."
