theconversation : "Some models suggest that up to 1 trillion tonnes of carbon dioxide needs to be removed from the atmosphere to meet the 1.5℃ goal.Scientists spend a lot of effort combating disinformation from the profit system. As soon as they win one argument, another pops up.
This idea is increasingly being called out as a risky and “highly speculative” strategy to limit warming to 1.5℃, as it puts food security and biodiversity at risk, and may not even be possible to deliver. The Convention on Biodiversity has also now weighed in on the issue, declaring that carbon removal techniques are highly uncertain.
A recent report from the Stockholm Environment Institute (SEI), summarised here, argues that the scale of negative emissions assumed by many climate models is improbably high."
History of climate denial/delay
- there is no warming
- ok, there is warming, but it is not man-made
- ok, it is man-made, but it's not dangerous
- ok, it's dangerous, but we have a quick fix
This argument will never be won. We should simply go directly to people and advocate for policy that leads to actual culture-change. For example, if cities were car-free, more people would urbanize and birth rates would fall.
