From Stuart Lambert, London, UK
To argue that a focus on negative emission technologies (NETs) is slowing the fight against climate change is to fall into a common trap. A look at plans drawn up to meet the goals of the Paris Agreement will tell readers that NETs are a baked-in requirement for meeting the 1.5°C pathway(18 February, p 27).
Of the 400 scenarios with a 50 per cent or better chance of ensuring no more than 2°C of warming, 344 assume the large-scale deployment of a NET. We need these technologies.
