From Keith Parkin, Sheffield, UK
In coverage of the direct air capture industry, you mention a plant being built to remove half a million tonnes of carbon dioxide per year from the atmosphere. This apparently impressive figure needs context (25 May, p 12).
In my youth, the colliery in my village was producing a million tonnes of coal per year, and within 20 miles were at least another eight similarly prolific mines. The current plans for carbon capture are frighteningly inadequate. I await, without holding my breath, any mention of this in the pledges for the forthcoming UK election.
