The coming climate crunch

The climate situation may be even worse than you think — this is the theme running through this week’s issue. Three News Features explore the difficulty of cutting back on carbon dioxide emissions and the potential to physically extract carbon dioxide from the atmosphere or cool the planet artificially. Two Letters address the big question of just how quickly greenhouse-gas emissions need to be reduced if we are to avoid dangerous climate change, and a variety of opinion pieces look at policies for managing the climate crisis and coping with climate deterioration. See the Editorial for a full ‘climate special’ contents list.
