The industrial revolution was the starting point of an ongoing increase in carbon emissions, which inevitably leads to global warming. To avoid a major climate catastrophe, we need to (a) drastically reduce carbon emissions and (b) actively remove carbon from the atmosphere. Will humans succeed in adopting new behaviors and developing life-saving technologies in time?
CO2 could soon reach levels that, it’s widely agreed, will lead to catastrophe.
The atmosphere is literally changing the food we eat, for the worse. And almost nobody is paying attention.
Vast bioenergy plantations could suck up carbon and stave off climate change. They would also radically reshape the planet.
There are reasons to be optimistic that the world will break its addiction to fossil fuels. But time is running out.
Xuemei Bai and colleagues call for long-term, cross-disciplinary studies to reduce carbon emissions and urban risks from global warming.
