Carbon Dioxide

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?


To keep below two degrees, we’ll need to dramatically reduce current emissions and simultaneously remove 10-15 gigatons of CO2/yr from the atmosphere by 2050. Read on for what that means, why, and how we might do it.
