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?

An analysis of the costs of climate change caused by adding one tonne of methane to the atmosphere finds that high-income regions of the world should spend much more on efforts to lower such emissions than should low-income regions.
Our special report examines the role of renewables, nuclear power and carbon capture in reaching this ambitious goal.
Plans to triple the area of plantations will not meet 1.5 °C climate goals. New natural forests can, argue Simon L. Lewis, Charlotte E. Wheeler and colleagues.
There are reasons to be optimistic that the world will break its addiction to fossil fuels. But time is running out.
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.
