The US electric power sector is halfway to zero carbon emissions

Fifteen years ago electric power generation was the largest source of US greenhouse gas emissions. Now the power sector is leading the shift to a clean energy economy.

How scientists are restoring boreal peatlands to help keep carbon in the ground

Peatlands store more soil carbon than any other terrestrial ecosystem, including tropical forests. But they have been heavily exploited and damaged. Now, scientists are working to restore them.

We’ve made progress to curb global emissions. But it’s a fraction of what’s needed

The global pandemic caused an unprecedented drop in global emissions. But this is likely to rebound as economies start to recover.

Why a net-zero future depends on the ocean’s ability to absorb carbon

Economic recovery and carbon neutrality are linked. Both depend on the ocean’s ability to continue to regulate climate.

Why is the Earth blue?

The presence of water on the Earth’s surface is the result of a subtle balance between different mechanisms in the atmosphere and below the surface.
Global fossil fuel emissions dropped by about seven per cent in 2020 compared with 2019. But a rebound is likely to occur when lockdowns ease up unless COVID-19 recovery packages focus on ‘green recovery.’ (AP Photo/Michael Probst)

New research suggests 1.5C climate target will be out of reach without greener COVID-19 recovery plans

Several countries have made pledges to reduce their greenhouse gas emissions to zero by mid-century. But new research finds the remaining carbon budget will be depleted before we get there.
