Removing carbon from the atmosphere is as much a social problem as a technical one.
While the outcome of the 2021 federal election offered little in the way of change, it may have left Canada better positioned to make progress on reducing greenhouse gas emissions.
Policymakers want to pay farmers for storing carbon in soil, but there are no uniform rules yet for measuring, reporting or verifying the results. Four scholars offer some ground rules.
If problems in such schemes are not addressed, the credibility of soil carbon trading will be undermined. Ultimately the climate - and the planet - will be the loser.
Rather than considering the job done, Tasmania should seize opportunities including renewable energy, net-zero industrial exports and forest preservation.
New UK-wide trials aim to discover the best ways to suck carbon from the air.
Scientists need to know how much we can rely on the land to offset our emissions.
Using tiny ‘soil chips’, researchers have observed the forgaging strategies of fungi at a microscopic scale for the first time.
Peat beds around the world hold huge quantities of carbon and keep it from warming the planet. But rising temperatures and over-use could turn them from a brake on climate change into an accelerant.
As the world’s largest rainforest, the Amazon is not only an important carbon sink, but also home to thousands of species of plants and animals and a crucial part of the water cycle.
We discovered wind farms in Spain that had carved up peat bogs, causing them to release carbon to the atmosphere.
Tree planting projects that use non-native trees risk releasing more carbon back into the atmosphere, undermining efforts to fight climate change.
Microscopic ocean phytoplankton feed a “biological pump” that carries carbon from the surface to deep waters. Scientists have found that this process stores much more carbon than previously thought.
Plants take carbon from the atmosphere as they grow, but it goes straight back when they die or are harvested. There is an important difference between carbon fluxes and actual carbon sequestration.
Storing more carbon in soil helps slow climate change and makes croplands more productive. But there are two kinds of soil carbon that are both important, but function very differently.
Unused biomass residues from maize, sorghum, rice, millet and groundnut in Uganda show to offer unique opportunities for circular production and soil amendment of biochar.
Planting any tree is more important than planting a particular tree when it comes to removing carbon dioxide from the atmosphere.
All plants take up carbon dioxide when they grow, but when they are harvested or cut down, they release the greenhouse gas back into the atmosphere.
Plants live off carbon dioxide, but a higher level of the greenhouse gas in the air doesn’t necessarily lead to more biomass production.
A new report calls land key to solving climate change. The good news is that there are strategies for reducing carbon emissions from land use that can also produce economic and social benefits.
