When it comes to storing carbon, alpine peatlands are powerhouses. But feral horse grazing and trampling tips the carbon balance in the other direction. We need to protect and restore our peatlands.
Planting millions of trees in natural grassland is largely ineffective in the battle against global warming because it adds little or no additional carbon storage.
Tracking both the amount of carbon and the time that it remains stored is key to unlocking the potential of nature-based carbon storage as a climate mitigation strategy.
Russia has vast natural resources and is involved in many conservation efforts. Its diplomatic isolation as a result of the war in Ukraine is making it harder to protect many wild species and places.
Brazilian President-elect Luiz Inácio Lula da Silva says he will end land clearance in Brazil’s Amazon region. But powerful forces profit from rainforest destruction.
Our new analysis suggests the vast majority of carbon credits granted for regrowing native forests either has not occurred, or would have occurred anyway.
More carbon dioxide in the air doesn’t necessarily mean more growth for trees, and the increasing risk of wildfires and drought has major consequences, as an interactive map shows.
Canada’s greenhouse gas emissions decreased by only one per cent between 2005 and 2019. A new climate plan charts the path to deep cuts in carbon emissions in only eight years.
Planting trees and preventing deforestation can store carbon in nature, but the effect may only be temporary. If we also eliminate emissions from fossil fuels, even this temporary effect is important.
Seaweed was thought to be a vital tool in the fight to slow climate change. But it turns out seaweed ecosystems may be a natural source of carbon dioxide – and not a sink.
