Blue carbon is stored in mangroves, seagrass and sediments. Discussions at the UN Ocean Decade conference reiterate the importance of preserving existing sea floor habitats, before it’s too late.
Over two billion years from now, Earth will no longer be able to sustain life. A new study looks at how much life has ever existed and what this means for the discovery of new life-supporting planets.
Current greenhouse gas inventories in Canada only consider “managed” lands. This must change before we can truly understand the scale of Canada’s carbon emissions.
The deal is a global aspiration, not a legally binding agreement. But it should end the idea that burning carbon – in Australia and elsewhere – can continue on a significant scale beyond 2050.
Does the science support the need for a fossil fuel phase out to reach 1.5 C? The answer depends on whether we believe that carbon capture and removal technologies can be deployed safely at scale.
New Zealand’s new government has vowed to explore ‘blue carbon’ options for removing atmospheric CO₂ to meet net zero goals. But first we need a national strategy for this developing field of science.
Brazil’s rainforest is a massive carbon store, so its severe drought could be a tipping point for the global climate. Listen to The Conversation Weekly podcast.
Carbon capture and sequestration can play a role in limiting warming but the nuances of its application are far more complicated than just planting trees. Getting it wrong could make warming worse.
Tackling the climate crisis starts with breaking our addiction to fuel. A task complicated by fuels essential role in both promoting and threatening global human security.
Climate action should be framed not as a sacrifice but as an investment that can generate economic savings and improve human and ecosystem health today.
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.
Peatlands safely store hundreds to thousands of years’ worth of humanity’s toxic legacy but climate change and physical disturbances are putting these pollution vaults, and us, at risk.

Can planting trees help us solve the climate crisis? Probably, but to what extent?
