Nitrogen-fixing bacteria help tropical phytoplankton absorb carbon dioxide, creating a biological pump in the oceans.
Parts of Ethiopia will likely be hotter, drier, and more water stressed - with consequences for human and economic development.
The vast majority of climate scientists agree that rising CO₂ is driving climate change, yet barely 50% of the public agrees. Did scientists get the story wrong? No, as the fossil record makes clear.
A key tool for capturing and storing carbon may have been hiding in plain sight all along.
Don't let stock markets reports convince you that when the markets are up, all is well in the world. When the market is up, carbon dioxide in the atmosphere is up, and the global environment is down.
Technology exists to capture carbon dioxide from the atmosphere but it has a big cost.
It may be just as well the UK government scrapped its previous carbon capture competition.
Consistent carbon pricing is a key element in the fight against climate change.
Air pollution from burning firewood and charcoal is the fourth-biggest killer in many countries.
The fourth episode of our podcast takes on fuel – from Olympic diets to conflict over oil in the Niger Delta.
Tiny organisms change ocean acidity to benefit themselves.
An Icelandic trial shows carbon dioxide can be pumped underground and stored as rock.
Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
Working out how Mars's carbon dioxide was turned into rock could help with carbon capture efforts on our own planet.
February 2016 was the hottest month by the biggest margin ever. Does that mean global warming has gone into hyperdrive?
Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
If shipping and aviation don't rein in their emissions it could seriously jeopardise our goal of preventing more than 2℃ of warming.
New analysis reveals carbon capture at coal power plants is significantly more expensive than thought, making renewables and natural gas power generation more attractive.
Cooperation between regulators and the car industry has led to a huge reduction in dangerous emissions – and we can expect further progress.
Scientists are studying how carbon-rich permafrost known as yedoma acts much like frozen vegetables to hungry microbes -- and is becoming an additional source of heat-trapping gases.
