Species will endure intolerable conditions long after the global average temperature stabilises.
The UK’s largest wood-burning power plant is to trial bioenergy with carbon capture and storage – but will it do enough to cut emissions?
Machines using giant fans and filters can literally suck carbon dioxide out of the air. Sounds great – but the technology faces many challenges.
Zero emission? Carbon neutral? Carbon negative? What does it mean to achieve ‘net-zero’ emissions?
The Paris Agreement set countries on a path to limit global warming. Five years on, some progress has been made, but not enough. Decarbonizing the economy will take leadership and imagination.
To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.
Canada keeps revising and updating its emissions targets, diverting attention from its failures to make any progress at all.
Countries are not on track to meet Paris Agreement goals. A climate researcher argues that a range of technologies that take CO2 out of the air are needed.
As the UN’s Climate Action Summit approaches, governments need to start doing more than setting targets. Here’s how they can make a start.
Economic growth created the climate crisis and continues to fuel it – ‘green’ growth is no solution.
Carbon Engineering’s clever harnessing of high-school chemistry is just a small step on the path to negative emissions.
Adding industrial chemicals and natural alkaline minerals could slow climate change, but like other geoengineering proposals, it comes with many complex technical and legal challenges.
Earth is fast approaching the red lines that scientists have urged temperatures cannot cross if we have any hope of avoiding catastrophic climate change. Here are the emergency measures we need.
The latest UN climate report makes it clear that the task of limiting climate change is urgent and huge. We must start to transform our economy today, but it will bring rewards as well as challenges.
The UN’s panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
