Earth's has gone through major climate changes in the past. They happened on time scales of millions of years and triggered mass extinctions. Our emissions are changing the climate much faster.
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.

Scientists behind a major new study explain how they discovered these forests are becoming less able to sequester carbon.

Without care, reforestation projects can damage ecosystems and be useless as carbon stores. Here's how to go about it the right way.

In the absence of animals to help larger trees reproduce, forests are suffering.
The Amazon’s new record-breaking tree.
The monster trees are almost 90m tall, and may make the Amazon's northeast a much greater carbon sink than previously thought.

The boreal forest is being reshaped by wildfire. As climate change intensifies wildfire activity, the boreal forest will likely become a carbon source.

Boreal forests store one-third of all terrestrial carbon - but for how long?

A new study shows these elephants boost the carbon stored in their forests by 7%.
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.
On March 7, 2019, demonstrators gathered outside the National Assembly in Paris. The sign above reads “Deputies, please save the climate”. The one in front reads “Fossilise the future?”
By enacting a legislative framework to achieve carbon neutrality, France and the United Kingdom are making a difference in the fight against climate change.

The bold pronouncements of 2019 must mean something through the 2020s and beyond.
Why radical changes to society are needed if we are to escape environmental disaster.
Soil carbon can play a role in tackling climate change.
Carbon in soil can help with tackling climate change. Maintaining soil quality by supporting farmers through economic incentives and technical approaches is important.
Farm ponds can act as greenhouse gas sinks.
New research finds that farm ponds actually capture nitrous oxide; this finding can be useful in combatting climate change.
Days of protest by Extinction Rebellion have brought parts of London to a standstill.
The move has been likened to putting the country on a "war footing", with climate and the environment at the very centre of all government policy, rather than being on the fringe of political decisions.
If only it were that easy.

Carbon Engineering's clever harnessing of high-school chemistry is just a small step on the path to negative emissions.
A sperm whale goes down for a dive off Kaikoura, New Zealand.
Protecting forests and wetlands, which absorb and store carbon, is one way to slow climate change. Scientists are proposing similar treatment for marine animals that help store carbon in the oceans.
The exploitation of fossil fuels emits CO₂, the main cause of global warming.
The Earth’s past shows the key role of CO₂ on climate for 4.45 billion years, and how human industrial activity has disrupted its cycle at an unprecedented rate over the past 160 years.
Trapping carbon dioxide in minerals happens naturally over thousands of years. Can humans speed it up – safely?
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.
