Video: Counting carbon

The Paris Agreement adopted a target for global warming not to exceed 1.5°C. This sets a limit on the additional carbon we can add to the atmosphere—the carbon budget. Only around 17% of the carbon budget is now left. ...

Reducing industrial carbon emissions

A critical challenge in meeting the Paris Agreement's long-term goal of keeping global warming well below 2 degrees Celsius is to vastly reduce carbon dioxide (CO2) and other greenhouse gas emissions generated by the most ...

Tiny organisms shed big light on ocean nutrients

As the world warms, sweeping changes in marine nutrients seem like an expected consequence of increased ocean temperatures. However, the reality is more complicated. New research suggests that processes below the ocean surface ...

Covid recovery to drive all-time emissions high: IEA

Carbon emissions are set to hit an all-time high by 2023 as just two percent of pandemic recovery finance is being spent on clean energy, the International Energy Agency said on Tuesday.

Hydrothermal vents may add ancient carbon to ocean waters

Earth's oceans play a pivotal role in the global carbon cycle. As seawater moves and mixes, it stores and transports huge amounts of carbon in the form of dissolved organic and inorganic carbon molecules. However, the various ...

Rise of the diatoms—a new timeline

Diatoms—tiny phytoplankton that are responsible for a fifth of all energy converted into matter by plants—may have become important much earlier in the development of Earth's ocean ecosystems and carbon cycle than previously ...

Reducing carbon emissions not enough, expert warns

We are now beyond the point of simply needing to reduce carbon emissions to prevent catastrophic climate change, according to a leading scientist from The Australian National University (ANU).
