Yes, there are, but the only new process on Earth that has been identified that can account for the significant tipping of Earth's carbon balance is human activity, including deforestation, biomass burning, cement production, and—especially—fossil-fuel emissions.

Despite a run-in with an iceberg and the world’s worst sailing conditions, Saildrone 1020 successfully completed its 13,670-nautical-mile journey around Antarctica, and indicated that parts of the Southern Ocean emit carbon dioxide in winter.

Plants on land have helped slow global warming by capturing nearly a quarter of the carbon dioxide that human activities release in an average year. But where is it all going?

Globally, carbon emissions from fires were near the long-term average in 2014, but North America's emissions were 70% higher than average.

This animation depicts the carbon cycle in a fashion that is suited for younger audiences. The video discusses how carbon enters and exits the environment through both natural and human-driven ways.

This model of ocean-atmosphere interaction shows how carbon dioxide gas diffuses into water, causing the water to become more acidic. The video demonstration and instruction provide an explanation of the chemistry behind this change and the consequences of ocean acidification. The video also addresses a misconception about how ocean acidification affects shelled organisms.

In this 3-part lab activity, students investigate how carbon moves through the global carbon cycle and study the effects of specific feedback loops on the carbon cycle.
