Climate change

The increasing acidity of our seas is a threat to marine life that for many species may be impossible to overcome.

Is running for office the next step for researchers in the fight against climate inaction?

In the scientific community, the big question is not whether action on climate change is required, but what form it should take — and the part that scientists should play. Three Nobel laureates and three early-career researchers gave their thoughts to Nature on the current state of climate action worldwide and the place of science in society.

Carbon capture and storage will be crucial for mitigating climate change and rebuilding the world's energy infrastructure.

Policymakers are beginning to understand the scale of carbon dioxide removal that is required to keep global warming “well below 2 °C”. This understanding must now be translated into policies that give business the incentive to research, develop and deploy the required technologies.

This Perspective considers the potential mitigation contribution of carbon capture and utilization, such as chemical conversation or to enhance oil recovery. The authors find it will account for a small amount of the required total mitigation effort.

To catalyse climate transformation, we need leadership everywhere. It is time for more of us to take the first steps to lead actively.

Reconstructions of Earth's past are much more than benchmarks for climate models. They also help us comprehend risk by providing concrete narratives for diverse climates.

Following President Trump's withdrawal from the Paris Agreement, cities worldwide have pledged support to combat climate change. Along with a growing coalition of businesses and institutions, cities represent a beacon of hope for carbon reduction in politically tumultuous times.

Christiana Figueres and colleagues set out a six-point plan for turning the tide of the world’s carbon dioxide by 2020.

Carbon capture and storage is considered an important element to meet our climate mitigation targets. This Perspective explores the history of the first wave of projects and what challenges must be faced if widespread deployment is to be successful.
