Investigadores desarrollan el primer presupuesto integral de gases de efecto invernadero de México

Rachel Fritts, Science Writer by Rachel Fritts 28 June 20242 July 2024

Un nuevo estudio profundiza en dos décadas de datos para crear una cuantificación integral de fuentes de carbono, metano y óxido de nitrógeno que podrían ayudar a guiar las políticas climáticas.

Fifty-Three Experts Weigh in on the Global Methane Budget

Aaron Sidder, freelance science writer by Aaron Sidder 26 June 202415 August 2024

A survey of experts revealed that uncertainty in estimates of global methane levels stems largely from data on fresh water, vegetation, and coastal areas.

Animals Deserve to Be Included in Global Carbon Cycle Models, Too

by Nathaniel Scharping 16 April 202416 April 2024

Because they are far less plentiful than plants and microbes, animals have typically been excluded from examinations of carbon exchange in the atmosphere. But new research shows they may have a considerable influence on carbon cycle dynamics.

Africa’s Carbon Sink Capacity Is Shrinking

Rachel Fritts, Science Writer by Rachel Fritts 4 April 20244 April 2024

A new estimate of Africa’s greenhouse gas budget from 2010 to 2019 shows increasing emissions from cropland expansion, livestock, and fossil fuel use—meaning the continent may have transitioned from an overall carbon sink to a slight carbon source.

Framing the Next Decadal Survey for a Warming World

by Donald Wuebbles 26 March 202422 March 2024

The next decadal survey (DS28) will be framed by a rapidly changing world, and will be critical to consider observational needs of the 2030s-2040s, a world increasingly dominated by climate extremes.

Source or Sink? A Review of Permafrost’s Role in the Carbon Cycle

Sarah Derouin, Science Writer by Sarah Derouin 4 March 20244 March 2024

Understanding the role of permanently frozen soil, which covers a large portion of land in the Northern Hemisphere, is crucial to reaching global climate targets.

Researchers Compare Observations Versus Modeling of Coastal Carbon Cycle

Sarah Derouin, Science Writer by Sarah Derouin 4 March 20244 March 2024

While storing carbon dioxide, the coastal ocean also releases methane and nitrous oxide. New research shows that understanding the impact of coastal oceans on climate requires more research into these fluxes and how they counteract each other.
