Silvopasture Can Mitigate Climate Change. Will U.S. Farmers Take it Seriously?

By Lela Nargi Photo: USDA National Agroforestry Center

The ancient, sustainable practice of pasturing animals among trees is gaining traction in the U.S. If it scales up, it could help shrink our carbon footprint.

Sparing vs Sharing: The Great Debate Over How to Protect Nature

By Fred Pearce Photo: Ulet Ifansasti/CIFOR

Americans Have Planted So Much Corn That It’s Changing the Weather

By Eric J. Wallace Photo: Craig Chandler / University of Nebraska

More corn means more transpiration. Which, in turn, produces slightly cooler temperatures and increased precipitation. The fact that corn is a non-native species boosts the effect.

To share or not to share?

By Paola Rosa-Aquino Photo: Amelia Bates/Getty

Native communities are one of the groups most impacted by a changing climate — and many of the human activities that have precipitated it. They are also a necessary part of the solution, according to the newest Intergovernmental Panel on Climate Change (IPCC) report.

5 Major Crops In The Crosshairs Of Climate Change

By Dan Charles Photo: Heather Kim/NPR

Climate change is coming like a freight train, or a rising tide. And our food, so dependent on rain and suitable temperatures, sits right in its path.

Compost: Secret Weapon Against Climate Change?

By Sarah West Photo: Getty

Fossil fuels can only release carbon into the atmosphere, but soil – and the vegetation that covers it – is a two-way street. Through photosynthesis, plants absorb carbon dioxide, storing it in their roots and transferring some to the soil. When they die, the process of decay releases carbon back into the atmosphere. By turning the soil and focusing on short-term annual plants, farming generally helps soil release carbon.

Rising CO2 will leave crops—and millions of humans—less healthy

Increasing levels of carbon dioxide in the atmosphere will render some major crops less nutritious and leave hundreds of millions of people protein and zinc deficient over the next three decades, according to a new study.

Grasslands More Reliable Carbon Sink Than Trees

By Kat Kerlin Photo: Getty Images

Forests have long served as a critical carbon sink, consuming about a quarter of the carbon dioxide pollution produced by humans worldwide. But decades of fire suppression, warming temperatures and drought have increased wildfire risks — turning California’s forests from carbon sinks to carbon sources.

The Nitrogen Problem: Why Global Warming Is Making It Worse

By Richard Conniff Photo: NASA/NOAA

New research shows that increases in rainfall and extreme weather because of climate change will increase the amount of nitrogen polluting rivers and other waterways. The findings underscore the urgency of reforming agriculture to dramatically reduce the use of nitrogen fertilizers.
