A new study provides a detailed way to calculate the climate impact of food production, which could lead to more sustainable farming policies and methods.
Farmers can help slow climate change by mixing native grasses into croplands, restoring wetlands and raising perennial crops. These strategies also conserve soil and water and build new markets.
If we had not altered the composition of the atmosphere at all through emitting greenhouse gases, particulate matter and ozone-destroying chemicals, the average temperature would have remained stable.

Globally, emissions from air travel account for only about 3% of the warming human activities are causing, but aviation affects our climate in a number of ways.
Measurements and modelling have found nitrous oxide emissions, a greenhouse gas 265 times more potent than carbon dioxide, are significantly higher than previously reported.
Media-driven panic about drugs can create a perception more people are using the drug than they actually are, and when teens think ‘everyone’ is doing it, they are more likely to want to do it too.
Global greenhouse gas levels have hit their highest point in at least 3 million years, according to new figures from the World Meteorological Organisation.
