Cultural burning is better for Australian soils than prescribed burning, or no burning at all

What does fire management do to soils? We compared prescribed burning to cultural burning and looked at how soil properties changed after fire. Cultural burning was better.

The world’s boreal forests may be shrinking as climate change pushes them northward

How will Earth’s vast boreal forests look in a warmer world? Combining satellite-based research with fieldwork shows that the planet’s largest wilderness may be changing in unexpected ways.

Here’s how to fix Australia’s approach to soil carbon credits so they really count towards our climate goals

A group of agricultural and soil scientists has serious concerns about the way credits are awarded for soil carbon sequestration in Australia.

A hundred years of logging threatens the Innu link to their land

The Biden administration has called for protecting mature US forests to slow climate change, but it’s still allowing them to be logged

Protecting old and mature trees is the simplest and least expensive way to pull carbon out of the atmosphere – but proposed logging projects threaten mature stands across the US.

We helped fill a major climate change knowledge gap, thanks to 130,000-year-old sediment in Sydney lakes

80% of carbon on land in stored in soil. Our new research investigated how erosion transports this carbon to the bottom of lakes, where it’ll never be released into the atmosphere.

Very hungry caterpillars can have large effects on lake quality and carbon emissions

As environmental engineers, invasive caterpillars can have remarkable effects on water quality and soil conditions. But from a climate perspective they’re pretty much a nuisance.

Forests can’t handle all the net-zero emissions plans – companies and countries expect nature to offset too much carbon

Yes, trees and soils can absorb and store carbon, but the carbon doesn’t stay stored forever. That’s one of the problems with how net-zero plans for the climate are being designed.

Food production generates more than a third of manmade greenhouse gas emissions – a new framework tells us how much comes from crops, countries and regions

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.

Organic food has become mainstream but still has room to grow

Four out of five Americans regularly buy some kind of organic food. An expert on the industry says more federal support could greatly expand organic farming and its environmental benefits.
