New research sheds lights on the huge carbon store in Canada’s seabed

New research has revealed the scale of the carbon-storage potential of the seabeds around Canada, conservation efforts must take this new data into account.

Food has a climate problem: Nitrous oxide emissions are accelerating with growing demand for fertilizer and meat – but there are solutions

The most comprehensive assessment yet of a powerful greenhouse gas shows which countries are driving the increase, and which ones are successfully cutting emissions.
Afforestation is one way to offset greenhouse gas emissions. Yet it is not always easy to navigate the different types of projects or methods available, and the possibility of greenwashing is ever-present. (Shutterstock)

Carbon credits are useful for stabilizing the climate, but are they used effectively?

Offsetting greenhouse gas emissions can be an effective tool for limiting global warming. But many offset projects fail to meet their GHG reduction targets.

Climate engineering carries serious national security risks − countries facing extreme heat may try it anyway, and the world needs to be prepared

The big question: Would climate engineering like sending reflective particles into the stratosphere or brightening clouds help reduce the national security risks of climate change or make them worse?
