How to rewild your garden and create a tiny rainforest

Many scientists believe that halting global warming at 1.5°C will require us to invent Negative Emission Technologies – machines that can suck climate warming gases like carbon dioxide (CO₂) from the air. But such technology already exists and has done for over two billion years.

‘Asia undermining efforts to reduce coal dependence,’ says UN

Asia’s dependence on coal is completely at odds with the Paris Agreement to combat climate change, a UN official has warned, as experts from the region met in Bangkok to find ways to intensify efforts to stem global warming.

African countries and the state of their environments: the best and the worst

Social and economic changes in Africa are being driven by increasing prosperity and heavy foreign investment. Money has been poured into activities such as road building, forestry expansion, livestock intensification and increasing urbanisation. All have increased pressure on the continent’s environment.

How did elephants evolve such a large brain? Climate change is part of the answer

Elephants have long captivated our attention, partly because of their sheer size and majesty. But we’re also struck by their complex behaviour. In some ways, we’re fascinated because this behaviour echoes our most humane feelings. For instance, elephants have repeatedly been observed using tools and grieving their dead.

Methane emissions from oil and gas exploration are under-reported

Wetlands in Canada’s boreal forest contain deep deposits of carbon-rich soils, made up of decomposed vegetation (peat) that has accumulated over thousands of years. Globally, peatlands store twice as much carbon as all of the world’s forests combined. Protecting this carbon store is critical in the fight against climate change.
