Could our best shot at stopping climate catastrophe be restoring forests on a massive scale?
A sperm whale goes down for a dive off Kaikoura, New Zealand.
Protecting forests and wetlands, which absorb and store carbon, is one way to slow climate change. Scientists are proposing similar treatment for marine animals that help store carbon in the oceans.
Two driverless tractors spray vines in a Texas vineyard. Each one is controlled from a single command station (2012).
Digital innovations have the potential to empower farmers and revolutionise agriculture, but many could also lock them in to unsustainable methods.
Marshes at Blackwater National Wildlife Refuge on Maryland’s Eastern Shore.
Marshes, swamps and other kinds of wetlands provide valuable services, such as effective natural flood control. But they are being destroyed for development in many parts of the world.
Tiny chemical clues in the ocean reveal how its role as a carbon store is changing.
Mangrove forest in Pichavaram, Tamil Nadu, India.
Mangrove forests along the world's tropical and subtropical coasts store enormous quantities of 'blue' carbon – especially in river delta zones, where soil builds up quickly.
Over 99 percent of today’s plastics come from oil, but new bio-based options are becoming available.

One big problem with plastics is that they're largely made of petroleum. Sourcing bio-polymers from plants and bacteria has some big benefits – and the technology is starting to take off.
Opportunities to help drive the energy transition are everywhere - even in Western Australia’s remote salt pans.
Peter C. Doherty
Nobel Prizewinning health researcher Peter Doherty reflects on the challenge of delivering a healthy climate for the world. From hydrogen power to wooden skyscrapers, the options are endless, but all require leadership.

Wetlands are some of the world's most undervalued weapons against climate change. They store huge quantities of carbon – but without better protection, many could soon be drained or paved over.
Long’s Peak framed by rock outcrop, Rocky Mountain National Park, Colorado.
Scientists have long thought most nitrogen in Earth's ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.
Europe loses as many trees to storms each year as Poland produces in timber. Until now, the models for predicting which trees are at risk have not been good enough.
Giant kelp can grow up to 60cm a day, given the right conditions.
In an extract from his new book, Tim Flannery explains how giant kelp farms could suck carbon dioxide from the air and store it in the ocean's depths, while encouraging species like fish and oysters.
A coolabah forest in Western Australia – one of the world’s previously unrecognised dryland forests.
A new survey has identified millions of hectares of forest in dryland areas, a finding that boosts the total global forest cover by 9% and has significant consequences for carbon budgets.
Cypress swamp near Mandeville, Louisiana.
A new report calls U.S. forests an undervalued asset for slowing climate change. It warns that they are being degraded by logging for wood, paper and fuel, particularly in the Southeast.
Iceland’s geothermal power plants are an ideal place to test pumping carbon dioxide underground.
An Icelandic trial shows carbon dioxide can be pumped underground and stored as rock.

Study shows mangrove forests along desert coasts have potential to lock up large amounts of carbon and buffer against rising seas.
Sea turtles eating more seagrass could threaten the ocean’s ability to store carbon.
Sharks and other ocean predators help protect the ocean's carbon stores by keeping other wildlife in check.
Lush rainforest above ground… spare a thought for what’s happening in the soil.
It’s no exaggeration to say the tropics drive our planet’s carbon cycle – the constant transfer of carbon back and forth, on a global scale, between living things and the environment. Understanding the…
Coal seam gas is only one issue for managing one of Australia’s most important geological resources.

In a recent article on The Conversation, Queensland coal seam gas (CSG) researchers argued that the industry is progressing faster than the science, leading to concerns over fugitive emissions and impacts…

The concept of a “tipping point” – a threshold beyond which a system shifts to a new state – is becoming a familiar one in discussions of the climate. Examples of tipping points are everywhere: a glass…
