Nitrous oxide is a potent greenhouse gas, 300 times more powerful than carbon dioxide. Global emissions of N2O are on the rise as a result of human activities — and their impact on ocean ecosystems.

New research indicates that people in urban areas, on average, have the smallest carbon footprints, and those living in the suburbs the highest.
For Indigenous people, Country is more than a landscape. But climate change, and the natural disasters it produces, present a clear and present threat to Country, culture and heritage.
Structures are built to withstand a normal range of conditions. But what’s ‘normal’ is changing rapidly.
Rain near Japan triggered a heat wave in North America. To know our future, we have a lot to learn about what drives extreme weather.
Researchers found 16% of coral species have not been seen for many years. This finding is alarming, because local extinctions suggest global extinctions may be looming.
It’s no coincidence that more books about trees are popping up. There is an air of desperation in new books by Peter Wohllben, Janine Burke and others.
Federal environment minister Sussan Ley wrote an opinion article saying the reef didn’t deserve to be the poster child for climate change perils. We disagree.
Given the scale of the problem, five years was never enough time to turn things around. Clearly, we must reflect honestly on our successes and failures so far.
New normal. Record-breaking. Unprecedented. In recent days, as Western Canada and the United States have been broiling under a climate-fuelled heat crisis, all sorts of superlatives have been used to describe…
Solve the climate and extinction crises together, or solve neither.
Every year, the number of wildfires caused by humans spikes on Independence Day. There are safer ways to celebrate amid the heat and drought.
Policymakers want to pay farmers for storing carbon in soil, but there are no uniform rules yet for measuring, reporting or verifying the results. Four scholars offer some ground rules.
Converting food waste to animal feed – or reducing it altogether by supermarkets working with farmers – could save millions of tonnes of food from being discarded. It could also help raise animal welfare standards.
Dams built in an earlier age are suddenly vulnerable as the climate shifts.
Without enough water, trees can develop embolisms, similar to blockages in human blood vessels, and they’re more likely to die from drought or fires.
The IPCC’s review process is among the most exhaustive for any scientific process. Each report generates thousands of comments from hundreds of reviewers across a range of scientific perspectives.
The fact that nearly half the world’s population is still struggling to escape poverty while global temperatures hurtle upward is not a coincidence.
The world’s nuclear power plants are on the frontline of climate change – and not in a good way.
If problems in such schemes are not addressed, the credibility of soil carbon trading will be undermined. Ultimately the climate - and the planet - will be the loser.
