Methane is a potent greenhouse gas that can leak from oil and gas wells, pipelines and landfills. Satellites can spot the releases fast enough to get them fixed and help protect the climate.

Scientists found PFAS hot spots in Miami’s Biscayne Bay where the chemicals are entering coastal waters and reaching the ocean. Water samples point to some specific sources.
For Australia to shift to a net zero economy, its big polluters need to cut emissions. A get-out clause buried in the policy makes it unlikely that they will, and the result will be devastating.
PFAS can be filtered, but getting rid of the chemicals is a monumental challenge. A biochemist and soil scientist explain.

Most food waste still goes into red bins of mixed waste bound for landfill. It’s using up precious landfill space and harming the environment when it could produce valuable compost and biogas instead.

Reducing food waste at home is an action that anyone can take to help slow climate change, often saving money in the process. More consumer education could help show people what to do.

The complexity of construction projects has driven an increase in building waste, which is difficult to recycle and reuse. But there are ways to minimise the problem.
How long do we really need chemicals to last?

Killer whales among the animals at risk from a ‘second wave’ of pollutants, as coasts erode and sea levels rise.
Methane is the world’s second most abundant greenhouse gas. It doesn’t stay in the atmosphere as long as CO2, but it’s many times more potent.

The lead author of a new UN report on methane explains the findings and how oil and gas companies could be making money and saving the climate at the same time.
