Scientists are learning trees can emit methane, which could be a big problem for global warming. But a world-first discovery of methane-eating bacteria in paperbark can help moderate this.
Scientists previously underestimated aquatic methane emissions. We must use this new information to stop methane derailing our attempts to stabilise the Earth’s temperature.
A little seaweed with that?
Cow burps and farts are no joke – they're a big factor in climate change. A new study shows that daily seaweed supplements could tame this major methane source while saving ranchers money.
No-one says reducing emissions from the agriculture sector will be easy. But it must be done, or farmers will suffer the most.
Despite the government spruiking a 'gas-led economic recovery', natural gas is clearly on the way out. It's time for a serious rethink on the way many Australians cook and heat our homes.

The end-Triassic mass extinction was a cataclysm for the world's prehistoric species, killed off by volcanoes that altered Earth's seas and skies. But new research shows it didn't happen when we thought.

If so, then the possibility of planetary super-heating in future has just become much more real.

Methane is a live-fast, die-young greenhouse gas but its impact on the climate can last for hundreds or even thousands of years
Investment in gas will not herald Australia's economic recovery. It's likely to hinder it.
Hydrogen is hailed as a new clean fuel, but little attention has been paid to the potential environmental challenges presented by the energy shift.

Such a large accumulation of methane in a lake is unique, and has never been reached in any other lakes.
In Australia, methane emissions from fossil fuels are rising due to expansion of the natural gas industry, whereas agriculture emissions are falling.
Methane bubbles form in a pit digester on a dairy farm as bacteria break down cow manure. The methane can be collected and used as an energy source.

Energy companies are marketing a new fuel: 'renewable' natural gas. But it's not the same from a climate change perspective as wind or solar energy.
If we had not altered the composition of the atmosphere at all through emitting greenhouse gases, particulate matter and ozone-destroying chemicals, the average temperature would have remained stable.

Turning food scraps and yard trimmings into compost improves soil, making it easier for people to grow their own food. City composting programs spread those benefits more widely.
The wet and low-lying East Siberian Arctic is likely to be a major methane source in the coming decades.
Household actions lead to changes in collective behaviour and are an essential part of social movements.
Households generate a large share of national greenhouse gas emissions and can take steps to reduce them.

Two energy scholars who have studied the extent of methane leaks in the oil and gas industry explain what rescinding methane emissions regulations will mean to the climate and industry.
Drones - and other innovative technologies - can be effective in detecting methane leaks.
New technologies can help locate large methane leaks in a faster and more effective manner.
