Methane: What′s the big deal?

With much of the climate conversation centered around cutting carbon dioxide, less attention is paid to a more potent, less common and sometimes smellier greenhouse gas: methane.

Scientists sniff for hidden methane leaks to combat global warming

Methane leaks are the focus of new efforts to slow the pace of global warming. The colourless and odourless gas is an astonishing 84 times more potent in heating our atmosphere than carbon dioxide over a 20 year period.

An expert on oil and gas wells in southwestern Ontario who presented at a national conference outlines the issues with abandoned wells in the wake of an explosion in Wheatley, Ont., that sent seven people to hospital.

Scientists say the world urgently needs to cut methane emissions. The politics aren't as simple.

The Biden administration and some Democrats are shifting focus to methane, the greenhouse gas second-most responsible for heating the planet.

The smokestack of a ship might help us deal with spiking levels of methane.

An ancient era of global warming could hint at our scorching future

Fifty-five million years ago, Earth’s thermostat shot up—and life dramatically changed. Here’s what history can teach us about our modern temperature surge.

Your compostable plastic cups aren't a cure-all

Compostable 'plastic' cups can seem too good to be true, and in many instances they are. But it's probably not for the reasons you think.

Kate Aronoff: Joe Manchin’s lame reason for opposing more infrastructure spending

Voting down the country’s best shot at climate legislation because you’re worried about inflation is pretty twisted.

Cutting methane is the best way to avoid disaster

Although climate change discussions focus mostly on carbon dioxide – the most important greenhouse gas by far – one of the big takeaways from the IPCC report is that to have any hope of staying below 1.5°C of heating we urgently need to cut methane emissions.

For many, hydrogen is the fuel of the future. New research raises doubts

Currently, hydrogen fuel is made from natural gas. But even the cleanest process produces more greenhouse pollution than simply burning the gas, a study has found.
