Greenhouse Gas Emissions

The health benefits of a meat-based versus a plant-based diet are often hotly debated. A new study adds another checkmark to the plant-based column though, as it loops in the environmental impacts of choosing paleo or keto diets over veganism.

While crops do sequester some atmospheric carbon dioxide (CO2) via photosynthesis, they could always use a bit of help. California startup Andes is aiming to provide that help, by putting carbon-capturing microbes in the soil of farmers' fields.

Researchers have identified 27 feedback loops demonstrating how one effect of climbing temperatures leads to events that further reinforce global warming and the initial event itself. The findings make immediate climate action even more crucial.

Make all the jokes you want, but the methane emitted in the form of cow burps and farts is actually a major source of greenhouse gas emissions. That could soon change, however, thanks to bacteria found in baby kangaroo feces.

Atmospheric dust can both cool and warm our planet. A new study shows that this dust could be masking the true impact of greenhouse gasses on climate change, and that a shift in the dust quantity could lead to a warming spike.

By using a labeling system, a research team found that it was possible to shift dining choices away from climate-straining red meat consumption and towards more eco-friendly plant-based options.

Hydrogen will be one of humanity's key weapons in the war against carbon dioxide emissions, but it must be treated with care. New reports show how fugitive hydrogen emissions can indirectly produce warming effects 11 times worse than those of CO2.

Carbon dioxide may hog headlines as a climate change villain, but methane is a far more potent greenhouse gas. MIT has now demonstrated a new way to remove methane from the air, even at low concentrations, with a common clay used to make cat litter.

Nitrous oxide is a potent greenhouse gas – and now it looks like we may have underestimated how much is being released. A new study has identified the thawing Siberian permafrost as a huge, previously unknown source of nitrous oxide emissions.

You'll be hearing a lot more about ammonia as a clean fuel option in the race to zero carbon by 2050. In particular, it looks like a strong option for long-haul ships and trucks. So what is it, how is it made, and how does it shape up as green fuel?

Climate change can feel inevitable, but we’ve stepped up to the challenge before. New modeling shows how bad things would be if CFCs hadn’t been banned decades ago – depleted ozone would've increased UV exposure and stopped plants capturing carbon.

According to a new report issued by the United Nations' Intergovernmental Panel on Climate Change (IPCC), human-caused climate change will have dire consequences over the next 20 years.
