Carbon dioxide, methane and nitrous oxide reached record-high concentrations in the atmosphere in 2021, including the largest recorded increase in methane Environment 26 October 2022 By James Dinneen Greenhouse gas emissions are still rising Shutterstock/engel.ac Carbon dioxide, nitrous oxide and methane reached record high concentrations in the atmosphere in 2021 and have continued to rise...
Atmospheric levels of all three greenhouse gases have reached record highs, according to a study by the World Meteorological Organization, which scientists say means the world is “heading in the wrong direction”. The WMO found there was the biggest year-on-year jump in methane concentrations in 2020 and 2021 since systematic measurements began almost 40 years...
GENEVA — The three main greenhouse gases hit record high levels in the atmosphere last year, the U.N. weather agency said Wednesday, calling it an “ominous” sign as war in Ukraine, rising costs of food and fuel, and other worries have elbowed in on longtime concerns about global warming in recent months. “More bad news...
Pledges to cut greenhouse gas emissions will lead to global heating of 2.5C, a level that would condemn the world to catastrophic climate breakdown, according to the United Nations. Only a handful of countries have strengthened their commitments substantially in the last year, despite having promised to do so at the Cop26 UN climate summit...
A pond covered in duckweed. Credit: Joseph Rabaey, University of Minnesota Plants typically absorb carbon dioxide and release oxygen as part of photosynthesis. Most people associate greenery with reduced carbon levels, and in the case of Minnesota’s trees, that is certainly true. But in the thousands of duckweed-covered ponds across the state, the reality is...
Methane is a much more potent greenhouse gas than carbon dioxide, trapping heat 80 times more effectively over a 20-year period. The amount of methane in the atmosphere is two and a half times pre-industrial levels and increasing steadily. There is little hope of keeping below the 1.5C target unless methane emissions are drastically reduced...

In a world-first, New Zealand appears set to introduce a scheme that will require farmers to pay for their agricultural greenhouse gas emissions, including the methane belched out by cows and nitrous oxide emitted through livestock urine. The prime minister, Jacinda Ardern, and three of her ministers, stood behind a podium of hay bales at...
Costing the Earth? Beef is the worst offending food when it comes to greenhouse gas emissions. (Photo by Saul Loeb/AFP via Getty Images) Land use and farm activities are shown by a study to be a significant source of food-related greenhouse gas (GHG) emissions. In the largest analysis of data of global food systems to date, published...
