Last month, the Intergovernmental Panel on Climate Change, made up of the world’s leading climate scientists, delivered a “final warning” on rising greenhouse gas emissions that have pushed the world to the brink of irrevocable damage that only swift and drastic action can avert. Scientists have been warning of catastrophic consequences for decades, yet meaningful climate action to cut fossil fuel use and other harmful human activities has been delayed and blocked, in large part due to the influence of industries such as oil and gas, agriculture, defence and automobiles. “The time is now to address greenhouse gas pollution and to lower human-caused emissions as we continue to build toward a Climate-Ready Nation.” “The observations collected by Noaa scientists in 2022 show that greenhouse gas emissions continue to rise at an alarming pace and will persist in the atmosphere for thousands of years,” said Rick Spinrad, the Noaa administrator. But the primary culprits behind rising nitrous oxide levels in recent decades have been synthetic fertilisers and livestock manure from industrialised agriculture. Levels of nitrous oxide, the third-most significant anthropogenic greenhouse gas, are now 24% higher than pre–industrial levels, following a 1.25ppb rise last year.įossil fuel-powered vehicles (cars, buses, trucks, farm machinery) are a major source of nitrous oxide, which is harmful to human health and water sources. The oil and gas sector is the largest industrial source of methane, which can also cause medical complications, fires and even engine failure leading helicopters to fall out of the sky. Methane levels in the atmosphere are now more than two and a half times their pre-industrial level. Methane is a potent greenhouse gas less abundant than CO 2 but which warms the Earth’s atmosphere much faster, and today is responsible for about 25% of the heat trapped by all greenhouse gases. In July, a US-Australian cybersecurity firm, Internet 2.0, published a report in which it said data collection on the app was overly intrusive and flagged a connection in the app to a server in. The 2022 methane rise was the fourth-largest since records began in 1983, following record growth in 20, and now stands at an average of 1,912 parts per billion (ppb). Before 2013, scientists had never recorded three consecutive years of such high CO 2 growth.Ītmospheric CO 2 is now 50% higher than pre-industrial levels. Atmospheric levels of carbon dioxide (CO 2), methane and nitrous oxide – the greenhouse gases emitted by human activity that are the most significant contributors to global heating – continued to increase rapidly during 2022, according to the National Oceanic and Atmospheric Administration (Noaa).Ĭarbon dioxide levels rose by more than two parts per million (ppm) for the 11th consecutive year: the highest sustained rate of CO 2 increases since monitoring began 65 years ago.
