The National Oceanic and Atmospheric Administration says the levels of the crucial heat-trapping gases in the atmosphere reached historic highs last year, growing at near-record fast paces.
Re: "This is not to say methane can be ignored - reducing methane levels is definitely a goal to pursue. The good news is since the early 1990's, the trend in increasing methane has slowed down and even leveled off in the last few years (Dlugokencky 2003)." Gee, what a coincidence...

and that data would come back to the utility in close to real time,” he said. “Over the last 10 years, the technology improvements in leak survey have accelerated. I would expect that
Image: Extracted ice cores that contain air bubbles can help researchers understand how methane levels in the atmosphere have changed over time. Why and how do orphaned wells emit methane into the surrounding environment? Without proper maintenance, orphaned wells and other abandoned oil and natural ...
Of particular concern is the surge in methane (CH4), a planet-heating gas 70-80 times more powerful than carbon dioxide (CO2) over the short run. Figure 1. World atmospheric methane levels are rising steeply. Source: NOAA 2024. Image: Supplied In recent years, methane levels in the worl...
Methane (CH4), a powerful greenhouse gas with a global warming potential > 27 times greater than that of carbon dioxide over 100 years1, plays a crucial role in the global carbon cycle2. Emissions of methane from the ocean to the atmosphere are estimated to be 6–12 Tg yr−13, account...
new research led by Drexel University finds that atmospheric methane levels in the area are still increasing. Measurements of methane and other air pollutants taken three years apart in the rural areas of Pennsylvania that have been the target of natural gas development over the last decade, reveal...
gases caused by humans, rose in 2023 by the third highest amount in 65 years of record keeping, NOAA announced Friday. Scientists are also worried about the rapid rise in atmospheric levels of methane, a shorter-lived but more potent heat-trapping gas. Both j...
