#COP26: As #carbon #emissions rise unabated, scientists eye a #methane removal fix

(we are doomed LOL 🤣)

• The COP26 climate summit has moved into its second week, with no major climate change breakthroughs in sight. Just as alarming is a new investigation released today by The Washington Post showing that the world’s nations are hugely underreporting carbon emissions, making the race to truly curb carbon emissions even more urgent.
• As a result, COP26 negotiators and scientists are shifting their immediate attention from not only cutting CO2 emissions, but also slashing methane (CH4) emissions from fossil fuel, agricultural, and landfill sources. A hundred nations last week pledged to reduce methane emissions by 30% by 2030.
• Some scientists think they know the answer, suggesting a variety of engineering solutions to achieve rapid methane removal from the atmosphere — solutions which have been successful in the lab but remain untested in nature. COP26 attendees are said to be showing significant interest in this potential technology fix.
• However, there are numerous concerns, including the possible unforeseen public health and environmental impacts of methane removal technology, the challenge of upscaling and implementing the various proposed methods, and finding funding for the work. Perhaps the biggest hurdle is time, as climate change escalates apace.

GLASGOW, Scotland — Carbon dioxide emissions from energy and transportation have long taken center stage at United Nations climate summit negotiations. But here at COP26, in cold, rainy Scotland, methane, a far more potent heat-trapping gas, is grabbing a share of the spotlight for the first time.

With good reason.

Methane only exists at roughly 2 parts per million in the atmosphere, compared to 412 parts per million for CO2. But the methane molecule (CH4) traps as much as 85 times more heat than the more abundant polluting CO2. But while carbon dioxide remains in the sky like a warming blanket for hundreds of years, methane largely dissipates in roughly a decade — making it a ripe target for nations to attack in their effort to slow the ominous quickening pace of global warming.
