Ice cores suggest natural seeps release less methane than was estimated, meaning industry produces nearly all of today’s geologic methane emissions.

"Global methane emissions increased from about 499 teragrams (Tg) to 550 Tg during the period from 2010 to 2019, followed by a surge to 570—590 Tg between 2020 and 2022." ...

The amount of methane in the Earth’s atmosphere has been increasing by around 25 teragrams each year since 2006 -- which, NASA notes, is about the weight of a whopping 425,000 elephants ...

“Our concern is that the subsea permafrost has been showing signs of destabilization already,” says Shakhova. “If it further destabilizes, the methane emissions may not be teragrams, it ...

Currently, all the cows on Earth create 75 Teragrams (over 165 billion pounds) of methane emissions annually, which is a lot of cow burp/fart related greenhouse gas. This may be why British ...

The final value they came to (again, 2-8 teragrams of carbon dioxide produced per year) includes some uncertainty because data on dredging and trawling is limited, the ocean floor isn’t uniform ...

Previous estimates performed for the ESAS suggested that the area was releasing 8 teragrams of methane into the atmosphere yearly.

By 2050, roughly 15 teragrams of dissolved organic carbon is due to be released into waterways from melting glaciers, the team estimates.

It is also five times more than Canada’s total annual emissions, and comparable to India, which emitted 740 teragrams of carbon last year.

That would bring worldwide emissions to more than 77 teragrams, she adds. NO x compounds substantially contribute to acid rain, which is increasing in eastern Asia.

Specifically, the research team found that 70.5 million tons (64 teragrams) of foreign aerosols — which include naturally occurring dust as well as pollution — arrive over North America every ...

Eight teragrams of anything, let alone a heat-trapping greenhouse gas, sounds dangerous, but as Martin Heimann of the Max Planck Institute for Biogeochemistry in Jena, Germany, points out, the ...
