The most notorious greenhouse gas is carbon dioxide (CO2) Carbon dioxide is part of the natural cycle that keeps Earth liveable. It helps to act like a blanket, trapping heat to keep temperatures ...

Carbon dioxide is a greenhouse gas, one of the four main ones. In terms of US greenhouse gas emissions, here's a list by amounts from the Environmental Protection Agency: Carbon dioxide, 79%.

Carbon dioxide, CO2, accounts for about two-thirds of the warming attributed to greenhouse gases, said Piers Forster, an expert at the University of Leeds and author of reports by the IPCC, the UN ...

The claim: CO2 from humans represents 3.2% of total CO2 in the atmosphere and 0.12% of all greenhouse gases in the atmosphere. A June 14 Facebook post (direct link, archive link) uses pie charts ...

Nitrogen (78%) and oxygen (21%) make up the bulk of the atmosphere with trace amounts of what are termed greenhouse gases, primarily comprised of water vapor, carbon dioxide (CO2,) methane (CH4 ...

A team of 60 international scientists report that by early 2028 society will have emitted enough greenhouse gases that the ...

Carbon dioxide is not the only greenhouse gas under fire at the COP28 climate summit in Dubai, United Arab Emirates. On 2 December, the UAE, the US and China are convening other countries for a ...

The carbon dioxide we emit today will continue warming our planet for up to 100,000 years, but methane only lasts for a timescale of 12 years before breaking down into less potent gases.

I couldn’t in good conscience put together a list of greenhouse gases and not at least mention the big one. Human activities released 37.4 billion tons of carbon dioxide into the atmosphere in 2023.

Carbon dioxide made up most of the greenhouse gas emissions in 2023, at nearly 80%, according to the report. This is consistent with data dating back to 1990. The U.S. does not set individual ...

These gases are a major concern because, though they currently only represent around 2 per cent of total greenhouse gases, their GWP is tens of thousands of times greater than carbon dioxide.
