A rather straightforward calculation showed that doubling the level of carbon dioxide in the atmosphere... which would arrive in the late 21st century if no steps were taken to curb emissions... should raise the temperature of the surface roughly one degree C. However, a warmer atmosphere would hold more water vapor, which ought to cause another degree or so of warming.

The Red Planet's thin atmosphere of carbon dioxide can't retain enough heat for water to flow on the planet, but new calculations suggest how it was once warmer

Higher lake temperatures may speed the conversion of carbon - rich organic matter in lake sediments into methane and carbon dioxide, gases that once released into the atmosphere could exacerbate global warming.

Bowen says the two relatively rapid carbon releases (about 1,500 years each) are more consistent with warming oceans or an undersea landslide triggering the melting of frozen methane on the seafloor and large emissions to the atmosphere, where it became carbon dioxide within decades.

But some of that heat gets blocked by those pesky carbon dioxide molecules building up in the atmosphere — inexorably warming our planet.

Researchers are pursuing a handful of negative emissions technologies (NETs) that would mitigate global warming by pulling carbon dioxide (CO2) out of the atmosphere.

Their results suggest a drop of as much as 10 degrees for fresh water during the warm season and 6 degrees for the atmosphere in the North Atlantic, giving further evidence that the concentration of atmospheric carbon dioxide and Earth's surface temperature are inextricably linked.

They dramatically accelerated the natural breakdown of exposed rocks, according to a new study, drawing so much planet - warming carbon dioxide (CO2) from the atmosphere that they sent Earth's climate spiraling into a major ice age.

If carbon dioxide makes up only a minute portion of the atmosphere, how can global warming be traced to it?

The warming climate threatens to thaw permafrost, which will result in the release of carbon dioxide and methane into the atmosphere creating feedbacks to climate change — more warming and greater permafrost thaw.

Short - lived climate pollutants are so called because even though they warm the planet more efficiently than carbon dioxide, they only remain in the atmosphere for a period of weeks to roughly a decade whereas carbon dioxide molecules remain in the atmosphere for a century or more.
