On Earth, carbon dioxide is the most relevant, direct greenhouse gas that is influenced by human activities. Water is responsible for most (about 36–70%) of the total greenhouse effect, and the role of water vapor as a greenhouse gas depends on temperature. Carbon dioxide is often mentioned in the context of its increased influence as a ...
Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
Metronome in November 2020, after the original clock was replaced with the Climate Clock. The Climate Clock is a graphic to demonstrate how quickly the planet is approaching 1.5 °C of global warming, given current emissions trends. [1]
Climate 101 is a Mashable series that answers provoking and salient questions about Earth’s warming climate. The last time CO2 levels were as high as today, ocean waters drowned the lands where ...
An alarming new report from the Scripps Institution of Oceanography shows a record-breaking amount of CO2 in our atmosphere. According to NBC, the new tests show the level of carbon dioxide, a ...
We’ve entered some profoundly unfamiliar planetary territory. Amid a backdrop of U.S. politicians still questioning whether the changing climate is attributable to humans (it is), it's quite ...
In 2016, the global average temperature was already 1.1°C above pre-industrial levels. [15] According to the review of the scientific literature conducted by the Intergovernmental Panel on Climate Change (IPCC), carbon dioxide is the most important anthropogenic greenhouse gas by warming contribution.

Total atmospheric mass is 5.1480 × 10 18 kg (1.13494 × 10 19 lb), [36] about 2.5% less than would be inferred from the average sea-level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain. Atmospheric pressure is the total weight of the air above unit area at the point where the ...
