Feb 25, 2021 As carbon dioxide and other greenhouse gases heat up the planet, more water evaporates into the atmosphere, which in turn raises the temperature further. However, a hypothetical villain would not be able to exacerbate climate change by trying to pump more water vapor into the atmosphere, says Smerdon.
(more) Of the greenhouse gases, carbon dioxide (CO 2) is the most significant. Natural sources of atmospheric CO 2 include outgassing from volcanoes, the combustion and natural decay of organic matter, and respiration by aerobic (oxygen-using) organisms.
Oct 9, 2019 Credit: Public domain. By volume, the dry air in Earths atmosphere is about 78.08 percent nitrogen, 20.95 percent oxygen, and 0.93 percent argon. A brew of trace gases accounts for the other approximately 0.04 percent, including the greenhouse gases carbon dioxide, methane, nitrous oxide and ozone.
Aug 9, 2021 The report shows that emissions of greenhouse gases from human activities are responsible for approximately 1.1C of warming since 1850-1900, and finds that averaged over the next 20 years, global temperature is expected to reach or exceed 1.5C of warming.
Dec 14, 2023 english. Timeplot of increase of atmospheric carbon dioxide (CO) concentrations relative to the pre-industrial CO long-term mean value of 278 ppm. During 2021, atmospheric CO concentrations reached a record-level increase of 50% relative to pre-industrial CO levels. Credit: NASA.
The first graph shows atmospheric carbon dioxide (CO 2) levels measured by NOAA at Mauna Loa Observatory, Hawaii, since 1958. Since the onset of industrial times in the 18 th century, human activities have raised atmospheric CO 2 by 50% meaning the amount of CO 2 is now 150% of its value in 1750.

The long-term trend of rising carbon dioxide levels is driven by human activities. At Mauna Loa, the highest monthly value each year occurs in May. In May 2023, carbon dioxide hit 424 ppma new record. NOAA Climate.gov image, based on Mauna Loa monthly mean data from NOAA Global Monitoring Lab.
Takeaways. The greenhouse effect is essential to life on Earth, but human-made emissions in the atmosphere are trapping and slowing heat loss to space. Five key greenhouse gases are carbon dioxide, nitrous oxide, methane, chlorofluorocarbons, and water vapor.
Jun 7, 2021 The amount of carbon dioxide in Earth's atmosphere reached 419 parts per million in May, its highest level in more than four million years, according to NOAA. Fossil fuel use is driving the...

Jun 15, 2017 Climate Change & Global Warming October 12, 2022. Fossil fuels are the only source of carbon dioxide large enough to raise atmospheric carbon dioxide amounts so high so quickly. First saildrone circumnavigates Antarctica, seeking carbon dioxide. Observing & Predicting August 22, 2019.
Carbon dioxide emissions are the primary driver of global climate change. It's widely recognized that to avoid the worst impacts of climate change, the world needs to urgently reduce emissions. But, how this responsibility is shared between regions, countries, and individuals has been an endless point of contention in international discussions.

Climate Impact of Increasing Atmospheric Carbon Dioxide | Science. Science. 28 Aug 1981. Vol 213, Issue 4511. pp. 957 - 966. DOI: 10.1126/science.213.4511.957. Abstract. The global temperature rose by 0.2C between the middle 1960's and 1980, yielding a warming of 0.4C in the past century.
2 days ago How to siphon carbon from the seas. Earths oceans naturally concentrate carbon dioxide (C0 2) from the atmosphere. To extract it, Captura, a California startup, uses renewable electricity to change the water chemistry. The CO 2 bubbles out and is then captured and stored beneath the seabed.
2 days ago DOI: 10.1038/s41612-024-00619-z. New Curtin University research has shown the warming climate will turn Australia's soil into a net emitter of carbon dioxide (CO 2 ), unless action is taken. "A ...
Nov 15, 2022 Global carbon dioxide emissions in 2022 remain at record levels and natural carbon sinks are being impacted by climate change, according to a new report. Experts from NOAA and elsewhere project that atmospheric carbon dioxide concentrations will reach an average of 417.2 parts per million in 2022.
The planet's average surface temperature has risen about 2 degrees Fahrenheit (1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide emissions into the atmosphere and other human activities. 4 Most of the warming occurred in the past 40 years, with the seven most recent years being the warmest.
Jul 14, 2016 The average amount of carbon dioxide in Earths global atmosphere is 400 parts per million (ppm), but according to Ken Davis, Atmospheric Carbon and Transport - America (ACT-America) principal investigator, areas near agriculture like cornfields can consistently run about 10 ppm lower in the summertime.

Carbon monoxide (which comes from unvented heaters and generators and other gasoline-powered equipment) affects methane, carbon dioxide and ozone levels in the atmosphere. Because carbon monoxide lingers in the air for about a month it can travel long distances, making it useful for studying how air pollution moves around the world.
