John Tyndall set the foundation for our modern understanding of the greenhouse effect, climate change, meteorology, and weather. But did he ‘discover’ it? On 18 May 1859, the Irish physicist John Tyndall wrote in his journal ‘the subject is completely in my hands’.
Is co2 a greenhouse gas?Greenhouse gases include carbon dioxide, methane, nitrous oxide and other gases that accumulate in the atmosphere and create the heat-reflective layer that keeps the Earth at a livable temperature. These gases form the insulation that keeps the planet warm enough to support life.
Greenhouse gases The main driver of climate change is the greenhouse effect. Some gases in the Earth’s atmosphere act a bit like the glass in a greenhouse, trapping the sun’s heat and stopping it from leaking back into space and causing global warming.
The greenhouse effect is a process in which the temperature of the Earth’s surface increases. When the sun’s energy reaches the earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases, like carbon dioxide, methane, nitrous oxide, ozone etc.
Greenhouse gases’ are crucial to keeping our planet at a suitable temperature for life. Without the natural greenhouse effect, the heat emitted by the Earth would simply pass outwards from the Earth’s surface into space and the Earth would have an average temperature of about -20°C.
In the United States, most of the emissions of human-caused (anthropogenic) greenhouse gases (GHG) come primarily from burning fossil fuels—coal, natural gas, and petroleum—for energy use.
Several major greenhouse gases that result from human activity are included in U.S. and international estimates of greenhouse gas emissions: Carbon dioxide (CO2) Methane (CH4) Nitrous oxide (N2O) Industrial gases: Hydrofluorocarbons (HFCs) Perfluorocarbons (PFCs) Sulfur hexafluoride (SF6) Nitrogen trifluoride (NF3)

The process is called the greenhouse effect because the exchange of incoming and outgoing radiation that warms the planet works in a similar way to a greenhouse. Picture this: a greenhouse is so successful at growing plants year-round, even when it’s too cold outside for some plants to typically thrive.
Global Warming Potential (100-year): 1 Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2020, CO2 accounted for about 79% of all U.S. greenhouse gas emissions from human activities.
