Greenhouse Gases and Atmospheric Composition

Climate change primarily arises from the increased presence of greenhouse gases (GHGs) in the atmosphere. Activities like burning fossil fuels, deforestation, and industrial processes release substantial amounts of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) into the atmosphere.

Greenhouse Gas	Sources	Atmospheric Lifetime
Carbon Dioxide (CO2)	Fossil fuel combustion, deforestation	100-300 years
Methane (CH4)	Agriculture, landfills, wetlands	12 years
Nitrous Oxide (N2O)	Fertilizers, industrial processes	114 years

These GHGs trap heat in the atmosphere, leading to a gradual increase in global temperatures. Consequently, the Earth’s atmosphere has been warming steadily over the past century, with the rate of warming accelerating in recent decades.

Temperature and Circulation Patterns

The warming atmosphere affects global circulation patterns, including wind and precipitation patterns, resulting in more frequent and intense extreme weather events. For instance:

Rising temperatures increase the evaporation rate of water from oceans and land surfaces, leading to increased atmospheric moisture and more frequent and intense precipitation events.
The warming atmosphere also affects the temperature gradients between different regions, influencing wind patterns and the frequency and intensity of storms.
