Climate change caused by human activity

Climate change caused by human activity

Have the mechanisms that govern climate change been properly identified?

The mechanisms that govern climate change have been known for practically two centuries, thanks to the work done by Joseph Fourier in 1824. The intensity of solar radiation (irradiance) reaching the Earth is 1.3 kW per m² on a surface perpendicular to the sun's rays. Roughly one-third of this radiation is reflected back into space by the atmosphere and the ground, while the remaining two-thirds are mainly absorbed by the Earth's landmasses and oceans. The Earth's surface thus absorbs solar energy day after day; it can only stop heating up indefinitely if an amount of energy that is equal to the absorbed energy is released into space. This is achieved by emitting waves of the same nature as the light waves of the sun, but which have a longer wavelength given the much lower temperature of the Earth's surface. These waves correspond to the color infrared, and are also invisible to the human eye. This infrared radiation has to first pass through the atmosphere, where greater the quantity of absorbing gases, the ratio of energy emitted from the Earth's surface to energy released into space. The presence of such gases therefore tends to increase the temperature of the Earth. These gases are said to produce a greenhouse effect by analogy with one of the phenomena that occur in gardeners' greenhouses.

The Earth's atmosphere contains naturally occurring water vapor and carbon dioxide gas (CO2), both of which are greenhouse gases. (more…)
