Description of the problem

The causes of climate change are pollution, destroying of the wood, aerosols, radiation from sun and fire in the forests which was made accidentally. Because of pollution we are under the effect of global warming, Air is polluted, so the air which is under the polluted layer cannot give its temperature to vacuum. But at the same time sun makes this air more and warmer. When the trees are destroyed, there are a lot of CO2 and no photosynthesis, so the climate balance between CO2 and oxygen begin to break. Radiation from sun comes to the earth through the holes in ozone layers. It has a lot of bad effects, so we need to control our industry and prevent weakening of our ozone layer. Different aerosols make it weaker and weaker and it is really bad. Greenhouse effect is near. Here is what it is:

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be in the absence of its atmosphere. If a planet's atmosphere contains radioactively active gases (i.e., greenhouse gases) the atmosphere radiates energy in all directions. Part of this radiation is directed towards the surface, warming it.

On Earth, solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface. The surface itself emits energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases in the atmosphere. These gases also radiate energy, some of which is directed to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection.

If an ideal thermally conductive blackbody were the same distance from the Sun as the Earth is, it would have a temperature of about 5.3 °C. However, since the Earth reflects about 30% of the incoming sunlight, this idealized planet's effective temperature (the temperature of a blackbody that would emit the same amount of radiation) would be about −18 °C. The surface temperature of this hypothetical planet is 33 °C below Earth's actual surface temperature of approximately 14 °C. The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect.

E arth’s natural greenhouse effect is critical to supporting life. Human activities, primarily the burning of fossil fuels and clearing of forests, have intensified the natural greenhouse effect, causing global warming.

Climate change affects all regions around the world. Polar ice shields are melting and the sea is rising. In some regions extreme weather events and rainfall are becoming more common while others are experiencing more extreme heat waves and droughts.

These impacts are expected to intensify in the coming decades.
