GLOBAL WARMING AND CLIMATE CHANGE

Today. one of the biggest environmental issues is global warming. Its effects on human population, animals and agriculture will be severe.

I Global warming is the increase in the average temperature of earth's atmosphere and oceans.

II The earth's temperature stays almost the same from year to year. If this average temperature is higher, we have global warming.

Some of the factors that cause global warming isgreenhouse gases.

When we burn wood, coal, or gasoline in our cars, we release a gas called carbon dioxide (C0,). when carbon dioxide in the air goes up, the earth heats up. That is the start of global warming. There are other greenhouse gases that contribute to this situation: water vapor, methane, ozone.Carbon dioxide is responsible for about half of global warming, while other gases are responsible for the other half.

ITT There are two major effects of global warming:

Increase of temperature on the earth by about 3° to 5 °C by the year 2100.

Rise of sea levels by at least 25 meters by the year 2100.

The increase of global temperatures is causing many effects on the climate.Sea levels are rising and patterns of precipitation are changing. when this happens, it increases the frequency.duration, and intensity of other extreme weather events such as floods, droughts,heat waves,and tornadoes.

Other effects of global warming are:deforestation, massive crop failures,extinction of species, and disappearance of coral reefs.
