Global Warming
The earth’s atmosphere is compound with many gases, mostly nitrogen and oxygen, the other gases are known as “greenhouse gases”, we can not see them or smell them but they are there,the most known greenhouse gases are carbon dioxide, methane and nitrogen dioxide. These gases are needed to maintain an appropriate earth temperature, necessary to create a habitable environment; thething is that human activity has produced much more of the gases that we need, and the increase of these gases has produce global warming.
Global warming is a climatic change; this change ismanifested by the increase in the average temperature of Earth's near-surface air and oceans and it has been happening since 1850, it has been caused by high concentrations of greenhouse gases, this gases area result from human activities such as the burning of fossil fuel and deforestation among others.
I’ve chosen this topic because it’s something that affects everybody no matter age, skin color,gender or socioeconomic status; we all suffer the consequences of this problem, but more importantly we all have the solution to this problem in our hands.
According to IPCC (Inter-governmental Panel onClimate Change) its 2007 report indicated that the global surface temperature is likely to rise a further 1.1 to 6.4 °C during the 21st century. According to scientist an increase in globaltemperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. Warming is expected to be strongest in the Arctic andwould be associated with continuing retreat of glaciers and sea ice. Other effects of the global warming include more frequent occurrence of extreme weather events including heatwaves, droughts and heavyrainfall events, species extinctions due to shifting temperature regimes, and changes in agricultural yields.
