It has been a while I have been writing something. It is so hot here and I feel like searching a bit on internet for the causes for this heat. I know it is the sun. But why can’t the sun’s heat be stopped from reaching earth? What was I taught in schools? Ozone layer protects the earth from ultra-violet rays and dangerous rays. Now, it appears like the rays doesn’t mind the ozone. Did ozone started strike? I don’t know. But I know one thing. The heat is increasing day by day. Searching internet made me to know some iinformation regarding global warming.
What is global warming?
According to wikipedia, ‘Global warming refers to an unequivocal and continuing rise in the average temperature of Earth’s climate system. Since 1971, 90% of the warming has occurred in the oceans. Despite the oceans’ dominant role in energy storage, the term “global warming” is also used to refer to increases in average temperature of the air and sea at Earth’s surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980. Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850.’
Oh, it would be too much problematic if ice began to melt at the poles. There are animals living in the ice. And when ice melts, naturally water level increases. Does islands disappear? Does some part of sea shore would be taken by sea? Doesn’t it seems horrible?
I was checking for the causes and it shows that the greenhouse gases are one of the main reasons. The major greenhouse gases are water vapor, which causes about 36–70% of the greenhouse effect; carbon dioxide (CO2), which causes 9–26%; methane (CH4), which causes 4–9%; and ozone (O3), which causes 3–7%. Clouds also affect the radiation balance through cloud forcings similar to greenhouse gases,
Human activity since the Industrial Revolution has increased the amount of greenhouse gases in the atmosphere, leading to increased radiative forcing from CO2, methane, tropospheric ozone, CFCs and nitrous oxide. According to work published in 2007, the concentrations of CO2 and methane have increased by 36% and 148% respectively since 1750.Less direct geological evidence indicates that CO2 values higher than this were last seen about 20 million years ago. Fossil fuel burning has produced about three-quarters of the increase in CO2 from human activity over the past 20 years. The rest of this increase is caused mostly by changes in land-use, particularly deforestation.
What can global warming do? It can affect the entire climate
What can be done against this? PUT YOUR HANDS AGAINST DEFORESTATION AND INDUSTRIALIZATION. OUR EARTH IS OUR MOTHER. IF LOST, IT CAN NEVER BE GAINED.
THIS MUST BE OUR MOTTO, LET THE TEMPERATURE DECREASE AND LET THE EARTH BE A PLACE WHERE EVERYONE CAN LIVE.
