"Safe Our Planet"


Do you all notice that weather nowadays is getting hotter compared to the past? For your information, we call these phenomena as the global warming effect. I'm sure that many people heard this before but do they really understand what is the real effect of global warming to human kind and our beloved planet? Today, me and my partners will explain a little bit about global warming to everyone of you and hoping by doing so, we can create awareness among everyone to safe our planet from being destroyed before is too late. Actually, the meaning of global warming effect refers to the documented chronological warming of the Earth's surface based upon international temperature records that have been continued by humans since the early aged. The surface of the earth has always been warmed from solar radiation and the "greenhouse effect." This has caused ice from Atlantic has been melting seriously. The atmosphere is like a greenhouse in that it traps the heat, but is does so in a different way. "Greenhouse gases" absorb some of the radiant energy from the sun and some of the warmth from the Earth and re-radiates some of it out into space and some back to the Earth. Studies had showed that the sea level continued to increase continuously for the 20th century of about 1.7 mm per year. Measurements show that the 2007 global averaged sea level is about 20 cm higher than the 1870 estimate. Modern satellite measurements show that since 1993 global averaged sea level has been rising at about 3 mm per year and if this continues to happen, it will definitely endanger our life and bring a lot of trouble to our life.
