Global Warming and Climate Change

Global warming and climate change are the most pressing threats that mankind is facing today. It is a serious threats to both national and international survival. Hence, times call for total mobilization of all sectors in order to mitigate the tipping point warned by scientists. We can all help fight climate change through simple way by doing day-to-day activities such as the following; 1. Manage Garbage. Practice proper waste management through segregation and composting so that garbage will not be left to rot because when garbage decomposes, it produces methane, a lethal greenhouse gas that is 20 times more point than carbon dioxide. Use cloth bags and don't burn plastics. 2. Grow Trees. Trees need carbon dioxide to survive so the more trees we plant and grow the more carbon dioxide is absorbed. It also protect us from floods because the roots are like sponges that draw in rainwater. 3. Conserve Energy. In our homes, schools,offices,shops,stores, malls and processing plants by


turning off light bulbs, electric fans and air conditioning that are not being used. Electricity generated from power plants that mainly use polluting fossil fuels such as coal and bunker oil. So less energy use will mean less carbon dioxide emissions. So before you throw that plastic wrapper on the street, before you dream of a new car, before you turn on the air-conditioning,before you ride in a motor vehicle,jeep or bus, pause for a while and think about climate change because the little things you do in just about anywhere, everyday, all contribute to global warming.
The entire world is now facing the dangers of Global warming and Climate Change, characterized by the abrupt changing of the Eart's temperature, mainly caused by 200 years of fossil-fuel based industrialization, urbanization and agriculture.
MAJOR CAUSES: the main contributors to climate change are greenhouse gases (GHG) which accumulate in the atmosphere and stays there for at least 200 years, trapping heat that we releases. The major GHGs are: Carbon Dioxide or CO2 from the burning of fossil fuels from our vehicles and industries. CO2 remains in the atmosphere for 200 years. Methane is produced by the rotting of garbage in dumpsite. It is 20 times more lethal than carbon dioxide.
TIPPING POINT: As global warming continues, scientists point out that the world is moving towards a dangerous tipping point of irreversible climate change in the year 2050. The current level of greenhouse gases trapped in the atmosphere is 372 parts per million (ppm). Scientists report that if the 450ppm level is reached, the world would reach that tipping point. At 450 parts per million, a 2-degree centigrade increase in global temperature will happen. Ice caps as thick as three miles, like those of Greenland, well melt, raising sea levels by 6 to 7 meters.
EFFECTS OF CLIMATE CHANGE: A 7-meter rise of sea levels will drastically reduce the land areas and will be permanently under water. In the Philippines, half of the countries 1,610 municipalities and cities are located along coastlines with 80% percent of the population dependent on seafood as a primary source of protein. A mere one-meter increase in sea level would destroy or drastically affect living conditions in 64 of the country's 81 provinces.
