Climate Change: The Local Scenario

I learned that one of the major tribulations of the world today is Climate Change. Humanity has a lot to do with the recent warming of the Earth's atmosphere. It is because of man's numerous activities that release greenhouse gases in our atmosphere. And this results to the rise in temperature of the whole world. The different types of greenhouse gases are as follow:
Carbon Dioxide - comes from the emissions of diesel and gasoline by motor vehicles and from various industries.
Methane - comes from agriculture and decaying trash
Nitrous oxide - comes from biomass burning, intensive agriculture, motor vehicles, and industries
Hydrofluorocarbons, hyperfluorocarbons, sulfur hexafluoride - comes from aerosols and industrial coolants.
Greenhouse gases are sent into the air when we use excessive energy in watching TV, using air conditioner, hair dryer, microwave oven and other appliances. The electricity we use for these comes from power plants. Most power plants burn coal and oil which produce greenhouse gases.
Climate change has many effects on different aspects.
Health – increase in respiratory diseases, infectious diseases and weather-related mortality
Agriculture – changes in crop yields, irrigation demand and productivity
Forests - changes in ecology, geographic range of species, its health and productivity
Water Resources – decrease in water supply and quality, competition issues in water
Industry and energy - demand and supply in energy
Since Philippines is an archipelago, several areas in our country are highly vulnerable to the impacts of climate change. Flooding, sea level rise, and salt water intrusion are the direct effects of climate change. Our country has various natural resources which contribute to the livelihood and food of approximately 64.7 million population in coastal areas
The increasing development and industrialization results to the growth of population of these communities and the change in climate poses an enormous effect on the livelihood of these people.
One of our problems here in the Philippines is storm. With global warming, sea temperature raises causing storms to be formed. If you look at the map of the Pacific ocean, most storms are focused towards the Philippines before going to other countries. Several extreme events were the occurrence of the super typhoons in 2006 namely Typhoon Paeng, Reming, Semiang, Milenyo.
Climate change has several impacts on our physical and biological systems. Because of this, there will be an increase in frequency and intensity of El Niño Southern Oscillation phenomenon. Due to sea level rise, the beaches and shorelines may erode. Floods may also result to the inundation of several coastal areas especially in the eastern Philippines. The seas will increase its salinity causing a lesser mangrove production. It will also be harmful for sea grasses and such. Due to this, there will be less nutrients available for marine life.
Coral bleaching is when corals die out because of the warmer sea temperature, affecting the food chain since it is the main source of food.
Many adaptations have to be made to all the coastal communities with large exposure to climate change in order to moderate its damages. Simple ways can actually be a great help like avoiding the release of greenhouse gases. Proper care of water resources, trees, plants etc. There should be significant attention to the environment.
I watched a video presentation about “Climate Change: The Local Scenario.”
I participated in the online discussion by expressing thoughts and ideas about our Earth in my blog and by sharing what I learned on the video presentation that I watched.
