The Philippines and the Challenge of Climate Change (3rd Grading-No. 4)

During the 20th century, the average global temperature went up by about 0.74°C, with the warming affecting land more than ocean areas. In addition, average rate of warming over the last 50 years is nearly twice that for the last 100 years.

Further warming and changes in the global climate system during the 21st century could occur if greenhouse gas (GHG) emissions equal to or higher than current levels will persist. Among these are increased precipitation that could cause flooding in certain parts of the world while more intense and longer droughts are experienced in other areas, rising sea level, decreasing snow cover, melting glaciers and artic warming that also contribute to sea level rise. Climate change, if left unchecked, will also affect biodiversity and ultimately the earth's natural systems and processes.

The Philippines has experienced temperature spikes brought about by climate change. It has been observed that warming is experienced most in the northern and southern regions of the country, while Metro Manila has warmed less than most parts. In addition, the regions that have warmed the most (northern Luzon, Mindanao) have also dried the most. Largest precipitation trends are about 10 percent during the 20th century.

Hot days and hot nights have become more frequent. Extreme weather events have also occurred more frequently since 1980. These include deadly and damaging typhoons, floods, landslides, severe El Niño and La Niña events, drought, and forest fires. Adversely affected sectors include agriculture, fresh water, coastal and marine resources and health.

While the contribution of the Philippines to GHG emissions remains insignificant, there is no denying that the climate change issue affects all facets of the country's development. A business-as-usual option is no longer acceptable since the effects of climate change point to far-reaching consequences to the nation's food security, human health, water supply, settlements, and economic development. As part of the global community, the Philippines must do its part in helping mitigate carbon emissions.

QUESTION:

As a student, what actions can you do to help prevent climate change? (Bilang isang mag-aaral, ano ang magagawa o maitutulong mo para maiwasan ang tuluyang pagbabago (pag-init) ng ating klima at tuluyang pag-init o pagtaas ng temperatura ng mundo?)
