Effects of Global warming

The biggest effect of Global warming is the increase in the planet’s temperature. The increase in temperature is linked to the climate change that the planet is currently experiencing. So what are the effects? Since the temperature is rising rapidly, the planet’s ice is melting is rapid speed. So why is it that important? The large mass of ice is responsible to deflecting the sun’s rays. The greenhouse gases are responsible for trapping the heat for the sun. But too much heat trapped in the planet is not good either. Another downside if the planet’s ice melts is the increase in the planet’s sea level. A large percentage of the world’s population resides in low lying areas. If sea level increases, millions of people would be relocated. When that happen a large number of people would have problem finding shelter, food to eat and clean water to drink.

Since the large mass of ice is melting, and the amount of the sun rays deflected is decreasing, the planet’s waters absorbs the heat. How bad could that be? Studies have shown that a storm’s intensity increases when it passes warm water. That is the case with Hurricane Katrina which hit the United States and destroyed properties and claimed the lives of a lot of people in New Orleans. 

Another effect of the warming body of water is the bleaching. A lot of animal species in the ocean and sea rely on coral reef for their source of food. Bleaching is destroying the Coral reefs leaving a lot of marine species vulnerable to extinction. Global warming does not only affect marine animals. Certain animal species rely on the temperature of their habitat to survive. Penguins and Polar Bears are among the animals that rely on cold climate to survive. Since the ice is melting, certain species travel far distance to find an suitable place to live and most of the animals do not survive traveling the long distance.

Another effect of Global warming is the decrease and increase of the amount of precipitation. Last year, the Philippines was hit by two powerful storms Peping and Ondoy. The amount of rainfall during typhoon Ondoy was a month’s worth of rain. The number of occurrence of floods and landslide while also increase. The other side of change of the amount of precipitation is drought. During the early months of the year, the country has experience the El Nino Phenomenon. Droughts has ravage crop and almost put the country at risk of a water crisis. The drought intensified when the summer season in Philippines started. The heat in Metro Manila has reached as high as 38 degrees Celsius this summer.

The Philippines is at high risk to effects of global warming. Even though there are no large masses of ice near the archipelago, parts of the country is still at risk of being submerged if the sea level increases. There are lots of densely populated areas in the Philippines which are located on low lying areas. The drought this year was particularly a big burden to the country. Crops were destroyed which caused the prices of basic needs to increase. The country almost faced a water crisis as efforts to find a solution to the declining water supply such as cloud seeding proved ineffective.

El Nino Phenomenon continues to plague the Philippines.

If you’re in the Philippines, you won’t need a thermometer to know that the Philippines is having one of the hottest summer in history.  During earlier months of the year, the cold evening breeze is a relief from scorching heat. This is due from the winter ice melting from countries on the northern hemisphere. But now all the ice has melted and the summer season has begun, escaping the heat is a challenge.

I usually take a shower at night before sleeping to refresh myself. Due to this heat, it only takes a few minutes before I get all sweaty again. I have always thought that having an air conditioner is a luxury since electricity in the Philippines is costly. But now I am starting to think that it is a necessity. If this heat keeps up, I would consider buying one regardless of the cost of the electric bills.

You have to add the El Nino phenomenon to equation. The Country has been experiencing drought as early as  February. I hope the drought does not become a yearly event. If it does this will be a problem to the agriculture of the Philippines. Personally, I having problem staying outdoors nowadays. The daily commute   to the office is such a burden. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has expects that the drought would last until May. The hottest temperature in Metro Manila was at 36.8 degrees Celsius so far. PAGASA expects the temperature would rise higher in the coming weeks

Temperature rises in the Philippines

The temperature has been high in the last few months that on most days I take refuge in air condition malls located near my residence. I have never considered purchasing an air conditioner but I am starting to think that it is becoming more of a necessity rather than a luxury. Yesterday the temperature in Metro Manila has reached 36.1 degrees Celsius. A month ago on March 6, temperature has risen to 35.8 degrees. The highest temperature in Metro Manila was recorded on May 14, 1987 and was at 38.5 degrees Celsius.

The Philippine Atmospheric,  Geophysical, and Astronomical Services Administration (PAGASA) has forecasted the temperature would reached 35 to 36 degrees Celsius until the weekend and reach as high as 37 degrees all over the country within this month or on May.

If the temperature is high in Metro Manila, it is nothing compared to Tuguegarao where temperature is expected to reach as high as 37 to 38 degrees Celsius in the next four days. The highest temperature recorded in the Philippine is at 42.2 degrees Celsius in Tuguegarao on May 11, 1969

Just before coming to work, I travelled from Pampanga to my office in Quezon City. I expected that it would be a lot cooler in the province compared to Quezon City but I was wrong. It was hotter there despite that there are more trees. I think the problem is that there is only a warm breeze there.  I hope that the temperature would go down as soon as the drought ends. It has really been difficult to commute lately. I wonder how it would be if the Global temperature rises and when the day comes that a 36 degree temperature is a natural occurrence in the Philippines.  An increase of a few degrees would post a lot of problem to a lot of Filipinos. How I wish this drought ends soon.

Droughts threatens Philippines’ water supply.


It hasn’t rain much since September last year. The country is under a dry spell which is predicted to last until July. According to the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa), Benguet, Batanes, Isabela, Cagayan, Bulacan, Nueva Ecija, Nieva Viscaya, Pampanga, Batangas, Iloilo, Antique, Negros Occidental and Guimaras are experiencing drought.

The water level in Magat Dam in Isabela continuous to dropped and is 166.51 meters (21 meters below normal) as of Feb 10, 2010. Ideally, Magat dam water level should be at 192 meters. The dam provides the water needs of major irrigation for 80,000 hectares of farmlands in Quirino, Cagayan and Isabela. It also provides the waters needs of the hydroelectric plant in Ramon, Isabela which is responsible for 350 megawatts of power to the Luzon grid. To provide the daily water requirements for the hydroelectric plant and irrigations, water levels in Magat dam should be at least 187 to 188 meters

The water level of three other dams in Luzon are also decreasing but has not reached critical levels. The following dams are Angat dam in Bulacan. San Roque dam in Pangasinan and Pantabangan dam in Nueva Ecija. Angat dam water level is now at 198.61 meters (2.39 meters below ideal level). Pantabangan dam is 2.91 meters below normal while san Roque has a 1.38 meter deficit of the normal level.

The government is looking into cloud seeding and rationing of the water supply in several areas in the Philippines. Maynilad Plans to fix their facilities to prevent unnecessary loss of water.
The drought is brought by the El Niño Phenomenon. If it would last as long as they predicted, the Philippines would face a water shortage. The drought that the Philippines is facing is one of the effects of Global warming. If people were not taking it serious then, they should take it serious now. Everyone in the Planet is affected. It is easier to ignore the issue if the person has not been affected by the effects of Global warming.

Last year, I experienced firsthand how devastating it could be when nature goes wild. It is hard to believe that a few months ago the rainfall during Typhoon Ondoy (international codename) has reached a record high in the Philippines. The Philippines was caught unprepared for the havoc Ondoy has brought. Everyone never thought that it would be possible to rain as hard nor it would flood so extensively.
