Climate Change

     Climate change is a significant time variation in weather patterns occurring over periods ranging from decades to millions of years. Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions. 
     Different factors affect the climate change. It is the varying influence of these factors that lead to different parts of the Earth experiencing differing climates. Some of these are distance from the sea, ocean currents, direction of prevailing winds, shape of the land, distance from the equator, and the El NiƱo Phenomenon.  Nowadays, human activity is also accepted as one of the factors that affect climate change.
     Different places also have different types of climate. We have 4 types of climate here in the Philippines. In Bulacan, the climate is Type II, in which there are two pronounced seasons, dry from November to April, and wet during the rest of the year. Maximum rain period is from June to September.
     Last month, July 2014, Typhoon Glenda (known as Typhoon Rammasun internationally), had destructive impacts across the Philippines, South China, and Vietnam. It resulted to damaged infrastructure and agricultural products. It also injured hundreds, affected more than one million, and left half a million homeless in all affected areas.
     Typhoon Glenda is a powerful tropical cyclone, like stated above, that has destructive impacts around some areas. While Typhoon Matmo (locally known as Henry), an International Convergence Zone (ITCZ) formed another tropical disturbance but due to typhoon Glenda being nearby, the disturbance started to weaken. The next day, it gathered warm waters and favorable conditions. On the other hand, Typhoon Inday has been first spotted by PAGASA east of Bicol as a tropical cyclone. But later on, it intesified into a storm.
