Pacific Ocean width at about 5°N latitude, where it stretches approximately from Indonesia to the coast of Colombia—halfway around the world, and more than five times the diameter of the Moon. The lowest known point on Earth—the Mariana Trench—lies below sea level. Its average depth is , putting the total water volume at roughly . Due to the effects of plate tectonics, the Pacific Ocean is currently shrinking by roughly per year on three sides, roughly averaging a year. By contrast, the Atlantic Ocean is increasing in size. Along the Pacific Ocean's irregular western margins lie many seas, the largest of which
Environmental issues in the Philippines saw its average temperature rise by 0.65 degrees Celsius, with fewer recorded cold nights and more hot days. Since the 1970s, the number of typhoons during the "El Niño" season has increased. The Philippines has not only seen 0.15 meters of sea level rise since 1940, but also seen 0.6 to 1 degree Celsius increase in sea surface temperatures since 1910, and 0.09 degree c increase in ocean temperatures since 1950. During the time period from 1990 to 2006, the Philippines experienced a number of record-breaking weather events, including the strongest typhoon (wind speeds), the most destructive typhoons (damages), the
