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
East Pacific Rise Peru–Chile Trench along the coast of southern Chile. The southern extension of the East Pacific Rise (called the Pacific-Antarctic Ridge) merges with the Southeast Indian Ridge at the Macquarie Triple Junction south of New Zealand. Parts of the East Pacific Rise have oblique spreading, that is seafloor spreading that is not orthogonal to the nearest ridge segment. Along the East Pacific Rise the hydrothermal vents called black smokers were first discovered and have been extensively studied. These vents are forming volcanogenic massive sulfide ore deposits on the ocean floor. Many strange deep-water creatures have been found here. The southern stretch
