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
Pacific Marine Ecozone (CEC) coast, so there is little oceanic water exchanged between the Arctic and Pacific ecozones. The moderating effect of the Pacific Ocean results in a nearly constant year-round temperature in this ecozone. The Alaska Peninsula also inhibits the flow of cold Arctic currents from entering this zone, ensuring that throughout its extent, there is little variation in temperature. In fact, there is little exchange of oceanic waters between the Pacific Ocean and the Arctic Ocean. Ice forms here infrequently, and only in its northern areas in the Bering Sea and the Sea of Okhotsk. Pacific Marine Ecozone (CEC) The Pacific Marine
