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
The Blob (Pacific Ocean) second off Alaska and in the Bering Sea; and the third and smallest, off Southern California and Mexico. In February 2014, the temperature of the Blob was around warmer than what was usual for the time of year. A NOAA scientist noted in September 2014, based on ocean temperature records, that the North Pacific Ocean had not previously experienced temperatures so warm since climatologists began taking recordings. The immediate cause of the phenomenon is the lower than normal rates of heat loss from the sea to the atmosphere, compounded with lower than usual water circulation resulting in a static upper
