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) ultimate cause of the phenomenon, but states "there's no doubt that this anomaly in sea surface temperature is very meaningful". Sea surface temperature anomalies are a physical indicator which adversely affect the zooplankton (mainly copepods) in the Northeast Pacific and specifically in the Coastal Upwelling Domain. Warm waters are much less nutrient-rich than the cold upwelling waters which were the norm till recently off the Pacific Coast. This results in reduced phytoplankton productivity with knock on effects on the zooplankton which feed on it and the higher levels of the food chain.
