Sea surface temperature monitor and predict the El Niño phenomenon. Weather satellites have been available to determine sea surface temperature information since 1967, with the first global composites created during 1970. Since 1982, satellites have been increasingly utilized to measure SST and have allowed its spatial and temporal variation to be viewed more fully. Satellite measurements of SST are in reasonable agreement with in situ temperature measurements. The satellite measurement is made by sensing the ocean radiation in two or more wavelengths within the infrared part of the electromagnetic spectrum or other parts of the spectrum which can then be empirically related to
Sea level rise (8%). The sea level will not rise uniformly everywhere on Earth, and it will even drop in some locations. Local factors include tectonic effects and subsidence of the land, tides, currents and storms. The rising trend is expected to continue for centuries. Because of long response times of the climate system, it has been estimated that each Celsius degree of temperature rise would trigger a sea level rise of approximately over the next 2,000 years. Sea level rises can considerably influence human populations in coastal and island regions and natural environments like marine ecosystems. Widespread coastal flooding would be expected
