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
Threats to sea turtles especially of the Hawksbill variety which are desired for the striking details of the shell. Global warming is estimated to have serious effects on wildlife over the next few decades. There is evidence that sea turtles have already been affected. With the increase of temperature, polar ice has melted and has led to the rise of sea levels. This rise in sea levels has been a factor in the loss of beach, which for sea turtles means less nesting area. Global warming has been associated with severe weather, which could mean harsh and numerous storms that erode beaches and flood
