Unusually
high seawater temperatures may be a principal culprit
«The hurricane's strength was the result of
high seawater temperatures, and my first thought was that we should be able to do something about this», he says.
Synergistic impacts of
higher seawater temperatures and declining carbonate make these ecosystems even more vulnerable (e.g., Raven et al., 2005; Turley et al., 2006; Box 4.4).

higher temperatures.
With an average
temperature of eight degrees Fahrenheit, six times saltier water than
seawater, and the
highest nitrous oxide levels of any body of water on Earth, it's safe to call the Lake Vida research site a «challenging environment.»

seawater around the equator had a
temperature of 30 to 37 degrees Celsius, which is five to eight degrees

Radiation from a molecule at -80 C therefore can not provide enough energy in the form of photons, to warm molecules (by boosting electrons into
higher, more energetic orbits) at -4 C or above (
seawater temperatures).
