Pandolfi and colleagues review the threats posed to coral reefs by increased ocean heat content and acidification and point to the role of evolution in buffering populations. (sciencemag.org)
For heat, as with CO2 (where the ocean is the largest reservoir), increasing ocean heat content may have a price in the future (see ocean acidification with respect to CO2). (dotearth.blogs.nytimes.com)
A wide range of other observations (such as reduced Arctic sea ice extent and increased ocean heat content) and indications from the natural world (such as poleward shifts of temperature - sensitive species of fish, mammals, insects, etc.) together provide incontrovertible evidence of planetary - scale warming.
