Elevated sea temperatures drive impacts such as mass coral bleaching and mortality (very high confidence), with an analysis of the Coupled Model Intercomparison Project Phase 5 (CMIP5) ensemble projecting the loss of coral reefs from most sites globally by 2050 under mid to high rates of ocean warming (very likely).
There is concern that
elevated sea temperatures and ocean acidification may influence the resilience of coral reefs, inherently affecting their vital role of providing the structure which maintains ecosystem services around the world.
In response to
elevated sea temperatures, some corals may bleach, while other coral species in the same location may not.

The ongoing disappearance of
sea ice in the Arctic from
elevated temperatures is a factor to changes in atmospheric pressure that control jet streams of air, explained James Overland, an oceanographer of the National Oceanic and Atmospheric Administration, or NOAA.
«We report for the first time, a unique behavior where the deep -
sea skate, Bathyraja spinosissima, appears to be actively using the
elevated temperature of a hydrothermal vent environment to naturally «incubate» developing egg - cases,» the researchers wrote in the journal Scientific Reports on Feb. 8.
From August through October, NOAA satellites detected
elevated sea surface

However, to support the assertion that global warming is responsible for a great deal of damage from such events, it is sufficient to show that such events have the «signature» of global warming — for example, that specific global warming - related factors such as abnormally high
sea surface
temperatures,
elevated water vapor levels, and altered jet stream patterns contributed to making Hurricane Sandy what it was — even if those factors can not be precisely quantified.

Note we're using BEST land area, so actual rates of warming are slightly
elevated from global levels including
sea surface
temperatures, however BEST has enough resolution to allow us to work with 12.5 years of
temperature data and not have such abysmal CI as to need to reject the comparisons outright..
OTOH, the half that were well inland (but not greatly
elevated above
sea level) showed quite strong
temperature rises over the last 40 years.
With such
elevated sea surface
temperatures it is perhaps unsurprising that fossil evidence in ocean sediments indicates a mass extinction event during the PETM: the
seas would have become thermally stratified, cutting off the oxygen supply to deep waters and killing everything reliant upon it.
