Historical
and projected sea surface anomalies
August
data for sea surface temperature anomalies on the Northern Hemisphere
contain a trendline pointing at a rise of 2°C (3.6°F) well before
the year 2030. In other words, if this trend continues, the Northern
Hemisphere sea surface will be 2°C (3.6°F) warmer in about a dozen
years time from now.
Such
a temperature rise would be catastrophic, as there are huge amounts
of methane contained in the form of hydrates and free gas in
sediments under the Arctic Ocean seafloor. A relatively small
temperature rise of part of these sediments could cause a huge abrupt
methane eruption, further speeding up local warming and triggering
further methane eruptions, in a spiral of runaway warming that will
cause mass destruction and extinction.

Record http://arctic-news.blogspot.com/…/august-2015-had-highest-s…
Across
the oceans, the August 2015 globally-averaged sea surface temperature
was 0.78°C (1.40°F) above the 20th century average—the highest
temperature for any month in the 1880–2015 record. NOAA analysis
further shows that in August 2015, the sea surface on the Northern
Hemisphere was 1.02°C (1.84°F) warmer than it was in the 20th
century.
