The
Great Unraveling
18
April, 2015
The
great unraveling of how climate catastrophe is unfolding on land and
in the oceans, in the atmosphere and the cryosphere, is becoming more
and more clear every month.
March 2015 temperatures were the highest for March in the 136-year period of record. NOAA analysis shows that the average temperature across global land and ocean surface temperatures combined for March 2015 was 0.85°C (1.53°F) higher than the 20th century average of 12.7°C (54.9°F).
Ocean temperature anomalies on the Northern Hemisphere for March 2015 were the highest on record. In many ways, the situation looks set to get worse. For the 12-month period from April to March, data from 1880 contain a trendline that points at a rise of 2 degrees Celsius by the year 2032, as illustrated by the image below.

The
rise in Northern Hemisphere ocean temperatures was especially
profound in September and October 2014, when methane started to erupt
from the Arctic Ocean seafloor in huge quantities.
The image below shows a polynomial trendline pointing at an October Northern Hemisphere sea surface temperature anomaly rise of 2°C (3.6°F) by 2030, and a rise of more than 5°C (9°F) by 2050, compared to the 20th century average, from an earlier post.

The images below give an idea of the current sea surface temperature anomalies around North America.
On April 11, 2015, a sea surface temperature of 22.2°C (71.96°F) was recorded off the North
American coast (green circle bottom), a 12.6°C (22.68°F) anomaly (green circle top).
A continued rise of ocean temperatures on the Northern Hemisphere threatens to unleash huge eruptions of methane from the seafloor of the Arctic Ocean, further accelerating the temperature rise in the Arctic.
Temperature
anomalies as high as 10.2°C (or 18.3°F) were recorded for March
2015 on Kolguyev Island in the Barents Sea.
A rise in ocean temperatures on the Northern Hemisphere of 2°C (3.6°F) by October 2030 looks set to go hand in hand with a 7°C (12.6°F) rise in Arctic temperatures by 2030, fueling runaway global warming.

In
conclusion, the situation is dire and calls for comprehensive and
effective action, as discussed at the Climate
Plan blog.
