FULL STORY ========================================================================== Global warming is driving an unprecedented rise in sea temperatures
including in the Mediterranean, according to a major new report published
by the peer- reviewed Journal of Operational Oceanography.

Data from the European Union's (EU) Copernicus Marine Environment
Monitoring Service (CMEMS) will increase concerns about the threat to
the world's seas and oceans from climate change.

The Ocean State Report reveals an overall trend globally of surface
warming based on evidence from 1993 to 2018, with the largest rise in
the Arctic Ocean.

European seas experienced record high temperatures in 2018, a phenomenon
which the researchers attribute to extreme weather conditions -- a marine
heat wave lasting several months.

In the same year, a large mass of warm water occurred in the northeast
Pacific Ocean, according to the report. This was similar to a marine
heatwave -- dubbed 'the Blob' -- which was first detected in 2013 and
had devastating effects on marine life.

Now the study authors are calling for improved monitoring to provide
better data and knowledge. They argue this will help countries progress
towards sustainable use of seas and oceans which are an essential source
of food, energy and other resources.

Findings from the report confirm record rises in sea temperatures
"Changes to the ocean have impacted on these (ocean) ecosystem services
and stretched them to unsustainable limits," says Karina von Schuckmann
and Pierre- Yves Le Traon, the report's editors.

"More than ever a long term, comprehensive and systematic monitoring, assessment and reporting of the ocean is required. This is to ensure a sustainable science-based management of the ocean for societal benefit."
The Ocean State Report identifies other major strains on the world's seas
and oceans from climate change including acidification caused by carbon
dioxide uptake from the atmosphere, sea level rise, loss of oxygen and
sea ice retreat.

Long-term evidence of global warming outlined in the report includes
a decrease over 30 years of up to two days in the period of Baltic Sea
ice cover and an acceleration in the global mean sea level rise.

The report highlights that the message from recent EU and global
assessments of the state of seas and oceans is 'we are not doing
well'. The authors add: "Human society has always been dependent on the
seas. Failure to reach good environmental status for our seas and oceans
is not an option."
