About 93 percent of excess heat trapped around the Earth by greenhouse gases that come from the burning of fossil fuels accumulates in the world’s oceans.
The UN Intergovernmental Panel on Climate Change (IPCC) says ocean warming has led to rising sea levels and contributes to increases in rainfall intensity, more violent storms and the destruction of coral reefs.
Threat - Biodiversity - Earth - Food - Supplies
It is also a threat to biodiversity and one of the earth’s major food supplies.
“Ocean heating is a very important indicator of climate change, and we have robust evidence that it is warming more rapidly than we thought,” said co-author Zeke Hausfather, a graduate student in the Energy and Resources Group at the University of California, Berkeley.
Report - Studies - Conclusions - Measurements - Fleet
Their report relied on four studies, published between 2014 and 2017 whose conclusions are based on measurements recorded by a fleet of some 4,000 floating robot monitors called Argo.
The robots drift throughout the world’s oceans, every few days diving to a depth of 2,000 meters and measuring the ocean’s temperature, pH, salinity and other information.
Argo - Data - Heat - Content - Mid-2000s
Argo “has provided consistent and widespread data on ocean heat content since the mid-2000s,” the report said.
The new analysis shows warming in the oceans is on pace with measurements of rising air temperature.
Nothing - Greenhouse - Gases - Models - Temperature
And if nothing is done to reduce greenhouse gases, “models predict that the temperature of the top 2,000 meters of the world’s...
