According to an alarming report released Thursday, water temperatures are rising faster than scientists had previously concluded.
The study published in the journal Science indicated that scientists found various inaccuracies in the way sea temperatures were measured and warming. The values of the last decades were indeed higher than what the scientists had found in 2013 ,
"Current observation-based estimates show rapid warming of the Earth's oceans," states the report, which used four independent surveys to record the heat content of the oceans from 1
Oceans are warming mainly due to greenhouse gases released into the atmosphere by human activities. Emissions in the United States rose 3.4 percent last year from 2017 onwards – the second largest annual increase in more than two decades, according to a preliminary estimate by the economic research firm Rhodium Group.
The science report linked warming to more rain, elevated sea levels, coral reef destruction, decreasing oxygen levels in the ocean and declines in ice sheets, glaciers and ice caps in polar environments.
"The fairly steady rise of OHC [ocean heat content] shows that the planet is significantly warmed," said the report, adding that rising sea levels and temperatures should be affected, "given the numerous evidence of impacts on storms, hurricanes and the water cycle, including extreme precipitation events.
The report calculates two scenarios that show significant warming this century: The first scenario is in line with the Paris Climate Agreement's goal of reducing greenhouse gas emissions to prevent the global average temperature from rising by more than 2 ° C above pre-industrial levels. The second scenario assumes no change in emissions and warming of projects that could seriously affect marine and marine ecosystems.
A United Nations report warned October, the world has too little time to reduce greenhouse gas emissions before it could possibly see the catastrophic effects of climate change: diplomats from around the world reached an agreement in December to regulate the implementation of the Paris Pact and monitor emissions Countries to adopt.
The US has become The agreement was signed last month, despite President Donald Trump's commitment in 2017 to withdraw the country from the Paris Agreement. The US can not withdraw from the agreement by 2020.
