Oceans heating up rapidly, destroying marine life

Oceans heating up rapidly, destroying marine life

The global team analyzed a number of new studies assessing ocean temperatures to conclude that ocean warming is "stronger" than predicted by previous research.

"The ocean is the memory of climate change, along with melted ice, and 93% of the Earth's energy imbalance ends up in the ocean", said study co-author Kevin Trenberth, part of the Climate Analysis Section at the US National Center for Atmospheric Research.

The findings published on Thursday in the U.S. journal Science, led by the Chinese Academy of Sciences, debunk previous reports that suggested a so-called pause in global warming in recent years.

When the ocean becomes warmer, chances of global ice melting will be also increased drastically, and it may result in floods and other catastrophes in coastal areas. "There is no doubt, none!" the authors wrote in a statement.

Scientists say the warming seas are damaging coral reefs and marine life, and forcing fish to find deeper and colder waters.

'Ocean heating is a very important indicator of climate change, and we have robust evidence that it is warming more rapidly than we thought'.

In contrast, more than 1 million people were granted permanent residency in the U.S. during 2017. Getting a Chinese "green card" has been described as "one of the most hard tasks in the world".

The report claims that oceans are heating up as much as 40 percent faster than what the United Nations panel determined in 2014.

The new analysis, published in Science, shows that trends in ocean heat content match those predicted by leading climate change models, and that overall ocean warming is accelerating. An important factor for the more accurate Numbers a Maritime surveillance fleet with the name of Argo, which includes nearly 4000 floating robot.

That network has provided consistent data on ocean temperatures and other metrics since the mid-2000s.

Greenhouse gases warm the air and according to scientists, that heat gets absorbed by oceans. "The global warming signal is a lot easier to detect if it is changing in the oceans than on the surface".

"While 2018 will be the fourth warmest year on record on the surface, it will most certainly be the warmest year on record in the oceans, as was 2017 and 2016 before that", Hausfather said.

In the same direction, the European Union's Copernicus Climate Change Service estimated that 2018 had been the hottest year regarding global surface temperature. The studies accounted for the fact that older assessments of ocean temperature relied on less accurate methods than we have today. If no actions are taken ("business as usual"), the upper ocean above 2000 meters will warm by 2020 ZetaJoules by 2081-2100, which is about 6 times larger than the total ocean warming during the past 60 years. It has also contributed to increases in rainfall intensity and stronger, longer-lasting storms, such as Harvey in 2017 and Florence in 2018.
