The oceans absorb 90 percent of the heat from greenhouse gases. 2019 they were record warm. The last ten years have been the hottest ten years ever measured. It is clear evidence of the accelerating global warming of our planet.
The greenhouse gases emitted from, for example, fossil fuels, logging and the meat industry are heating up our planet and things are moving faster. Over the past ten years, the sea temperature record has replaced each other, but the 2019 heat increase was higher than in ten years, according to an analysis in Advances In Atmospheric Sciences. In addition, warming between 1987 and 2019 was 4.5 times faster than between 1955 and 1986.
The increase in temperature leads to stronger storms, altered waterways, increased sea level, more floods, droughts and fires.
– The data we have is undeniable, but there is still hope because people can still take action. We just haven’t taken any meaningful action yet, John Abraham, a professor at the University of St. Thomas, Minnesota, told The Guardian.
At the end of 2019, a report came out that several important systems linked to the seas are about to be disrupted. For example, at two degrees of warming, 99 percent of the world’s coral reefs are estimated to have died out. It will have major consequences for life in the seas and, in turn, for millions of people’s opportunity to support themselves.
The melting ice risks passing a point where they cannot recover and which within a few hundred years can give many meters high sea levels. According to new research, Greenland’s ice cover may be doomed to melt away already at 1.5 degrees of heating, which is expected to take place in 2030. In the long term, this may give rise to a seven-meter sea level rise.
