A new hidden difficulty to control climate change scientists have discovered, as well the oceans of our planet absorb more the heat that they thought up to now.
In particular, a new scientific study revealed that during the period 1991-2016, the seas had conserved approximately 60% more heat, compared to previous badessments made by the United Nations Intergovernmental Panel on Climate Change (IPCC) since 2014.
In fact, according to scientists, this means that the Earth is more exposed to fossil fuel emissions than we thought until now. & # 39; & # 39;
So, humanity maybe even a shorter window of time to avoid a devastating climate change.
After a new badessment of the absorption of the seas (based on a new more accurate measurement method), scientists believe that – so that the overall temperature rise does not exceed two degrees Celsius relative to the levels preindustrial – carbon dioxide emissions, the main "greenhouse gas", must be reduced by 25% more compared to previous estimates.
Researchers from Princeton University and the Scripps Institute of Oceanography of the University of California, led by Assistant Professor of Earth Sciences, Los Rospandi, who published the publication in the journal Nature, have estimated that during the period 1991-2016 the Earth's oceans absorbed more than 13 zettajoules of thermal energy (one joule followed by 21 zeros). This energy is 150 times higher than that produced by people every year in the form of electricity.
Scientists know that the oceans absorb about 90% of all the extra heat produced by global warming. The discovery that the seas absorb even more heat, apart from the impact on climate change, means that even less oxygen will be available in the available water for marine organisms and ecosystems, while sea level will also rise. when the water is heated, it "swells".
