A global research into the health of the world's oceans has discovered that increasing global temperatures are distributing disease at an extraordinary level, threatening the worldwide food chains, which obviously include us. The discoveries propose that our oceans have 'absorbed' 93 % of the warming effects of climate conversion, causing them to become sicker and sicker in the course. This could describe why temperature ups and downs have not been felt as largely on land.
Inger Andersen, the Director General of the International Union for Conservation of Nature (IUCN), at the World Conservation Congress in Hawaii this month, said, "We all know that the oceans sustain this planet. We all know that the oceans provide every second breath we take. And yet, we are making the oceans sick."
The research, conducted by 80 scientists from 12 countries, is a huge analysis of hundreds of peer-reviewed researchers observing the reaction of marine eco-systems, from microscopic bacteria to huge sea mammals, to global warming. The research discovered that our oceans have been 'shielding' us from the shocking effects of warming since at least from the 1970s. Because oceans accommodate so much surface area on our planet, as radiation from the Sun strikes them, the heat is rapidly dissipated. In a world short of the oceans, much of that heat would have stayed, after bouncing off surfaces and getting stuck in the atmosphere, causing the planet to warm much sooner than ours is nowadays.
The report says, "By absorbing a disproportionate amount of heat from global warming, and by taking up the rapidly increasing emissions of carbon dioxide, the ocean has shielded the world from even more promp changes in climate. Yet, the extent to which it can continue to do so in the near and distant future is far from clear."
The team of researchers says that higher ocean temperatures are possibly causing marine life to migrate nearly 1.5 times faster than those on land, pushing creatures like seabirds, jellyfish, and plankton to migrate towards cooler seawaters by up to 10 degrees latitude. They also said that increasing heat has caused the oceans to become occupied with harmful microbes at a shocking level and that cholera bearing bacteria and deadly algal blooms are becoming more common. This means that water sources might quickly become toxic to ocean life and, obviously, the humans that eat them.
Co-lead author Dan Laffoley, from the IUCN, said, "We are no longer the casual observers in the room. What we have done is unwittingly put ourselves in the test tube where the experiment is being undertaken".
Besides making food supplies poisonous, the scientist says warming seawaters have caused coral ranges-regions where up to 25% of all marine life exists, to die off at record levels, which will also put a worry on the seafood industry. By 2050, harvests from aquatic fisheries in South-East Asia are likely to fall by between 10% and 30%, relative to 1970-2000, and most of the world's coral range systems will experience yearly bleaching difficulties. As of right now, only 38 % of the world's coral ranges live in seawaters with less enough acidity for them to grow well, down from 98% since the 1700s, when ocean acidification was first starting to increase. And it is not just tropical regions that are under danger.
The report says that if the ocean's temperature remains to rise like it is today, Arctic locations will take a major smash, as ice-covered regions are likely to disappear, leaving nothing but open water. In this situation, polar bears are expected to wipe out between 50 and 70 years from now. The scientists hope that their study will satisfy industries to change to greener technologies, because our oceans are at a verge of collapse, and they cannot bear the effect of global warming forever.
The study determines, "Finally, and most critical, is the need to address atmospheric CO2 and achieve rapid and significant reductions in what we emit. To do else will be to 'sleepwalk ourselves into a nightmare', where no level of conservation action in the future will be enough to overrule the impacts in order to save many of the ocean’s species, ecosystems, and benefits we currently rely on and take for granted."
The report was published at the IUCN’s World Conversation Congress in Hawaii this month.
