Climate change in deep oceans could be seven times faster by middle of century, report says
Uneven heating could have major impact on marine wildlife, as species that rely on each other for survival are forced to move
Rates of climate change in the world’s ocean depths could be seven times higher than current levels by the second half of this century even if emissions of greenhouse gases were cut dramatically, according to new research.
Different global heating at different depths could have major impacts on ocean wildlife, causing disconnects as species that rely on each other for survival are forced to move.
In the new research, scientists looked at a measure called climate velocity – the speed at which species would need to move to stay within their preferred temperature range as different ocean layers warm.
The study, published in the journal Nature Climate Change, found different parts of the ocean would change at different rates as the extra heat from increasing levels of greenhouse gases moved through the vast ocean depths
By the second half of the century, the study found “a rapid acceleration of climate change exposure throughout the water column”
The study used climate models to first estimate the current rates of climate velocity at different ocean depths, and then future rates under three scenarios – one where emissions started to fall from now; another where they began to fall by the middle of this century; and a third where emissions continued to rise up to 2100.http://www.blueskye.lifehttp://www.blueskye.livehttp://www.blueskye.newshttp://www.blueskyefoundation.com#globalwarming #climatechange #carboncompensation #bluesky #climateemergency #climatecrisis #blueskye #blueskyefoundation #compensate #greentechexchange #zerocarbon #climatenews #wastemanagement #blueskyelife #climatestrike #theclimatestrike #blueskyenews #globalheating #biodiversity #climateprotest #climateactivist #extinction #parisagreement #blueskyfoundation #ilmastonmuutos
