One study found that the rising sea level can be accelerated by weak ice shelves in the Antarctic.
Researchers at Waterloo University in Canada found that the process of hot seawater reduction of snow shelves from below is also separating them from above, which would break them.
Christine Dow said from the University of Waterloo, “We are learning that the ice shelves are more vulnerable than the rising ocean and air temperature.”
Dow said, “There are double processes going on here, which is becoming unstable from the bottom, and the other is from above. This information can affect our estimated timetable for the fall of the ice shelter, and climate change Due sea level has increased. “
A study published in Journal Science Advanced applied the same methods of forensic science on ice shelves which had already been lost.
Through Radar Surveys, it gives that the straight forward proof that a calming program in Nansen Ice Shelf in Ross Sagar was the result of fractures operated by molten channels under the ice shelf. Since hot salt water erases channels in the snow which connects the glaciers to the stable land, it also generates large vertical fractures dividing the glaciers from the top and bottom.
Thawing surface water at the top of snow shelves, then pouring into these cracks, furthering the problem.
Dow said, “This study is more evidence that the warming effects of climate change are affecting our planet in ways that are probably more dangerous than what we thought.”
“Antarctic has many more weak ice shelves that, if they break, then the process of sea level rise will increase.”
One study found that the sensitive areas of the world will remain at risk of dangerous and potentially irreversible effects of climate change, even if we meet the goal of not increasing the global temperature above 1.5 ° C in the next 100 years.
Research done under the leadership of Open University and Sheffield University in the UK reviewed the 2015 targets set out in the Paris Climate Agreement and concluded that areas which are Arctica and Southeast Asian Monsoon Areas can be irreversibly harmed. Are especially sensitive for global temperature changes
Some Paris climate agreement are not explored firstly because it is so far, researchers have used either a very easy model that was very complex to check the extent of the possibilities, Philip Holden said Open University.
The study published in Nature Climate Change magazine found that to increase the target of global average temperatures by 2015, the Paris Climate Agreement is not dependent on future generations to reduce the growth of two degrees Celsius, thereby allowing huge amounts of carbon can be removed Earth’s Atmosphere
Instead, the government can achieve goals through reduction in emissions, but only when they work to promote a series of policies to fully support the current pace of technological change. Professor Richard Wilkin said, “By accounting for climate-carbon cycle uncertainties, we have been able to show that the estimated 50 percent chance that we can limit the peak-industrial-peak crop to global warming below 1.6 degree Celsius. “
