Coral reefs are at risk warns the acidification of the oceans

Climate Change is devastating our oceans and frozen regions like never before, a major new Report by the United Nations .

the water will Rise , the ice melts, and to move the species habitat by human activities.

And the loss of the permanently frozen lands threatens to unleash yet more carbon, accelerating The Decline .

There is some guarded hope that the worst effects can be avoided with Deep and immediate reductions of carbon emissions.

This is the third in a series of special reports produced by the Intergovernmental Panel on Climate Change (IPCC) in the last 12 months.

The Scientists looked at previously, to cope with The World . She also told the

But this new study is the impact of rising temperatures on our oceans and frozen regions, perhaps of The Most disturbing and depressing of the three.

So, what have you found and how bad is it? In a nutshell, The Waters are warmer, The World is melting the ice fast, and this will have consequences for almost every living thing on The Planet .

"The Blue Planet is in Serious Danger now is suffering a lot of insults from various directions and it is our fault," said Dr. Jean-Pierre Gattuso, a coordinating lead author of The Report .

low-lying Small Island States will be hit hard by the Rise in sea levels, scientists are "virtually certain" that the global ocean has warmed up now, without a break, since 1970.

soaked in water were More Than 90% of the additional heat by People in the course of The Past decades and the rate at which it has taken, This Heat has doubled since 1993.

The seas were to Rise primarily due to thermal expansion - this refers to the way the volume of water expands when it is heated. The additional energy makes the water molecules move more, causing them to take up more space. But the IPCC says that rising water levels are now driven mainly by the melting of Greenland and the Antarctic.

Interactive Qaleraliq glacier in southern Greenland 2018, in 1993, thanks to the warming, the loss of mass of (refers to the amount of ice that melts and is lost, since there is no liquid water) from the Antarctic Ice Sheet in The Years between 2007 and 2016, tripled in comparison to the 10 years previously.

Greenland, saw a doubling of the mass loss in the same period of time. The Report expects this to continue throughout the 21St Century and beyond.

For the glacier in areas such as the tropical Andes and in Central-Europe and North-Asia, the projections are that you will lose 80% of its ice by the year 2100 under a high carbon emissions scenario. This is a huge impact on millions of People .

glaciers around The World are losing their ice cream quickly What are the implications of all this melting ice? All of the bubbles out extra water down to the oceans the average ocean water drives level around The World . This will continue to come over the decades.

This new Report says that global mean Sea Level could increase by up to 1. 1m by 2100, in the worst warming scenario. This is an increase of 10cm in previous IPCC projections is due to the larger ice loss in the Antarctic.

"What surprised me The Most is the fact that the highest projected sea-level Rise have been revised upwards and it is now 1 is. 1 m," said Dr. Jean-Pierre Gattuso, from CNRS, France's national Science Agency.

"This will have far-reaching consequences for the low-lying coasts, where almost 700 million People live, and it is a cause for concern. "

analysis by David Shukman Science Editor, HullAn The East coast of England, most of The City of Hull is located below The Level of a typical Flood . The Sea here can be both a source of wealth and a threat to life.

So that the conclusions of the IPCC Report have real meaning. A storm tide on a winter Six Years ago, the weak link was night in a Sea Wall and flooded shops and houses.

New defenses were ordered, and the construction teams are now at work along The Shore . But the obstacles do not protect everyone. Computer simulations, developed by the University of Hull, show that, if The Level of The Sea is a metre higher than the centre of The City should be fine, but the neighboring areas to go.

This shows a painful question to face, to be stored in low-lying places in The World : what is and what should be abandoned, since the water Rise ?

Sea Level Rise was previously taken care of mainly by the thermal expansion of the oceans, but the melting of Greenland and the Antarctic has now, as The Principle driver says The Report makes it clear that some island States are likely to be uninhabitable will be about 2100.

The Scientists also say that the relocation of People away from threatened communities is worth considering "if safe alternative locations are available".

do these changes mean For You ? One of The Most important news is the way that the warming of the oceans and the cryosphere (the icy bits on the land) is part of a chain of bad results that will affect millions of People in The Future .

Under the higher emissions scenarios, also wealthy mega-cities such as New York or Shanghai, and large tropical agricultural deltas such as the Mekong river face a high or very high risks that Rise from The Sea .

The Report says that a world with highly elevated values of warm water, in turn, give Rise to large increases in unpleasant and dangerous weather events, such as surges of tropical cyclones.

"Extreme Sea Level events are historically rare (once per century in the recent past) are likely to occur more frequently (at least once per year) in many locations, by 2050," the study says, even if future emissions of carbon dioxide are significantly lower.

"What we see now is, that permanent and unprecedented change," said Prof Debra Roberts, co-chair of the IPCC working group II.

"Even if you live in a single country in The World , the changes in the climate system, drawn by the very large changes in The Ocean and the cryosphere are going to have an impact on the way you live your life and the opportunities for sustainable development. "

The Ways in which they can be affected, are enormous Flood damage could increase orders to two or three size. The acidification of the oceans due to increased CO2 is a threat to the coral to such an extent that even in the case of 1. 5C of warming, the disappearance of about 90%.

When the CO2 is dissolved in water it forms carbonic acid. So, the more carbon dioxide is dissolving in our oceans, the more acidic the water.

kinds of fish, as The Sea temperatures Rise . Seafood safety could be compromised because People can be exposed to elevated concentrations of mercury and persistent organic pollutants in marine plants and animals. These pollutants are free to burn the same fossil fuels that release climate-warming gas CO2.

our ability to generate electricity affect the warming, the melting of the glaciers, the change in the availability of water for Hydropower .

The melting of the permafrost could add billions of tonnes of CO2 stored in the atmosphere Permafrost as permanently huge quantities of carbon, in the permanently frozen regions of The World , such as, for example, in Siberia and in Northern Canada.

These are likely to change dramatically, with around 70% of the near-surface permafrost-set, defrost, if emissions continue to Rise .

The big concern is that this free "tens to hundreds of billions of tons" of CO2 and methane in the atmosphere by the year 2100. This would be a significant limitation on our ability to limit Global Warming in the coming centuries.

So What happens in the long run? This is an important question, and much depends on what we do in the near future to limit emissions.

however, there are some warnings in The Report that some of the changes may not be easily reversed. Data from the Antarctic at the beginning of the "irreversible Ice Sheet instability" that could see Sea Level Rise by several meters, suggest within centuries.

Climate Change force could be kind to move, their ranges "We give this Rise in Sea Level of about 2300, and the reason for this is that there is a lot of change Locked In the ice sheets and the contribution to sea-level Rise ," said Dr. Nerilie Abram of the Australian National University in Canberra, is a lead author on The Report .

"So, even in a scenario where we can reduce the greenhouse gases, future sea-level Rise are yet to plan the humans have. "
