Although the moderate temperatures agreed in the International Plan on Climate Change have been rising, it has seen enough ice skulls to get enough of this century.

The Paris Convention for 2015 envisages countries to rise to a higher level than two-tier celsius (3.6 degrees Fahrenheit) above the industrial level and less than 1.5C.

These balloons, which reach 1.5-2 degrees by 2100, are the best scenarios of scientists based on natural resources consumption and fossil fuels, and require a radical, global lifestyle change.

For comparison, the usual way of man's business is to see if we continue to produce greenhouse gases in current volumes – we'll see the Earth's temperature up to 4C.

For decades, scientists have discovered that Glaciago and Antarctica's ice sheets have dropped, but they predict that they will not be relatively safe with the temperature rise of 1.5-2C.

However, according to a new analysis published in the journal Nature Climate Change, even global warming can cause irreversible damage to polar ice, which contributes to the catastrophic sea level rise.

"We are close to the 1.5-2C limit, which may have dramatic effects on ice sheets," said Frank Patin, director of the Earth Sciences Department, a free university in Bruxelles and a leading researcher in AFP.

The group has released data on annual temperatures, ice covering, and certain melting levels, and found that the Greenland and Antarctic ice oceans reach approximately "destructive points" at 2C.

"The presence of the point of departure indicates that the ice sheet can not be reversed – the return to the industrial-industrial situation may not be followed by an ice sheet after the crossing point," said Pattin.

In Greenland and Antarctica, glaciers have enough freezing water to raise the global sea level several meters.

The Granland ice sheet has been affected by the global sea level of 0.7 millimeters every year since the mid-1990s.

And Poles are warming faster than anywhere in the world, Greenland is only 5C in winter and 2C in the summer.

Scientists believe that hundreds of years are needed to keep up with the global warming, but Monday's research worries about the true plan to prevent humanity from leaking heat.

Many models of the 1.5-2C scenario can break down in the short run, heat the planet at a much higher level, use carbon captures and other technologies before using it for 2100 years.

The research has warned against this method, however, that the high-temperature feedback cycle would lead to a constant melting of the ice sheet, even though it subsequently rose.

For Greenland, the team says 95 percent confidence, with the ice rink dropping to above 1.8C.

"It is important to know the warmths of the levels, both for Greenland and the Antarctic, until the end of this century," says Pattin.
