The Paris Regulations will not stop crashing the ice sheet – a report – Brinkvire


The scientists issued a warning that the regulations set out in the Paris Agreement would not be enough to stop the collapse of the icebergs of Greenland and Antarctica.

According to the Paris-based agreement of 2015, countries agreed to limit global warming to less than 2dc compared to pre-industrial levels.

But a new report from the University of Victoria and Universite Libre de Bruxelles was published Climate change of nature found that both ice lists can have peaks at or slightly above the threshold of 1.5-2degC.

Professor Victor Vaughan of the University of Wellington says Tim Naish says the report is "extremely timely given the recent publication of the IPCC Special Report on global warming of 1.5degC, especially since we are close to 1.5degC."

"Without some degree of direct carbon extraction from the atmosphere, it is unlikely we will avoid it," he says.

If the ice collapse collapses, the report states that this could lead to irreversible loss of mass and drainage basins. The impact of the sea level rise would be catastrophic for New Zealand.

For New Zealand's promise in accordance with the Paris Agreement, it is necessary to reduce emissions by 30 percent below 2005 levels by 2030. It was revealed last year that the cost of the New Zealand economy to meet the goals of the Paris Agreement would be $ 1.4 billion each year in a decade.

"We are very close to triggering irreversible changes in the Earth's polar ice sheets," says Otago Christine Hulbe University professor, commenting on a new report.

"The threshold for irreversible loss of ice in Greenland and Antarctica is somewhere between 1.5 and 2dC global warming. We have already warmed up with more than 1degC.

"Even if we are scrutinizing the Paris goals and proceeding with warming, we are still committed to continuing the loss of ice during the 21st century, and therefore the continuation of sea growth."

Rob McKai, Victoria University of Wellington, notes that melting differs between the hemisphere, and the melting of Greenland controls atmospheric warming and Antarctic oceanic warming.

However, the temperature threshold for reaching these turning points in both regions is between 1.5 and 2dC, he says, "even if we meet the objectives of the Paris climate agreement, we will be extremely close to the point of no return for accelerated withdrawal.

"While this melting takes place in hundreds and thousands of years, it is obvious from this paper that the more we exceed the target of 1.5degC, the faster the accelerated wave of ice sheets will be faster."

The researchers concluded that urgent research is needed to better advance future projections.
