Time Is Running Out To Control Climate Change, U.N. Report Says

Climate change: Unprecedented action is required to curb temperature rise, says UN panel report

UN climate report warns of warmer earth; demands unprecedented efforts

The report from the Intergovernmental Panel on Climate Change, the United Nations body for assessing the science related to climate change, revealed that limiting global warming to 1.5 degrees Celsius "would require rapid, far-reaching and unprecedented changes in all aspects of society", according to a statement announcing the climate change report.

Limiting warming to "well below" 1.5 degrees hotter than pre-industrial levels was the promise made by governments all over the world at the Paris climate talks in 2015. Extreme temperatures, rainfall, and sea levels have been pushed higher. But even a 1.5°C rise in temperature will be threatening to India.

The report will provide the framework of discussion for the Katowice Climate Change Conference in Poland in December when governments review the Paris Agreement to tackle climate change.

Tropical nations most affected by climate asked the UN to create a report showing the difference in impact between a 1.5 degree Celcius (2.7 degrees F) and a 2.0 C (3.6 degree F) increase.

He said: "It is in our own interests to have effective climate action - and all must act".

Reduce carbon emissions by 45%

.

The report is based on an analysis of more than 6,000 scientific papers, reviewed by climate scientists from 40 countries.

Allowing the global temperature to temporarily exceed or "overshoot" 1.5ºC would mean a greater reliance on techniques that remove Carbon dioxide from the air to return global temperature to below 1.5°C by 2100. But IPCC also adds that the effectiveness of CO2-capturing technologies is still unproven on a large-scale.

"The next few years are probably the most important in human history", Debra Roberts, head of the Environmental Planning and Climate Protection Department in Durban, South Africa, and an IPCC co-chair, told AFP.

The Intergovernmental Panel on Climate Change, meeting in South Korea, issued a report with 91 authors and editors from 40 countries declaring that there's now a 12-year window to make "far-reaching and unprecedented changes" to avert dramatic effects of global warming.

The Nobel Prize-winning organisation said that the world was well off track in its goal of limiting global temperature rise to below 1.5ºC and heading for 2ºC or more.

"We have a monumental task in front of us, but it is not impossible", Mahowald said earlier.

Another says an ice-free Arctic Ocean during summer could happen once per century with a 1.5 degree rise as opposed to at least once per decade if temperatures go up two degrees. "Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate". WWF calls on leaders to accelerate climate action immediately'. Right now it's hard, but not impossible, to contain climate chaos.

Joyashree Roy, a professor of economics at Jadavpur University and a co-author of the IPCC report, says: "We have found that the burden of global warming will fall disproportionately on the poor who are not responsible for the problem if we don't meet (the) 1.5 degrees target". That will cause coastlines to become inundated and storms more severe, intensifying poverty in coastal regions and islands, particularly in the tropics. "There will also be heat stress in cities and air quality will deteriorate due to high fossil fuel use".

Matthew Spencer, Oxfam's director of campaigns and policy said: 'Climate change has set our planet on fire, millions of people are already feeling the impacts, and the IPCC is clear that things could get much worse without immediate action.

"I just don't see the possibility of doing the one and a half" and even 2 degrees looks unlikely, said Appalachian State University environmental scientist Gregg Marland, who isn't part of the United Nations panel but has tracked global emissions for decades for the U.S. Energy Department.

"E$3 ven with erroneous attribution of extreme weather/climate events and projections using climate models that are running too hot and not fit for objective of projecting 21st century climate change, the IPCC still has not made a strong case for this massive investment to prevent 1.5C warming", she said on her Climate Etc. blog.
