It provides the best available scientific knowledge to empower people, communities and governments to tackle the unprecedented transitions in all aspects of society, including energy, land and ecosystems, urban and infrastructure, as well as industry." NEWS CONFERENCE IN PROGRESS (SOUNDBITE) (English) IPCC WORKING GROUP 1 CO-CHAIR, VALERIE MASSON-DELMOTTE, SAYING: "Permafrost, frozen soil and rock, is thawing with the potential of adding more greenhouse gases to the atmosphere. Even if global warming was limited to well below 2 degrees (Celsius), about one-quarter of the near-surface permafrost will thaw by 2100. If our greenhouse gases emissions continue to increase strongly, around 70 percent near-surface permafrost could be lost." NEWS CONFERENCE IN PROGRESS (SOUNDBITE) (English) IPCC WORKING GROUP 2 CO-CHAIR, HANS-OTTO PORTNER, SAYING: "The ocean has taken up between 20 to 30 percent of these carbon dioxide emissions producing global warming, and continued uptake will exacerbate ocean acidification by 2100. An ocean that is warmer, more acidified and losing oxygen has implications for" marine life, its distribution and productivity."

This report highlights also the urgency of timely, ambitious, coordinated and enduring action. What is at stake is the health of ecosystems, wildlife and importantly, the world we leave for our children."

Scientists behind a landmark study of the links between oceans, glaciers, ice caps and the climate delivered a stark warning to the world on Wednesday (September 25): slash emissions or watch cities vanish under rising seas, rivers run dry and marine life collapse.
Days after millions of young people demanded an end to the fossil fuel era at protests around the globe, a new report by a U.N.-backed panel of experts found that radical action may yet avert some of the worst possible outcomes of global warming.
But the study was clear that allowing carbon emissions to continue their upward path would upset the balance of the great geophysical systems governing oceans and the frozen regions of the Earth so profoundly that nobody would escape untouched.
"This new special IPCC report highlights the urgency of prioritizing timely, ambitious and coordinated action to address widespread and enduring changes in the ocean and cryosphere," IPCC Co-Chair Debra Roberts said.
Finalised on Tuesday (September 24) in a last 27-hour session of talks in Monaco between authors and representatives of governments, the report was the culmination of two years of work by the U.N.-backed Intergovernmental Panel on Climate Change (IPCC).
Compiled by more than 100 authors who crunched 7,000 academic papers, the study documented the implications of warming oceans, fast-melting ice sheets in Greenland and Antarctica and shrinking glaciers for more than 1.3 billion people living in low-lying or high mountain regions.
The report projects that sea levels could rise by one metre (3.3 ft) by 2100 -- ten times the rate in the 20th century -- if emissions keep climbing. Looking further forward, the rise could exceed five metres by 2300.
In the Himalayas, glaciers feeding ten rivers, including the Ganges and Yangtze, could shrink dramatically if emissions do not fall, hitting water supplies across a swathe of Asia.
Thawing permafrost in places such as Alaska and Siberia could release vast quantities of greenhouse gases, potentially unleashing feedback loops driving faster warming.
"What is at stake is the health of ecosystems, wildlife and importantly, the world we leave for our children," IPCC Vice Co-Chair Ko Barrett said.
