The World Meteorological Organization reports arctic ice has melted this year to its lowest-recorded level.
The first 10 months of 2012 were the ninth warmest in recorded history, according to the climate agency.
Arctic ice has diminished by 16 percent from 2007.
"This winter, obviously, the ice will form again, but it will be fresh ice, it will be thin ice, so ice that will be more vulnerable to future melting," Michel Jarraud, secretary general of the WMO, said. "So definitely the message here is that the trend is not only continuing, but accelerating with respect to the melting of the Arctic ice and this is linked to the chance in the global, in the temperature."
Meanwhile, a Germany climate agency reports that sea levels are rising 60 percent faster than UN projections and could actually threaten low-lying areas like Miami, Fla. The Potsdam Institute for Climate Impact Research says global warming has not slowed down despite efforts to cut carbon emissions.
