The natural world. Looking pretty for 3.5b years.

Ice Free in 35 Years

The Arctic Ocean will be ice free during the summer as NOAA has now estimated.

NOAA researchers applied three methods of predicting when the Arctic would be nearly ice free in the summer. They have just released their predictions that the Arctic Ocean will be ice free during the summer by 2050. It might even be fully open ocean much sooner. James Overland, the lead researcher on the project commented:

“Rapid Arctic sea ice loss is probably the most visible indicator of global climate change. Tt leads to shifts in ecosystems and economic access, and potentially impacts weather throughout the northern hemisphere. The early loss of Arctic sea ice gives immediacy to the issue of climate change.”

The uses of multiple analytical approaches suggests that it is very likely that the future sea ice loss will be within the first half of the 21st century, with a possibility of major loss within the next decade or two. The research was published in Geophysical Research Letters.

Ice free in 35 years seem like a long time but in environmental terms it's a "blink of the eye".
