The Arctic is melting faster than ever before, and scientists say that the ice is melting more quickly than ever since satellite records began more than two decades ago.
A new study published in the journal Science suggests that the melting is happening faster than any other time in recorded history, and the Arctic’s sea ice is at a record low.
It is also the first time in nearly 200 years that the Arctic has seen the ice decline in record-breaking ways, the study’s authors wrote.
The study found that the sea ice had dropped by less than half a percent since the mid-1970s.
This is not a trend that can be attributed to climate change.
The melting of Arctic sea ice has occurred for at least 150 years and the recent ice loss is a direct result of human activities, according to a press release from the National Snow and Ice Data Center.
Researchers at the University of Washington in Seattle and the National Center for Atmospheric Research in Boulder, Colorado, looked at satellite records dating back to the early 1900s, and found that during that time, Arctic sea levels rose about 1.5 meters (3.6 feet) per year, which was slower than any time in the past 100 years.
The study also found that Arctic sea level rise accelerated in the summer of 2015, when temperatures soared to a record high.
But the ice-free summer of 2016 was the second warmest summer in recorded human history, at more than 1.6 meters (4.2 feet).
The authors said that the rapid rate of ice loss in the Arctic “was unprecedented in the last 2,000 years,” and that the rate of Arctic ice loss “was not consistent with warming.”
This is a long-term trend that we cannot change.
This is not something that can easily be reversed, and it will not happen over the next few decades, said John Nielsen, an ice-cap expert at the Carnegie Institution of Washington.
Scientists have been trying to find a solution to the ice loss for decades.
A few years ago, scientists announced a plan to reduce the amount of ice in the North Atlantic Ocean by about 30 percent.
But that plan was called off in December, and now the plan is back on.
Ice-free summers in the Pacific Northwest have been an annual event for about two decades, but scientists have yet to come up with a solution that would allow the ice to continue to melt faster.
It’s unclear how much longer that will last.
“I think we’ve reached the tipping point,” Nielsen said.
The Arctic’s ice loss has been happening for centuries, but its impact on sea levels is not fully understood, Nielsen said, adding that it could be decades before the ice melts completely.
Scientists are concerned that the new study may not be the final word on the topic.
In fact, the new research comes with a caveat: “The authors caution that the current sea-level rise is likely to continue in the near term, and that future ice-loss rates could be impacted by other environmental and climate factors,” the news release from National Snow & Ice Data center said.
