The North Pole probably looks a bit different than you would expect right now. Because, at this very moment, it's actually a lake.


The time-lapse video below comes from a webcam set up by the North Pole Environmental Observatory that has monitored the state of Arctic sea ice since the spring of 2000. Surprisingly, the pole has been melting since at least 2002, according to photos on the project's website.

July is usually the warmest month in the area, but temperatures were 1 to 3 degrees Celsius above average this year. The shallow lake you see at the pole is made of meltwater sitting on top of a layer of ice, according to the observatory.

Arctic sea ice has become a noticeable victim of climate change. The area of ice cover expands and contracts every year with the change in seasons, but last summer's minimum extent was the lowest on record and this year's maximum winter coverage was the sixth-lowest since satellite observations began in the 1970s.

CLARIFICATION: Despite having North Pole in its name, the NPEO webcam is part of a monitoring system of buoys that have drifted south of the pole. It is now at around 85 degrees north latitude and will eventually exit the Fram Strait between Greenland and Norway.




Startling footage from the North Pole, showing a lake where dense ice should be, has left people shocked by the devastating effects of global warming.

Scientists have been ringing the global warning alarm bells for years, and the cries to heed the dire warnings of melting ice caps is hitting ever closer to home.

Images from the North Pole Environmental Observatory have recorded a speedy melt this summer.

According to LiveScience the water in the newly formed lake comes entirely from melted ice and not from the water below. Water picks up more radiation from the sun than solid ice, and area is getting even warmer due to warmer temperatures. The north pole saw temperatures two to five degrees warmer than average this year.

According to Gail Whiteman, of the Rotterdam School of Management at Erasmus University in the Netherlands the north is in a vicious circle as melting ice is releasing plumes of methane into the atmosphere, speeding up the pace of global warming.

According to the National Snow and Ice Data Centre the first two weeks of July ice coverage declined 61 per cent faster than the average rate over the past three decades.
The navigation buoy centred in all the images is normally trapped in a sheet of ice all year, even during the summer melt. But this year the buoy floated freely by the middle of July leaving a lake symbolic of how global warming is ravaging through our ice caps.

At the beginning of the melt, in April, the North Pole looked like this:
  1. After one month it looked like this:
  2. After two months it looked like this: 
  3. And now it looks like this:
  1. Though the melt was evident at the beginning of the season, the lake began to form on July 13.
In 2012, this video from the observatory shows footage from a camera deployed on an ice floe for the summer. The melt at it's peak turned the ice into a patchwork of tiny ponds, then froze up again.
As the temperatures continue to rise on a regular basis, some scientists have predicted that there will be lakes forming for up to a month at a time by as soon as 2030. 
#NorthPole is now officially 'open water' after 2 wks of hot weather livescience.com/38347-north-po… http://pic.twitter.com/Rsy5IhWnzf #arctic #climatechange

Good luck world. Thanks for your ignorance. #climate #globalwarming #earth #northpole
