ALERT: NAVIGATING
THE IPCC

The U.N. Intergovernmental Panel on Climate Change will release part of their fifth assessment report on September 27.

To prepare our meteorologists, Climate Central is creating "Navigating the IPCC," a collection of tools to help you understand and communicate the report findings, including new graphics, social media interactives, and video and accompanying script (for you to track and localize the story).

SAVE THE DATES: Climate Central will be offering two different webinars around this event. We are hosting the first one on Monday, September 23. We are offering access to a second one, hosted by the U.N. Foundation and The Climate Group on Friday, September 27, featuring IPCC scientists live from Sweden.

RSVP to bplacky@climatecentral.org to save your spot.

Story Highlights

  • Any day now, the ice that covers the Arctic Ocean will shrink to its smallest area of the year.

  • This year's loss won't be quite as dramatic as last year's record, but it's still pretty significant.

  • The annual Arctic ice loss has been getting more severe, thanks to global warming.

  • Compared with the median ice cover from 1981-2010, this year’s loss comes out to approximately 8 times the land area of Florida.

Any day now, the ice that covers the Arctic Ocean will shrink to its smallest area of the year. It happens every year at about this time from the cumulative seasonal effects of higher temperatures and 24-hour-a-day sunshine in the polar regions. But the loss of ice has been getting more severe, thanks to global warming.

Last year, Arctic ice covered less area than at any time since satellites began monitoring the region back in the late 1970s. This year’s ice loss won’t be quite as dramatic, but it’s still pretty significant. The graphic above shows that compared with the median ice cover from 1981-2010, this year’s loss comes out to approximately 8 times the land area of Florida. And while each year isn’t necessarily less icy than the year before, the downward trend is clear — and the plunge is happening faster than the majority of computer models predicted.

There is a natural cycle of melting and freezing that happens every year. However, the effects of global warming are starting to alter the natural melting for the worse – creating a vicious cycle. When the ice shrinks, its bright, white, reflective surface is replaced by darker ocean. The darker ocean absorbs heat and makes it more difficult for the ice to refreeze in winter. In recent years, the winter ice has also gotten thinner which makes it more prone to melting the next season. Finally, more open water means winds and ocean currents can push more ice out into the North Atlantic where storms can break it up, further reducing the amount of sea ice.

Nobody knows when the summer in the Arctic will be totally ice-free, but on the basis of observed trends and computer models it could happen within just a few decades—or even less. That will make polar bears unhappy, but it could affect us, too. Some climate scientists think that the warming Arctic has altered the jet stream in ways that are bringing us more extreme weather events, while others seem not to detect as strong a linkage with extremes. That’s an area of active research at this point, but it is a fact that the Arctic is warming faster than any other part of the globe—and it’s not crazy to think that this large change just has to have an effect on the rest of the planet.
