This summer we were fortunate to share a blog series brought to us by Arctic scientists — experts working to study and understand the habitat, species and ecological changes happening at the top of the world. It’s rare for those of us who live a ways away to see a glimpse of this vibrant, and beautiful place, but our blog series aimed to bring YOU into the Arctic Ocean. We shared scientist stories about how truly special this place is. And how important the Arctic is, not only to the animals and people that thrive there, but to the overall health of our ocean. If you missed reading the blogs, we encourage you to check them out now. Here are just a few of the reasons we think you’ll enjoy reading the series.

The National Snow and Ice Data Center (NSIDC) recently made a preliminary announcement that Arctic sea ice on September 16 had melted to about 1.32 million square miles, or just 24 percent of the surface of the Arctic Ocean. This is the lowest seasonal ice coverage since satellite measurements began in 1979. Although ice should start building back up now as the Arctic heads into winter, any newly formed sea ice will be relatively thin and more prone to melting in the coming summer. The Arctic is our planet’s air conditioner, and it plays a key role in regulating global climate. Its cold air and water help drive atmospheric and ocean currents that regulate temperatures worldwide.
NSIDC scientist Julienne Stroeve said, “Recent climate models suggest that ice-free conditions may happen before 2050, though the observed rate of decline remains faster than many of the models are able to capture.” This means the actual melting of sea ice is happening faster than what recent climate models predict and an ice-free Arctic could happen even sooner.
