In early 2010, BBC Earth took a behind-the-lens look at some of the scientific information used to help make the BBC’s Frozen Planet series. Producers at the network’s Natural History Unit in Bristol led us to the findings of the National Snow and Ice Data Center, where sea ice scientists have been carefully analyzing the conditions of the Arctic’s frozen wilderness. We collaborated with designer Rupert Burton to bring this data to life. The two infographics below illustrate how the sea ice’s age and extent have fluctuated over the past 20 years, influenced by changes in weather, winds, and currents.

TIME IS RUNNING OUT!

We have an ambitious $350,000 online fundraising goal this month and it's truly crunch time: About 15 percent of our yearly online giving usually comes in during the final week of the year, and in "No Cute Headlines or Manipulative BS," we explain why we simply can't afford to come up short right now.

The bottom line: Corporations and powerful people with deep pockets will never sustain the type of journalism Mother Jones exists to do. And advertising or profit-driven ownership groups will never make time-intensive, in-depth reporting viable.

That's why donations big and small make up 74 percent of our budget this year. There is no backup to keep us going, no alternate revenue source, no secret benefactor. If readers don’t donate, we won’t be here. It's that simple.

And if you can help us out with a donation right now, all online gifts will be matched thanks to an incredibly generous matching gift pledge.
