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.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
