Infographics: How Arctic Sea Ice is Changing

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.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

Headshot of Editor in Chief of Mother Jones, Clara Jeffery

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
