Thin Ice should correct the notion that climatologists are just number-crunching geeks. Mark Bowen finds that the field’s cutting edge isn’t in the lab, but on the dangerously exposed faces of the world’s highest mountains, where scientists defy boredom and death to document global warming.

Thin Ice focuses on the exploits of Lonnie Thompson, the relentless visionary behind the high-altitude climatology movement, one of the most promising areas of global warming research. For 30 years, he’s led expeditions to “every blank on the map he could find,” from the Andes to Kilimanjaro, to drill for ice cores, frozen time capsules that lock in air, dust, and pollution of climates past, and offer solid (literally) evidence of human impacts on the environment. Thompson has now spent more time in the “death zone” above 20,000 feet than almost anyone alive. Even his chief rival admits that Thompson’s insistence that the real climatological action is atop glaciers, not at the poles, has earned him a place “in the ranks of our great explorers.”

Bowen tells Krakaueresque tales of Thompson’s trials (avalanches, altitude sickness, torrential storms turning solar panels into kites, valuable samples plummeting down vertical faces), alternating with a meticulous, if sometimes labored, history of the science. Thin Ice is an occasionally hair-raising picture of an overlooked and surprisingly risky quest that will appeal to science buffs and armchair adventurers alike.

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.
