Two years ago I took these photos. The top in this series is a 4 mile long iceberg in the Ross Sea; the middle, a photo from the helicopter of frozen pools and volcanic dirt; the last photo a super-close view of the icy surface of Lake Hoare. I’ve been missing this beautiful continent a lot lately and thinking about how important the next few years of policy will be in preserving it.

People often ask if we see evidence of climate change working in Antarctica. The short answer is yes: the shrinking of ice shelves has increased 70% in the last decade. Check out this story on NPR.

“It’s toppling the domino. You don’t push quite hard enough and nothing happens. You push a little harder and it falls over.”
