Saturday will be a vast day of witness about climate change, from underwater on the dying coral reefs of the Pacific to the summit of melting Mont Blanc. But one of the thousands of actions planned for Connect-the-Dots day will be aimed at educating a single human being — one with power enough to make an immediate difference in the fight against climate change.

Activists in White Rock, British Columbia, will stand on the tracks across which four of Warren Buffett’s Burlington Northern coal trains are scheduled to pass en route to the Pacific, where their cargo will be shipped to China and burned in power plants. The organizers have informed police and Burlington Northern of their plans, and have pledged to be “peaceful, non-violent, and respectful of others. There will be no property destruction. We are striving to be the best citizens we can. We will stand up for what we believe is right and conduct ourselves with dignity.”
