Scientists Explore How Best to Communicate About Climate Change


"An AGU Fall Meeting session focuses on communicating with appropriate urgency about climate change.

Don Haas, like many Earth scientists, wants to communicate effectively about the urgency of climate change. To make his point, Haas often uses an 8-foot piece of lumber.

Every gallon of gas contains about 5.5 pounds of carbon, an amount similar to that contained in an 8-foot two-by-four—a standard 8-foot-long, 2-inch × 4-inch length of wood—according to Haas, director of teacher programming at the Paleontological Research Institution in Ithaca, N.Y. Sequestering that amount of carbon by planting trees would require growing the equivalent of a two-by-four for every gallon burned. This ratio would mean growing more than 1.5 trillion pounds of wood per year to offset the 391 million gallons of gas Americans burned per day in 2017 alone, Haas said."  ～RandyShowstack @Eos
