Is there Still Time to Avoid Dangerous Anthropogenic Interference with Global Climate?
James Hansen, director of the GISS, examines how well humanity has responded to the warning inherent in the work of Charles D. Keeling, who passed away earlier this year. The now-famous Keeling Curve, which reveals both seasonal variability of CO2 in the Earth’s atmosphere as well as the growing effect human activity is having on atmospheric composition, has been hailed as the most rigorous and fundamental measure of global change. Hansen’s presentation will include the most current measures of the agents of global change and of climate change, including steps that have been taken to minimize and assess measurement bias. Ultimately, the metrics are beginning to paint an increasingly clear picture of humanity’s prospects for avoiding dangerous anthropogenic interference with the Earth’s climate.
