Yesterday, on the 20th anniversary of his initial testimony to Congress about human impact on the earth's climate, Dr. James Hansen was celebrated for his work as a "hero of science and our planet." (To read more about the 1988 hearing, check out yesterday's post from Luis).
Although it was a moment to honor his work, Dr. Hansen was quick to bring the conversation back to the science and the need for action now. As he put it, "This is not a time to celebrate."
