Another Poignant Read

The NYT on renowned climate scientist Lonnie Thompson and his cohort of researchers:

Dr. Thompson, 64, is one of the most prominent of the generation of scientists who, in the latter decades of the 20th century, essentially discovered the problem of global warming. Now those scientists are beginning to age out of the field. Many of them say they grapple with the question of how hard to keep pushing themselves. Could one more finding or one more expedition help turn the tide of public awareness?

Worth a read.
