About David Grinspoon:

David Grinspoon is an astrobiologist, award-winning science communicator, and prize-winning author. He is a senior scientist at the Planetary Science Institute and adjunct professor of astrophysical and planetary science at the University of Colorado. Grinspoon's research focuses on climate evolution on Earth-like planets and potential conditions for life elsewhere in the universe. He is involved with several interplanetary spacecraft missions for NASA, the European Space Agency and the Japanese Space Agency. In 2013 he was appointed as the inaugural chair of astrobiology at the U.S. Library of Congress where he studied the human impact on Earth systems and organized a public symposium on the Longevity of Human Civilization.

His new book "Earth in Human Hands" was named a “best science book of 2016” by NPR’s Science Friday. His previous book “Lonely Planets: The Natural Philosophy of Alien Life ” won the PEN Center USA Literary Award for Nonfiction. Grinspoon has been recipient of the Carl Sagan Medal for Public Communication of Planetary Science by the American Astronomical Society.

Global Climate Strike, Student Action


Kids in 123 countries strike to protect the climate

“This movement had to happen, we didn’t have a choice.”


Via Vox

An estimated 1.4 million young people in 123 countries skipped school Friday to demand stronger climate policies in what may be one of the largest environmental protests in history.

In the Age of the Anthropocene


“We are living in the middle of a mass extinction today, but none of us feel that urgency, or that it really is so.”

The 8 Million+ Species We Don’t Know

By Edward O. Wilson

The most striking fact about the living environment may be how little we know about it. Even the number of living species can be only roughly calculated. A widely accepted estimate by scientists puts the number at about 10 million. In contrast, those formally described, classified and given two-part Latinized names (Homo sapiens for humans, for example) number slightly more than two million. With only about 20 percent of its species known and 80 percent undiscovered, it is fair to call Earth a little-known planet.


  • To effectively manage protected habitats, we must also learn more about all the species of our planet and their interactions within ecosystems.


The best-explored groups of organisms are the vertebrates (mammals, birds, reptiles, amphibians, fishes), along with plants, especially trees and shrubs. Being conspicuous, they are what we familiarly call “wildlife.” A great majority of other species, however, are by far also the most abundant. I like to call them “the little things that run the world.” They teem everywhere, in great number and variety in and on all plants, throughout the soil at our feet and in the air around us. They are the protists, fungi, insects, crustaceans, spiders, pauropods, centipedes, mites, nematodes and legions of others whose scientific names are seldom heard by the bulk of humanity. In the sea and along its shores swarm organisms of the other living world — marine diatoms, crustaceans, ascidians, sea hares, priapulids, coral, loriciferans and on through the still mostly unfilled encyclopedia of life.

Do not call these organisms “bugs” or “critters.” They too are wildlife. Let us learn their correct names and care about their safety. Their existence makes possible our own. We are wholly dependent on them.
