Climatologists are now reporting for the first time ever that the concentration of carbon dioxide in the atmosphere has reached 400 ppm, the highest such concentration in several million years. The last time carbon dioxide levels were that high, the seas ultimately rose 60 to 80 feet higher than they are today.

The ongoing debate over the "Age of Man" is a healthy one, but I am more concerned about what we are actually doing to mitigate and cope with the Anthropocene. And, here again, I come back to the importance of empowering women.

The time has come for the ecological century. Nature does not respond to our interdependence with it by trying to minimize itself out of existence, but instead by growing and flourishing. Good design does the same.

Now you can add another data point supporting the notion of the Anthropocene -- caffeine in near shore ocean and estuarine waters.

Has the time really come when people are the dominant force on the planetary surface?

If our values change, we might use science and technology to save us. If our failed values persist, science and technology will only press our accelerator.

We need a new, non-burning energy economy, a way of reducing population, and a way of replacing the delusion of infinite growth. That's what we need. Or the population will be adjusted in the usual way: with shortages, bullets, and bombs.

Mass extinction is finally fighting its way back into the news cycle, thanks to recently scary reports on climate change.

For the first time in human history, we have to respond as a single species to crises of our own making. Until now, this kind of unified effort only happened in science fiction when space aliens invaded Earth.
