What have you done today to lower your impact?

We are washing away the foundations of our existence on every front. It is high time we move from crashing about on the planet like a bull in china shop and find a way to go forward with intent. We must find systems of living based on sustainability. The systems and tools exist, it is up to each of us to adopt them.

Yowza! Sounds like science fiction but it isn't

Check out this article over on celsias by Jeanne Roberts. It's starting to feel like a movie starring Kevin Costner.

Antarctic Ice Shelf "Hanging by a Thread", and What it Means to You

Here's an excerpt,

"Now, to make matters worse, geophysicists from the University of Toronto warn that the increasingly unstable West Antarctic Ice Sheet (WAIS) could lead to significantly higher sea level rises, and such changes will be highly variable as well, affecting primarily North American and nations in and along the southern Indian Ocean (Indonesia, the Maldives, and Madagascar).

Estimates suggest rises up to 16.5 feet, which is the value of the total volume of water locked up in the WAIS. However, warns study author and geophysicist Jerry X. Mitrovica, the estimate may fall shy because it ignores three significant effects: sea levels fall near a melting ice sheet, but rise progressively at greater distances; earth rebounds when an ice sheet melts, pushing more water into the ocean, and; melting of an ice sheet as large as the WAIS may cause the earth's rotational axis to shift, potentially as much as 1,640 feet from its present location - an alteration in the earth's geophysical plane that could shift water from the southern oceans to the Indian Ocean and northward toward North America."
