And what are we doing to it in the Anthropocene?

For anyone seeing our planet for the first time from a satellite’s perspective, worries about water might be the last thing to cross their mind. Had we first seen the planet that way; we would probably have named it ‘Water’ rather than ‘Earth.’ Looking at its clouds and ice sheets as well as its expanses of water, we would also see from that perspective that we live on a planet at just the right distance from its star to let water exist in its solid, liquid and vapor states. A few million miles farther from the sun, toward Mars, and our water would all be frozen in its solid state. A few million miles closer to the sun and the water would all be a gaseous cloud mass suffocating the planet. In neither of those situations could life as we know it exist; all life on the planet depends on water in its liquid state – but all land-based life … Read More

I said in the first post here that I’ll be focusing on ‘learning to live with the Anthropocene’ – a work-in-progress for everyone who will even acknowledge the existence of the Anthropocene. To refresh your mind on it – the Anthropocene is a new epoch in the evolution of the planet in which the human species is a factor in shaping the planet’s further evolution. This is an ‘honor’ we did not consciously seek – because who would want that kind of responsibility? But we have backed into it, as it were, like it or not – unconsciously, to be sure, and sometimes irresponsibly – but it’s where we are.  The Anthropocene follows the Holocene Epoch, which would probably only have been a 20,000-30,000-year interval, plus or minus, of warmth and greenness between epochs of Pleistocene glaciation, had we humans not inadvertently intervened with the advent of the Anthropocene. If you are looking for possible good news in the onset … Read More
