Tesla Powerwall Battery Economics: Almost There - "Elon Musk announced Tesla's home / business battery today. [video] tl;dr: It'll get enthusiastic early adopters to buy. The economics are almost there to make it cost effective for a wide market... That said, for large scale grid deployment (outside of the home), it still looks like flow batteries and advanced compressed air are likely to be far cheaper in the long run." [more inside]
UN Climate Report: We Must Focus On 'Decarbonization', and It Won't Wreck the Economy - "The basic message is simple: We share a planet. Let's start acting like it." [more inside]
I am a staunch believer in leading with the bad news, so let me get straight to the point. Earth, our anchor and our solitary haven in a hostile universe, is in a precarious situation. The solar system around us is rife with instability.[more inside]
The cosmos is also within us, we're made of star-stuff. We are a way for the cosmos, to know itself.
Cosmos: A Personal Voyage is a thirteen-part television series of one hour shows written by Carl Sagan, Ann Druyan, and Steven Soter, that was aired at the tail end of 1980 and was - at the time - the most widely watched series in the history of American public television.

In the year 2182 -- 172 years time -- there's a 1 in 1000 chance that we might be hit by a very large asteroid. With two centuries advance notice, will we be able to develop effective asteroid deflection techniques? [more inside]
Our amazing planet. I could study this all day.
80 percent of Americans say global warming is real and poses a threat to humanity. Which is good because if the global temperature raises by 4 degrees we're all dead. However only 44 percent would be willing to face any financial hardship in the name of a solution.
Solar System Akin to Earth's Is Discovered Any minute now, I imagine somebody at a listening station on a smaller, bluer planet a few in from this one making a minute adjustment to their equipment and promptly spraying warm stimulant-laced beverage over their console...
Reflections on a Mote of Dust "We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam."

If you want to try playing with little planets or images of them, try visiting these websites...
Webearth -- builds a LIVE vrml model of the Earth as it is right now. It draws from current composite satellite photos. Or you can play with a VRML Moon, Venus, Mars or Jupiter, if you'd prefer. (Note: this site does require a VRML 2.0 compatible plug-in, like Parallel Graphics Cortona VRML Viewer.)
Here's an oldie, but a goodie... Same concept, just not live. Earth and Moon Viewer uses various static composite satellite images from many different points of view, and it lets you zoom in and out ... (to a certain extent).
Webwide World lets you zoom in on an earth-like planet... not quite the same thrill, but the images the site produces are beautifully gem-like. And the planet it produces is huge. You'll be able explore islands off the coasts of islands off the coasts of islands.
And for more satellite image zooming pleasure, you can't beat Microsoft's Terra Server.
