Is Planet Earth at Dusk?

Read this carefully.......for it will affect not you but your kids and grandkids - and generations thereafter.

"A few weeks ago, our foremost climatologist, NASA's Jim Hansen, submitted a paper to Science magazine with several co-authors. The abstract attached to it argued--and I have never read stronger language in a scientific paper--"if humanity wishes to preserve a planet similar to that on which civilization developed and to which life on earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm." Hansen cites six irreversible tipping points--massive sea level rise and huge changes in rainfall patterns, among them--that we'll pass if we don't get back down to 350 soon; and the first of them, judging by last summer's insane melt of Arctic ice, may already be behind us.

So it's a tough diagnosis. It's like the doctor telling you that your cholesterol is way too high, and if you don't bring it down right away, you're going to have a stroke. So you take the pill, you swear off the cheese, and, if you're lucky, you get back into the safety zone before the coronary. It's like watching the tachometer edge into the red zone and knowing that you need to take your foot off the gas before you hear that clunk up front."

This frightening assessment of where our planet is at appears in a piece in The Nation, here.

It's not at all friendly in United's sky!

More than apt commentary in The Guardian (with video)on United Airline's outrageous conduct so widely reported around the world....

It has become apparent that America’s airlines, much like America’s president, have absolutely no shame. They seem to care only about profit and treat the people they supposedly serve like chattel, cattle or criminals.

This week’s installment of airlines reaching new lows is brought to you by United – you know, the people who spendtens of millions of dollarson fancy adverts urging you to “Fly the Friendly Skies”, while seemingly going out of their way to make the skies as unfriendly as possible. The story has been everywhereover the last 24 hours and you’ve probably seen thegraphic video. United overbooked a flight and, having only realized this after the flight had boarded, tried to force a few randomly selected passengers off. One man refused to vacate the seat he paid for and, thus, had a reasonable expectation of sitting in. Security office…
