user posted image rScientists have concluded more energy is being absorbed from the sun than is emitted back to space, throwing the Earth's energy "out of balance" and warming the globe. Scientists from NASA, Columbia University, New York, and Lawrence Berkeley National Laboratory, Berkeley, Calif. used satellites, data from buoys and computer models to study the Earth's oceans. They confirmed the energy imbalance by using precise measurements of increasing ocean heat content over the past 10 years. The study reveals Earth's energy imbalance is large by standards of the planet's history. The imbalance is 0.85 watts per meter squared. That will cause an additional warming of 0.6 degrees Celsius (1 degree Fahrenheit) by the end of this century.To understand the difference, think of a one-watt light bulb shining over an area of one square meter (10.76 square feet). Although it doesn't seem like much, adding up the number of feet around the world creates a big effect. To put this number into perspective, an imbalance of one-watt per square meter, maintained for the past 10,000 years is enough to melt ice equivalent to one kilometer (.6 mile) of sea level, if there were that much ice.

"The energy imbalance is an expected consequence of increasing atmospheric pollution, especially carbon dioxide, methane, ozone, and black carbon particles. These pollutants block the Earth's heat radiation from escaping to space, and they increase absorption of sunlight," said Jim Hansen of NASA's Goddard Institute for Space Studies, New York. He is the lead author of the new study, which is in this week's Science Magazine Science Express.

This sounds scary. Will the sun eventually burn Earth up?

No, this planet will just incinerate itself. Kinda like Venus. blush.gif
Although, maybe mother nature will respond with something like the movie Day After Tommorow, and correct the inbalance. hmm.gif Storms are a way of correcting atmosphic inbalance. Tornadoes, Hurricanes and winter weather. If you live in the Northern Hemisphere, how clear is the air and sky after a snow storm? yes.gif Never seen a deep bluer sky. Seems the global warming is something that is a cycle of nature and although the Sun is a little hotter and older than it was the last Ice Age, I think Earth itself has the ability to correct the imbalance. After all, Earth made it this far, and humans have not perturbed the climate that much. Volcanos, El Nino and other weather patterns play more of a threat than what Humans do. Let's just sit back, enjoy the warmer climate and be ready for the worst. mellow.gif would be nice to grow tomatoes in JANUARY outside in Ohio! thumbsup.gif

First the scientists were complaining about how there were holes in the ozone layer, now they are complaining that there isnt enough holes! When will the chaos end!

wacko.gif Another doomsday prediction? Geez do scientist have anything better to do then to tell us one day we will be screwed?

It seems to me that they've been grasping at straws to explain temperature and weather changes, and are, possibly, getting closer to the answer.

I think that there's simply too many people for the Earth to support - we need to stop pussy-footing around and just do it, get off planet.

It isn't like we don't have the technology..

And it isn't like we don't have the volunteers..

I bet they could get thousands of volunteers to help build a colony on Mars or any OTHER planet/body in the solar system.

I bet they could also get thousands of volunteers willing to spend the rest of their lives on a space ship in order to travel the long distance to an extra-solar planet. The idea of having the great-grandkids of the original passengers be the actual colonists isn't new.

I suppose, however, that's kind of forcing a decision on your grand-kids. geek.gif

Well its good to know that we aren`r running out of possible end of the world scenarios!

1 degree fahrenheit increase at the end of this century?

Oh no! We're doomed!

Guess I should invest in a new air conditioner soon. thumbsup.gif

Hmm, yes, sounds like science just doesn't have the answer. Oh no, shock horror!

I don't know if anybody has been watching the last couple shows of Andromeda, but they have showed a sun burning up planets and I don't want to be on Earth when that happens!

The majority of cirrus absorption and reflectivity can be accounted for by high altitude jet exhaust-induced cirrus phenomena. No mention of that, but it is a fact.
