Why Marco Rubio Needs To Know That The Earth Is Billions Of Years Old – Forbes

November 22, 2012 Leave a comment
UNIQUE PICTURE: Earth as seen from the outer S...Florida Senator Marco Rubio, who many political observers think has a strong shot to be a 2016 Presidential candidate, just finished a lengthy interview with GQ that you can read here. One thing that struck my interest here, as someone who often reports on science, was Rubio’s answer when he was asked the question, “How old do you think the Earth is.”
In response, Rubio told GQ that, “I’m not a scientist, man. I can tell you what recorded history says, I can tell you what the Bible says, but I think that’s a dispute amongst theologians and I think it has nothing to do with the gross domestic product or economic growth of the United States. I think the age of the universe has zero to do with how our economy is going to grow. I’m not a scientist. I don’t think I’m qualified to answer a question like that. At the end of the day, I think there are multiple theories out there on how the universe was created and I think this is a country where people should have the opportunity to teach them all. I think parents should be able to teach their kids what their faith says, what science says. Whether the Earth was created in 7 days, or 7 actual eras, I’m not sure we’ll ever be able to answer that. It’s one of the great mysteries.”

BBC – Future – Science & Environment – Sucking CO2 from the skies with artificial trees

October 9, 2012 Leave a comment

It may be a colourless, odourless and completely natural gas, but carbon dioxide is beginning to cause us a lot of problems. It only makes up a tiny fraction of the atmosphere (0.04% of all the gas by volume – or 395 parts per million) but it has a huge effect on the Earth’s temperature. That’s because unlike nitrogen or oxygen, carbon dioxide molecules absorb the Sun‘s heat rays even though they let light rays pass through, like a greenhouse.

Scientists are looking at ways to modulate the global temperature by removing some of this greenhouse gas from the air. If it works, it would be one of the few ways of geoengineering the planet with multiple benefits, beyond simply cooling the atmosphere.

Every time we breathe out, we emit carbon dioxide just like all other metabolic life forms. Meanwhile, photosynthetic organisms like plants and algae take in carbon dioxide and emit oxygen. This balance has kept the planet at a comfortably warm average temperature of 14C (57F), compared with a chilly -18C (0F) if there were no carbon dioxide in the atmosphere.

In the Anthropocene (the Age of Man), we have shifted this balance by releasing more carbon dioxide than plants can absorb. Since the industrial revolution, humans have been burning increasing amounts of fossil fuels, releasing stored carbon from millions of years ago. Eventually the atmosphere will reach a new balance at a hotter temperature as a result of the additional carbon dioxide, but getting there is going to be difficult.

Kepler telescope team finds 11 new solar systems | TECHNOLOGY News

January 28, 2012 Leave a comment

NASA’s planet-hunting Kepler space telescope has found 11 new planetary systems, including one with five planets all orbiting closer to their parent star than Mercury circles the Sun, scientists say.

The discoveries boost the list of confirmed extra-solar planets to 729, including 60 credited to the Kepler team. The telescope, launched in space in March 2009, can detect slight but regular dips in the amount of light coming from stars. Scientists can then determine if the changes are caused by orbiting planets passing by, relative to Kepler’s view.

Kepler scientists have another 2,300 candidate planets awaiting additional confirmation.

None of the newly discovered planetary systems are like our solar system, though Kepler-33, a star that is older and bigger than the Sun, comes close in terms of sheer numbers. It has five planets, compared to our solar system’s eight, but the quintet all fly closer to their parent star than Mercury orbits the Sun.

The planets range in size from about 1.5 times the diameter of Earth to five times Earth’s diameter. Scientists have not yet determined if any are solid rocky bodies like Earth, Venus, Mars and Mercury or if they are filled with gas like Jupiter, Saturn, Uranus and Neptune.

‘Mystery City’ Revealed By ISS Time-Lapse Video Turns Out To Be Enormous Oil Field

Internet forums exploded after an astonishing time-lapse video of the Earth taken from the International Space Station revealed more that was first thought – a mystery city that ‘shouldn’t have existed’.

The dramatic video displays the Earth illuminated by the green glow of the Aurora Borealis, and cities represented as bright spots of electric lights.

Taken by the crew of the ISS between August and October 2011, the clip was an immediate online hit.

But one of the thousands of people who saw the video noticed what appeared to be a mystery city, located near Edmonton in Canada, that did not appear on any map.

The strange collection of lights in North Dakota, USA, appeared to be equivalent in size to cities as large as Calgary and Minneapolis, but seemed impossible to identify.

The “City” in question comes into view at about the 34-second mark.

NASA – 2012: Beginning of the End or Why the World Won’t End?

NASA has named the Roland Emmerich blockbuster 2012 the most scientifically-flawed film ever made. Apart from the abuse of neutrino particles and the myth of the Mayan Calendar ending in 2012, one of the things that has most upset NASA is having to set up a special website to counteract all the claims made by the film.

Among other bits of helpful advice, we find the following:

Question (Q): Are there any threats to the Earth in 2012? Many Internet websites say the world will end in December 2012.

Answer (A): Nothing bad will happen to the Earth in 2012. Our planet has been getting along just fine for more than 4 billion years, and credible scientists worldwide know of no threat associated with 2012.

Q: What is the origin of the prediction that the world will end in 2012?

A: The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012. Then these two fables were linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012 — hence the predicted doomsday date of December 21, 2012.
