Pollutants change He frogs Into She Frogs

Frogs that started life as male tadpoles were changed in an experiment into females by estrogen-like pollutants similar to those found in the environment, according to a new study.

The results may shed light on at least one reason that up to a third of frog species around the world are threatened with extinction, suggests the study, set to appear in the journal Environmental Toxicology and Chemistry in May.

In a laboratory at Uppsala University in Sweden, two species of frogs were exposed to levels of estrogen similar to those detected in natural bodies of water in Europe, the United States and Canada.

An Inconvenient Truth Wins Oscar for Best Documentry

“An Inconvenient Truth,” the documentary that turned former vice president Al Gore’s power-point presentation on global warming into an engaging and entertaining film, won the Oscar Sunday night. Sunday, Gore used the Oscar win not to further his political career but to boost his campaign to find solutions for global warming and other environmental problems.

“My fellow Americans,” Gore said to laughter from the crowd. “People all over the world, we need to solve the climate crisis. It’s not a political issue, it’s a moral issue. We have everything we need to get started with the possible will to act. That’s a renewable resource. Let’s renew it.”

Earlier in the evening, Gore and Leonardo DiCaprio took the stage to unveil a series of efforts the Academy of Motion Picture Arts and Sciences took to make this year’s awards more environmentally friendly. Pressed by DiCaprio about any other major announcement he might like to make, the former vice president pulled out a statement.

“My fellow Americans, I’m going to take this opportunity right here and now, to formally announce my intentions to …” Gore said before the orchestra broke in and he walked off, arm-in-arm and laughing, with DiCaprio.

Backstage, Gore put speculation to rest, saying “I do not have plans to become a candidate for office again.”

Instead, Gore said he was dedicating all his efforts to pressuring governments to act on climate-crisis issues. “It is the overriding world challenge of our time,” Gore said. “I really hope the decision by the academy to honor the work by director Davis Guggenheim and these producers will convince people who did not go see it before to see the movie and learn about the climate crisis and become a part of the solution.”

Asteroid To Hit Earth in 2036?

An asteroid may come uncomfortably close to Earth in 2036 and the United Nations should assume responsibility for a space mission to deflect it, a group of astronauts, engineers and scientists said on Saturday.

Astronomers are monitoring an asteroid named Apophis, which has a 1 in 45,000 chance of striking Earth on April 13, 2036.

Although the odds of an impact by this particular asteroid are low, a recent congressional mandate for NASA to upgrade its tracking of near-Earth asteroids is expected to uncover hundreds, if not thousands of threatening space rocks in the near future, former astronaut Rusty Schweickart said.

“It’s not just Apophis we’re looking at. Every country is at risk. We need a set of general principles to deal with this issue,” Schweickart, a member of the Apollo 9 crew that orbited the earth in March 1969, told an American Association for the Advancement of Science conference in San Francisco.

Schweickart plans to present an update next week to the U.N. Committee on Peaceful Uses of Outer Space on plans to develop a blueprint for a global response to an asteroid threat.

January 2007 Hotest On record

It may be cold comfort during a frigid February, but last month was by far the hottest January ever.

The broken record was fueled by a waning El Nino and a gradually warming world, according to U.S. scientists who reported the data Thursday.

Records on the planet’s temperature have been kept since 1880. 

Spurred on by unusually warm Siberia, Canada, northern Asia and Europe, the world’s land areas were 3.4 degrees Fahrenheit (4 degrees Celsius) warmer than a normal January, according to the U.S. National Climatic Data Center in Asheville, N.C.

That didn’t just nudge past the old record set in 2002, but broke that mark by 0.81 degrees Fahrenheit (0.56C), which meteorologists said is a lot, since such records often are broken by hundredths of a degree at a time.

“That’s pretty unusual for a record to be broken by that much,” said the data center’s scientific services chief, David Easterling. “I was very surprised.”

The scientists went beyond their normal double checking and took the unusual step of running computer climate models “just to make sure that what we’re seeing was real,” Easterling said.

It was.

“From one standpoint it is not unusual to have a new record because we’ve become accustomed to having records broken,” said Jay Lawrimore, climate monitoring branch chief.

But January, he said, was a bigger jump than the world has seen in about 10 years.

Sir Francis Walsingham

 Sir Francis Walsingham (c. 1532April 6, 1590) is remembered by history as the “spymaster” of Queen Elizabeth I of England. An admirer of Machiavelli, Walsingham is remembered as one of the most proficient espionage-weavers in history, excelling in the use of intrigues and deception to secure the English Crown. He is widely considered as the one of the fathers of modern Intelligence.  Walsingham was the first English statesman fully to embrace the challenges of the post-Reformation diplomatic world and the new European threats and alliances it offered

An Inconvenient Truth

Last night i saw Al Gore’s “An Inconvenient Truth“, A movie based on the reasons, consequences and solution of global warming. Movie revolves around a slide show presentation by Al Gore which he has presented in more than 1000 places worldwide during the past few years.

Movie also highlights Al Gore personnel efforts as US senator to solve this issue and the attitude of present US administration towards the issue. But the movie mostly portrays true facts and is an excellent effort to create a sense of awareness among the general public.

The authenticity of the facts in the movie is described on wikipedia in such remarks

“The Associated Press contacted more than 100 top climate researchers and questioned them about the film’s veracity. Because this was at the time before the film’s general release many of those surveyed had neither seen the movie nor read the book, but all 19 climate scientists who had done so said that Gore conveyed the science correctly. The U.S. Senate Committee on Environment and Public Works, chaired by Sen. Jim Inhofe, a global warming skeptic, issued a press release criticizing this article. In hofe’s statement that “global warming is the greatest hoax ever perpetrated on the American people” appears in the film.”

Movie is extremely informative and a must see.

Global Warming : Man made and Unstoppable

The world’s leading climate scientists said global warming has begun, is “very likely” caused by man, and will be unstoppable for centuries, according to a report obtained Friday by The Associated Press.

The scientists — using their strongest language yet on the issue — said now that world has begun to warm, hotter temperatures and rises in sea level “would continue for centuries” no matter how much humans control their pollution. The report also linked the warming to the recent increase in stronger hurricanes.

“The observed widespread warming of the atmosphere and ocean, together with ice-mass loss, support the conclusion that it is extremely unlikely that global climate change of the past 50 years can be explained without external forcing, and very likely that is not due to known natural causes alone,” said the report by the Intergovernmental Panel on Climate Change — a group of hundreds of scientists and representatives of 113 governments.

The phrase “very likely” translates to a more than 90 percent certainty that global warming is caused by man’s burning of fossil fuels. That was the strongest conclusion to date, making it nearly impossible to say natural forces are to blame.

What that means in simple language is “we have this nailed,” said top U.S. climate scientist Jerry Mahlman, who originated the percentage system.

The 20-page report, which was due to be officially released later in the day, represents the most authoritative science on global warming.

The new language marked an escalation from the panel’s last report in 2001, which said warming was “likely” caused by human activity. There had been speculation that the participants might try to say it is “virtually certain” man causes global warming, which translates to 99 percent certainty.

The panel predicted temperature rises of 2-11.5 degrees Fahrenheit by the year 2100. That was a wider range than in the 2001 report.
