Climategate

[dmek25]

"Very likely," the IPCC said in a February 2007 report.

The report, based on the work of some 2,500 scientists in more than 130 countries, concluded that humans have caused all or most of the current planetary warming. Human-caused global warming is often called anthropogenic climate change.


• Industrialization, deforestation, and pollution have greatly increased atmospheric concentrations of water vapor, carbon dioxide, methane, and nitrous oxide, all greenhouse gases that help trap heat near Earth's surface. (See an interactive feature on how global warming works.)

• Humans are pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it.

• These gases persist in the atmosphere for years, meaning that even if such emissions were eliminated today, it would not immediately stop global warming.

• Some experts point out that natural cycles in Earth's orbit can alter the planet's exposure to sunlight, which may explain the current trend. Earth has indeed experienced warming and cooling cycles roughly every hundred thousand years due to these orbital shifts, but such changes have occurred over the span of several centuries. Today's changes have taken place over the past hundred years or less.

• Other recent research has suggested that the effects of variations in the sun's output are "negligible" as a factor in warming, but other, more complicated solar mechanisms could possibly play a role.

The Earth was formed about 4,540,000,000 years ago.

In the beginning, the Earth's atmosphere contained very little oxygen (less than 1% oxygen pressure).

Early plants started to develop more than 2 billion years ago, probably about 2,700,000,000.

Through photosynthesis, plants uptake carbon dioxide into the biosphere as organic matter, and release oxygen as a byproduct.

Through geologic time, oxygen accumulated gradually in the atmosphere, reaching a value of about 21% of atmospheric gases at the present time.

Through geologic time, surplus organic matter has been sequestered in the lithosphere as fossil organic materials (coal, petroleum, and natural gas).

Early animals (the first organisms with external shells) started to develop around 600,000,000 years ago.

Animals operate in the opposite way than plants: they take up oxygen, burn organic matter (food), and release carbon dioxide as a byproduct.

Early humans (Australopithecus anamensis) began to develop about 4,100,000 years ago.

Cool climatic conditions have prevailed during the past 1,000,000 years. The species Homo sapiens evolved under these climatic conditions.

Homo sapiens dates back to more than 400,000 years.

Estimates for the variety Homo sapiens sapiens, to which all humans belong, range from 130,000 to 195,000 years old.

The concentration of carbon dioxide in the atmosphere was as low as 190 ppm during the last Ice Age, about 21,000 years ago.

The last Ice Age began to recede about 20,000 years ago.

The agricultural revolution, where humans converted forests and rangelands into farms, began to develop about 10,000 years ago.

The agricultural revolution caused a reduction in standing biomass in the biosphere and reduced the uptake of carbon dioxide in midlatitudinal regions, indirectly contributing, however so slightly, to global warming.

The concentration of carbon dioxide in the atmosphere increased gradually from a low of 190 ppm 21,000 year ago, to about 290 ppm in the year 1900, i.e., at an average rate of 0.00478 ppm per year.

The industrial revolution, where humans developed machines (artificial animals, since they consume fuels, which are mostly organic matter), began in England about 240 years ago (1767).


In October 1999, the world's population reached 6,000,000,000, which is double that of the year 1959 (the doubling occurred in 40 years).


The world's population is currently increasing at the rate of about 80,000,000 per year (about 1.2 %).

The current world population is 6,781,000,000 (September 1, 2009).

The global fleet of motor vehicles is estimated at 830,000,000 (2006).


The global fleet of motor vehicles has been recently growing at the rate of 16,000,000 per year.

Motor vehicles (cars, trucks, buses, and scooters) account for 80% of all transport-related energy use.

The concentration of carbon dioxide in the atmosphere, which was at 290 ppm in the year 1900, rose to 316 ppm in 1959, or at an average 0.44 ppm per year.

Measurements of the concentration of carbon dioxide since 1959 (316 ppm) have revealed an increase to 387 ppm in 2009, or at an average 1.42 ppm per year.


The concentration of carbon dioxide has increased an average of about 1.8 ppm per year over the past two decades.

The concentration of carbon dioxide increased 2.87 ppm in 1997-98, more than in any other year of record.

The year 1998 was the warmest of record. The year 2002 was the second warmest (to that date). The year 2003 was the third warmest (to that date). The year 2004 was the fourth warmest (to that date). The year 2005 equaled 1998 as the warmest of record. The year 2007 equaled 1998 as the second warmest of record. The ten warmest years have occurred in the twelve-year period 1997-2008.

About 75% of the annual increase in atmospheric carbon dioxide is due to the burning of fossil fuels.

The remaining 25% is attributed to anthropogenic changes in land use, which have the effect of reducing the net uptake of carbon dioxide.

Anthropogenic changes in land use occur when forests are converted to rangelands, rangelands to agriculture, and agriculture to urban areas.

Other patterns of land degradation--deforestation, overgrazing, overcultivation, desertification, and salinization--reduce the net uptake of carbon dioxide, indirectly contributing, however slightly, to global warming.

Here is a nice Truth - Myth column from John Stossel from a couple years ago. I remember being forced to watch 20/20 when i was a real little kid with my parents (back in the day when people only had 1 tv). The only part of the show i liked was when John Stossell did his reporting. He doesnt spin anything, he simply offers facts and common sense and lets viewers make their own decision. And it worked for him and he became famous. You don’t really see many people like him, who dont force their objective into their reporting or journalism.

http://abcnews.go.com/2020/story?id=3061015&page=1

Again Fox decided to report this issue. NBC, ABC, and CBS chose not to probably doesn’t vibe with their objective. Pretty sad.

Nice read . In 6th grade , we had a group come in with oxygen mask's/tanks , chemical suit and firemans jacket and told us " by the time you get out of high school , you will have to wear the O mask/tank during daytime because of the smog" .... graduated 1982 I would love to run into them today and kick their a$$es !!

"So what should we do about the threat of global warming?

First, calm down.

Second, if the world is warming, it is much more reasonable to adjust to it, rather than try to stop it. If sea levels rise, we can build dykes and move back from the coasts. It worked for Holland.

Farmers can plant different crops or move north. Russian farmers farmed northern Siberia for centuries. When the area became cold and desolate, the farmers moved south.

Far better to keep studying global warming, let the science develop and adjust to it if it happens, rather than wreck life as we know it by trying to stop it. "

some people just hate logic, not me

I wish the water would rise 4' because then I'd have water front property instead of water view.

I thought all the scientist said we where headed to global cooling? Whats up with that.

Well last night one of the major networks did a story on climategate. They did not give any details about what was really in the emails and only made it out to be something that crazy anti global warming people where talking about on the internet. Its like they ran the story because they had but did not want to do.

they ran the same type of story on headline news(a sister network of cnn), this morning, it was bs, i tried to explain to my fiancee what it really was but seemed not to care, she beleives in global warming btw

When it came up both my wife and her friend said they knew nothing about it and after the story still dodn't know anything about it.

^and they probably say it's all lies and won't bother to actually check it out

More than 1,700 scientists have agreed to sign a statement defending the "professional integrity" of global warming research. They were responding to a round-robin request from the Met Office, which has spent four days collecting signatures. The initiative is a sign of how worried it is that e-mails stolen from the University of East Anglia are fueling skepticism about man-made global warming at a critical moment in talks on carbon emissions.

One scientist said that he felt under pressure to sign the circular or risk losing work. The Met Office admitted that many of the signatories did not work on climate change.

What's Going to Happen?

A follow-up report by the IPCC released in April 2007 warned that global warming could lead to large-scale food and water shortages and have catastrophic effects on wildlife.

• Sea level could rise between 7 and 23 inches (18 to 59 centimeters) by century's end, the IPCC's February 2007 report projects. Rises of just 4 inches (10 centimeters) could flood many South Seas islands and swamp large parts of Southeast Asia.

• Some hundred million people live within 3 feet (1 meter) of mean sea level, and much of the world's population is concentrated in vulnerable coastal cities. In the U.S., Louisiana and Florida are especially at risk.

• Glaciers around the world could melt, causing sea levels to rise while creating water shortages in regions dependent on runoff for fresh water.

• Strong hurricanes, droughts, heat waves, wildfires, and other natural disasters may become commonplace in many parts of the world. The growth of deserts may also cause food shortages in many places.

• More than a million species face extinction from disappearing habitat, changing ecosystems, and acidifying oceans.

• The ocean's circulation system, known as the ocean conveyor belt, could be permanently altered, causing a mini-ice age in Western Europe and other rapid changes.

• At some point in the future, warming could become uncontrollable by creating a so-called positive feedback effect. Rising temperatures could release additional greenhouse gases by unlocking methane in permafrost and undersea deposits, freeing carbon trapped in sea ice, and causing increased evaporation of water.

So dmek25 you want us to believe all this from IPCC scientest that have been shown to be a fraud? How can anyone take anything they report now as serious factual information?
