Cause of global warming

The phenomena. Historically, all of the Earth's climate changes were attributed to natural forces such as volcanic eruptions, Earth's orbital changes, and the amount of released solar energy. That changed with the introduction of the Industrial Revolution late in the 18th century, when human activities began to alter the global climate and environment.

The Industrial Revolution

The onset of the industrial revolution has paved way for the advancement of human technology. As more people relied on technology, numerous tools and devices were invented to make life easier for men. However, the emergence of these inventions has also resulted in the dependence of man to energy. The influx of energy usage from fossil fuels, coal, oil or gas has also resulted in the inception of human-induced rapid climate change. The demand for energy around the world is currently at more than 80% of the world-wide energy demand. Most of this is from fossil fuels such as gas, oil, and coal. Since the energy demand is too high, there hasn't any other alternative source yet with this magnitude which could replace fossil fuels in the short or medium term. Thus the drastic increase in the emission of CO2 (carbon dioxide) within the last 30 years caused by burning fossil fuels has been identified as the major reason for the change of temperature in the atmosphere.

Greenhouse gases and global warming

Greenhouse gases regulate our climate by trapping heat and holding it in a kind of warm-air blanket that surrounds the planet. They are necessary for keeping the Earth's temperature warm enough to support life. This occurrence is scientifically called the "greenhouse effect." The problems related to global warming which we have encountered for decades started when human activities added more greenhouse gases into the atmosphere which disrupt and speeds up the natural process thereby warming the planet to more than the right temperature. Scientists revealed that as the concentrations of these gases continue to increase in the atmosphere, the Earth's temperature will also continue to climb above past levels eventually making the Earth become less habitable for humans, plants and animals. Burning fossil fuels by driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas are just some of the human activities that emit this carbon dioxide into the atmosphere in overwhelming proportion.

Global warming and its consequences

For decades, the rapid pace at which the temperature has risen had already resulted in many negative impacts to humans and the environment and this has created a world-wide concern. Most scientists believe that the warming of the climate will lead to more extreme weather patterns which may accelerate species extinction, influence the length of seasons, results in poor yield of crops, trigger flooding in costal lines, sets off abrupt climate changes and results to more frequent and violent storms.

It just sort of happened. All as a result of the two-year back-and forth I've had with the YouTube community about this video and its follow up marathon "How It All Ends."So now "What's the Worst That Could Happen? A Rational Response to the Climate Change Debate" is available from Amazon and other sellers through the links at www.gregcraven.org, as well as your local bookstore (I hope!).Check it out if you're intrigued by the argument in this video.On Amazon: http://snurl.com/kjpvpTrailer for the book: http://www.youtube.com/watch?v... the critics are saying: http://www.gregcraven.org/en/t... a 25-page preview: http://www.gregcraven.org/en/t... the press: http://www.gregcraven.org/en/t... REASON THE COMMENTS ARE CLOSED ON THIS VIDEO is that most of the criticisms of what's presented here have been addressed by the bruisingly thorough 7-hour How It All Ends video project, the discussion is happening over there. I spent months combing through literally tens of thousands of critical comments to find every single objection, criticism, "Yeah but," and "You missed a spot" that I could to this video. You might find the results interesting, and hopefully, helpful: http://www.youtube.com/view_pl... can post comments there. But to tell the truth, the conversation has moved even farther along, since the criticisms to those videos gave rise to the book, which now has its own discussions going at http://www.manpollo.org/forums...

Climate news...(Please read before the denier with all the sock puppet accounts censors it, or shouts it down like the loser troll he is)...Texas drought forces a town to sip from a truck.Beach is one of the first four subdivisions, made up of about 1,100 people, in drought-stricken Burnet County to run so low on water that it had to be hauled in by truck..New York Times4 Feb 2012

Hmmm? So much for?"the science is definitive, there can be no questioning of the science!!" REALLY? Ok. I'm not questioning the science. BUT. The science seems to be changing? And almost every new study coming out seems to be doing the same thing. So the results of the studies are changing.Hmmm? Seems I remember saying fairly recently that the FACTS are starting to turn AGAINST the AGW apostles. And like I also said? THEY DON'T LIKE IT. Oh well? It IS what it IS.
101orson101 (November 30, 1999 at 12:00 am)
BUT! Everything they try to make all of us believe IS exactly what so many of the AGW proponents have said THEY MUST DO. Make everything sound MUCH WORSE tha it ever really will be. Check the quotes from all the main players and designers of the UN IPCC scam? They have ALL said the same things. "We have to grossly exagerate everything just to get people to listen to us."If that is NOT scaremongering, never mind LIEING! Then I have never seen anyone LIE in my entire 64 years.
101orson101 (November 30, 1999 at 12:00 am)
OK! So what was the comment reguarding all of this by the climate alarmist groupy scientists?" The new data does not mean that concerns about climate change are overblown in any way."YOU DECIDE! THEY scaremongered the Himalayas were melting. THEY ARE NOT! Their charts show MASSIVE global warming. The NUMBERS say BULLSHIT! THEY said the oceans would inundate all the major cities by 2050. WHAT? With arounf 2.5 to 3 inches of water? Climate change IS happening. Just NOT like they try to say.
101orson101 (November 30, 1999 at 12:00 am)
But even just useing the NASA numbers? EVEN they show absolutely NO MORE than an average temp rise of 0.522 C over 32 years. 1/2 of ONE degree C.NOW? Take all this information and look again at that most recent study released just a few days ago, that says we have had NO ICE loss from the Himalayas in the last ten years?? And the study was done by the University of Colorado. NOT some climate yahoo.
101orson101 (November 30, 1999 at 12:00 am)
Now if you look at and believe the IPCC hockey stick? They would have you believe it was by a MASSIVE amount. Just look at their charts? BUT? Actual readings tell us it was by no more than from 0.131C to 0.522C. And that was from all the way back from 1980 to NOW.These are NOT my figuers. They are actual readings taken from the two sites. ALL I did was put them next to each other and note the actual differences. And the apparent bias the NASA numbers consistently showed across the board.
101orson101 (November 30, 1999 at 12:00 am)
But remember? We are still only talking about LESS than 0.2C above or below that mean baseline. In the decade of the 90's? Once again UAH said we ran - 0.034C BELOW and NASA said we ran +0.321 ABOVE. STILL only 0.3C compared to the mean baseline. In the decade of the 2000's? Uah said we ran +0.131C ABOVE and NASA said we ran +0.522C ABOVE. SO? Here's the question. IF we ran ONLY +0.30 or so all those years from 1979 to 2011? The decade WAS some of the hottest years ever. BUT? By how much?
101orson101 (November 30, 1999 at 12:00 am)
And even through the entire 32 years the same bias was constant. The 80's decade bias was 0.329C. The 90's decade bias was 0.356C. And the 2000 decade bias was 0.391C. Now all of these measurements used the same mean baseline established from around 1960 to 1990. So any + or - was simply above or below that mean baseline.Now here's where it get's really interesting. In the decade of the 80's? UAH says we ran -0.142C DOWN to that baseline and NASA said we ran +0.187C UP.
101orson101 (November 30, 1999 at 12:00 am)
Now I did another interesting cross study. I downloaded all the actual reported temps from BOTH NASA and UAH. Then built a side by side comparison with all their temp reading from 1979 to 2011 ALL taken on the same dates. Take a guess what I found?I compared them all by the same date, yearly, and by the decade. Pretty interesting chart when it was done. Almost every single date showed a 0.3C bias UPWARDS from UAH. And that followed through to every decade doing the same thing.
Effects of global warming

Climate Change. Scientific researches have already revealed that the effects of global warming in the 21st century and beyond are expected to be disastrous. Many of these changes are already under way. Recent studies conducted by Working Group II of the United Nations' Intergovernmental Panel on Climate Change (IPCC), states that the increased greenhouse gas concentrations are very likely to increase the Earth's average temperature, influence precipitation, and some storm patterns as well as raise sea levels. In addition to this, the United States National Academy of Sciences has warned that "greenhouse" warming and other human alterations of the earth system may increase the possibility of large, abrupt, and unwelcome regional or global climatic events.

Projected Impacts of Global Warming

A board organized by the U.S National Research Council in June 2006 expressed a "high level of confidence" that Earth as we know it today has experienced the hottest climate for the last 400 years, and possibly even the last 2,000 years. Studies have shown that, for the last century, there has been an increase in the average global surface temperature of roughly 0.3-0.6 degree Celsius (0.5-1 degree Fahrenheit). This global warming will potentially lead to future large-scale and possibly permanent effects at continental as well as global scales. The likelihood, magnitude, and timing is uncertain and contentious but some examples of projected impacts that will occur are more frequent and more intense heat waves, droughts, severe storms, more floods, degraded water quality, and increased spread of infectious diseases. If for the past 100 years such overwhelming effects were observed while the globe warmed up by an estimated average of merely 0.6 degree Celsius (1 degree Fahrenheit), this phenomenon will likely get worse by the year 2100. By that time, temperatures could increase by 6 degree Celsius (11 degree Fahrenheit).

Global Warming and the Society

The effects of global warming will be felt in every region worldwide and at all levels of society. Reports from the United Nations' Intergovernmental Panel on Climate Change (IPCC) confirmed with 90 percent certainty that global warming is now inevitable and humans are primarily accountable for a significant portion of the heat-trapping greenhouse gases that have caused global temperatures to rise significantly since the middle of the 20th century. It also made clear that while poor people worldwide will suffer most from the effects of global warming, no person on Earth will escape its consequences.
