HERE'S WHAT I THINK
Global warming is inevitable
Today's global warming is a result of past carbon dioxide emissions. Tomorrow's will be a result of today's.
To reverse global warming we would need to return to the emission levels we had before it all started. This is unlikely to happen...

- Global warming? No. Global Climate change? Yes. Global climate change has been happening ever since the beginning of the earth. Multiple ice ages have happened and thawed.
Humans have, if anything at all, an extremely small effect on the "warmth" of the planet. The Industrial Revolution put more CO2 into the atmosphere than we "modern" people could ever imagine. There's nothing drastic mentioned about changing climates, rising sea levels, or freezing cold.
Global Warming, as it is called, was made by politicians. Politicians who do not have any background in real science. The politicians are only interested in making money through their carbon emission credits and taxes.

- I think global warming is real. Mankind has a definite impact on the environment, from the toxic cleaners we use in our homes daily, the large amount co2 emmissions generated daily and a host of other contaminants. How can it not effect the enviroment! I recall back in the early 60's when I picketed Ford factories and other factories to clean up thier emissions. Luckily we have come along way since. Additionlly I recall when when the Cleveland's Cuyahoga River burst into flames from all the toxins in it and Lake Erie was once dead. I did a lens about the first Earth Day in 1970 with some interesting facts, and what we can do to sustain our environment. I hope you can visit.

- I think if nothing is done now in 70 or 80 some years New York and a lot of other cities will be under 30 or so feet of water. People that deny Global warming really need to wake up and get a clue. Do you know how really bad it's going to be?
I live in Washington State and the weather is really getting strange. We had snow in April. We also had for the most part a mild winter and they have been getting more mild over the last 20 years at a rate that really shouldn't be happening if things were all good.

More on Solar Variation
Solar variations refer here to changes in the amount of total solar radiation and its spectral distribution. There are periodic components to these variations, the principal one being the 11-year solar cycle (or sunspot cycle), as well as aperiodic fluctuations.Satellite observations of total solar irradiance Solar activity has been measured by satellites during recent decades and estimated using 'proxy' variables in prior times. Scientists studying climate change are interested in understanding the effects of variations in the...
Delayed Warming
Today's global warming is caused by past emissions. Future warming will be caused by today's.
We would need to do more than just stop the increase in emissions. We would need to go back to the pre-warming level of emissions.
It also may take centuries for natural processes to remove the extra CO2 from the atmosphere. So our current emissions will continue to affect the climate for centuries.
The following chart shows emissions for the past 200 years. Would we need to return to 1990 emissions? Or do you think we would need to return to 1950 emissions? Please post your thoughts below.

- I don't thing we're going to unless there is no other choice- our entire economy is based on high usage of fossil fuels and consuming everything we can get our hands on. It won't be until it actually collapses for everyone on the planet that we'll change, because there won't be any other way.

- Fact 1: Water vapor is a far more potent and far more abundant greenhouse gas than CO2. The CO2 contribution is trivial. People assume it's bad with very little evidence to support their assumption.
Fact 2: CO2 follows a diminishing curve. The means the 2nd unit of CO2 increase has less effect than the 1st. The third is even lower. For example, 100 units of CO2 increases temp by 1 degree, the next 100 increases it by half degree, the next by a quarter, and so on.
Fact 3: According to NASA the warmest years were before 1950 and the last few years have shown a flat temperature scale. So the spike seems to have little effect.
Fact 4: According to ice cores the historic temperature records show temperatures increasing 800-1200 years before CO2 increased.
More on Global Warming
Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) between the start and the end of the 20th century. The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation. The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanism produced most of the warming from pre-industrial times to 1950 and had a small...

This is one example of positive feedback: Phenomena which speed up global warming after a small increase in temperature.

- Top scientists from over 100 countries have agreed global warming is real, is manmade, and is affecting our world. If they're wrong, we still get a cleaner, more energy-efficient world that isn't so reliant on fossil fuels if we act to stop it. If they're right, and we do nothing, we're in trouble. There is no downside to trying to stop global warming.

- The problem with projections into the future is that they are based on bad data, poorly written models that are incomplete, and bias from the lastest politically correct sicentists to prove the point.
And these guys are brainwashing all the students in engineering, so it is a self perpetuating problem.

- These cooling and warming trends have gone on for mellenia.
The "Medieval Climate Optimum" records temperatures ~2 degrees warmer than now. Do you suppose industry back then was the cause?
Global warming is due primarily to solar cycles that alternately cause decreases or increases in solar wind.
Strong solar winds stave off streams off cosmic rays that would otherwise slam into the ocean's surface, releasing vast quantities of water vapour (the most important of the greenhouse gases) and CO2.
Al Gore and his henchmen just want to empty our wallets of our hard earned money. A serious side-effect of all this: We leave Africa in poverty by denying them the tools needed for development.
Dr. S. Fred Singer (Professor Emeritus of Environmental Sciences at the University of Virginia states, "There is no dispute at all about the fact that even if punctiliously observed, (the Kyoto Protocol) would have an imperceptible effect on future temperatures - 1/20th of a degree by 2050."

More on Effects of Global Warming
== Overview ==
Over the last hundred years or so, the instrumental temperature record has shown a trend in climate of increased global mean temperature, i.e., global warming. Other observed changes include Arctic shrinkage, Arctic methane release, releases of terrestrial carbon from permafrost regions and Arctic methane release in coastal sediments, and sea level rise.
Global average temperature is predicted to increase over this century, with a probable increase in frequency of some extreme weather events, and changes in rainfall patterns. Moving from global to regional scales, there is increased uncertainty over how climate will change. The probability of warming having unforeseen consequences increases with the rate, magnitude, and duration of climate change. Some of the physical impacts of climate change are irreversible at continental and global scales. Sea level is expected to rise 18 to 59 cm (7.1 to 23.2 inches) by the end of the 21st century. Due to a lack of scientific understanding, this sea level rise estimate does not include all of the possible contributions of ice sheets. Slowing of the Meridional Overturning Circulation is very likely to occur this century, but temperatures in the Atlantic and Europe will probably still be higher due to global warming. For a global warming of 1-4°C (relative to 1990-2000), there is a moderate chance that partial deglaciation of the Greenland ice sheet would occur over a period of centuries to millennia. Including the possible contribution of partial deglaciation of the West Antarctic Ice Sheet, sea level would rise by 4?6 m or more.
The impacts on human systems of climate change will probably be distributed unevenly. Some regions and sectors are expected to experience benefits while others will experience costs. With greater levels of warming (greater than 2-3°C, relative to 1990 levels), it is likely that benefits will decline and costs increase. Low-latitude and less-developed areas are probably at the greatest risk from climate change. With human systems, adaptation potential for climate change impacts is considerable, although the costs of adaptation are largely unknown and potentially large. Climate change will likely result in reduced diversity of ecosystems and the extinction of many species. Adaptation potential for biological and geophysical systems is estimated to be lower than that for human systems.

Game theory is a branch of applied mathematics that is used in the social sciences, most notably in economics, as well as in biology, engineering, political science, international relations, computer science, and philosophy. Game theory attempts to mathematically capture behavior in strategic situations, in which an individual's success in making choices depends on the choices of others. While initially developed to analyze competitions in which one individual does better at another's expense (zero sum games), it has been expanded to treat a...
YOUR TURN!

Global warming is inevitable
Fetching blurbs now... please stand byYes, you're right!
Danfree says:
Yes Global warming is inevitable and so is Global Cooling, but... who defines Global Warming. When the new Denver Airport was built in the '90's, they found fossils of palm trees and ferns. These are displayed while you are waiting to go through the security check point.
Who is to say that, palm trees are not normal for Denver and that what we are in now is a Global Cooling Cycle and we are just warming up to normal.
Cyclical climate changes happens along with other stuff. The problem is the do gooders want to regulate and tax us back into the stone age in the name of Global Warming.
Do you really think China, India, and other poor countries are going to cut back on their carbon emissions to go along with some untested theory?
And what about natural occurences. You can not control or predict those. If weather people can't tell me the weather next week or month, why should I believe their predictions for 50 years from now. And did you notice that hurricane predictor guy did not do too well in 2007 even though increased and more powerful hurricanes are suppose to be the result of Global Warming.
And the people on Discovery/History (I get them confused as to where I saw something) channel are saying the world is over due for a massive volcano eruption from several places and that could send the world into an mini ice age.
Not an endorsement but this guy has a free report entitled "The Truth about Global Warming."

Global warming is inevitable, as is global cooling.
Global climate is not in stasis, it fluctuates wildly throughout the history of the Earth. This was going on for billions of years before our technology came into being, and it will continue long after we are gone, whether into extinction or just into the casmos.

Of course global warming is inevitable. The same as global cooling is inevitable. Humans have a bad habit of judging future predictions on its own small lifetime. The problem with modern projections is that there is not enough scientific data going back far enough to make proper assumptions. Another fact a lot of people seem to ignore is that in the last 50 years we have lost nearly 50% of our global rainforests. Trees are the major carbon fixing entities on our planet. It's like a human losing one of their lungs!

We are actuslly at a peak now, and within two to three years will see temperatures drop, based on the solar flares and other effects, such as el nino. . .
But by then, we may have a bunch of silly laws costing us trillions of dollars.
I am all for moving away from fossil fuels, not becuase we are killing the earth, but becuase it is jsut the right thing to do - renewable is ALWAYS better than consumption.

The world has been getting hotter than any cycle change has ever peaked before. Record breaking temperatures have been seen more years in a row lately, than in history. Pollution is worse than ever. Air Quality continues to degrade. If the current energy usage continues, it is only a matter of time before there is devastating results. There is a huge amount of renewable energy available, that could replace fossil fuels and help immensely with the environmental problems.

The earth itself will make changes that will 'overpower' whatever we do. For example, a huge volcanic eruption would put an immediate end to the warming, but swing us in the other direction. We still would benefit by simplifying our lives, reducing the global transport of unnecessary goods, and so on, but in the end the planet will triumph over us for a change.

Just for the record - I don't deny that some warming has occured. However, I do deny two things:
1) That warming is catastrophic. There is ZERO evidence to support this. My the way, the hockey stick graphic below has been totally discredited by real climate scientists.
2) That warming is a bad thing. There is also ZERO evidence to support the "Warming is Bad" idea. All the available evidence supports the opposite idea, that warming is good.
Some real climate science including a critique of "The Most Terrifying Video..."
Four part video debunks warming.
Snide remarks by Orsen Scott Card. (What's that you say? He isn't a scientist? True, but then neither are Al Gore or the IPCC Bureaucrats.)
It's a scam - by someone who studies weather and climate for a living.
IPCC Commentary - we'll get more bang for the buck feeding hungry kids than fighting warming.

So yeah, there's been some warming, it's mostly good, and the "Warming Is Bad And We're ALL Doomed!!!" ideas are total and complete rubbish.
