Lou Rought: Yes of course there are natural climate drivers, and there are natural cycles that cause ice ages. But the current warming (slow as it seems to be) is *much* faster than any past natural climate changes. The evidence that it is caused by humans burning fossil fuels is very secure.

Bernadette Roel: Try this. Put three ice cubes in a glass of water, then mark the level of the water with a piece of tape or something. Now wait till the ice cubes melt and see where the water level is. Higher? Lower? The same? Are you surprised?
Warren Kotter: Sea levels might raise a millimeter or two.Here is truth about global warming:Global warming is one-half of the climatic cycle of warming and cooling. The earth's mean temperature cycles around the freezing point of water.This is a completely natural phenomenon which has been going on since there has been water on this planet. It is driven by the sun.Our planet is curren! tly emerging from a 'mini ice age', so is becoming warmer and ! may return to the point at which Greenland is again usable as farmland (as it has been in recorded history).As the polar ice caps decrease, the amount of fresh water mixing with oceanic water will slow and perhaps stop the thermohaline cycle (the oceanic heat 'conveyor' which, among other things, keeps the U.S. east coast warm). When this cycle slows/stops, the planet will cool again and begin to enter another ice age. It's been happening for millions of years.The worrisome and brutal predictions of drastic climate effects are based on computer models, NOT CLIMATE HISTORY. As you probably know, computer models are not the most reliable of sources, especially when used to 'predict' chaotic systems such as weather.Global warming/cooling, AKA 'climate change':Humans did not cause it.Humans cannot stop it....Show more
Coleman Senn: There is not the slightest chance that the Climatologists don't understand the role of the natural cycles. It's like suggesting NASA doesn't ! understand the role of gravity.
Nell Dipiero: In the past global warming and cooling has been caused by natural cycles.One of the things that keeps our planet at a habitable temperature and one of the contributors to global warming in the past are the greenhouse gases. Many of these occur naturally but in the last 200 years our activities have resulted in the emission of far more of these gases than can be handled by natural cycles.The result is that the excess gases have accumulated in the atmosphere. Natural greenhouse gases maintain a more or less steady temperature, the human ones add to the natural warming and lead to excessive warming - what we call global warming.GW is being pinned on people, cars, power plants etc because these are sources of greenhouse gases. One of the main sources is the burning of fossil fuels - coal, oil and gas.Global warming won't trigger an ice age for a very, very long time yet. Our position within the natural cycles that trigger ! ice ages puts us at abou 70 million years to go. Before the onset of a! nother ice age there will be intense warming of the planet, by about another 20°C or so. Even if we did everything possible to cause global warming we wouldn't be able to cause this sort of temperature rise for thousands of years.One possibility, that's all it is, is that global warming could trigger a change on the ocean current that transports warm water from the Caribbean to northwestern Europe, this current keeps parts of Europe warmer than they would be otherwise. If GW disrupts this particular current there will be cooling in some parts of Europe and a mini ice age will develop over the course of a few thousand years.If you'd like anything explaining in more detail or require a technical explanation please add more details or email me....Show more
Jackelyn Archut: The CO2 goes into the air and which then we are living in a green house. But people exaggerate too much. Don't worry about it because people say cut cars and carpool but no where or any how that i! s possible unless someone creates a non polluting car which hasn't been created yet.
Carter Edstrom: titanic you may go down in history in worse shape than the ship. I have been working on just such an idea a car that uses pollution as fuel/oxidizer even if it puts out pollution it will be from the pollution that was already there, therefore, it doesn't make any pollution it's self (it's partially based on nature too).
William Vickerman: This is an issue that is often misunderstood in the public sphere and media, so it is worth spending some time to explain it and clarify it. At least three careful ice core studies have shown that CO2 starts to rise about 800 years (600-1000 years) after Antarctic temperature during glacial terminations. These terminations are pronounced warming periods that mark the ends of the ice ages that happen every 100,000 years or so. Does this prove that CO2 doesn't cause global warming? The answer is no.The reason has to do with the fa! ct that the warmings take about 5000 years to be complete. The lag is o! nly 800 years. All that the lag shows is that CO2 did not cause the first 800 years of warming, out of the 5000 year trend. The other 4200 years of warming could in fact have been caused by CO2, as far as we can tell from this ice core data. The 4200 years of warming make up about 5/6 of the total warming. So CO2 could have caused the last 5/6 of the warming, but could not have caused the first 1/6 of the warming.It comes as no surprise that other factors besides CO2 affect climate. Changes in the amount of summer sunshine, due to changes in the Earth's orbit around the sun that happen every 21,000 years, have long been known to affect the comings and goings of ice ages. Atlantic ocean circulation slowdowns are thought to warm Antarctica, also.From studying all the available data (not just ice cores), the probable sequence of events at a termination goes something like this. Some (currently unknown) process causes Antarctica and the surrounding ocean to warm. This process a! lso causes CO2 to start rising, about 800 years later. Then CO2 further warms the whole planet, because of its heat-trapping properties. This leads to even further CO2 release. So CO2 during ice ages should be thought of as a "feedback", much like the feedback that results from putting a microphone too near to a loudspeaker. In other words, CO2 does not initiate the warmings, but acts as an amplifier once they are underway. From model estimates, CO2 (along with other greenhouse gases CH4 and N2O) causes about half of the full glacial-to-interglacial warming.So, in summary, the lag of CO2 behind temperature doesn't tell us much about global warming. [But it may give us a very interesting clue about why CO2 rises at the ends of ice ages. The 800-year lag is about the amount of time required to flush out the deep ocean through natural ocean currents. So CO2 might be stored in the deep ocean during ice ages, and then get released when the climate warms. Since as we know warm wa! ter can not hold as much gas as cold water so it releases C02. And it t! akes along to warm up because the ocean is so large and water has a high heat capacity.O and some food for thought:Al Gore’s Personal Energy Use Is His Own “Inconvenient Truthâ€Gore’s home uses more than 20 times the national average Last night, Al Gore’s global-warming documentary, An Inconvenient Truth, collected an Oscar for best documentary feature, but the Tennessee Center for Policy Research has found that Gore deserves a gold statue for hypocrisy. Gore’s mansion, located in the posh Belle Meade area of Nashville, consumes more electricity every month than the average American household uses in an entire year, according to the Nashville Electric Service (NES). In his documentary, the former Vice President calls on Americans to conserve energy by reducing electricity consumption at home. The average household in America consumes 10,656 kilowatt-hours (kWh) per year, according to the Department of Energy. In 2006, Gore devoured nearly 221,000 kWhâ€"more tha! n 20 times the national average. Last August alone, Gore burned through 22,619 kWhâ€"guzzling more than twice the electricity in one month than an average American family uses in an entire year. As a result of his energy consumption, Gore’s average monthly electric bill topped $1,359. Since the release of An Inconvenient Truth, Gore’s energy consumption has increased from an average of 16,200 kWh per month in 2005, to 18,400 kWh per month in 2006. Gore’s extravagant energy use does not stop at his electric bill. Natural gas bills for Gore’s mansion and guest house averaged $1,080 per month last year. “As the spokesman of choice for the global warming movement, Al Gore has to be willing to walk the walk, not just talk the talk, when it comes to home energy use,†said Tennessee Center for Policy Research President Drew Johnson.

Now we can solve the current crises which is much worse.Join intelligent people from around the world tackling the problem of global warming through two important goals1. Control of carbon emissions worldwide. The developed world should take the lead and limit the carbon emissions through taxation and carbon offsetting and lower the standard of living of the common people to a r! easonable level that the developing world can easily reach within the next 20 years.2. Reducing the population of the human race which if not controlled by a UN body will increase the burden of an already over burdened planet and stress our resources and our environment far beyond the breaking point. This will have to be done by the developing third world in however manner they deem appropriate. We must reduce our population from 6 billion to 2 billion by the year 2050 to have a sustainable future.Together the world CAN SOLVE THIS PROBLEM. It is not out of our reach. We just need to know HOW WE ARE CAUSING AGW and every person should be given a realistic picture. All this fuzzy pink stuff in the media doesn't give you the facts or the solutions that people must know NOW.

Houston Venezia: The sea le! vel will rise, but not because of ice burgs. Ice burgs are already in the water so the volume wouldn't change essentially.The reason the sea will rise though is because glaciers from mountains will melt and flow down the rivers and into the sea.
Valentine Michaud: He says he will unblock you if you unblock him. You can view his question by logging out, viewing it, then logging back in.
Chris Coggins: What you refer to is the theory of buoyancy, a foating object displaces it down weight in water, sea ice has already displaced its own weight, so when it melts nothing happens, just like a glass with ice in.If all the sea ice melted sea level would not change, but land ice has not displaced its own weight, so if that melts it will add to sea levels. If all the glaciers, perma frost and greenland ice melted the estimated volume of ice divided by the surface of the ocean equates to a 5mm rise in sea level.If the antarctic ice where to melt, the estimated volume divid! ed by the area of the sea results in around 6m, though it would actually be less as the seas area would increase with level. This is the very worst case and would not occur without significent warming far greater than that predicted and it would take thousands of years to happen.There is also another issue at play, which is thermal expansion caused by the warming of the sea. As sea temperature increase the theory is that the level rises, though only by a small amount with each degree.So based on the above there is a theory that warming will result in raised sea levels, however, there are some other theories. One is that with warming evaporation increases which keeps sea levels constant, the increased evaporation will result in increased snow fall at the poles and increased ice mass.What we do know based on observations is that sea levels have barely changed over the last few hundred years of warming and recently have been falling rather than rising, but temperatures have be! en decreasing aswell.I believe that warming will result in increased se! a levels but in the range of 10s of mm rather than Al Gores and the IPCC predictions of several meters in the next 100 years. The original IPCC report predicted a 1m rise by this point in time and it hasnt happened so it just demonstrates know yet fully knows what will happen
Susan Rambo: Global warming is so debatable at this time that you wouldn't want to call it a theory leave alone a fact.

So I go along with global warming to help save the animals....Show more
Rona Ising: One of the most important environment cha! nges now in progress is a buildup of atmospheric CO2. Undoubtedly, the added CO2 in the atmosphere is coming from the burning of fossil fuels, the cutting down of forests and the wastage of soil humus. Moreover, other gases are now being added, with similar properties. The main outcome of the buildup is likely to be a change of climate, notably toward greater warmth.
Barrett Alosa: What if instead of your speculation you tried to listen to real experts.NOAA: Greenhouse Gases Likely Cause of Near-record U.S. Warmth Last YearGreenhouse gases likely accounted for over half of the widespread warmth across the continental United States in 2006, according to a new study that will be published Sept. 5 in Geophysical Research Letters, a publication of the American Geophysical Union.Last year's average temperature was the second highest since recordkeeping began in 1895. The team found that it was very unlikely that the 2006 El Nino played any role, though other natural facto! rs likely contributed to the near-record warmth. When average annual te! mperature in the United States broke records in 1998, a powerful El Niño (a warming of the surface of the east tropical Pacific Ocean) was affecting climate around the globe. Scientists widely attributed the unusual warmth in the United States to the influence of the ongoing El Niño. The research team, led by Martin Hoerling at the National Oceanic And Atmospheric Administration's (NOAA) Earth System Research Lab in Boulder, Colo., also found that greenhouse gas increases in Earth's atmosphere enhanced the probability of U.S. temperatures breaking a record in 2006 by approximately 15-fold compared to pre-industrial times. The authors also estimate that there is a 16 percent chance that 2007 will bring record-breaking warmth. "We wanted to find out whether it was pure coincidence that the two warmest years on record both coincided with El Niño events," Hoerling said. "We decided to quantify the impact of El Niño and compare it to the human influence on temperatures throu! gh greenhouse gases." Preliminary data available in January 2006 led NOAA to place that year as the warmest on record. In May 2007, NOAA revised the 2006 ranking to second warmest after updated statistics showed the year was .08 degrees Fahrenheit cooler than 1998. The annual average temperature in 2006 was 2.1 degrees Fahrenheit above the 20th Century average and marked the ninth consecutive year of above-normal U.S. temperatures. Each of the contiguous 48 states reported above-normal annual temperatures, and for the majority of states, 2006 ranked among the 10 hottest years since 1895. Using data from 10 past El Niño events observed since 1965, the authors examined the impact of El Niño on average annual U.S. surface temperatures. They found a slight cooling across the country. To overcome uncertainties inherent in the data analysis, the team also studied the El Nino influence using two atmospheric climate models. The scientists conducted two sets of 50-year simulations! of U.S. climate, with and without the influence of El Niño sea-surfac! e warming. They again found a slight cooling across the nation when El Niño was present. To assess the role of greenhouse gases in the 2006 warmth, the researchers analyzed 42 simulations of Earth's climate from 18 climate models provided for the latest assessment by the Intergovernmental Panel on Climate Change (IPCC). The models included greenhouse gas emissions and airborne particles in Earth's atmosphere since the late 19th century and computed their influence on average temperatures through 2006. The results of the analysis showed that greenhouse gases produced warmth over the entire United States in the model projections, much like the warming pattern that was observed last year across the country. For a final check, the scientists compared the observed 2006 pattern of abnormal surface temperatures to the projected effects of greenhouse-gas warming and El Niño temperature responses. The U.S. temperature pattern of widespread warming was completely inconsistent with ! the pattern expected from El Niño, but it closely matched the expected effects of greenhouse warming. "That attribution was not confirmed at the time," Hoerling said. "Now we have the capability, on the spatial scale of the United States, to better distinguish natural climate variations from climate changes caused by humans."...Show more
Mayola Sylva: Part of it may be a cycle. But don't worry, climatologists are well-aware of climate cycles. The fundamental science behind global warming is not in dispute. Here's the logic, which is not refuted by anyone with any expertise:(1) We are simply thickening the atmosphere by burning millions of years worth of fossil fuels in a span of about two centuries. By burning those fuels, we are transforming a solid (hydrocarbons) into a gas (CO2) by oxidizing hydrocarbons.(2) The thickening of the atmosphere with CO2 causes planets to become warmer, much like a giant blanket. We have two examples in the solar system. Mars is! too cold for Earth life because it has a very thin atmosphere, and Ven! us is too hot for Earth life because it has a very think atmosphere full of CO2.Now, there's no doubt that other factors affect climate: proximity to the Sun, Earth's orbit, brightness of the Sun, etc. No one disputes that either, but skeptics latch on to these excuses to justify the status quo.But the reality is that our increasing the amount of planetary CO2 by 40-50% (and there are a few other greenhouse gases to be concerned about, but CO2 is the one humans most influence) will cause the Earth to get warmer, on average. And this change is taking place much more rapidly than geologic cycles....Show more
Gaston Edgcomb: I''m not sure if I fully grasped your idea correctly but from what I get I'm pretty sure your theory is right
Debora Rinderer: Okay unblock reciprocated.My question you are referring to was making light of the comment by those researchers stating warming will be "irreversible" which should mean that ice ages can't happen any more. Feel free ! to comment.
Clay Lipira: I don't know the physics as well as I should, but ice that's FLOATING already in water should displace about as much water as it will contribute to the total volume when it melts. Ice that's resting on LAND, however, does not displace any water.So when * already floating * sea ice melts, the level of the oceans remains virtually the same. However, when ice on land melts and the water flows into the ocean, the level of the ocean will rise -- just because there's more water there.To take your example of the ice in a glass of water, when we melt a glacier on LAND, it's as if we've picked up some ice from the refrigerator, or from a completely different glass, and we've put it into your glass. That means we've added to the total volume of water in the glass, whether it's frozen or not. And so the water in the glass will rise.That's what we do when we take ice that's been sitting on top of the Swiss Alps, say, or on some mountain top in Antarcti! ca, and we either melt it and allow the water to flow into the ocean, o! r if we plop the ice itself into the ocean. That's totally different from melting ice that's been floating in the ocean already.Why is this important in terms of global warming? The ice now captured in mountain glaciers around the world -- in the Alps, Andes, Himalayas, the various ranges of Alaska, etc. -- is now resting on LAND, not on water. So is most of the ice in the gigantic Greenland ice cap.So is most of the ice -- not all of it, but most of it -- in Antarctica.As global warming occurs, the prediction is that many or most of the mountain glaciers around the world will melt -- in fact, many of them are already melting now.If warming continues long enough, and average temperatures rise high enough, an increasing volume of the Greenland ice cap will melt as well. Finally, if the temperature gets really high, we should see melting of some significant fraction of the Antarctic ice sheet.This sort of melting will cause water/ice that's now supported on LAND to flow in! to the OCEANS, and it should raise ocean levels quite a lot. There is enough ice in the Greenland ice cap, for instance, to raise average sea/ocean levels by something like 6 meters or 20 feet if it all melts and flows into the ocean.There is enough ice in the West Antarctic ice sheet alone to raise average sea levels by another 5 meters or about 16 feet, if it all melts.Taking all of Antarctica into account, there is enough water trapped in the total Antarctic ice cap to raise sea levels by around 60 meters or more -- more than 190 feet -- if the ice of the whole continent were to melt. However, none of the scientists expect this to happen for hundreds or even thousands of years.In addition to melting, there's another climate-related risk connected to glacier ice that's now resting on land. Ice is heavy, and in most cases glacier ice flows slowly downhill in the direction of the oceans under the pressure of gravity. In Greenland, scientists now think there's a risk of w! armer temperatures causing the rate of flow towards the ocean to speed ! up, even if temperatures don't get hot enough to melt the entire ice cap.Why? When surface ice starts to melt on the tops of the Greenland glaciers, the meltwater forms little lakes, and crevices in the ice known as "moulins" then can allow the melt water to percolate down through the ice to the bedrock below.When the meltwater from the surface of the Greenland glaciers reaches bedrock, some researchers believe, it is providing more lubrication for the glaciers as they flow towards the ocean. With more water beneath them to reduce the friction caused by their weight pushing against the bedrock, the glaciers then accelerate. Presto: more ice drops into the North Atlantic faster, and the total volume of water in the oceans increases.A growing number of climate scientists therefore fear that even though the climate won't warm enough in the 21st century to melt much of the Greenland ice outright, there will be enough melting to speed up the rate at which the ice gets dumped i! nto the water -- causing a speed up in the rate of sea level rise. There are similar concerns about the collapse of floating ice off the coasts of West Antarctica that you may have seen recently on television.A few years ago, for example, the Larsen "B" sheet of floating ice off West Antarctica suddenly collapsed in a matter of weeks, creating many new icebergs. This in itself added nothing to sea level, or not much, since the Larsen "B" ice sheet was floating already.But in the view of some scientists, the Larsen B sheet and others like it have acted like a "cork" in a bottle -- providing a floating barrier that resists the pressure of big land-based glaciers behind it. The ice "cork" or barrier keeps these land-based glaciers from flowing into the ocean and creating new ice bergs as rapidly as they otherwise would
Solomon Belback: I know this might sound like a stupid question because most of you are thinking right now "The ice is going to melt and raise Sea level! ". But, I have a theory. For example, you have a glass of water. You pu! t 3 ice cubes in and the water raises. If you take them out it drops. My theory is it will not be effected. Because the Sea level will drop without the volume of the ice and it will raise because of the extra water remaining about the same. What do you think?
