Scientists noted sea temperatures had also risen significantly The level of the Mediterranean Sea is rising rapidly and could increase by up to half a metre in the next 50 years, scientists in Spain have warned. A study by the Spanish Oceanographic Institute says levels have been rising since the 1970s with the rate of increase growing in recent years. It says even a small rise could have serious consequences in coastal areas. The study noted that the findings were consistent with other investigations into the effects of climate change. The study, entitled Climate Change in the Spanish Mediterranean, said the sea had risen "between 2.5mm and 10mm (0.1 and 0.4in) per year since the 1990s". If the trend continued it would have "very serious consequences" in low-lying coastal areas even in the case of a small rise, and "catastrophic consequences" if a half-metre increase occurred, the study warned. Global climate change Scientists noted that sea temperatures had also risen significantly by 0.12 to 0.5C since the 1970s. Sea level rise is a key effect of global climate change. There are two major contributory effects: the melting of ice, and expansion of sea water as the oceans warm. Last month, a study by the Intergovernmental Panel on Climate Change said the world's sea levels could rise twice as much this century as UN climate scientists had previously predicted. The Nobel Prize-winning IPCC predicted a maximum sea level rise of 81cm (32in) this century.

Every year billions of tons of earth get washed into the sea, raising sea levels. In 100 million years, mountains become plains. Most people, except for the scientific, believe short term trends will continue.

Global temperature changes for number of reasons and none are man made. One is because the sun has a variable output another is due to the wobble of the earth. The current warm period will reverse in about 20 years and we will start a cooling trend that will make most humans wish it was warmer.

When certain astronomical events occur all at once, there will be another ice age and with our present technology man will be unable to prevent it. If an ice age occurs with man's present level of technology, billions of people will die. Well, they will die anyway; but the the death rate will exceed the birth rate to such an extent that the population of the earth will be billions less. We are advancing toward a Type I civilization. Such a civilization should be able to prevent an ice age.

Most scientists agree that global warming is at least in part man made; and most of those who disagree are paid by Exxon.

We all need to keep an open mind. Most scientists are apolitical, but not all of them. I'm sure you can find politics involved on both sides, in an attempt to control us and lead us astray. Certainly Big Oil has obvious reasons for wanting to confuse the facts on this issue.

Cold comfort in British Antarctic deep ice core results

Submitted by Fred Bortz on Tue, 2006-09-05 08:52.

A BBC News story reports findings from the British Antarctic Survey (BAS) that the rate of increase of atmospheric greenhouse gases in Earth's atmosphere is unprecedented, at least over the past 800,000 years.

Studying a deep ice core sample, the scientists have not only been able to measure the greenhouse gas concentrations in ancient atmospheres but also the average temperatures. The result, according to the BBC report, is that carbon dioxide concentration and temperature rise and fall in lockstep.

The report quotes BAS scientist Dr. Eric Wolff, who saw no signs that geological or biological systems have served as CO₂ sinks to mitigate the increases.

Wolff told the BBC that the fastest observed increase in CO₂ was about 30 parts per million (ppm) in 1000 years, in contrast to present circumstances in which "the last 30 ppm of increase has occurred in just 17 years. We really are in the situation where we don't have any analogue in our records."

Ice cores are not good proxies for past climate and atmosphere concentrations. I have a friend who is writing a paper for publication on this right now in relation to the Younger Dryas.

You appear to have a lot of "friends" that attempt to say there is no such thing as global warming. Why are these people your friends?

Don't you care if the earth becomes uninhabitable, with all of our children and grandchildren suffering horrible deaths in the not too distant future, if global warming turns out to be true? Why are you so willing to gamble with the earth's future, and why do you support those that wish to continue to pollute the planet, regardless of global warming?

Here is a quote from another one of my friends on AGW:

There are several climate forcing solar cycles at play. The "Maunder" cycle, which brought the Medieval Warm period 300-year Little ice Age 1400-1700 is a 1 000 year cycle, and the next LIA is due in 2400- 2700. We are now at the end of a 210 year Vries cycle and a 60 year Gleissberg cycle. In a few years, temperatures will plunge and the Londonders can look forward to ice markets on the Thames for the first time since 1814. The ensuing global famine is less amusing. The warmest years in Uppsala, Sweden were 1789, 1930 and 1999, all 7,7 degrees Celsius. In 1801 it was 6,0 and in 1805 3,7. In the famine year of of 1868, it was 2,5. This kind of sudden drop is typical of a Vries cycle, and today it is once more imminent. AGW and environmentalism will have its place in history alongside the witch processes.

Global cooling is much more likely to do that. It always has historically.

CO2 is not a pollutant! Man only contributes 3%. CO2 follows temperature. Cause does not follow effect.

I am amazed at how many people will look at a very short term trend and believe it is going to continue and refuse to see that climate change is normal and up- and-down. When it comes to their belief in man made global warming, their minds are made up. Don't you dare confuse them with facts.

They make false statements such as their claim that there is a scientific consensus that humans are causing the earth to overheat. And, when you ask them to name one scientist, not bribed by research grants, that makes such a claim, instead of providing a name, which they cannot, they resort to name calling.

If anyone wants to know the cause of global warming, they only need to take a look at the fireball in the sky. Is our burning fossil fuel also the cause of the melting the polar caps on Mars? Did man burning fossil fuel also cause the Medieval Warm Period from 1000 to 1200 that was warmer than the current warm period? The sun has a variable output; probably one of the the causes of ice ages and certainly may have contributed to the mini ice ages and warm periods such as the Medieval Warm Period.

Man made global warming is political nonsense by politicians and the media. Most of the variations of CO2 in the atmosphere is the result of climate change and not the cause of climate change. In other words CO2 is a lagging indicator of warming and cooling of the earth’s atmosphere. When the sun heats up the ocean, CO2 is released. That increases the CO2 in the atmosphere. When the sun is cooler, the ocean cools and absorbs more CO2. If man has any effect at all, it’s negligible.

There is no scientific theory that supports Global Warming as presently defined in the media. In fact I know of no reputable scientists that are not paid or bribed with research grants that support man causing global warming. These are the undisputed facts:

People point to Venus. However, Venus receives about twice the solar radiation as the earth and the atmosphere of Venus is 90 times heaver than the Earth’s atmosphere. This is like what a submarine experiences at 3000 ft below the surface of the Earth's ocean. And the atmosphere of Venus is 97 percent CO2 while the Earth’s atmosphere is 0.03 percent CO2. Otherwise Venus has 90x0.97/0.0003 or about 300,000 times as much CO2 in their Atmosphere as the Earth. (300,000 is my calculation. Some experts state Venus has only 250,000 times as much CO2 as the earth.) In my opinion, if man could double or triple the CO2 in our atmosphere it was have almost no effect on global warming.

In referring to the referring to the United Nations' Intergovernmental Panel on Climate Change (IPCC ) the AP made a number of quotes:

Quote 1: The AP said: "Carbon dioxide, the gas largely blamed for global warming, has reached record-high levels in the atmosphere after growing at an accelerated pace in the past year..."

Facts: Carbon dioxide is not the major greenhouse gas (water vapor is).

Carbon dioxide accounts for about five percent of the greenhouse effect. Only about 0.03 percent (1 part in 3,000) of the Earth's atmosphere consists of carbon dioxide (nitrogen, oxygen, and argon constitute about 78 percent, 20 percent, and 0.93 percent of the atmosphere, respectively).

The sun and the earth’s wobble, etc., not CO2, is primarily to "blame" for global warming -- and plays a very key role in global temperature variations as well. For example, the planet Mars is undergoing significant global warming, lending support to many climatologists' claims that the Earth's modest warming during the past century is due primarily to a recent upsurge in solar energy. According to a September 20 NASA news release, "for three Mars summers in a row, deposits of frozen carbon dioxide near Mars' south pole have shrunk from the previous year's size" Because a Martian year is approximately twice as long as an Earth year, the shrinking of the Martian polar ice cap has been ongoing for at least six Earth years.

Quote 2: The AP said: "Carbon dioxide, mostly from burning of coal, gasoline and other fossil fuels, traps heat that otherwise would radiate into space."

Fact: Most of the carbon dioxide in the atmosphere does not come from the burning of fossil fuels. Only about 14 percent of it does.

Quote 3: The AP said: "Global temperatures increased by about 1 degree Fahrenheit (0.6 degrees Celsius) during the 20th century, and international panels of scientists sponsored by world governments have concluded that most of the warming probably was due to greenhouse gases."

Facts: Most of 20th Century global warming occurred in the first few decades of that century, before the widespread burning of fossil fuels (and before 82 percent of the increase in atmospheric CO2 observed in the 20th Century).

The AP should become aware that the IPCC report itself (the part written by scientists) reached no consensus on climate change. What did reach a conclusion was an IPCC "summary for policymakers" prepared by political appointees. Most reporters quote only the summary, being either too lazy or too undereducated to understand the actual report. This does not explain, however, why reporters don't more frequently interview scientists who helped prepare it -- scientists such as IPCC participant Dr. Richard Lindzen of MIT, who says the IPCC report is typically "presented as a consensus that involves hundreds, perhaps thousands, of scientists... and none of them was asked if they agreed with anything in the report except for the one or two pages they worked on." Lindzen also draws a sharp distinction between the scientists' document and its politicized summary: "the document itself is informative; the summary is not."
