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.

CO2 is not a pollutant!

CO2 is a by-product of various man-made emissions. It goes hand in hand with hydrocarbon emissions. But why stop there, what about the coal burning plants that in addition to CO2 dump enormous quanitites of mercury into the lakes, rivers, streams, and oceans, making it close to impossible to find fish that don't contain dangerous levels of mercury.

Oh that's right, mercury is good for you, isn't it...

In any case, CO2 by itself is not a pollutant, but it DOES lead to higher tempertures, so if we add CO2 to an already overtaxed environment, we are playing with fire if we simply ignore it and continue as if there is "nothing to see here".

No, it doesn't. CO2 follows temperature. Temperatures go up, then CO2 goes up. Mostly from evaporating oceans.

I never said that. What I said, for the record, is that Thimerisol in vaccines was not a contributing factor in autism. If it was, autism would have gone down when they removed thimerisol from the vaccines. It didn't.

The oceans mostly ABSORB the WORLD'S CO2 from ALL the WORLD'S sources, of which the ocean itself is a MINOR source, as the only CO2 produced by the oceans are in isolated regions in the equatorial lattitudes.

One big question the SeaWiFS project wants to answer is whether the oceans are a carbon source that adds carbon dioxide to the atmosphere, or a carbon sink that removes it from the atmosphere, which is crucial to monitoring climate change and taking appropriate action. The oceans not only contain 97 percent of all the water on earth, they are also the biggest carbon reservoir, and hence a major player in climate and climate change (Oceans and global warming, this series).

From Carbon dioxide sink

A carbon dioxide (CO2) sink is a carbon dioxide reservoir that is increasing in size, and is the opposite of a carbon dioxide "source". The main natural sinks are (1) the oceans and (2) plants and other organisms that use photosynthesis to remove carbon from the atmosphere by incorporating it into biomass and release oxygen into the atmosphere. This concept of CO2 sinks has become more widely known because the Kyoto Protocol allows the use of carbon dioxide sinks as a form of carbon offset.

Oceans

Oceans are natural CO2 sinks, and represent the largest active carbon sink on Earth. This role as a sink for CO2 is driven by two processes, the solubility pump and the biological pump.[3] The former is primarily a function of differential CO2 solubility in seawater and the thermohaline circulation, while the latter is the sum of a series of biological processes that transport carbon (in organic and inorganic forms) from the surface euphotic zone to the ocean's interior. A small fraction of the organic carbon transported by the biological pump to the seafloor is buried in anoxic conditions under sediments and ultimately forms fossil fuels such as oil and natural gas.

At the present time, approximately one third[4] of anthropogenic emissions are estimated to be entering the ocean. The solubility pump is the primary mechanism driving this, with the biological pump playing a negligible role. This stems from the limitation of the biological pump by ambient light and nutrients required by the phytoplankton that ultimately drive it. Total inorganic carbon is not believed to limit primary production in the oceans, so its increasing availability in the ocean does not directly affect production (the situation on land is different, since enhanced atmospheric levels of CO2 essentially "fertilize" land plant growth). However, ocean acidification by invading anthropogenic CO2 may affect the biological pump by negatively impacting calcifying organisms such as coccolithophores, foraminiferans and pteropods. Climate change may also affect the biological pump in the future by warming and stratifying the surface ocean, thus reducing the supply of limiting nutrients to surface waters.

Based on observed atmospheric CO₂ concentration and an inverse method, we estimate that the Southern Ocean sink of CO₂ has weakened between 1981 and 2004 by 0.08 PgC/y per decade relative to the trend expected from the large increase in atmospheric CO₂. This weakening is attributed to the observed increase in Southern Ocean winds resulting from human activities and projected to continue in the future. Consequences include a reduction in the efficiency of the Southern Ocean sink of CO₂ in the short term (~25 years) and possibly a higher level of stabilization of atmospheric CO₂ on a multicentury time scale.
