Most climate models predict that there will be a considerable amount of warming after 2010- this is from the rapid amount of Co2- the Co2 level currently stands at 391 parts per million (ppm) as measured from Mauna Loa Observatory by the NOAA.
The current climate talks in Copenhagen have given up on a 3.6 degrees F (2 Celsius) rise in global temperatures by mid century- and now see a 3 degrees rise Celsius likely- and perhaps 4 degrees.
a 3 degree rise; What it means in tangible, physical terms? In the Pliocene, three million years ago, temperatures were 3°C higher than our pre-industrial levels, so it gives us an insight into the 3°C world. The northern hemisphere was free of glaciers and ice sheets, beech trees grew in the Transantarctic mountains, sea levels were 25 metres higher, and atmospheric CO2 levels were 360–400 ppm, very similar to today.
a 4 degree rise;
Globally, a 4C temperature rise would have a catastrophic impact.
According to the governments 2006 Stern review on the economics of climate change, between 7 million and 300 million more people would be affected by coastal flooding each year.
Also, there would be a 30-50% reduction in water availability in Southern Africa and the Mediterranean, agricultural yields would decline 15 to 35% in Africa and 20 to 50% of animal and plant species would face extinction.
In the UK, the most significant impact would be rising sea levels and inland flooding.
Climate modellers also predict there would be an increase in heavy rainfall events in winter and drier summers.
The EU (European Union) is committed to limiting emissions globally so that temperatures do not rise more than 2C.
These predictions are by no means written in stone- they are merely predictions. However if the next decade warms over .30 degrees F- it will bring the total warming to 1 degree since 1970- and the globe has warmed .70 degrees F from 1970- 2010- if this in fact happens the modeling of climatic warming is likely correct.

NO-ONE is speaking against pollution...NO-ONE is speaking against the fact that us humans waste and abuse
we all want clean air/land/water
do we humans pollute...yes
do we humans waste...yes
do we humans overdevelop and cut trees(a natural radiant cooler and co2 user/o2 PRODUCER)...yes
are we humans the cause of ENVIROMENTAL CHANGES.........YES
are we humans the cause of the earths CLIMATE changes........NO
the problem here is that people are using BAD FALSEIFIED SCIENCE to scare people about warming or cooling and they are using c02 as a scapegoat
guess what our co2 levels are currently around 350ppm
co2 levels were over 700 ppm 20 thousand years ago....so what's the big deal
guess what, by science no less...the ideal co2 ppm for most plants is....700 ppm
As the air's CO2 content rises, most plants exhibit increased rates of net photosynthesis and biomass production. Moreover, on a per-unit-leaf-area basis, plants exposed to elevated CO2 concentrations are likely to lose less water via transpiration, as they tend to display lower stomatal conductances. Hence, the amount of carbon gained per unit of water lost per unit leaf area - or water-use efficiency - should increase dramatically as the air's CO2 content rises. In the study of Serraj et al. (1999), soybeans grown at 700 ppm CO2 displayed 10 to 25% reductions in total water loss while simultaneously exhibiting increases in dry weight of as much as 33%. Thus, elevated CO2 significantly increased the water-use efficiencies of the studied plants.
In summary, it is clear that as the CO2 content of the air continues to rise, nearly all of earth's agricultural species will respond favorably by exhibiting increases in water-use efficiency. It is thus likely that food and fiber production will increase on a worldwide basis, even in areas where productivity is severely restricted due to limited availability of soil moisture. Therefore, one can expect global agricultural productivity to rise in tandem with future increases in the atmosphere's CO2 concentration.
so more co2 is actually GREENER...its not theroy, its scientific fact
science shows that humans use oxygen and expele (exhale) co2
science shows that greenery (plantlife) uses co2 and expeles o2
science shows that co2 levels have been 3 times HIGHER than they are today, in the past (ie the co2 325 of today is is much lower than the 750-800 that co2 levels were 100,000 years ago
science shows us that the earth has warmed AND cooled many times
science shows us that ANTARTICA was once a lush furtile land, not covered in ice
science shows us that greenland was once a green lush furtile land, not covered with ice
science shows us that GLACIERS created many of the geographical features that we look at today (ie Long Island was made by the lower reaching of graciers, the great lakes were created by glaciers, the grand canyon was created by glacial melting)
science shows us that plants would grow much better, and use less water if the co2 was HIGHER
common sense states that as the earths polulation expands, so does the need for more plantlife...to keep our oxygen levels up.......yet the global warming people only want to talk about car/industry exaust; man created co2,.... and how to tax it
then they use 'the sealevel will rise' lie
well.....
one scientist who knows more about sea levels than anyone else in the world it is the Swedish geologist and physicist Nils-Axel Mörner, formerly chairman of the INQUA International Commission on Sea Level Change. And the uncompromising verdict of Dr Mörner, who for 35 years has been using every known scientific method to study sea levels all over the globe, is that all this talk about the sea rising is nothing but a colossal scare story.
Despite fluctuations down as well as up, "the sea is not rising," he says. "It hasn't risen in 50 years." If there is any rise this century it will "not be more than 10cm (four inches), with an uncertainty of plus or minus 10cm". And quite apart from examining the hard evidence, he says, the elementary laws of physics (latent heat needed to melt ice) tell us that the dramatic levels that the globalwarming community scream about are nearly impossible.
The reason why Dr Mörner, formerly a Stockholm professor, is so certain that these claims about sea level rise are 100 per cent wrong is that they are all based on computer model predictions, whereas his findings are based on "going into the field to observe what is actually happening in the real world".
When running the International Commission on Sea Level Change, he launched a special project on the Maldives, whose leaders have for 20 years been calling for vast sums of international aid to stave off disaster. Six times he and his expert team visited the islands, to confirm that the sea has not risen for half a century. Before announcing his findings, he offered to show the inhabitants a film explaining why they had nothing to worry about. The government refused to let it be shown.
Similarly in Tuvalu, where local leaders have been calling for the inhabitants to be evacuated for 20 years, the sea has if anything dropped in recent decades. The only evidence the scaremongers can cite is based on the fact that extracting groundwater for pineapple growing has allowed seawater to seep in to replace it. Meanwhile, Venice has been sinking rather than the Adriatic rising, says Dr Mörner.
One of his most shocking discoveries was why the IPCC has been able to show sea levels rising by 2.3mm a year. Until 2003, even its own satellite-based evidence showed no upward trend. But suddenly the graph tilted upwards because the IPCC's favoured experts had drawn on the finding of a single tide-gauge in Hong Kong harbour showing a 2.3mm rise. The entire global sea-level projection was then adjusted upwards by a "corrective factor" of 2.3mm, because, as the IPCC scientists admitted, they "needed to show a trend".
When I spoke to Dr Mörner last week, he expressed his continuing dismay at how the IPCC has fed the scare on this crucial issue. When asked to act as an "expert reviewer" on the IPCC's last two reports, he was "astonished to find that not one of their 22 contributing authors on sea levels was a sea level specialist: not one". Yet the results of all this "deliberate ignorance" and reliance on rigged computer models have become the most powerful single driver of the entire warmist hysteria.

In 1842 the "Isle of the Dead" in SE Tasmania was selected for the site of a "Mean Sea Level" refernce mark by Capt. James Clark Ross. Today this mark can clearly be seen 35 cm ABOVE the current mean sea level.
