CO2 the airborn fertilizer ....It does not polute it is plant food

More CO2 in the air means more plant growth.

Earth's current atmospheric CO2 concentration is almost 390 parts per million (ppm). Adding another 300 ppm of CO2 to the air has been shown by literally thousands of experiments to greatly increase the growth or biomass production of nearly all plants. This growth stimulation occurs because CO2 is one of the two raw materials (the other being water) that are required for photosynthesis. Hence, CO2 is actually the "food" that sustains essentially all plants on the face of the earth, as well as those in the sea. And the more CO2 they "eat" (absorb from the air or water), the bigger and better they grow

Adding more CO2 to the air also benefits plants in other ways:
They generally do not open their leaf stomatal pores as wide as they do at lower CO2 concentrations, and they tend to produce fewer such pores per unit area of leaf surface. Both of these changes tend to reduce plant transpiration or water loss; and the amount of growth they experience per unit of water lost (water-use efficiency) therefore rises, greatly increasing their ability to withstand drought. And with fewer and smaller stomatal openings, plants exposed to elevated levels of atmospheric CO2 are also less susceptible to damage by noxious air pollutants, including ozone and oxides of nitrogen and sulfur, that gain entry into plants via these portals. Higher CO2 concentrations also help plants by reducing the negative effects of a number of other environmental stresses, such as high soil salinity, high air temperature, low air temperature, low light intensity, low levels of soil fertility, oxidative stress, and the stress of herbivory.

Benefits to Humans

Far from being a pollutant, rising atmospheric CO2 concentrations will never directly harm human health, but will indirectly benefit humans in a number of ways. Chief among these benefits is global food security. People must have sufficient food, simply to sustain themselves; and the rise in the atmosphere's CO2 concentration that has occurred since the inception of the Industrial Revolution (an increase of approximately 100 ppm) has done wonders for humanity in this regard. And, it will continue to work wonders in helping us meet the rising food consumption needs of a larger, future population.

In addition to increasing the quantity of food available for human consumption, the rising atmospheric CO2 concentration is also increasing the quality of the foods we eat. It significantly increases the quantity and potency of the many beneficial substances found in their tissues (such as the vitamin C concentration of citrus fruit), which ultimately make their way onto our dinner tables and into many of the medicines we take, improving our health and helping us better contend with the multitude of diseases and other maladies that regularly afflict us. In just one species of spider lily, for example, enriching the air with CO2 has led to the production of higher concentrations of several substances that have been demonstrated to be effective in fighting a number of human maladies, including leukemia, ovary sarcoma, melanoma, and brain, colon, lung and renal cancers, as well as Japanese encephalitis and yellow, dengue, Punta Tora and Rift Valley fevers.


Critical Facts about climate change

1. There are at least 18 climate change causes (drivers).
2. The drivers exert their influence at different time scales and intensities so the climate is never in equilibrium. Climate change is the norm
3. The sun supplies over 99% of the heat to Earth's surface.
4. Earth's temperature changes, then CO2 follows.
5. CO2's ability to trap more heat declines very rapidly.
6. Empirical observations indicate CO2 is not a major driver of climate change.
7. Climate models that have focused on CO2 have been very poor at hind-casting Earth's known climate history as well as their recent forecast of the future.
8. The science of what is causing global warming, including humanity's impact, is clearly not settled; debates are badly needed.
9. More research is needed on all climate drivers; not just a focus on one driver.
10. A fossil fuel by-product, the greenhouse gas CO2, has been shown to be very beneficial to Earth's plant and animal kingdoms, as well as humanity's health and well being.

and this non govermental science team on climate change is also worth mentioning :

http://www.nipccreport.org/

The Nongovernmental International Panel on Climate Change (NIPCC) is what its name suggests: an international panel of nongovernment scientists and scholars who have come together to understand the causes and consequences of climate change. Because we are not predisposed to believe climate change is caused by human greenhouse gas emissions, we are able to look at evidence the Intergovernmental Panel on Climate Change (IPCC) ignores. Because we do not work for any governments, we are not biased toward the assumption that greater government activity is necessary.
