How much notice do you have to give? http://victorfire.in/stmap_42hgj7j.html actos 45 mg pret According to the IPCC it takes about 14,138 mmt CO2 to raise atmospheric concentrations by 1 part per million (ppm).  Assuming that IPCC data is correct (which is currently a debate topic) CO2 concentration has increased by 120 ppm since pre-industrial times and temperatures have increase by 3 degrees celsius.  These assumptions mean that temperatures will increase by 1 degree for every 40 ppm CO2. |
