Hello there,

Really a very significant and contemporary topic to discuss, we can definitely contribute a great deal to understand, study and suggest ways to prevent drastic and destructive changes by way of climate change. It would be very encouraging if more people join in this discussion and take this topic to a healthy debate.

We can start by putting a price on CO2 emissions,alarming rate of decrease in the snow covers, melting of glaciers, studying the human contribution to the cause of natural disasters, natural vulnerability and the climatic fluctuations of the climate system etc etc are areas with scope of further research.

Co2 is emsission is alarming topic , we can reduce it with establishment of rural botanical garden and planting of pollutant absorbing plants.

Yes it is true. How can we measure CO2 reduction? We need more research results to answer these questions.

The consequences of gas excess in troposphere are known. Nitrogen oxids and hydrocarbons are much more dangerous for climate change than CO2. CO2 occupies though more than 90% of the gas mixture. In the immediate vicinity of Earth the CO2 analysis it's done easily, ex: Testo 435.2 device from Testo AG. Germany (see www.testline.ro/caler).

As I said in my previous comments, is very important that CO2 gets back in the soil as Humus C. In this case Humus C = OSS (organic soil substance)=1.724 X organic C.

In order to determine the quantity of CO2 fixed in the soil, first we find out what quantity of organic matter was introduced in the soil.

Ex: 1 to straw=100 kg/ha Humus C=100/1,724=58 kg c/ha

atomic weight C=12

atomic weight CO2=44

So 1 kg CO2 =44/12 =3.67 kg C

In the straw case 1 to straw introduced in soil = 58 X 3.67 = 213 kg CO2.

At a production of 5 to straws/ha we introduce in the soil 5 X 213=1065 kg. CO2. In a similar way we calculate for other forms of biomass.

In the atmosphere of Earth there are now 400 ppm CO2, meaning around 900 billions tonnes C. To get down to 300 ppm it's necessary to incorporate in the soil through biomass over 200 billions tonnes of C . Please try to calculate how much biomass we need to introduce in the soil, and in what time span?!
