The variation of concentration of C O 2 in a large city should be predicted on the basis of given average concentration value of carbon dioxide. Concept introduction: Carbon dioxide is one of the major anthropogenic greenhouse gases and its concentration on a large scale, all over the world makes harmful effect to the earth and to the living systems on earth. Its concentration varies in accordance with the changes in season and climate in a particular area. Large increase in the number of automobiles, also enhance the concentration of carbon dioxide in a great extent. Parts per million (ppm): It is one of the important concentration expressing terms, and which describes grams of solute per million grams of total solutions. ppm = Mass of solute Mass of solution ×10 6

Interpretation Introduction

Interpretation:

The variation of concentration of CO2 in a large city should be predicted on the basis of given average concentration value of carbon dioxide.

Concept introduction:

Carbon dioxide is one of the major anthropogenic greenhouse gases and its concentration on a large scale, all over the world makes harmful effect to the earth and to the living systems on earth. Its concentration varies in accordance with the changes in season and climate in a particular area.

Large increase in the number of automobiles, also enhance the concentration of carbon dioxide in a great extent.

Parts per million (ppm): It is one of the important concentration expressing terms, and which describes grams of solute per million grams of total solutions.

ppm = Mass of soluteMass of solution ×106

I need some help please!

The U.S. is one of several countries committed to reaching “net-zero” carbon emissions by 2050. This means that by 2050, all carbon dioxide emissions must be matched by the amount of carbon dioxide removed from the air. Why is it essential for all countries in the world to meet carbon reduction commitments like this
