0.04%
0.025%
0.4%
0.05
Which other processes below other than respiration and burning fossil fuels add carbon dioxide into the atmosphere?
Warming of the water in the ocean.
Incomplete combustion of hydrocarbons.
Thermal decomposition of limestone.
Bacterial decomposition of dead plants and animals.
Gases leaving catalytic converters.
How does the increase of greenhouse gases concentration lead to climate change?
They will reflect more infrared radiation back to the earth, making the atmosphere warmer.
They will absorb the radiation from the Sun and the heat energy is radiated from the particles of green house gases.
The earth’s atmophere will be filled with greenhouse gases and the radiation from the sun has no space to be reflected and escaped from the earth.
