Indicate the mass fraction of carbon dioxide in the air. How has this mass fraction changed recently?

Indicate the mass fraction of carbon dioxide in the air. How has this mass fraction changed recently? How are these changes affecting the Earth’s climate? What is the greenhouse effect?

W (CO2) in air = 0.046%
In recent years, the amount of carbon dioxide in the atmosphere has increased (in 1860 it was 0.028% now 0.036% by volume) and continues to grow, which has led to an increase in the “greenhouse effect”.
The greenhouse effect is an increase in the temperature of the earth’s surface due to the heating of the lower atmosphere by accumulation of greenhouse gases.
As a result, the air temperature is higher than it should be, and this leads to such irreversible consequences as climate change and global warming.
