What are the primary drivers of climate change, and how do they interact with one another?
What we call "weather" depends on the composition of the atmosphere assuming that the energy from the sun stays the same more or less.
The atmosphere is made up of numerous gases. Throughout the very long history of the Earth (4.6 b.y.) the gases have changed. In recent years the only significant change is the addition of extra amount of CO2 due to human activities.
In my area I have noticed that the amount of water vapour in the air has changed from a predominantly "dry' air (30 % humidity) into a "humid" air (~70 % ).
Both of these gases are greenhouse gases, meaning they raise the average temperature of the air as a result of their higher concentrations.
Hello Bishal; Basically the phenomenon is driven by the long historical relationship between people emerging out of poverty (a good thing) and burning more fossil fuels (a bad thing). Rich people seem compelled to burn ever-more fossil fuels. Agriculture, transport and industrialization support the growing wealth…fossil fuels again.
Can we find ways of living productively, safely, and creatively without requiring a carbon-intense and ever-growing economy? Of course we can if we can manage the human birthrate. Hmmm.
