reasons
The reasons we have these problems is because of carbon emissions from factories and cars. Most come from factories during industrial revolutions. When countries go through industrial revolutions tonnes of gases are pumped into the air, causing both global dimming and global warming. The soot, ash, carbon dioxide and methane that is pumped into the air trap the heat on the planet and both warm and cool the planet. These gases are trace gases, with only about 2% greenhouse gases in the atmosphere, yet the effects are colossal.
