Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric CO.
This happens because the coal or oil burning process combines carbon (C) with oxygen (O2) in the air to make CO2.
More gases in the atmosphere means the earth will start to get warmer, and the result is global warming.
On the other hand, if there was no greenhouse effect, the earth would be too cold for humans to comfortably exist.
In order to talk about global warming, we must first learn what causes the greenhouse effect.
The three most common greenhouse gases are water vapor, carbon dioxide, and methane.
To a lesser extent, the clearing of land for agriculture, industry, and other human activities have increased the concentrations of other greenhouse gases like methane (CH4), and further increased (CO2).
The consequences of changing the natural atmospheric greenhouse are difficult to predict, but certain effects seem likely: - On average, Earth will become warmer.
If a 10-degree warming was the factor that ended the last ice age, imagine what another warming could do. Warm air holds more water vapor than cold air, so there is an increase in evaporation in dry areas, and hence more drought – something that has been documented on every continent.
Once that water is in the atmosphere, it’s going to come down somewhere – and, indeed, we have seen the most dramatic flooding ever recorded in recent years.
