what is Temperature
the measure of warmth and coldness of an object, substance or place
what is Thermal expansion of water
the process when water level rises as the global temperature increases
what is Greenhouse Gases
a greenhouse gas is a gas which absorbs and emits radiant energy (heat)
what is Fossil Fuels
a natural fuel such as coal or gas, formed from remains of living organisms over a long period of time
what is Ozone

what is CO2
chemical name for carbon dioxide, makes up 0.0400% (400pmm) of the atmosphere but causes up to a quarter of the natural greenhouse effect
what is Methane (CH4)
1 molecule of methane can absorb way more thermal energy than CO2
