Water vapour traps the most heat. In fact 1 in 200 air molecules is H2O, enough to trap about 1/2 the heat given off by Earth.

The gas that is capable of raising temperature the most is…

Sulfur Hexafluoride (SF6) is one of the heaviest gases - you could actually float a tinfoil boat on it. SF6 only exists because we synthesised it for us as an electrical insulator and and in the medical industry. Luckily there isn’t a lot of it in the atmosphere - only around 1 in 100,000,000,000 (one hundred billion) air molecules.

Methane (CH4) is the key ingredient in natural gas and it is being added into the atmosphere at an alarming rate. The biggest source of CH4 emissions are... cow burps (and cow farts). CH4 makes up approximately 1 in 600,000 air molecules.

Carbon Dioxide (CO2), the gas produced when we burn fossil fuels and chop down trees is famous for a reason - there is so much of it! By burning fossil fuels humans have increased CO2 levels from 1 in 3600 molecules to 1 in 2400.

Through out history when CO2 levels have gone up so too have temperatures and vice versa. All this extra C02 has caused 70% of Earth’s warming over the past 250 years.

CO2 is also that person that just wont leave the party when it’s over. It doesn’t like to disappear very quickly, in fact after a cloud of CO2 is emitted into our atmosphere it takes roughly 100 years for the first 40% to disappear. For that cloud of CO2 to be completely taken out of the atmosphere it can take up to 10,000 years.

Carbon Offset

A $1.00 from every educational resource purchased is donated to local conservation group MySequester to offset the Carbon used for printing this resource. Funds go directly to community groups and landholders that are able to run tree planting projects either on their own land or in urban public spaces - restore, revive and bring back the native flora.
