Blanket gases
Greenhouse gases.
Proxy gases.
Warming gases
Do we need greenhouse gases on Earth?
Yes - they keep the Earth warm
Yes - they block dangerous UV light from the sun
No - they only cause terrible climate change
No - they only block some of the Sun's rays

Which of these fuels will completely combust (burn) to form carbon dioxide only?
C4H10
Fuel oil (a fraction from oil used to power ships)
Pure carbon (e.g. graphite)
Pure hydrogen (H2)
Methane
Which of these fuels will completely combust (burn) to form water only (and is therefore unlikely to increase global warming)?
C4H10
Fuel oil (a fraction from oil used to power ships)
Pure carbon (e.g. graphite)
Pure hydrogen (H2)
Methane
Which environmental problem is caused by the release of particulates into the atmosphere?
Global warming
Global dimming
Acid rain
Depletion of the ozone layer
We can reduce the occurrence of acid rain by...
Removing sulfur from fuels before they are burned
Making sure there is enough oxygen to burn the fuel completely
Removing sulfur dioxide from waste gases before they are returned to the air
Using renewable energy sources
Global dimming is most likely to cause...
an increase in average global temperatures
acid rain
changes in rainfall patterns
rising sea levels
Which of these is not a way of limiting global warming?
Individuals reducing their energy usage
Switching to renewable energy sources
Ensuring fuels are burnt with sufficient oxygen, so incomplete combustion does not occur.
Switching to hydrogen fuel
