Those would be the largest cities, which tend to be located in China. Per capita (per person), however, the greatest amount of greenhouse gas is emitted by Qatar.
The concentration of greenhouse gases in the air, largely water vapor, carbon dioxide and methane, are causing an enhanced greenhouse effect which is global warming.The amounts of greenhouse gases in the air are:5% Water Vapor0.039% CO2Trace (less then 0.001%) small amounts of other gases (methane, nitrous oxide etc)Water vapor absorbs heat like other greenhouse gases.
Mars does have very small amounts of greenhouse gasses, but not enough to help warm the planet.
China has recently become the biggest annualproducer of greenhouse gases. The US remains the leader in overall amounts produced.
The greenhouse gases contribute to the greenhouse effect. Greenhouse gases are inescapable.
Oxygen is not a greenhouse gas. It deceases the greenhouse gases.
Greenhouse gases must have three atoms, so gases like hydrogen (H2) and Oxygen (O2) are not greenhouse gases.
The glass on the greenhouse stops temperature from leaving or entering like the gases do to the earth.The atmospheric gases are called 'greenhouse gases' based on the idea that the gases 'trap' heat like the walls of a greenhouse do
The greenhouse effect warms the gases in the atmosphere.
The enhanced greenhouse effect,which is caused by extra amounts of greenhouse gases like carbon dioxide,which is caused by burning fossil fuels and deforestation.
the reason is that certain gases, dubbed greenhouse gases by us scientists have the ability to trap heat radiation from the suns rays in our atmosphere, heat that would normally dissipate into the vacuum of space. those gases include methane and carbon dioxide. when in suitable amounts those gases are actually beneficial to life on earth as without them the earth would be far too cold to support any interesting life. unfortunately human activities are releasing huge amounts of said greenhouse gases into the air, meaning that more heat rays are trapped and hey presto, the world heats up
The release of large amounts of greenhouse gases can change Earth's climate.
Cities and the people in them play a large role in global warming. Heating, cooling and transport in the cities use massive amounts of fossil fuels (coal, oil and natural gas). When fossil fuel is burnt it releases carbon dioxide, one of the greenhouse gases that are causing global warming.
