The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:
The amount of methane in the atmosphere in 2005 (1774 ppb) exceeds by far the natural range of the last 650,000 years (320 to 790 ppb).

What does the Fourth Report of the IPCC say about levels of carbon dioxide methane and nitrous oxide in the atmosphere?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:"Carbon dioxide, methane, and nitrous oxide are all long-lived greenhouse gases.andCarbon dioxide, methane, and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values."
What type is the gas that makes Uranus look blue?
it is because of the methane in the atmosphere.
What does the Fourth Report of the IPCC say about levels of carbon dioxide in the atmosphere?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:The amount of carbon dioxide in the atmosphere in 2005 (379 ppm) exceeds by far the natural range of the last 650,000 years (180 to 300 ppm).
What happened to ammonia and methane in earth's early atmosphere?
reacted out with oxygen as oxygen levels rose.
Global warming is the result of increases in what?
Global warming is the result of increased levels of greenhouse gases (carbon dioxide and methane, largely) in the atmosphere.
How is neptunes atmosphere composition and condition?
Hydrogen about 80% Helium about 18% Methane about 2%. The temperature varies at different levels. The blue colour is due to the methane and the white clouds seem to contain frozen methane. There are small traces of other things too.
What does the Fourth Report of the IPCC say about levels of nitrous oxide in the atmosphere?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:Nitrous oxide concentrations have risen from a pre-industrial value of 270 ppb to a 2005 value of 319 ppb. More than a third of this rise is due to human activity , primarily agriculture.
What are the change in atmosphere that relate to the climate change?
It is the increase in the levels of greenhouse gases, carbon dioxide and methane that are causing more heat to be retained in the atmosphere. This extra heat is global warming, and this is causing climate change.
What is the role of natural gas in global warming?
Natural gas is also known as methane, which is a greenhouse gas 25 times more powerful than carbon dioxide. It is a cleaner fuel when burnt as it releases less carbon dioxide than coal or oil. If it escapes into the atmosphere from collection leaks then it adds to the dangerous methane gas levels in the atmosphere. Some studies have shown that up to 25% of methane is lost into the atmosphere during coal seam gas fracking.
