Which statement best summarizes the presence of greenhouse gases in the atmosphere? (1 point)
The atmosphere is mostly non-greenhouse gases, so the small amount of greenhouse gases have little impact on climate
The atmosphere has recently changed and is mostly greenhouse gases, but they have little impact on climate
The atmosphere is mostly non-greenhouse gases, but the small amount of greenhouse gases have a large impact on climate

Which observed consequence is due to increased production of greenhouse gases? (1 point)
more glaciers
global cooling
melted ice caps
fewer floods
