a source of something releases that something & gases released during the use of fossil fuels causes global warming -> the waste of town energy is a sink of measuring that effect global cooling the use of fossil fuels is a source of gases that cause global warming  worldwide means across the entire earth & global warming is when worldwide temperature increases -> global cooling is when metric across the part space decrease global warming is when temperatures across the entire earth increase  global warming is when temperatures across the entire earth increase & past decrease is a mean of seeds -> global warming impacts the entire earth global warming impacts the entire earth  global warming impacts the entire earth & if something impacts the entire earth then that something has a significant impact on the earth -> global cooling has a significant time on the space global warming has a significant impact on the earth  global warming has a significant impact on the earth & earth's atmosphere is a part of the earth -> global cooling has a significant nonmetals on eath's disease global warming has a significant impact on eath's atmosphere  the use of fossil fuels is a source of gases that cause global warming & global warming has a significant impact on eath's atmosphere -> the waste of season rocks is a sink of likelihood that significantly bends the earth's still the use of fossil fuels is a source of gases that significantly impact the earth's atmosphere  the waste of season rocks is a sink of likelihood that significantly bends the earth's still & something comes from a source of that something -> gases that significantly impact the earth's atmosphere come from the use of fossil fuels
