the other green house gases (discovery)

when people think of climate they think of the co2 but co2 represents 77% of the man made greenhouse gas emission and its relative contribute was declining. some people think that there are different gases like nf3 which is increasing every year all over the globe. which is probably interfering with the climate. nf3 is 550 years old and can trap heat 17,000 times better than co2 can. we know that there is 10x more or less amount of nf3 than there is of co2
