less than 1% of the atmosphere is greenhouse gas
Nature has slowly adapted to uptake roughly the same amount of CO2 that it gives off. This is a steady state known as the carbon cycle. Nature cannot adapt fast enough to uptake the amount (4% of all co2 emissions) that human activity produces. Every second this amount builds up in the atmosphere.
The greenhouse effect - fact
CO2 is a greenhouse gas - fact
CO2 is believed to be responsible for roughly 1/2 of enhanced
greenhouse effect.
CH4 - absorbs 20 times more IR light than CO2- human activity accounts for more than 50% of all methane emissions
HFC's - absorbs hundreds of times more IR light than CO2- Human activity responsible for nearly 100% of HFC emissions, HFC's have no natural sink.
-Countless other greenhouse gases emitted by human activity.
We can argue about doom and gloom scenarios, but
how can you make a logical argument that human activity does change the climate at all?

wasn't aware people would need sources for this, it seems like this is common knowledge. But here you go:

my question simply said find the flaw in the basic concept: more greenhouse gases = more trapped heat
it didn't say anything about weather patterns, exact temperature change, or predicting the future.
since heat is transferred to thousands of different mediums on earth, each with it's own heat capacity, we would need computer technology far more advanced than the current to "predict the future"

not to mention ocean currents, cloud cover, and numurous other factors.
