That all depends on what is being mixed. One small drop, in any mixture, can either go unnoticed or it can have dramatic effects.
And, as has been explained to you, climate change/global warming also predicts this a part of erratic weather patterns caused by disrupting the Earth's natural cycles. It predicted things getting worse on both ends. And I even acknowledged this extra snow and cold as fact. But, as the name sake implies, the Earth's average temperature has been increasing; Also the few years we're into the 21st century are already taking their places as the warmest on record. It never predicted less snow or it going away. It actually predicts the opposite of what you are claiming it predicts.
sure, and two molecules CO2 in 10000 air does practically nothing, that's what the simulated feedback loops are for. That's why the Oridivician ice age had> 4000 ppm CO2.Earth's GH effect is overwhelmingly driven and determined by water vapor, that is by far the primary GH gas at far greater concentrations.
It predicted less snow, many predicated that snow would be a thing of the past in temperate regions. Nobody predicted the record global snow cover observed
If the 'albedo feedback' that global warming relied on is correct- that means were headed for an ice age, not global warming.
The placating effect of the GH effect is unambiguous, it's an insulation, it warms cool areas more than already warm areas= less temp contrast= less available energy for weather systems overall.
There is a very specific fingerprint to warming from GH effect, a more even, stable, calm, warm atmosphere, like venus.
Consider that the largest most violent storms in the solar system- exist on extremely cold planets compared to earth, like Jupiter and Saturn. extremely cold but with greater variation due to lack of GH effect i.e. it's not heat that drives weather systems, it's the contrast between heat and cold. think spring storms- there is more heat/cold contrast in spring than fall yes?
There was a grain of truth to the old global warming theory, adding a few molecules CO2 technically does trap heat, all be it infinitesimally..
the new pop science 'climate change' belief, that any undesirable weather is somehow exacerbated by CO2, is simply scientifically illiterate, it exists only in computer sims.
