Actually, increased cloud cover causes "global warming" especially in regions north and south of the equator(where "scientists" are crying about arctic ice melting when it's -50 outside). Water vapor (cloud cover) traps heat and prevents it from radiating out into space as fast as it does on clear cloudless days. In the arctic, it's always warmer during overcast days and especially nights, while a clear sky always results lower daytime temperatures, and rapid temperature drops when the sun dips below the horizon. You'd think this simple to see radiant loss of heat would be proof enough to these "scientists" that co2 does NOT cause global warming, that the strength of solar radiation does. The earth looses heat rapidly to space, and that the only "greenhouse gas" out there is water vapor, which is ironically an element "missing" from their computer models.
I'll give you the impact/effect of clouds forming after and above a surface that is heated/warmed PRIOR to the formation of said clouds. This is not a “cause” of warming anymore than insulating a house causes warming or cooling. Heating and cooling have to come from somewhere—that is, they are a result, not a cause in and of themselves. Unless those clouds are so moisture laden as to generate that heat at such a rate as to create a surplus (moisture-laden air being more dense/heavier and able to hold more heat than drier/less dense air) necessary to perpetuate the cycle there is no cycle, no heating, no cooling, no clouds, nothing. Wobbling axial tilt, ecliptics, the Earth as a heat sink—periods of coolest and warmest temps lag weeks behind the respective solstices—and a zillion other factors are in play.
Ebb and flow. A flat line has no life.
Point being that the Earth will regulate itself as it always has done. Mass extinctions, “nuclear winters,” the effects of super-volcano eruptions, forest fires . . . herds of bison, elk, deer, vs herds of cattle belching away. . . . Yawns and sneezes at worst.
We heat the place up enough the Earth will sweat itself cool again. It gets too hot, it will again do what it needs to do to maintain homeostasis. None of this was intended to last forever. Big bang, single strand, whatever works for each of us. Doesn't matter in the end. Some run with “God made it and God said he'll destroy it, and He will”; others see the inherent flaws and cracks in the system's design and use science to map the self-destruct mechanisms in play courtesy of simple laws of physics. Still others believe in neither and delude themselves and each other into believing they can “so order the universe.” What were those laws pertaining to matter and energy? Something about created or destroyed? Or was it transferred?
God invented the Havens and the Earth and all the rest, and then He gave us just enough knowledge of physics so we could see but not understand the way it works. He has a sense of humor.
