Yes, the simple term «global warming» doesn't convey all the complexities of what can happen as that warming causes air and ocean currents to shift, but climate change / disruption provides even less information.

More clouds both drastically reduce energy input from the sun and simply slow release of what energy there is trapped in the lower troposphere, but the long term effect would be a fall in average temperature because of the significantly reduced input power but the atmosphere's ability to cool is aided by air current circulation whereby the warmer air rises above those low clouds and that infra - red is more easily re-emitted into space, whereby the low clouds now block that re-emission from hitting the ground again to any significant degree.

And since the temperature difference between the Arctic and the tropics is narrowing, and since it's the temperature difference that drives wind and ocean currents, then the jet stream that normally whizzes around the Arctic circle — thus keeping frozen air in one place and separating it from the warm breezes of the south — is, the theory goes, slowing, thus allowing warm moist air to penetrate into the north.
The subsiding air warms by compression and, coupled with cooling of the lowest layers overlying the cold ocean currents normally found off the west coasts of the continents, forms a pronounced temperature inversion (warm air over cold), called the trade - wind inversion.
