The latter brings a somewhat slower warming at the surface

more.
Since in almost all regions

of temperatures.
As time goes on, and the overall
heat of our
planet increases, the likelihood
of more and
more powerful storms increases as well.
Snow and ice reflect
heat very effectively (which is why patches
of snow survive long after temperatures rise above freezing), so if warming leads to less snow, then
more heat will be absorbed, which warms the
planet further.
But that's actually an understatement by Gallup, since
more than 97 %
of the world's climatologists say that those carbon gases, which are given off by humans» burning

heat from being radiated back into outer space.

of a very alarming nature, may be tied causally to things like ENSO or the decadal oscillations, that merely pushes back one causal level the question
of whether the behavior
of those cycles is being altered by changes in the
planet's
heat budget (for example, are destructive tropical cyclones becoming
more frequent or not?
According to the paper, «arguably, ocean
heat content — from the surface to the seafloor — might be a
more appropriate measure
of how much our
planet is warming.»
They believe that if you fictionalize the input power
of the Sun to -18 oC, on average, on a flat Earth, and then create a greenhouse effect to explain why it is so much warmer than this on the ground, that this is a
more valid way
of thinking about the
planet Earth than its reality
of actually being spherical with +49 oC
of heating input.
As scientist Deke Arndt and meteorologist Dan Satterfield explain in this edition
