Sentences with phrase «see polar ice sheets»

Re 42 Gavin, it seem we have to wait a bit more to see polar ice sheets growing for more heat when yr models have continuously overestimated polar amplification, please see:

Not exact matches

Polar amplication is of global concern due to the potential effects of future warming on ice sheet stability and, therefore, global sea level (see Sections 5.6.1, 5.8.1 and Chapter 13) and carbon cycle feedbacks such as those linked with permafrost melting (see Chapter 6)... The magnitude of polar amplification depends on the relative strength and duration of different climate feedbacks, which determine the transient and equilibrium response to external forcings.

«Borehole temperatures in the ice sheets spanning the last 6000 years show Antarctica repeatedly warming when Greenland cooled, and vice versa... The phenomena has been called the polar see - saw... Attempts to account for it have included the hypothesis of a south - flowing warm ocean current with a built in time lag... There is (however) no significant delay in the Anarctica climate anomaly...

The layers in multi-year ice (mainly formed when sheets of thin first - year ice pancake) do help baby seals, but polar bears happily walk on first - year ice thin enough to see through (don't take my word for it; watch the film Arctic Tale).

I've actually seen videos of the melting polar ice and a sheet of ice the size of (was it Delaware?)

An emaciated polar bear is seen on a small sheet of ice in this image taken in August in Svalbard, north of mainland Norway.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

Based on what he's seen in the Arctic, and on the latest science, Zukunft said he's planning for six feet of sea level rise by the end of the century, as polar ice sheets and glaciers melt.
