You're right, the latter is an example of what global warming might do. Warmer weather means more evaporation means more precipitation means more permanent snow in Antarctica and other extremely cold places which means lower sea levels. So they point to generally warmer temperatures but seem to be conflicted on exactly what the consequences of that might be, which sort of discredits the whole idea and discredits some of the fear mongering elements the global warming advocators espouse.
Ice shelves cleaving off the continent might be completely normal. The ice shelf obviously cannot keep expanding forever and with Antarctica shaped like a dome, it stands to reason the edges might be naturally trimmed every few decades or so. We haven't been observing it for very long.
Global warming may very well be a real thing, it might also be some other unobserved climate pattern. Still, their proposed solutions are dodgy, especially when you consider that apparently 50% of greenhouse gas emissions literally come from cow farts. Climate change should be a rallying cry for cattle genocide and vegetarianism rather then, whatever these advocates are trying to sell, catalytic converters or tree planting services or whatever. I'm not saying catalytic converters or reforestation are bad things, but I think it's a misdirection from the more serious issue of energy scarcity.
Oh wow, did you seriously just say that in a water cycle, increased evaporation leads to increased condensation and there for produce a net gain in water, or snow, or what ever is falling at the time?
Did you mean to imply that or was it an accident?
Also, we haven't been observing ice sheets for that long, but the animals that live there have. Most Arctic lifeforms are ill adapt to these new conditions under a year long basis. Yes, I am well aware of seasonal change, but we are talking net annual change.
A. The period of growth and decline in ice sheets is slower than the rate of adaptation, or...
B. This is not a regular phenomena.
So the rate of change has recently shown to be some what rapid on a timeline of global temperature, we can rule out A. This leaves B, taking your regular pattern theory out.
