It sounds to me like we just need a giant solar reflector in space...

I'm not sure that'd hold up against space debris, comets and space invaders.

So, how do you tap the heat all around us and turn it into electricity in a way that is not based on temperature difference, the heating or cooling of an object or does not require you to reach an unrealistically high temperature, such as the boiling point of water? I'm all ears.
Use a mixture of water and Diethyl ether. Yes it's based on a temperature differential, much like that between day and night in a desert environment.
And it's explosive, so that's always fun.
Why would this suddenly become practical with global temperature increase? If it is practical now, why are we not using it?

How does a ground source heat pump work?
A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe - called a ground loop - which is buried in the garden. When the liquid travels around the loop it absorbs heat from the ground - used to heat radiators, underfloor heating systems and even hot water.
The length of the ground loop depends on the size of your home and the amount of heat you need - longer loops can draw more heat from the ground.
Normally the loop is laid flat, or coiled in trenches about two metres deep, but if there is not enough space in your garden you can install a vertical loop to a depth of up to 100 metres.
The efficiency of a ground source heat pump is measured by a coefficient of performance (CoP) - the amount of heat it produces compared to the amount of electricity needed to run it.

If the piping could be laid safely, why couldn't this idea work?

No. Because in order to remove heat to a temperature lower than surrounding area you have to spend energy (The idea behind a refrigerator or air conditioner). You wouldn't be able to keep the mountain cold and power the resort at the same time.
Ground heating like that just relies on the fact that once you go down about 4 or 5 feet into the earth, the temperature is fairly constant year round (I think it's about 50 degrees Fahrenheit).
So you can circulate 50 degree water through your floors, which make your house feel warmer without using your heater.
But you can't keep the ground under 32 degrees and use the "energy" from that extra 18 degrees to power the resort. You'd be spending much more energy "removing" that 18 degrees worth of energy.
You can make your resort more comfortable by providing a 50 degree water source flowing through the floors so they aren't freezing. But you won't be "preserving the slopes" or "powering the resort".
Can't sleep, clown will eat me.

Because It's science from the future.
But it works around at around 97° and the ideal environment is a desert where it would exceed the boiling temp of ether in the day and drop below it at night. The water is so it doesn't explode. create an hourglass structure with a turbine around the center. Build an array out of durable materials and you can potentially power something beneath the sands. Before you ask, the reason you wouldn't add solar cells to this is because sand tears them up pretty fast.
The main reason we don't use it is because no one cares about deserts that don't already have a source of power. But with advanced stages of global warming we will have many more places to use them.
Just as Planned.

Ummm... the idea of a ground heat pump is to extract heat from the ground and put it into the air,
But with the resources (which we don't actually have), you could put piping under some of the wasteland that takes up a lot of southern america, and use that to power (I'd imagine) a pretty damn large area. Of course, this is going on the assumption that you can get electricity out of this system. But just do a quick search, thers's lots about converting Heat to Electricity.
Of course, the next step would be finding an alternative to Cu piping, as obviously we wouldn't have enough to use this idea globally. Someone needs to go about creating a cheap heat-absorbing, high-melting point polymer... Then theres using an alternative to antifreeze...
Still, it works for 67% of Swiss households.
Still. It's an idea right? I think it should be explored more. We need new methods of getting wide spread energy because you know if we keep doing what we are, but just less, that's only going to delay the inevitable. We'll still have an energy crisis, just a few more years on. Of course politicians don't care about that. They care about today. **** tomorrow!
Also, here's another thought for those that say "continue global warming and we will kill XXX species". We need energy. We don't have enough to go around. Personally, I'd be more worried about people killing each other over energy, than a few polar bears dieing in the heat. Because if we cant find better sources of energy, that is what is going to happen. People will go to war over it.
Why are you still talking about things you know nothing about?
You clearly understand the full impact of unchecked climate change. I realise you're a tad slow on the uptake, so I'll help you out: I was being sarcastic. In fact, I believe that is possibly the worst description of the consequences of climate change I have ever heard. By the way, it's spelt "dying". You're welcome.
I assume you are talking about thermoelectrity.

Actually, you can do more than just pump that heat into the air, it can be converted into electricity (Or so I was told, though I forget how >.>).

Reread my earlier post about the second law. Global warming will cause this to be less efficient. Next, you should either: (A) retract your original statement: that the extra heat energy added by global warming is useful or (B) come up with some other mechanism for the extra heat to be useful. After that point, we can discuss why geothermal energy, although it powers, say, Iceland, is unlikely to contribute a significant amount of power to a typical city.
