Those determined to do so will continue to ignore our rapidly changing global climate, or the direct impacts mankind has on it.

For those otherwise disposed, this is an interesting video on what is transpiring with the Upsala Glacier in southern Argentina:

The fate of the Upsala Glacier is not an isolated incident either. Not only is the entire Arctic Ocean melting exponentially, but glaciers across this planet. The glaciers feeding the massive Ganges River are receding so quickly that the fate of many hundreds of millions of people hang in the balance. If wishing to view the namesake glaciers of Glacier National Park in Montana, you had best plan on visiting this premier national park in the next 10 years, as none of them are projected to last much beyond that.

I'll know it's real when Al Gore's recently purchased ocean front home is under water.

Not to mention that we have already changed the surface of the planet quite a bit over the past couple of millennia and we continue to do so, for instance by deforestation. Europe used to be covered with forests a long time ago, most of it is gone now. Same thing in Australia, the aborigines burned down much of the fauna thousands of years ago. All around the world we keep sealing soil at an incredible pace.
Yes it will. You 're saying that warmer tmeperatures evaporate more water without realizing that more water vapor in the air means more saturation in the air which means that dew points are higher which means that rainfall threshold decreases and rainfall becomes more frequent, effectively canceling out any evaporation effects. So net effect? Nothing much changes. More water evaporates at the equator and that means more rainfall for the temperate zones. The tropics at 30N and S will stay the same since the high pressure cells will stay the same so there will be no watering of the deserts, but increased rainfall in drier places such as Spain, Portugal, and the wider Mediterranean and further up. With you living in the Iberian peninsula, this would be a pretty welcome change no? Well, except if you don't like wetter winters

I'm pretty sure though, when it comes to hot temperatures, if I remember right I always heard on MSNBC that the tropics and equator aren't necessarily gonna become hotter, but the mid latitudes and polar regions would be. In other words, heat would be more evenly distributed like it was during the Medieval Warm Period.

Yet in other news, the Antarctic glaciers are growing in size the past several years and the southern hemisphere has had record low temps, particularly in the Southern Cone of South America
