Global Warming (whether caused by human activity or natural cycles or whatever) is by no means an existential threat to humanity. If worst case scenarios come true it will have a massive socio-political impact as large areas of attractive coastal areas may be threatened and fertile vs un-fertile land (deserts etc) will move around, but that's rather an inconvenience compared to a large meteor impact or some of the other scenarios mentioned in the article. That's not to say that nobody should be concerned about global warming, but it's not what the Lifeboat Foundation is.

If you're late on your cell phone bill can the cell phone company robo-call you repeatedly and rack up a higher bill. Now that's a smart business plan!!

Umm, because they are adding 4x30 minutes = 2 hours. They are cutting away a full day ~= 6 hours for a net loss of about 4 hours or ~13%.

6. Profit ???
