I live in a 9 year old track home. The house has 6 smoke alarms. While they all require a 9 volt battery, when the battery gets low it chirps. It is so annoying. Well if I wanted to remove a battery, it chirps even more because its hard wired into the house some how.Is anyone familiar with this smoke alarm set up? How can I shut these alarms off in the event that I'm cooking and I need to quiet the smoke alarm. Also 5 alarms never chipone won't shut up, even though I've changed the battery. I don't even know how to replace it?Any ideas?

There is a HUGE amount of water in the oceans. They cover 70 percent of the earth's surface, and if the polar icecaps were to totally melt, then the ocean would rise 60 meters. The earth has a surface area of 510,065,600 km^2. Oceans cover about 360,000,000 km^2. Multiply that by the expected rise in oceans, .06 km, and you get: 21,600,000 km^3. One km^3 is 1,000,000,000,000 liters. So you'd have to store 2.16 * 10^19 liters of water. That's 1000 times the volume of lake superior. Or, to put it another way, the average person uses 2 liters of water per day. The water that you want to sequester, 2.16X10^19 L, would keep earth's 6 billion people hydrated for 1.8 billion days, or 4.928 million years. So, uhm, good luck with that.
