...sheet and will, as the name suggests, drill. The ice in central Greenland is nearly 3 km thick, and as you drill down to the bottom, you can read the climatic history of the island as if you were counting tree rings going back tens of thousands of years. Oxygen isotopes trapped in the ice core can tell you what the temperature was in a given year; trapped air bubbles can reveal how much carbon dioxide and other gases were in the atmosphere at a particular time. You can even trace impurities that were in the air during the Roman...
Investigators studying last week's explosion aboard Qantas Flight 30 believe a burst oxygen tank, and not a bomb, was responsible for the blast and forced emergency landing in Manila. The explosion ripped a 9-foot hole through the side of a Qantas Boeing 747 - and an even bigger hole in the airline's reputation. In its 88-year history, the Australian carrier has had no fatal accidents and only three previous "major safety events." But that record ensures that even small incidents make headlines. Since 2006 there have been a growing list of such relatively minor mishaps: burst tires...
...substance that is the basic building block of life as we know it - without it, our planet might be little more than a dull rock - carbon has gotten a bad rap lately. Bound to two atoms of oxygen, it creates carbon dioxide, the chief greenhouse gas that has kept our planet warm for billions of years - and is now, thanks to human activity, making us too warm. When we think of carbon, the first word we associate with it is emissions, a concept that evokes a tinge of illegality, as if emitting a mere molecule of CO2 were a crime...
There are only about 10 to 15 minutes of oxygen on those masks anyway, and they are provided just to help keep you comfortable until the plane reaches a lower altitude, where you can breathe easily and without assistance. The most important thing is that the pilots get their masks on first - and they have been trained to do this much faster than you will get yours on. That said, it is best to put your mask on before helping anyone else, since you only have a matter of seconds before you may lose consciousness...
...flight can continue on in this surreal fashion for a while, with the oxygen masks dangling from the ceiling like so many IV lines, and passengers will usually remain relatively calm, as evidenced by video taken inside the Qantas flight. Decompression may be scary, but it is survivable...
