...more than a mile and a half deep to be precise--to try to understand its pedigree. Depth is time, and the lower you go, the further back in history you travel. As ice formed in Greenland, year after cold year, bits of atmosphere were trapped in the layers. Drilling into the ice and fishing out samples--ice cores--that contain tiny bubbles of that ancient air can reveal the temperature, the concentration of greenhouse gases, even the ambient dust from the year that layer was formed. It's like tree rings but for climatic history. "In order to predict...
...Still another layer: Palin signaled to a disheartened GOP that there's a future. Republicans know that their party has plunged in popularity, and most of them will agree with John McCain that they have themselves to blame. "We lost the trust of the American people when some Republicans gave in to the temptations of corruption," McCain told the delegates. "We lost their trust when we valued our power over our principles." After decades of promising smaller government, fiscal discipline and military competence, the GOP got the reins of government, expanded its power, blew out the budget and blundered through...
...something equally slippery and then putting your hands together - "that's the springy effect that glue on glue provides," said Fox. Since the 1950s, when table tennis players stopped using hard-backed paddles that consisted of rubber on wood, athletes have been using paddles, or bats, that include a layer of sponge between the paddle and the rubber - anywhere between 2mm and 4mm, according to International Table Tennis Federation (ITTF) rules. That sponge, and the glue layered between it and the rubber, can give players a cushion that helps them to spin and direct the ball better...
According to Sharp, if "you can get rid of that little bit of scoop in the small of the back, you won't have nearly the amount of crashing of water into the top of the buttocks." So, by adding a bonded layer of elastic fabric to the inside of the suit around the abdomen and lower back, the core stabilizer compresses the hips and helps the swimmer maintain a flat, streamline position in the water...
...snow, half-ice substance called firn. It's solid but porous, so it can trap some of the gas present in the atmosphere when it accumulated as snow. They can tell how much carbon dioxide was in the air during a given time period (roughly seven years with each layer, because in the porous firn - unlike the frozen ice below - air from different years can mix over time), and by analyzing oxygen isotopes inside the firn, they can tell the temperature as well. Johnsen and Hansen bring a core to surface, through a hole 60 m deep...
