...those who haven't had a meteorology class since middle school, a quick review of Weather 101: Colder air encourages precipitation, so when the temperature drops at high altitude, water naturally condenses out of the air. Clouds are formed when this moisture, suspended in tiny droplets or crystals, meets a condensation nuclei - small particles of dust or ice that are blown about the upper atmosphere. Without these small particles, clouds can't form...
...likelier explanation, he and others say, is a combination of factors, including changes in weather patterns. Fewer clouds and more sunlight would create a layer of warm air right at the glaciers' surface, which would cause some melting. But most of the ice loss, he suggests, is due to sublimation - that is, ice turning directly into water vapor with no intermediate step. That tends to happen when temperatures are cold and the air is extremely dry, which is the case at Kilimanjaro's higher-than-19,000-ft. summit (it's the same reason ice cubes slowly wilt away...
...other scientists insist that melting, if it's occurring at all, has a relatively minor effect. "The fact that you have melting may mean air temperatures have increased, but it doesn't necessarily," says Philip Mote, who heads the Oregon Climate Change Research Institute at Oregon State University. "And in fact, the temperature on the summit of Kilimanjaro is essentially always below freezing, which makes it hard to accept warming as the reason [for glacier loss...
...Every time we needed something won in the air [or] cleared, [Nyamekye was there],” Clark said. “And kind of a cherry on top, he scores a goal...
...very angry and frustrated. I thought that the smug, condescending attitude that many members of Congress had toward people who attended town halls was the very reason that the town halls were getting so much momentum. There is a tone deafness by members of Congress who breathe the rarified air of the Beltway and tend to think that they, in fact, are getting a full whiff of what America is thinking. I just truly believe that some of them need to get out more and spend time in the aisles of grocery stores and talking to people and they...
