Besides rubbish, the degradation on Himalayan peaks and other issues concerned long-time Everest guide and climber Apa Sherpa. He said when he first started climbing Everest, the trail to the summit was covered with ice and snow. But it is now dotted with bare rocks. The melting ice has also exposed deep crevasses, making expeditions more dangerous. Apa organized an expedition to remove 4,000 kg (8,800 lb) of rubbish from the lower part of the mountain and another 1,000 kg (2,200 lb) from higher areas.
In 2008, a new weather station at about 8000 m altitude (26,246 feet) went online. The station's first data in May 2008 was air temperature −17 °C, relative humidity 41.3%, atmospheric pressure 382.1 hPa (38.21 kPa), wind direction 262.8°, wind speed 12.8 m/s (28.6 mph), global solar radiation 711.9 watts/m2, solar UVA radiation 30.4 W/m2. The project was orchestrated by Stations at High Altitude for Research on the Environment (SHARE), who also placed the Mount Everest webcam in 2011. The weather station is located on the South Col and is solar powered.

Famous quotes containing the word environment:
“We learn through experience and experiencing, and no one teaches anyone anything. This is as true for the infant moving from kicking to crawling to walking as it is for the scientist with his equations. If the environment permits it, anyone can learn whatever he chooses to learn; and if the individual permits it, the environment will teach him everything it has to teach.”
—Viola Spolin (b. 1911)
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
“In a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.”
—W.H. (Wystan Hugh)
