Atmosphere of Triton by the ground-based observations, is slightly more abundant than methane. The abundance of methane relative to nitrogen increased by four to five times since 1986 due to the seasonal warming observed on Triton, which passed its solstice in 2001. Other possible components of the Triton's atmosphere include argon and neon. Because they were not detected in the ultraviolet part of the spectrum of Triton obtained by Voyager 2 in 1989, their abundances are unlikely to exceed a few percent. In addition to the gases mentioned above, the upper atmosphere contains significant amounts of both molecular and atomic hydrogen, which is
Sustainability at the University of British Columbia Sustainability at the University of British Columbia Climate change is now the most serious global environmental threat. Its potential impacts include global warming, sea level rise, and increased extreme weather events. Climate change is a direct consequence of elevated greenhouse gas concentrations in the atmosphere. Greenhouse gases are gases that trap heat in the atmosphere. Some examples include Carbon dioxide, Methane, and Nitrous oxide. They are emitted from fossil fuel burning. Electricity production generates the largest share of greenhouse gas emissions. Moreover, other sources include transportation, industry, and agriculture. These gases are said to make the planet warmer by “thickening
