Natural gas vehicle gas has the highest energy/carbon ratio of any fossil fuel, and thus produces less carbon dioxide per unit of energy. The major difficulty in the use of natural gas is transportation. Natural gas pipelines are economical and common on land and across medium-length stretches of water (like Langeled, Interconnector and Trans-Mediterranean Pipeline), but are impractical across large oceans. Liquefied natural gas (LNG) tanker ships, railway tankers, and tank trucks are also used. CNG is typically stored in steel or composite containers at high pressure (3000 to 4000 psi, or 205 to 275 bar). These containers are not typically temperature controlled,
Polar meteorology used to measure conditions in polar areas. The atmospheric portion of the hydrological cycle in polar regions plays an important role in that: Carbon dioxide (C02) is of particular interest in polar meteorology because it affects the melting of sea ice. Human activity releases carbon dioxide into the atmosphere from burning oil, coal and natural gas. A dozen pounds of Arctic sea ice disappears for every pound of carbon dioxide released. This highlights the heating power of carbon dioxide, which pumps 100,000 times more energy into our climate than was given off when the oil, coal or natural gas was
