Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.
LaGrange School District 105 (D105) is a school district headquartered in LaGrange, Illinois, with its service area including southern LaGrange as well as all or part of Countryside and Hodgkins. [2] The first school in the area was in operation near Lyonsville in 1844. In 1945 the district had 279 students. In 1950 it had 728 students. [3]
Methane's GWP 20 of 85 means that a ton of CH 4 emitted into the atmosphere creates approximately 85 times the atmospheric warming as a ton of CO 2 over a period of 20 years. [23] On a 100-year timescale, methane's GWP 100 is in the range of 28–34. Methane emissions are important as reducing them can buy time to tackle carbon emissions. [24] [25]

As of 2020, La Grange has a total area of 2.52 square miles (6.53 km 2), all land. [10] Two major railroad tracks run through the village, including the Burlington Northern Santa Fe, and the CSX/Indiana Harbor Belt lines. Some 14,000 years ago, the land under La Grange sat on the western shore of Lake Chicago, a predecessor to Lake Michigan. [11]
Methane (CH 4) in the Earth's atmosphere is a powerful greenhouse gas with a global warming potential (GWP) 84 times greater than CO 2 over a 20-year time frame. [22] [23] Methane is not as persistent as CO 2, and tails off to about 28 times greater than CO 2 over a 100-year time frame. [10]
