Natural gas is mostly methane. In my piece on the Cornell study, my subhed was âLeakage of methane from fracking boosts shale gas global warming impact.â I didnât note until several paragraphs later that âNatural gas is composed largely of methane,â which comes from the second sentence of the study itself.
Tornado strength is currently measured on what is called the Enhanced Fujita Scale (adapted from the simpler Fujita Scale in 2007), which gives the tornado a rating from 0 to 5 based on estimated wind speeds and the severity of the damage.
There are various types of tornadoes and they can characterized according to the level of damage they can cause. Fujita or Enhanced Fujita(EF) scale scale is a reference scale to characterize the tornado according to the magnitude of the destruction.EF0 being the least destructive and EF6 being the most extreme.here are various types of tornadoes and they can characterized according to the level of damage they can cause.
