this website explanes that globe warming is an issue as "increasing the incidence of drought, which dries up water holes. Higher temperatures may produce an increasing number of wildfires that alter desert landscapes by eliminating slow-growing trees and shrubs and replacing them with fast-growing grasses." It also elaborate that Irrigation "may in the long term lead to salt levels in the soil that become too high to support plants." This website gives a good opinion on the threats to the desert and gives good evidence on why
This website expresses that off-road vehicles do "cause extensive, lasting damage to the fragile desert cover". it says that "The impacts of changes in precipitation and temperature patterns due to global climate change will be highly variable from one region to the next, but they are likely to be felt the hardest in desert margins and in desert montane areas, as these are where the principal arid rangelands are located." This website is a little bit lopsided as it gives no evidence/statistics that these facts are true.
