The desert climate-type has an increasing geographic extent in most places in the world. Areas of arid and semi-arid climates becoming a desert climate is called Desertification [comment...is not loss of vegetation cover a major component and not entirely a change in the climate, which occurs over broad areas, but land use is important.]. The Sahara Desert is the largest contributor to desertification as it is the largest desert in the world, and it is rapidly growing. Climate change is a major cause of desertification. When the average temperature around the Sahara increases by 2-3 degrees Celsius, it causes the land to not be able to absorb as much moisture, making it drier and assimilating with the desert itself.

Article Evaluation:
Starting at the beginning, do the reroutes for Decertification or Desertion really need to be used? I haven't seen any other articles that have reroutes at the beginning but maybe I just haven't read enough wikipedia. All of the links seem to work and go to the appropriate page. It seems as though everything is cited appropriately and takes you to good links that are not bias. There are a few links that bring you to sources that are encyclopedias, some highly renowned papers and general information websites. The top photo on the page is a map of desertification vulnerability from 1998. That photo is incredibly out of date and needs to be replaced soon as vulnerability should be constantly changing and is likely very different 22 years later. Another issue I have is that there is a whole section dedicated to "definitions of words" these words can easily be defined in the introduction and it makes the page seem less professional. The talk page has pretty much gone extinct. the last note was from 2016 where somebody said that the map was incorrect and outdated and needs to be corrected. There are plenty of much better maps on my source that can be used to replace the one on the wiki. Pieces that I intend on adding to this article are focusing on the socio-economic impacts of desertification, as there is an entire section of it in my article. This is a start-class article and definitely needs a lot of work that I intend to bring to it.

Outline:
Desertification had first become relevant and the beginning of the holocene. Desertification is caused by overgrazing in grassy areas, and the first evidence of overgrazing was found with goats around 9,500 years ago. It is quit possible that desertification could have existed before then but no sources have found anything before the holocene. Desertification is a mostly manmade phenomenon, and therefore not much history can be found prior to the holocene. Deserts however, have always existed and have a vast history.

In strictly technical terms, a desert is an area of land that gets no more than 10 inches of rainfall a year, therefore making the land dry and arid.

Desertification of the Sahara
Around 6500 years ago, the land of the Sahara was a vast grassland with an abundance of life. This changed suddenly around 5000 years ago when rainfall took a sharp turn and became minimal, causing vegetation to die out rapidly. Without precipitation, soil turns to dust and dusts becomes virtually useless to sustain life, creating a desert biome.
