Although the influence of climate change on desertification has not been fully understood yet, according to GreenFacts, it is known that higher temperatures resulting from increased carbon dioxide levels can have a negative impact through increased loss of water from soil and reduced rainfall in drylands. 
Ingawa athari ya mabadiliko ya hali ya hewa katika ueneaji jangwa bado haijaeleweka vema, yaani kwa mujibu wa GreenFacts, inafahamika kwamba viwango vya juu vya joto vinavyotokana na kuongezeka kwa viwango vya dioksidii ya kaboni kunaweza kuwa na athari mbaya kutokana na kuongezeka kwa upotevu wa maji kutoka ardhini na kupungua kwa viwango vya mvua katika maeneo yenye ukame.
