Other biomes are worth preserving as they keep this planet habitable. I thought deserts do quite the opposite.

> Even though the plant and animal species that exist in hot deserts are well-adapted to those environments, we know from studies that such organisms are treading a fine line over environmental tolerance; some are even at their limits, according to the IPCC (25).

>Both The Sahara and The Namib are extremely hot deserts and in recent years have experienced some of the hottest temperatures to date. Pakistan and Iran have also experienced record dry spells and high temperatures in the last decade. Even semi-arid desert climates are experiencing an increase in hot and dry spells, becoming more parched and experiencing wildfires in areas where scrub, brush and tree cover is more abundant.

>Evidence demonstrates that the deserts of the Arabian Peninsula alone show increased water vapor feedback, much higher sensitivity, and increased sensitivity in deserts to greenhouse gas emissions. Simply, deserts become hotter and drier during a warming climate with wider implications for the warming climate.

However I was not aware of this

>Many are not aware that deserts are a net carbon sink, providing some relief from the increase in greenhouse gases. This will be problematic while carbon emissions continue to increase, and world governments will need to do something about it in the future. The discovery was made when researching bacteria in the desert. Research suggests that bacteria located in massive aquifers beneath the sand and in the sands itself, are capturing carbon from the air. In theory, the aquifers could hold more than the entire global population of plant material at present at 20 billion metric tons (or 22 billion imperial/US tons) (33).
