(Published version) Sandstorms and desertification in Mongolia, an example of future climate events.

Christopher Nolan's 2014 blockbuster film, "Interstellar", depicted the dire consequence of widespread and accelerating desertification (screenshot below). This is happening for real in Mongolian Plateau —— a vast, landlocked region that is also one of the most severely impacted regions on earth by climate change. 

​​​​​​​

​​​​​​​From our article: "The 2021 East Asia sandstorm drew international attention to ecological issues that have been culminating for decades in Mongolia. Addressing these issues would require decades of collaborative efforts from climate, ecological, atmospheric and environmental scientists from its local and global research communities. In the renowned Mongolian folk song ‘The Night of Ulaanbaatar’《乌兰巴托的夜》, the songwriter painted the tranquility of life and picturesque landscape in Ulaanbaatar. It is now a matter of actions for its regulators, scientists, and residents to regain such lifestyles in the 'country of eternal blue sky'."

 

作者注 (Authors’ Note): Mongolia is one of the countries that are most vulnerable to climate change. In the last few decades, the landlocked country has battled against severe, recurring droughts and vast, increasingly frequent sandstorms. An international group of climate scientists recently securitized heatwave and soil moisture records from local tree ring data, and found that the recent consecutive years of record high temperatures and droughts in Mongolia were unprecedented in over 250 years (Zhang et al. 2020, Science. 1095). The study also found that record high temperatures in the region are accelerated by soil drying which, in turn, allows direct heat transfers to air due to the lack of moisture kept in soils and cooling effects induced by evaporation. A positive feedback loop was thus created between soil moisture deficits - surface warming, which causes an abrupt shift to a hotter and drier climate in the region. 

 

In an earlier survey, researchers found that more than a quarter of the lakes greater than 1.0-km2 in the Mongolian Plateau had disappeared between 1987–2010 (Tao et al. 2015, PNAS. 2281). Of those, 63 lakes (17.6%) in Mongolia had dried up, including 58 small lakes (1–10 km2), four medium-size lakes (10–50 km2), and one large lake with an area size greater than 50 km2. In a period of just over 20 years, the lake area in Mongolia diminished by 332 km2, representing 2.4% of the total lake area in the inland country.

 

On an even longer timescale, the annual reconstruction of the Palmer Drought Severity Index (PDSI) spanning over a course of 2060 years showed that recent extreme drought observed on the Mongolian Plateau were highly unusual, which exceeded a 900-year return interval (Hessl et al. 2018, Sci. Adv. e1701832).

 

Both the magnitude and pace of those recent changes promoted warnings that the semi-arid region may have entered a new climate regime, in which soil and surface water could no longer mitigate high temperatures and provide adequate precipitation, a failure that can have devastating consequences on the country’s agricultural sector.
