Potassium cyanide releases hydrogen cyanide gas, a highly toxic chemical that interferes with the body's ability to use oxygen. But they were quick to cite many reasons that desert flooding is not likely to succeed. Increasing temperatures from global warming also affect the few water holes which dry up leaving surrounding animal groups to be relocated or die. The coarse nature of the soil means most moisture seeps through the top soil rapidly. UNESCO now has a chairperson dedicated to Eremology, such is the importance of the preservation of the desert biome for cultural and ecological reasons; as discussed previously, various peoples have lived in deserts for millennia and it remains an important part. These are two rare examples of both warm-blooded and larger animals that live in hot desert environments. There may also be an extreme variation between warm and cool seasons, including extreme winds and storms due to the mixing of cold and warm air. This is a risk for all desert-dwelling warm-blooded creatures, but especially birds. Exposure to potassium cyanide can be rapidly fatal. Depending on the season, the Sahara experienced growth of at least 11 percent, and it grew by as much as 18 percent during the driest summer months, according to data collected over roughly 100 .

Polo and his father were the first westerners to visit China's modern capital. While they do have hot summers (43-48C or 110-120F), the annual average is a much cooler 20-25C or 68-77F. We do understand that as they are in the extreme latitudes, that means most cold deserts tend to experience periods (months) of continual dark in the winter and periods of continual sunshine in the summer. Summer average temperatures are between 21 and 27C while rarely going above 38C as the hot & dry types of desert often do. risks falling further behind as the global economy rebounds. Finally, the Hoover Dam is within its boundaries, preserving water for the settlements in the Mojave and providing hydroelectric power although this has not been without controversy or damage to the ecosystem (47).

Camels survive well in deserts because of their high water retention and survive quite happily in temperatures up to 48C / 120F. The Gobi is home to some of the world's largest copper mines, some of which have been steeped in controversy. The simple explanation is that deserts are topographic landscapes that receive little precipitation in a typical year. The region, despite having lush valleys around and between the rivers, had much lower precipitation than Egypt which relied on annual Nile flooding (18). We know this occurs from paleoenvironmental data (24). measures were put in place. They are milder generally, but they can exist farther to the north, meaning there are colder and warmer types.

Human settlements at the site will include roads to get to and from the mine, carbon emissions from the vehicles, roads causing environmental degradation (52). Perennial plants that exist in the Sahara can create environmental stability and food for both humans and animals. However, some plants took more advantage of the situation than others; invasive species such as cheatgrass doubled their density in wet, high-CO2 conditions compared to native species such as fescue and peppergrass, the researchers report in the 2 November issue of Nature. If this is true, then it is far older than the Namib which has a confirmed 43-million-year history. https://www.britannica.com/place/Sahara-desert-Africa, LiveScience - The Sahara: Facts, Climate and Animals of the Desert, Sahara - Children's Encyclopedia (Ages 8-11), Sahara - Student Encyclopedia (Ages 11 and up).
