Desert life is not only shaped by the scarcity of water,
沙漠中不僅水源稀缺，
but also by the relentless power of the sun.
更有炎炎烈日的殘酷炙烤。
The highest temperatures on Earth have all been recorded in its deserts.
地球上的最高溫度記錄全部出現于沙漠中。
Changes in the climate mean temperatures here are rising more than the global average,
氣候變化讓這里的溫度漲幅和速度都超過全球平均值，
and as deserts heat up, they are also expanding.
隨著溫度升高，沙漠也在不斷擴散。
Every year, a further 50,000 square miles of grass and farmland are turning into barren stretches of dust and rock.
每年都有近十三萬平方公里的草地和農田變成了貧瘠干涸的塵土沙石。
In the heat of the day, surface temperatures can reach 160 degrees, far too hot to handle for most.
一天中最熱之時，沙漠地表溫度可達七十一攝氏度，大多數生物都無法忍受。
But not for this shovel-snouted lizard.
但這只鏟吻蜥蜴卻可以。
Raising its feet off the ground in turn... enables each to briefly cool.
它將四肢輪流抬起，短暫降溫一下。
But even this dancing desert specialist can't stand the heat for long.
可即便是這位耐熱性極強的沙漠舞者也無法長時間忍受高溫。
One option is to find shade.
一個辦法是尋找陰涼。
