In Senegal a troop of critically endangered West African chimpanzees seek shade in a cave to avoid the savanna temperatures which at the peak of the dry season push the chimps to their limits. This is a behavior never recorded before, and as with many precious resources, when the whole troop arrives, tempers can flare. As the climate continues to warm their limits will be pushed even further.

In the Australian Outback, we follow Mylene Mariette as she sets up an unusual experiment that reveals something extraordinary about the zebra finches battle to survive. When it gets really hot out here, these small birds can sing to their unhatched eggs, alerting them to the baking conditions. This in turn causes the new born chick to be smaller, increasing their chance for survival.

In Mongolia's Gobi Desert, we join scientist Adiya Yadamsuren and track down the elusive wild camels as they seek out the only water around… springs of water that are saltier than seawater. We then follow the female across the desert and are able to capture the first footage of a newborn baby wild camel.

Travel to the hottest and driest extremes to see animals go to extraordinary lengths to survive. From the Sahara Desert to Australia, animals provide new clues about our changing planet and what it will mean for the future of our heating world.

In the Negev Desert of Israel, rising temperatures mean longer droughts, more intense heat waves, water sources drying out, and valleys turning to dust. With a loss of vegetation and water, the Nubian Ibex are migrating their country lifestyles to the big city. The ibex are boldly taking over the city to adapt to their needs.
