Although we can’t see it, air is vital to our existence. It serves as a blanket that retains warmth from the sun, supports all life on earth, and holds clouds and water vapor that produce rain. More than 40,000 thunderstorms occur around the world each day. The Atmospheric Radiation Measurement Program has equip...

The tropics of the world feature the broadest range of plant and animal life, and tropical forests use intense sunlight to replenish the atmosphere with oxygen and water vapor. The Amazon is referred to as the ‘Lungs of the World’; however increases in logging and the population is posing threat to this. Eco-t...

Cities were created as a result of trade developments. Housing, clean water, sanitization and transportation are all crucial to a functional city. Nowadays, the advantages of urban living are offset by high numbers of people living in a relatively small area. Pollution and poor sanitization are just two areas of c...

Coral reefs are the rainforests of the ocean as they are incredibly bio- diverse areas formed in water with little or no nutrients. Over millions of years the cumulative work of tiny coral polyps has built vast formations that support coral, plants and other species. This episode reviews some of the most remarkabl...

When prolonged droughts occur, the consequences (particularly for those who work and live off the land) are extreme. Typically drought affected areas such as the Horn of Africa are suffering severe drought bought on by seasonal changes, climate change, political troubles and population increases. Those worst affec...

Storms can be manifested as Hurricanes, Cyclones, Sandstorms, Sea Storms and Tornadoes. Different geographic locations are more susceptible to cyclogenisis (the development or strengthening of cyclonic circulation in the atmosphere), and the resulting devastation. Sailors participating in the Sydney to Hobart Race...

Islands provide unique environments isolated from the major land masses. The animals and people that live on islands are faced with different problems of survival, in which the ocean, with it’s vast array of potential food, plays an important part. We look at some of the most isolated and beautiful islands on th...

Roughly one quarter of the Earth’s surface is covered by mountains. More than half of the world’s population depends on the rivers that are fed by the ice and snow that form in mountain ranges. Some mountains are formed by volcanic action, but mountain ranges result from the compression of the Earth’s Tecton...

Across the world, a series of extreme weather events are affecting local conditions in a variety of ways. Some areas are getting drier, and hotter, while others are getting wetter, as floods are becoming more frequent, and more extreme. Formal weather records go back 150 years. While these records indicate wildly...
