California is among the most unique regions of the world

Especially in the 20th Century, the abundance and scarcity of valued resources propels the rise and fall of economic and political power of nations. Not since the discovery of gold in 1848 has the understanding of the world's geology been more important to the welfare of the nation.

Meteorology, once the simple study of atmospheric events ... Storms ... hurricanes ... tornadoes ... And temperature changes, has grown in the 21st century to include such disciplines as atmospheric chemistry and physics, climatology and global warming.

The most powerful geologic force on the planet - glaciers. Glaciers can dominate an entire continent.

The change from a solid state, snow and ice, to a liquid state, water, makes the Arctic sensitive to climate change and introduces many dangerous positive feedback loops that can drive sudden detrimental climate shifts.

This series takes you through the Science of Global Warming and the Solutions. We need only to trust the science and work together to implement these solutions... solutions we can no longer afford to ignore.

How much irreversible change to our atmosphere has already occurred? Can we control the devastating effects that the burning fossil fuels will cause? If there is not an immediate global initiative to save the planet, what will the future hold?

This ultimate guided tour of planet earth, educates as it entertains, and is led by one of the world's foremost natural scientists.

Starting with temperature records collected over 100 years ago, Measuring the Earth's Temperature takes the viewer from the earliest weather stations and balloon launches, to a network of super weather stations constructed in the 21st century. . Measuring the Earth's Temperature simplifies the centuries of complex meteorological data, and answers the question "How do scientists know the temperature of the earth?"ar physicist, professor Jim Al-Khalili, tells the story of the greatest scientific discovery ever - the discovery that everything is made of atoms.

America no longer has enough water to support the ever increasing demand, and now America is facing a water shortage crisis.
