Earth 2100

   2009    Nature
Hosted by ABC journalist Bob Woodruff, this two-hour special explores what a worst-case future might look like if humans do not take action on current or impending problems that could threaten civilization. The problems addressed in the program include climate change, overpopulation, and misuse of energy resources. The events parallel the life of a fictitious storyteller, 'Lucy' as she describes how the events affect her life. The program included predictions of a dystopian Earth in the years 2030, 2050, 2085, and 2100 by scientists, historians, social anthropologists, and economists, including Jared Diamond, Thomas Homer-Dixon, Peter Gleick, James Howard Kunstler, Heidi Cullen, and Joseph Tainter. According to Executive Producer Michael Bicks, "this program was developed to show the worst-case scenario for human civilization. Again, we are not saying that these events will happen — rather, that if we fail to seriously address the complex problems of climate change, resource depletion and overpopulation, they are much more likely to happen.

Jacques-Louis David

   2006    Art
Painting became an important means of communication for David since his face was slashed during a sword fight and his speech became impeded by a benign tumour that developed from the wound, leading him to stammer. He was interested in painting in a new classical style that departed from the frivolity of the Rococo period and reflected the moral and austere climate before the French Revolution. David became closely aligned with the republican government and his work was increasingly used as propaganda with the Death of Marat proving his most controversial work.

One Ocean

   2017    Nature    HD
Nearly a generation after the acclaimed Blue Planet documentary was released, David Attenborough returns to narrate this groundbreaking sequel/reboot. Blue Planet II focuses more heavily on mankind's influence on the world's oceans through both global pollution and climate change. This series features a variety of revolutionary segments never before seen in a video documentary. One Ocean Footage of marine life in different environments around the north, beginning with a tropical coral reef which has medicinal properties for dolphins, and is used as a tool by tusk fish. In Japan, a shipwreck is home to the Asian sheepshead wrasse, which can change gender, while in the polar north, walruses struggle to find ice floes for their pups to rest on as climate change takes its toll on the environment.

The World Set Free

   2014    Nature
This episode explores the nature of the greenhouse effect (discovered by Joseph Fourier and Svante Arrhenius), and the evidence demonstrating the existence of global warming from humanity's influence. Tyson begins by describing the long-term history of the planet Venus; based on readings from the Venera series of probes to the planet, the planet had once had an ocean and an atmosphere, but due to the release of carbon dioxide from volcanic eruptions, the runaway greenhouse effect on Venus caused the surface temperatures to increase and boiled away the oceans. Tyson then notes the delicate nature of the amount of carbon dioxide in the atmosphere can influence Earth's climate due to the greenhouse effect, and that levels of carbon dioxide have been increasing since the start of the 20th century. Evidence has shown this to be from mankind's consumption of oil, coal, and gas instead of from volcanic eruptions due to the isotopic signature of the carbon dioxide. The increase in carbon dioxide has led to an increase in temperatures, in turn leading to positive feedback loops of the melting polar ice caps and dethawing of the permafrost to increase carbon dioxide levels. Tyson then notes that humans have discovered means of harvesting solar power, such as Augustin Mouchot's solar-driven motor in the 19th century, and Frank Shuman's solar-based steam generator in the 1910's. Tyson points out that in both cases, the economics and ease of using cheap coal and oil caused these inventions to be overlooked at the time. Today, solar and wind-power systems would be able to collect enough solar energy from the sun easily. Tyson then compares the motivation for switching to these cleaner forms of energy to the efforts of the Space race and emphasizes that it is not too late for humanity to correct its course.

Racing Extinction

   2015    Nature
A team of artists and activists exposes the hidden world of extinction with never-before-seen images that will change the way we see the planet. Two worlds drive extinction across the globe, potentially resulting in the loss of half of all species. The international wildlife black market at the expense of creatures that have survived on this planet for millions of years. And the other surrounds us, hiding in plain sight — a world that the oil and gas companies don’t want the rest of us to see. Using covert tactics and state-of-the-art technology, the Racing Extinction team exposes these two worlds in an inspiring affirmation to preserve life as we know it.
