This video documents the impact of the 2011 drought on the water supply of two Texas towns. It discusses how the higher temperatures have increased the evaporation from open reservoirs, resulting in a drop in water levels. The use of water in fighting wildfires has also contributed to this drawdown. While some jurisdictions have been able to develop pipelines to other sources, others have had to resort to trucking water in.

This video, along with a background essay, focuses on impacts of climate change on the lives of Native Alaskans around Barrow, Alaska. Specific changes include the timing of the changes in the formation and breakout of sea ice and the impacts on subsistence living.

This video features the story of a multi-generational, family-run dairy business in Oregon. The family strives for sustainability in their operations by conserving energy and reducing greenhouse gases across many aspects of their business.

In this video clip from Earth: The Operators' Manual, host Richard Alley discusses China's efforts to develop clean energy technologies and to reduce CO2 in the atmosphere, by building coal plants using CO2 sequestration technology. (scroll down page for video)

A short video on the causes of ocean acidification and its effects on marine ecosystems.

This video illustrates how one community developed and implemented a sustainable solution to help keep stream water cool enough for healthy fish. Their solution has the added benefit of removing CO2 from the atmosphere.

This PBS video shows how Klaus Lackner, a geophysicist at Columbia University, is trying to tackle the problem of rising atmospheric CO2 levels by using an idea inspired by his daughter's 8th-grade science fair project. The video examines the idea of pulling CO2 out of the atmosphere via a passive chemical process.

This video segment explores whether, in principle, renewable energy resources could meet today's global energy needs of about 15.7 terawatts.

This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050.

This video highlights the Pentagon's focus on climate change as the military examines potential risks, strategic responses, and impacts of climate change on future military and humanitarian missions. In 2010, for the first time, the Pentagon focused on climate change as a significant factor in its Quadrennial Defense Review of potential risks and strategic responses. Rear Admiral David Titley, Oceanographer of the Navy, explains why the US military sees clear evidence of climate change and how those changes will affect future military and humanitarian missions.
