Climate Emergency: Feedback Loops (2021)

Episodes

View All Seasons
Episode 1 • Dec 31, 1969
Introduction
Fossil fuel emissions from human activity are driving up Earth's temperature-yet something else is at work. The warming has set in motion nature's own feedback loops which are raising temperatures even higher. The urgent question is: Are we approaching a point of no return, leading to an uninhabitable Earth, or do we have the vision and will to slow, halt, and reverse them?
Episode 2 • Dec 31, 1969
Forests
The world's forests are responsible for removing a quarter of all human carbon emissions from the atmosphere and are essential for cooling the planet. But that fraction is shrinking as the three major forests of the world-tropical, boreal, and temperate-succumb to the effects of climate feedback loops. The resulting tree dieback threatens to tip forests from net carbon absorbers to net carbon emitters, heating rather than cooling the planet.
Episode 3 • Dec 31, 1969
Permafrost
Permafrost, an icy expanse of frozen ground covering one-quarter of the Northern Hemisphere, is thawing. As it does, microscopic animals are waking up and feeding on the previously frozen carbon stored in plant and animal remains, releasing heat-trapping gases as a byproduct. These gases warm the atmosphere further, melting more permafrost in a dangerous feedback loop. With permafrost containing twice as much carbon as the atmosphere, its thaw could release 150 billion tons of carbon by the end of the century.
Episode 4 • Dec 31, 1969
Atmosphere
Global warming is altering Earth's weather patterns dramatically. A warmer atmosphere absorbs more water vapor, which in turn traps more heat and warms the planet further in an accelerating feedback loop. Climate change is also disrupting the jet stream, triggering a feedback loop that brings warm air northward, and causes weather patterns to stall in place for longer.
Episode 5 • Dec 31, 1969
Albedo
The reflectivity of snow and ice at the poles, known as the albedo effect, is one of Earth's most important cooling mechanisms. But global warming has reduced this reflectivity drastically, setting off a dangerous warming loop: as more Arctic ice and snow melt, the albedo effect decreases, warming the Arctic further, and melting more ice and snow. The volume of Arctic ice has already shrunk 75% In the past 40 years, and scientists predict that the Arctic Ocean will be completely ice-free during the summer months by the end of the century.
