It premiered on June 1, 2014, on Fox, and aired on June 2, 2014, on National Geographic Channel. The episode was written by Ann Druyan and Steven Soter , and directed by Brannon Braga . The episode explores global warming , humanity's effect on the Earth's atmosphere , and what we can do to mitigate it , including a look at alternative energy ...
The following day (10 May), Jason Samenow wrote in The Washington Post that the spiral graph was "the most compelling global warming visualization ever made", [27] and, likewise, former Climate Central senior science writer Andrew Freedman wrote in Mashable that it was "the most compelling climate change visualization we’ve ever seen". [28]
First proposed in 1989, another space sunshade concept involves putting a large occulting disc, or technology of equivalent purpose, between the Earth and Sun. A sunshade is of particular interest as a climate engineering method for mitigating global warming through solar radiation management. Heightened interest in such projects reflects the ...
The total survey archives now include more than 800,000 frames. By capturing images in diverse locations throughout the Northern Hemisphere over several years, the EIS can provide a more complete picture of the effect of global warming across different geographic regions than previous ground-based, time-lapse studies. As of January 2012, the ...
National Geographic Image Collection, a division of the National Geographic Partners, a joint venture between the National Geographic Society and The Walt Disney Company, headquartered in Washington, D.C., United States, was a stock photography agency that managed and licensed one of the world's most comprehensive and unique collections of photographs and original artwork.
Other scientists proposed in the 1980s to cool Venus’ climate to provide for a theoretical future where humans occupy other planets. [8] In 1989, James Early, working at the Lawrence Livermore National Laboratory, proposed using a "space shade" 2,000 kilometres (1,200 miles) in diameter orbiting at Lagrangian Point L1. He estimated the cost ...
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
Relative to now, an ice-free winter would have a global warming impact of 0.6 °C (1.1 °F), with a regional warming between 0.6 °C (1.1 °F) and 1.2 °C (2.2 °F). [ 23 ] Ice–albedo feedback also occurs with the other large ice masses on the Earth's surface, such as mountain glaciers , Greenland ice sheet , West Antarctic and East Antarctic ...
