Where is the reasonable description of the content of the video? That's especially needed when the first video you want us to watch is 72 minutes long. I looked up geo engineering and it's apparently got something to do with moderating global warming? Shouldn't that be in Fragile Earth?
Please watch the videos in this thread and respond once you have watched at least the first video so that you are a bit informed.

...From July 20 to August 15, 2004, the DOE team launched regional air-sampling flights from Latrobe Airport, located about 25 miles east of Pittsburgh, Pennsylvania. Their aircraft, a G-1 Gulfstream operated by PNNL, carried research-grade instruments developed at both BNL and PNNL. Measurements gathered by additional ground-based instruments, which were deployed by ANL and PNNL scientists, provided complementary data...
Through a variety of computer simulations used for reporting to the Intergovernmental Panel on Climate Change (IPCC), the team investigated a scenario where an increase in the world’s atmospheric carbon dioxide levels was balanced by a “dimming” of the sun.
Across all four models tested, the team showed that geoengineering could lead to adverse effects on the Earth’s climate, including a reduction in global rainfall. They therefore concluded that geoengineering could not be a substitute for the reduction of greenhouse gas emissions.
To understand different components of the Earth’s systems, Schmidt agrees that a few experiments are necessary. “I’m not generally against small-scale field experiments if they help us understand processes in nature,” says Schmidt. “But they should obviously be benign, and we should be very careful.” However, small-scale field tests are also limited, Schmidt believes, with climate simulations possibly being the only way to fully grasp the long-term and large-scale climate effects of geoengineering.
