In this view of Egypt, we see a population almost completely concentrated along the Nile Valley, just a small percentage of the country’s land area. The Nile River and its delta look like a brilliant, long-stemmed flower in this astronaut photograph of the southeastern Mediterranean Sea, as seen from the International Space Station. The Cairo metropolitan area forms a particularly bright base of the flower. The smaller cities and towns within the Nile Delta tend to be hard to see amidst the dense agricultural vegetation during the day. However, ...

For instance, nighttime lights in some Middle East cities were 50 to 100 percent brighter during the holy month of Ramadan. The maps on this page show changes in lighting intensity and location on the Arabian Peninsula and in the countries along the eastern Mediterranean coast. They are based on data from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite. The maps compare the night light signals fro...

JOHANNESBURG'S gold mining industry was established when a large gold reef was accidentally discovered on a remote farm in 1886, triggering a massive gold rush by thousands of speculators.   The City of Johannesburg is littered with Defunct shafts, Old Mine Workings and Mine Waste Dumps... all a history to the name Egoli - The City of Gold... The Powerhouse of Africa...     Zaheer Bux - Gold Exploration - Central Rand Goldfield Within 10 years, there was a fully fledged town on the same spot; within 30 years it was South Africa's largest city. Today Johannesburg is Africa's biggest city, ringed by the deepest gold mines in the world. The Central Rand Goldfield - Johannesburg Consolidated M...

In 2009, Al Gore followed up with the publication of Our Choice: A Plan to Solve the Climate Crisis , a book that "gathers in one place all of the most effective solutions that are available now and that, together, will solve this crisis". "It is now abundantly clear that we have at our fingertips all of the tools we need to solve the climate crisis. The only missing ingredient is collective will." 00:20:19 One thousand years of temperature history obtained from isotope analysis of ice cores. 00:16:08 Measured since 1958, atmospheric carbon dioxide (CO2) has been increasing steadily. 00:20:53 One thousand years of CO2 and temperature data -- the curves have similar shape. 00:22:49 650,000 years of CO2 and temperature history, from Antarctic ice cores. Dips record ice ages. CO2 concentration and temperature are related. CO2 has spiked upward in recent years. 00:23:53 If no changes are made, CO2 concentration is predi...
