The Moon rush is back on. And this time it’s a global race. The USA has promised boots on the lunar surface by 2024. But China already has a rover exploring the farside. India is on the point of sending one too. Europe and Russia are cooperating to deliver more robots. And that’s not to mention the private companies also getting into the competition. Roland Pease looks at the prospects and challenges for all the participants. (Image caption: Chinese lunar probe and rover lands on the far…
These high-res time-lapse sequences captured by astronauts aboard the International Space Station give us a beautiful and clear view of some well-known coastlines and countries around the world. Get a good look at England, France, Italy, Egypt, Algeria, Tunisia, Greece, the island of Crete, Taiwan, South Korea, Japan, the United States, Mexico, Ecuador, Peru, Chile, Argentina, Cuba, and more. We’ve attempted to show as many countries as we would, but inevitably we’ve left many out. Please write to the the astronaut photography office at NASA’s Johnson Space Center to request inclusion in this amazing series of sequences.
Every other Wednesday we present a new video, so join us to see the truth laid bare… A slide from this mountain could kill millions of people in Europe and along Northern America’s eastern seaboard. Some eminent scientists warn that it’s purely a matter of time until it happens. This is the volcanic island of La Palma, 700 miles off the northwest coast of Africa. It’s a new-born baby island barely past its 4 millionth Birthday, created in the last stage of what geologists call the rock cycle. Clip taken from the Naked Science documentary “Landslides”.
Homeowners in a luxury San Francisco high rise are furious over their sinking investment. The 58-story Millennium Tower has reportedly sunk 16 inches since its completion in 2009. Carter Evans reports.
Permafrost refers to frozen soil and water that covers nearly a quarter of the Northern Hemisphere. With climate change warming the Arctic at an alarming rate, the permafrost is beginning to thaw. While this phenomenon can wreak havoc on infrastructure and transportation in places like Northern Alaska and Siberia, the real danger is the release of carbon and methane gas. There are more greenhouse gases trapped in these deep layers of permafrost than all human fossil fuel emissions released since the industrial age. Due to permafrost thaw, that trapped carbon is starting to escape into the atmosphere, creating a warming feedback loop that will make climate change even worse, and cause the permafrost to thaw even faster. If this continues unchecked, scientists warn we could be on the verge of awakening ” the sleeping giant” of climate change. But some innovative climate pioneers are changing that. With the use of both cutting edge genetics, and an experiment that relies on geo-engineering, there is hope that the permafrost thaw can be slowed. VICE Correspondent, Ben Anderson, travels across the Arctic to see the devastating impact of thawing permafrost, and the astonishing solution that might keep it frozen.
On Top Of The World: Greenland’s melting season starts earlier and finishes later than it used to, bringing some major changes to the Arctic island. How are the locals dealing with the shift, and is there any upside?
“If you were to melt the whole Greenland ice sheet here, we’re talking about around seven metres sea level rise”, says Thomas Juul-Pedersen, a senior scientist at the Greenland Climate Research Centre. “There’s always been a melting season, but that melting season seems to dramatically increase”, he says. Since the 1950s, the island’s average temperature has risen 1.5 degrees, bringing droughts and even tundra fires. Now vast swathes of sandy desert sit alongside rapidly melting ice. “It hurts the heart”, says Inuit photographer Adam Lyberth, who has spent 35 years documenting the changing landscape. But while Greenland’s shifting seasons present a huge worldwide threat, for some on the island the warmer summers are a welcome change. “Climate change takes many surprising ways”, says Teunis Jansen, who notes that the first mackerel was caught in Greenland in 2011. To give an indication of the speed of Greenland’s climate change, within just a few years there were 85,000 tonnes of the warm water fish. “It corresponds to about 20-24% of the national export of Greenland”, says Jansen.

From the big red ships that seamen call their “knights” to the smaller white ships that can enter frozen river estuaries, Russia’s icebreakers pave the way through the frozen arctic for commercial vessels and military convoys, allowing passage between Russia’s European ports and the Pacific. They are a reliable and indispensable addition to any trans-Arctic ocean voyage. Join RT as we team up with the crew of one of these amazing nuclear-powered vessels as it traverses the top of the world.
In Basra, where the Tigris and Euphrates join up, 4,000 people a day are admitted to hospital with water related diseases. The reason? Rivers are drying up and the remaining water is salty and heavily polluted. To understand the water crisis in Iraq, an RTD crew travels to the south of the country to see what is happening to Basra’s famous canals. Dr Azzam Alwash, founder of Nature Iraq, the country’s only environmental NGO, takes the crew on a boat tour of the Mesopotamian Marshes, where the buffalo have nothing to drink. Since 2003, the engineer has been fighting alongside the Marsh Arabs to restore the marshlands to their pre Saddam Hussein glory. But can the forces that threaten the water supply be beaten?
Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
