Scientists Develop a way to Trace and Track CO2 Underground
Image Source: Stock.Xchng. By: Z_reinhart.
Why underground? Well, consider that a lot of emissions come from power plants—coal plants and the like—so, scientists started investigating underground caverns, fissures and coal beds to find places where those emissions can be stored; thus reducing the amount of greenhouse gases in the atmosphere.
So, how do they find and track the carbon? They used colorless, non-toxic liquids called perfluorocarbon tracers. These tracers were used to fingerprint CO2 that was injected into a coal seam in New Mexico. By tracking the tracers, they were able to follow the movement of the CO2.

U.S. Midterms: Or when Democracy takes a blow to the head
After yesterday’s elections, president Obama lost his majority in the House of Representatives. A power shift is unavoidable. Republicans campaigned loud and hard, promising they would put an end to president Obama’s economic reforms and to his healthcare politics. Republicans are also everything but climate change believers. President Obama’s green agenda, and especially his climate and energy policy now seem to be in jeopardy as well. But let’s take a step back for a minute and consider how and why...
North Carolina Bans Plastic Bottles from Landfills
It would seem that the state of North Carolina has taken a great step in the world of recycling. Apparently, they are now banning plastic bottles from landfills. The good news is 95% of North Carolina residents have access to recycling centers and all this mandatory recycling has provided over 14,000 people with jobs. There has also been a rise in the amount of recycled plastic bottles. Counts are now up to an average of 19,000 a month. The bad news is...
Breaking News: China’s Yellow River may be Threatened by Oil Spill
Last week, an oil pipeline burst in northern China, causing one major oil spill. Thousands of gallons (liters) of diesel flowed into a main tributary of the Yellow River. The pipeline, operated by CNPC (China National Petroleum Corporation), is located near Shaanxi province and is used to transport diesel from Gansu province in the northwest to the more centralized places in the country. Investigations show that the bursting was caused by a local construction project. To make matters worse, oil has already...
New NASA video of aurora borealis released
The aurora borealis, or ‘northern lights’ is an amazing phenomenon that occurs when a solar wind of charged electrical particles enters the Earth’s magnetic field. When these particles hit the Earth’s upper atmosphere above the Arctic region, the atmosphere produces an incredible spectacle of spectral multi-colored lights that ‘dance’ in the night sky. NASA has recently released a time lapse video composed of some 500 photographs of the aurora borealis taken by digital cameras on the International Space Station. From BBC News: By...
Rice and climate change: A vicious circle
Rice farming in its present state is water intensive and greenhouse gas producing – from methane released by bacteria and from fuel burnt during farming and shipping. The production of rice is also often destructive to crucial natural resources like mangrove forests, which function as carbon sinks and natural flood defenses. Since the cultivation of rice contributes to environmental degradation and climate change it is – ironically – a threat to itself. Changing temperatures and more extreme weather threaten the livelihood...
Salting roads kills frogs and other wildlife
Frogs can't seem to get a break. Yet another enemy of the vulnerable amphibians – at least in cold countries – is sodium chloride, or NaCl, which is used in many parts of the world to grit icy roads in the winter in order to make them more drivable. The problem is that it's toxic to aquatic animals and plant life – especially frogs. This becomes an issue as soon as the weather warms up and the snow and ice...
Sea Shepherd Updates: An Interesting Turn of Events
One interesting turn of events certainly deserves another. Last week, it was announced that anti-whaling activist, Captain Pete Bethune, would be heading back to his New Zealand home. The Japanese court sentenced him to 2 years in jail, but that sentence was also suspended for 5 years, which means if he can stay out of trouble with Japanese authorities for the next 5 years, he will continue to be a free man. Over the weekend, it was announced that Bethune was deported...
“Super-Smart” Grid may Provide Europe with Electricity from Completely Renewable Sources by 2050
Do you live in Europe? If you do, I have a bit of good news for you. PricewaterhouseCoopers announced that all of Europe’s electricity needs may come completely from renewable energy sources by 2050. According to the report, the goal is to create a “super-smart” grid. This grid will be powered by solar farms in North Africa, wind farms in Northern Europe (including the North Sea) and hydro-electric power from the Alps and Scandinavia. That kind of grid would make carbon-based...
US vs. China and low expectations characterize climate talks
The UN climate talks currently underway in Tianjin, China are smaller, more subdued and well organized when compared to the major international event at Copenhagen last December. But in the end they are still about China vs. the United States. Tianjin is being seen as an opportunity to find some common ground before the UN summit in Cancún, Mexico later this year, but the chief US envoy is frustrated at the level and speed of progress taking place. Instead of actual progress...
‘Nasca Lines’ explores the mystery of Peru’s ancient geoglyphs
The documentary 'Nasca Lines: The Buried Secrets', currently airing on the National Geographic Channel, uncovers the mysteries surrounding an ancient and fascinating series of designs carved into the floors of the Nasca – or Nazca – Desert in Peru. The lines depict simple designs as well as more elaborate representations of animals and are as large as 200 meters (600 ft) across. They are believed to be the creations of the Nazca people, a pre-Colombian culture that existed in southern Peru...
