Scientists discover massive underwater rivers in the Black Sea

An underwater river that dwarfs the Thames has been discovered in the Black Sea.
Europe’s giant inland sea contains currents that behave much like rivers do on land. Scientists from the University of Leeds explored these never seen before currents with a robotic submarine. The currents are created by salt water flowing into the Black Sea from the Mediterranean through the Bosporus Strait.
These currents may provide vital nutrients to sustain sea life that exists far from the nutrient-rich waters of the sea that lie close to land.
It flows down the sea shelf and out into the abyssal plain much like a river on land. The abyssal plains of our oceans are like the deserts of the marine world, but these channels can deliver nutrients and ingredients needed for life out over these deserts.
–Dr Dan Parsons, Leeds University School or Earth and Environment.
One of the largest known channels – believed to be formed by currents or underwater rivers of this kind – is located off of Brazil’s coast, where the Amazon meets the Atlantic. The undersea river in the Black Sea, however, is the only one found to be still flowing.

UN report: Third of Earth’s plant and animal species under threat of extinction
Economic growth and the quest for raw materials in developing nations are threatening to devastate global biodiversity, according to a forthcoming UN Global Biodiversity Outlook report. Ahmed Djoghlaf, head of the Convention on Biological Diversity is reported as claiming the current rate of extinction to be 1,000 times its 'natural historical background rate'. From an article in the Telegraph: Population growth, pollution and the spread of Western-style consumption are also blamed for hitting plant and animal populations. The dangerous behavior already practiced by industrialized...
Preparing for the worst: Climate change adaptation
Inevitable changes in climate mean the vulnerable must adapt or suffer the worst consequences of climate change. Even climate skeptic Lord Lawson, who is not convinced that human activity is the main cause for climate change, supports aiding poorer, vulnerable countries to prepare for and deal with coming adversities. In a CNN 'climate change debate' with Lawson, Nobel Peace Prize winner Wangari Maathai agreed that poor countries must prepare for the worst and should not expect agreements at COP15 to...
European companies support climate change deniers in the U.S.
A report from the Climate Action Network (CAN) states that a number of European companies are supporting climate legislation blockers in the U.S. by funding the campaigns of republican candidates to the U.S. Senate. The CAN came to this conclusion by analyzing publicly available campaign finance records. The Climate Action Network reviewed financing streams from a number of candidates that are actively lobbying against climate change legislation. Their findings are that a number of big European industrial companies already spent a...
Study shows smokers are less intelligent
A study of over 20,000 Israeli military recruits suggests that smokers have lower IQs than non-smokers. Reuters reports on the Israeli study, which takes a different approach to previous studies by attempting to exclude subjects with mental and behavioral problems. To better understand the smoking-IQ relationship, the researchers looked at 20,211 18-year-old men recruited into the Israeli military. The group did not include anyone with major mental health problems, because these individuals are disqualified from military service. –Reuters According to the findings, the average...
Kids Can Help the Environment, Too
So many people place the emphasis of helping the environment or finding a “cure” for the Global Warming crisis on adults. World leaders, scientists, business CEO’s and even parents are constantly pressured to find solutions or “set a good example” for future generations to live by. What they apparently do not understand is with all the environmental problems we face today, age does not matter; everyone must do their part to help. While not everyone is as lucky as Bindi Irwin...

And a raging debate on the genetic engineering of crops ensues! Paul Collier, economist, Oxford University – 'Put aside Prejudices' The debate over genetically modified crops and food has been contaminated by political and aesthetic prejudices: hostility to U.S. corporations, fear of big science and romanticism about local, organic production.

Climate change adaptation: Floating schools in Bangladesh
The South Asian country of Bangladesh is one of the places in the world considered most vulnerable to climate change. It is also one of the poorest nations on Earth. In Bangladesh, reducing CO2 emissions and implementing cap and trade schemes are not the issue. Already used to catastrophic flooding compounded by intense poverty, Bangladeshis are in the business of climate change adaptation. This is climate change ground zero. As Himalayan glaciers melt and heavy rains perennially flood Bangladesh – a hot country...
Deadly mudslides in Rio de Janeiro, Brazil
According to a BBC News report around 50 people have died in mudslides brought on by heavy rains in and around the Brazilian city of Rio de Janeiro. Mudslides frequently threaten densely populated 'favelas' or shantytowns, which are often built on hillsides in the Rio region. But it is not only the poor residents of Brazil who are falling victim to Mother Nature. The nearby island resort of Ilha Grande has seen deaths and injuries from the collapse of a...
