Off the coast of Western Australia, three big buoys floating beneath the ocean’s surface look like giant jellyfish tethered to the seafloor. The steel machines, 36 feet wide, are buffeted by the powerful waves of the Indian Ocean. By harnessing the constant motion of the waves, the buoys generate about 5 percent of the electricity used at a nearby military base on Garden Island.
The buoys are a pilot project of Carnegie Wave Energy, a company based in Perth and listed on the Australian Securities Exchange. In late February, the buoys started supplying 240 kilowatts each to the electricity grid at HMAS Stirling, Australia’s largest naval base. They also help run a desalination plant that transforms seawater into about one-third of the base’s fresh water supply.Full Story
After improving energy efficiency, piloting emissions trading and ramping up renewable energy expansion, China has also been moving on another frontier needed to help ease global warming.
According to a study published recently in the journal Nature Climate Change, the total amount of carbon stored in all living biomass above the soil has increased globally by almost 4 billion tons since 2003, with China contributing in a notable way to the increase.Full Story
It has been well established in numerous studies that the Lebanese passenger transport sector is unsustainable.
This study provides an approach from the cost side of mobility to generate recommendations in order to move the Lebanese passenger transport sector towards sustainable ground. It provides a particular methodology to calculate mobility cost in Lebanon, where data and information are scarce.Full Story
Sea-level rise is accelerating, not declining as some have hoped, scientists said on Monday citing meltwater from Earth's ice sheets as the likely cause.
In 2013, the U.N.'s Intergovernmental Panel on Climate Change (IPCC) said the global mean sea level rose by 19 centimeters (7.6 inches) from 1901-2010, an average 1.7 mm (0.06 of an inch) per year.Full Story
U.S. President Barack Obama's administration on Monday approved petroleum giant Shell's request to drill for oil and gas in the Arctic under certain conditions, despite opposition from environmental groups.
The decision by the Bureau of Ocean Energy Management granted Shell the right to explore the Chukchi Sea as long as the Anglo-Dutch firm gets the correct permits from the agencies that regulate the environment and marine mammal health.Full Story
Safely reaching the UN's climate target requires governments to have a long-term vision that includes carbon pricing, the World Bank said Monday.
A price on carbon dioxide (CO2), the principal greenhouse gas, "is an efficient way to raise revenue while encouraging lower emissions," the Bank said.Full Story
Three sets of scientists in the same week have helped narrow the uncertainties about how the natural world will respond to extra carbon dioxide in the atmosphere caused by the burning of fossil fuels.
Carbon locked in the frozen earth will escape gradually as the Arctic permafrost melts – but the scientists say the process could accelerate.Full Story
Australian Prime Minister Tony Abbott's top business advisor on Friday claimed climate change was a ruse encouraged by the United Nations to create a new authoritarian world order under its control.
Maurice Newman, chairman of the Prime Minister's Business Advisory Council, said the real agenda was "concentrated political authority. Global warming is the hook".Full Story
You’d think it was the ultimate petrolhead paradise, and indeed there is plenty at the Williams F1 headquarters – in an old Johnson and Johnson factory in Oxfordshire – to stimulate the inner Toad. Portraits of drivers Felipe Massa and Valtteri Bottas gaze down from the walls at the F1 car which dominates the reception area, looking, to the uninitiated eye like a high-tech stick insect, while topiary outside depicts a busy pit stop.
But the surprise is that, far from harboring an aggressive Top-Gear-type disdain for all things green, the company is reinventing itself as a champion of environmentally friendly technology. Yesterday it unveiled plans to fit aerofoils developed from racing cars to supermarket fridges so as to save energy, while a fuel-saving F1 flywheel is being tried out in buses. It is even supplying ecologically- correct supercars for the next Bond film.Full Story
If there’s anything to be gleaned about Joss Whedon’s worldview from his hit show Firefly, it might be that he’s pessimistic about the future of politics.
“Nothing will change in the future,” Whedon, who also wrote and directed the enormously successful Avengers movie, once said about the dystopian universe depicted in Firefly. “Technology will advance, but we will still have the same political, moral, and ethical problems as today.”Full Story
