John Roulac – Spaceship Earth, Your Main Oxygen Systems Are Collapsing

Yes, Houston, we have a problem: Our oceans are dying. As the brilliant futurist Buckminster Fuller used to point out, our Spaceship Earth is hurtling through space at a great speed. Imagine if someone told you (a passenger on that ship) that the main oxygen systems were failing because of how food was being grown. What would you do upon …

Jeff Tollefson – Antarctica’s Southern Ocean May No Longer Help Delay Global Warming

Joellen Russell wasn’t prepared for the 10-metre waves that pounded her research vessel during an expedition south of New Zealand. “It felt like the ship would be crushed each time we rolled into a mountain of water,” recalls Russell, an ocean modeller at the University of Arizona in Tucson. At one point, she was nearly carried overboard by a rogue …

Camilla Alexander-White – The massive problem of microplastics

In today’s world, plastic is an essential raw material. Since their invention in the 1930’s, plastics have become ubiquitous in the manufacture of everyday products. In 2012 the plastics industry accounted for more than 1.4 million jobs in over 62,000 companies across the European Union.1 As useful and versatile as plastics are, however, their unchecked disposal on an unprecedented scale …

David Biello – Farm the Oceans to Help Stop Global Warming

The Southern Ocean is a forbidding place, mostly unvisited by humans. Winds of more than 120 kilometers per hour wreak havoc, and waves routinely wash up and over the bow of any ship that dares to venture so far south, drenching the decks in ice-cold sea spray that instantly freezes. Worse, rare freak waves can build to towering heights and …

What’s fueling the Clinton campaign?

HILLARY CLINTON couldn’t help but be spitting mad at the Greenpeace activist who confronted her last week about the money her campaign has taken from the fossil fuel industry, asking the candidate if she would pledge to reject such money in the future. “I don’t have–I have money from people who work for fossil fuel companies,” the Democratic frontrunner snapped, …

CSIRO AUSTRALIA – Plastic in 99 percent of seabirds by 2050

Researchers from CSIRO and Imperial College London have assessed how widespread the threat of plastic is for the world’s seabirds, including albatrosses, shearwaters and penguins, and found the majority of seabird species have plastic in their gut. The study, led by Dr Chris Wilcox with co-authors Dr Denise Hardesty and Dr Erik van Sebille and published today in the journal PNAS, …

Ice sheet collapse triggered ancient sea level peak

An international team of scientists has found a dramatic ice sheet collapse at the end of the ice age before last caused widespread climate changes and led to a peak in the sea level well above its present height. The team found the events 135,000 years ago caused the planet to warm in a different way to the end of …

Part of Antarctica has begun thawing unusually fast, leaving scientists unsure whether a natural cycle or human-caused climate change is responsible. By Tim Radford

Antarctic glaciers once thought relatively stable are starting to melt. Evidence from a five-year satellite study of the frozen rivers on the southern Antarctic Peninsula now reveal that these are shedding ice at the rate of 60 cubic kilometres a year: altogether around 300 trillion litres of water has moved from the frozen continent to the oceans. Bert Wouters of …
