Scientists recently announced the existence of a garbage patch in the Indian Ocean -- the third major collection of plastic garbage discovered in the world's oceans.
Marcus Eriksen, cofounder of 5 Gyres Institute, reports that all of the 12 water samples collected in the 3,000 miles between Perth, Australia, and Port Louis, Mauritius (an island due East of Madagascar), contain plastic.
The five large subtropical gyres (powerful rotating ocean currents) are located in the North Pacific, South Pacific, North Atlantic, South Atlantic, and Indian oceans.
This Indian Ocean garbage patch discovery means there are now three confirmed ocean zones of plastic pollution, and Eriksen and Cummins expect to find others in the South Pacific and South Atlantic gyres also.
Concern about rising temperatures has been growing in recent years as atmospheric scientists report rising temperatures associated with greenhouse gases released into the air by industrial and other human processes.
London, July 14 (ANI): Humans-induced greenhouse gases are increasing sea levels in parts of the Indian Ocean, say experts. NASA-funded researchers monitoring Greenland's Jakobshavn Isbrae glacier report that a 7 square kilometer (2.7 square mile) section of the glacier broke up on July 6 and 7, as shown in the image above. Research teams led by Ian Howat of the Byrd Polar Research Center at Ohio State University and Paul Morin, director of the Antarctic Geospatial Information Center at the University of Minnesota have been monitoring satellite images for changes in the Greenland ice sheet and its outlet glaciers. The researchers relied on imagery from several satellites, including Landsat, Terra, and Aqua, to get a broad view of ice changes at both poles.

WASHINGTON (AFP) – Targets set by policy makers to slow global warming are too soft to prevent more heatwaves and extreme temperatures in the United States within a few years, with grim consequences for human health and farming, a study warned this week. Although the United States and more than 100 other countries agreed in Copenhagen last year to take action to reduce greenhouse gas emissions "so as to hold the increase in global temperature below two degrees Celsius," a study conducted by Stanford University scientists showed that might not be enough. The latest estimate is far higher than the 2.65 billion dollars given by the energy firm one week ago. After intense pressure from President Obama over the worst ever US environmental disaster, BP agreed last month to suspend its shareholder dividend and create a 20-billion-dollar fund for costs arising from the spill. Here's what you need to know about ?the warming planet, ho??w it's affecting us, and what's at stake. The evidence that humans are causing global warming is strong, but the question of what to do about it remains controversial. Earlier and increased pollen production and worse smog have been linked to increased CO2 levels. Scientists are working with mud, ice, and more, trying to figure out the workings of the climate before and after people appeared. The team works in collaboration with Algalita Marine Research Foundation and Pangaea Explorations.

Once plastic makes its way into the ocean (through sewers, streams, rivers, or from the coast), it is ultimately swept up and trapped in these gyres and forms a swirling soup of garbage. The 5 Gyres Institute, a team of scientists and educators, will lead eight expeditions to explore the South Atlantic (starting later this summer) and South Pacific (scheduled for next spring). While this week's breakup itself is not unusual, Howat noted, detecting it within hours and at such fine detail is a new phenomenon for scientists.
Then, in the days leading up to the breakup, the team received images from DigitalGlobe's WorldView 2 satellite showing large cracks and crevasses forming. BP's share price has collapsed more than 50 percent since the Deepwater Horizon oil rig it leased sank on April 22, two days after a blast that killed 11 workers. Economics, sociology, and politics are all important factors in planning for the future.Even if we stopped emitting greenhouse gases (GHGs) today, the Earth would still warm by another degree Fahrenheit or so.
