Yet Another Geoengineering Scheme, Ocean Iron Fertilization, Could Backfire

Yet Another Geoengineering Scheme, Ocean Iron Fertilization, Could Backfire | Sustain Our Earth | Scoop.it

Can we save the planet by ruining it (even more)? Argonne National Laboratory reports that “A new study on the feeding habits of ocean microbes calls into question the potential use of algal blooms to trap carbon dioxide and offset rising global levels.”

Four years ago, the journal Nature published a piecearguing that “fertilizing the oceans with iron to stimulate phytoplankton blooms, absorb carbon dioxide from the atmosphere and export carbon to the deep sea — should be abandoned.”

Now Argonne Lab reports so-called iron fertilization “may have only a short-lived environmental benefit. And, the process may actually reduce over the long-term how much CO2 the ocean can trap.”

Great Barrier Reef's condition declined from moderate to poor in 2011

Great Barrier Reef's condition declined from moderate to poor in 2011 | Sustain Our Earth | Scoop.it

An alarming set of reports on the condition of the Great Barrier Reef published on Wednesday say its overall condition in 2011 declined from moderate to poor, and highlights that reef-wide coral cover has declined by 50% since 1985.

The series of reports blame part of the reef's poor health in 2011 on extreme weather conditions including tropical cyclone Yasi, and high rainfall which resulted in "higher than average discharge" from a number of river catchments runoffs.

You can’t deny global warming after seeing this graph

You can’t deny global warming after seeing this graph | Sustain Our Earth | Scoop.it

Nine of the 10 warmest years on record have occurred since 1998. But forget individual years. That data is noisy. A single year can see its temperatures rocket for reasons having little to do with climate change.

Look, instead, at decades. There, the data is a little clearer, as the idiosyncrasies of any one year are balanced by its nine compatriots. That’s exactly what the World Meteorological Association did in a recent report.

North America Will Lead the Worldwide Microgrid Market by 2020 | Caelus Green Room

North America Will Lead the Worldwide Microgrid Market by 2020 | Caelus Green Room | Sustain Our Earth | Scoop.it

With the launch of dozens of successful pilot programs globally, the adoption rate of microgrids is expected to accelerate over the next several years. Microgrids offer greater resilience, a high potential for integrating distributed renewable generation resources, and the ability to isolate themselves, when necessary, from the wider power grid—a capability known as islanding. According to a recent report from Navigant Research, North America is currently the leading microgrid market and will remain the leader through 2020. Total microgrid capacity in North America will reach 5.9 gigawatts in 2020, representing 64 percent of worldwide capacity, the study concludes.

World’s Largest LED Retrofit Saves 80% For GM

World’s Largest LED Retrofit Saves 80% For GM | Sustain Our Earth | Scoop.it

GM’s clean tech cred is pretty well established in the public eye through its popular Chevy Volt, and the company is no slouch behind the factory gates, either. At its Lordstown complex in Ohio, GM can now lay claim to the world’s largest LED retrofit project of its kind. The project involves more than 1,600 fixtures so far with another 4,000 set for installation this summer, and it has already reduced energy consumption by more than 80 percent at one factory in the complex. That’s partly because the LEDs themselves are more efficient and partly because the new fixtures incorporate some advanced energy management bells and whistles.

Wildfires Spit Climate Changing Tar Balls : DNews

Wildfires Spit Climate Changing Tar Balls : DNews | Sustain Our Earth | Scoop.it

Currently in the United States, major wildfires burn in Colorado, Alaska, California, Arizona and near Las Vegas, Nevada. The deadly wildfires torching the western states and other regions may add to climate change more than previously thought.

The discovery of wildfires’ greater global warming threat came after scientists made the best of a burned situation.

In 2011 a wildfire in New Mexico forced the evacuation of Los Alamos National Laboratory. When the scientists returned they collected and studied samples of the smoke and soot from the smoldering fire for more than 10 days.

Contribution of Greenland ice sheet to sea-level rise will continue to increase

Contribution of Greenland ice sheet to sea-level rise will continue to increase | Sustain Our Earth | Scoop.it

New research has shown surface ice melt will be the dominant process controlling ice-loss from Greenland. As outlet glaciers retreat inland the other process, iceberg production, remains important but will not grow as rapidly.   


The Greenland ice sheet is often considered an important potential contributor to future global sea-level rise over the next century or longer. In total, it contains an amount of ice that would lead to a rise of global sea level by more than seven metres, if completely melted.

It’s time for the fourth era of climate change | RTCC Climate Change News | Sustain Our Earth | Scoop.it

Over recent decades the debate about what to do about climate change has been muddied with blame and denial. These twin toxins have poisoned progress at its roots.

It is time for a new way to look at the problem of climate change, a new way to identify solutions. Solidarity is the lens we now need to look through to see clearly where we can move forward together.

James Hansen: Fossil fuel addiction could trigger runaway global warming

James Hansen: Fossil fuel addiction could trigger runaway global warming | Sustain Our Earth | Scoop.it

Nafeez Ahmed: Without full decarbonisation by 2030, our global emissions pathway guarantees new era of catastrophic climate change   

 

The world is currently on course to exploit all its remaining fossil fuel resources, a prospect that would produce a "different, practically uninhabitable planet" by triggering a "low-end runaway greenhouse effect." This is the conclusion of a new scientific paper by Prof James Hansen, the former head of NASA's Goddard Institute for Space Studies and the world's best known climate scientist.

 

"Governments are allowing and encouraging fossil fuel companies to go after every conceivable fuel", said Hansen, "which is an obtuse policy that ignores the implications for young people, future generations and nature. We could make substantial parts of the Earth uninhabitable."
