Seeing Over the Horizon: Sharp Rise in Ocean Temperatures in 2013

February 8, 2014 by Tom Schueneman

What the recently stalled polar vortex over much of the eastern half of the United States makes clear is that we humans are, by nature, not well equipped to think globally. At least not when it comes to their physical surroundings. After all, cold is cold.[read more]

Global Temperatures: What Climate Hiatus?

Climate Hiatus and Oceans

Instead of approaching climate change on the basis of sound science, we are in fact actually jockeying to try to be the last standing amongst the planetary ruins. In this world could there be a more Pyrrhic, egotistical, or fruitless objective?[read more]

UCLA Report: Top 10 Solutions to Global Ocean Plastic Pollution

November 9, 2013 by NRDC Switchboard

Ocean Plastic Pollution

A new report released recently identifies the best solutions to tackle the urgent problem of an estimated 20 million tons of plastic litter entering the ocean each year. Plastic pollution is a daunting crisis for the marine environment, one that demands action.[read more]

Climate Change and Foggy Ideas

 

It is mind blowing that the world’s financial capitals, most of which exist at sea level, so willfully finance the extraction and refinement of the instruments of their own demise while at the same time beggaring the only approaches that have demonstrated potential to safeguard them.[read more]

Ocean Warming, Sea Level Rise And Polar Ice Melt Speed Up, Surface Warming Follows

September 27, 2013 by Joseph Romm

Where Climate Change Happens

Much of the media believes climate change isn’t what gets measured and reported by scientists, but is somehow a debate between scientists and deniers. So we are subject to stories like 'Controversy over U.N. report on climate change as warming appears to slow.'[read more]

Soon President Obama will release his final National Ocean Policy Implementation Plan. With the “new normal” of increasingly costly natural disasters, there is growing recognition of the importance of how we value, manage, and protect our coastal and ocean resources so they can in turn help protect our coastal communities and increase the resilience of local economies.[read more]

Predicting Waves Could Double Ocean Energy Capture

Surfers spend half their time on the water sitting upright on their boards, scanning the horizon for the next suitable wave. The reason of course is that a wave’s size and power is going to tell you a lot about how good a ride you’re likely to have.Well, the same is true of wave energy capture technology. Put simply, some waves are...[read more]

McKibben on the invisible oil slick

May 3, 2010 by Lou Grinzo

Bill McKibben nails it in, Oil Slick You Can’t See Threatens the Entire Ocean: If you think that slick of oil spreading across the Gulf of Mexico is a nasty sight … well, it is. And so we’ll probably do something about it. Within hours of the crude reaching the coast, an aide to President Barack Obama said new offshore drilling would...[read more]

In TCASE (thinking critically about sustainable energy) #5, I analysed a currently deployed technology for harnessing wave energy – the Pelamis device. If you haven’t read TCASE 5 then please do so now, since it explains some of the basic physical properties of wave energy, the extend of the global resource, etc. In writing the following...[read more]

2C or not 2C: Copenhagen and global temperature threshold (Part 1)

December 14, 2009 by Simon Donner

Media coverage of climate change often gives the impression the world’s scientific community all met and firmly established that the warming beyond +2 degrees C is dangerous to the future of society. The planet does not have one clear "dangerous" temperature threshold. Two things needs to be explained clearly. First, the definition of...[read more]

Skeptical Science explains how we know global warming is happening: It’s the oceans

October 10, 2009 by Joseph Romm

The empirical data has spoken. Cancel the global cooling party. Global warming is still happening. The planet is heating up, thanks to human-generated emissions of greenhouse gases.  But as a new NOAA-led study, “An observationally based energy balance for the Earth since 1950” (subs. req’d, release here) concluded: [S]ince 1950,...[read more]

Nature: Ocean fertilization for geoengineering “should be abandoned”

October 4, 2009 by Joseph Romm

In the face of seemingly accelerating climate change, some have proposed tackling the problem with geoengineering: intentionally altering the planet’s physical or biological systems to counteract global warming. One such strategy — fertilizing the oceans with iron to stimulate phytoplankton blooms, absorb carbon dioxide from the...[read more]

Jane Lubchenco interview on NPR: “Ocean acidity has increased by 30%” thanks to human emissions

June 10, 2009 by Joseph Romm

Global warming is a major threat to life in the oceans — and humans who depend on that life (see Ocean dead zones to expand, “remain for thousands of years”).  As one recent study found: Global warming may create “dead zones” in the ocean that would be devoid of fish and seafood and endure for up to two millennia…. Its authors say...[read more]
