Eating Bugs Helps Curb Both Hunger And Climate Change

The Food and Agriculture Organization of the United Nations recently suggested that eating bugs (yes, insects) could help feed the world’s fast-growing population. Along these lines, Anna Jansson, professor of animal science at the Swedish University of Agricultural Sciences, has shown how nutrient-rich insects can make a big contribution to diet in poor countries. Surprisingly, they can also help […]

World Forest Problems Include Deadly Fragmentation

  When environmentalists, farmers, and loggers speak about forests, the discussion usually revolves around the issue of deforestation, which is one of the largest contributors to climate change. As James Ayre pointed out in a recent PlanetSave article, forest cover estimates are currently a subject of hot debate because a new satellite imaging study contradicts the […]

A Message About Your Water Bottle

Aquafina, Dasani, and Poland Spring are names on the water bottle that have come to evoke images of pristine waterfalls, swift cool streams, and shimmering, unspoiled mountain lakes. As well they should. These three carefully selected names are among the largest selling brands of bottled water in the United States. They play a vital role […]

What Is Climate Change? (VIDEO)

Remember the difference between weather and climate? We know what happens when the weather changes—it’s obvious. Climate is another story. Read on. When it rains, you put on a raincoat or take your umbrella when you go out. It snows: time for high boots, a heavier coat, scarf, and warm gloves. And sunny days, well, […]

Climate Synthesis Sent To World Leaders By IPCC

Or do you? It’s time to pay attention to climate change now—as if it wasn’t back in 1800, when our current problems started. We all need to acknowledge that stunning industrial achievements can carry with them enormous unforeseen risks and challenges. Americans should take particular note, because on the whole we are wa-a-a-y behind on this.

OCO-2 Set To Outfox Climate Change Denial

OCO-2 is only a little thing, about 6 ft long, 3 ft in diameter, and less than half a ton in weight (NASA/JPL-Caltech, artist’s conception).  It will be harder to deny the existence of climate change now that NASA has successfully launched Orbiting Carbon Observatory-2.  A United Launch Alliance Delta II rocket from Vandenberg Air […]

Watch Cousteau Ocean Climate Study LIVE in June! (videos)

Fabien Cousteau, ocean explorer and grandson of famed Jacques-Yves Cousteau, began a historic subsea mission on Sunday. He’s studying ocean impacts of climate change (especially acidification, which occurs as the sea absorbs atmospheric carbon dioxide), effects of plastic and other pollution on marine life, and overfishing of marine resources, which diminishes the ocean’s biodiversity. You […]

"Clean Gas" More Dangerous Than Coal, Industry Expert Tells TV

US “clean gas” wells in operation (Irekia-Eusko Jaurlaritza in blogs.lse.ac.uk) Turns out that just about everyone (including President Obama) has been hugely underestimating the methane pollution levels of so-called “clean gas.” The booming American economy now seems to come at a greater cost than we originally thought when we found out that natural gas produces […]

National Climate Assessment Pulls No Punches About US Options

(All figures are from the 2014 National Climate Assessment draft.) Later today (Tuesday, May 6), at 8 a.m. EDT, the National Climate Assessment and Development Advisory Committee of experts meets by conference call to approve the final version of the Third National Climate Assessment. The gist of their message, as Suzanne Goldenberg of The Guardian […]

Climate Change as a Global Game of Tetris (Video)

One way of getting the message of global climate change across to people in a simple and easy to understand manner is to compare it to something that’s a lot more accessible to them, such as a video game, and in this case, Joss Fong uses the Tetris to explain how CO2 emissions affect the […]

The IPCC's Blockbuster 5th Climate Assessment

BREAKING: Late this evening (8 pm EST, or tomorrow, March 31, at 9 am in Tokyo), something large and unpleasant will hit the fan about climate change. At a press conference in Yokohama, the Nobel Prize-winning Intergovernmental Panel on Climate Change will release its Fifth Assessment Report on impacts of human activities on current and […]

Funding More Fire Suppression Won't Do The Trick

A firefighter pauses at the $2013 Rim Fire in Yosemite National Park, August-September 2013 (Calfire photo on facebook). President Obama released the federal budget for 2015 last week. Overall, it involves the lowest deficit ($514 billion) of his five-year tenure in office and restores some funding cut in last year’s sequester. Parts of the new […]

Gas Pipeline Nixed In Pinelands Reserve… For Now

“Truly a special place,” says the National Park Service online guide. (Pictured: the Mullica River, from wiki commons). The fragile environment of the New Jersey Pinelands gained a rare win this month over development pressures, as represented by the governor, the utility industry, and multistate corporate interests. Lane closures last fall on the George Washington […]

UN Nails Forest Risks, Strategy In Warsaw With REDD+

At the late November meeting of UN climate delegates in Warsaw, negotiators from Canada–once a strong supporter of fast-start financing to limit greenhouse gas emissions from developing countries–and Australia, now led by a rashly conservative government, sat on their hands. Reeling from the costs of mitigation at Fukushima and a stopgap return to fossil fuels, […]

Shutter 1.2% Of Power Plants, Cut Carbon Costs By 20%

The nation’s most-polluting power plant, Georgia Power Company’s Plant Scherer in Juliette, Georgia, emits more carbon dioxide than all of Maine’s energy emissions. Here’s more from Environment America: On September 10, the Environment America Research & Policy Center, an independent nonprofit, and the Frontier Group presented a mighty appealing fast track toward limiting the U.S. […]

NOAA’s Mauna Loa Observatory Sees 400ppm Carbon Dioxide Levels

Atmospheric carbon dioxide concentrations have been closely monitored for some time now. Just last month it was predicted that if we did not break through the 400 parts per million (ppm) barrier this May, it would happen next year, according to the longest continuous record of carbon dioxide levels in the atmosphere. On May 9, true […]

Cutting Emissions Of Certain Pollutants Could Slow Down Sea Level Rise

New research has shown that rising sea levels could be greatly slowed if certain fast cycling pollutants are cut from the numerous emissions being pumped into the atmosphere. According to the research, published in the journal Nature Climate Change this week, cutting levels of methane, soot, refrigerants, and gases that lead to the formation of ground-level ozone, […]
