Arctic Sea Ice Freefall is Mirror Image of Carbon Dioxide Ascent

Posted by & filed under Global Warming/Climate Change.

by Emily E. Adams, Earth Policy Institute The amount of Arctic sea ice has plummeted in recent decades — a bold manifestation of the rise in temperature resulting from the rapid increase in carbon dioxide (CO2) in the atmosphere. After staying below 300 parts per million (ppm) for some 800,000 years, the concentration of CO2… Read more »

Less Than 3 Percent of Oceans in Marine Parks Despite Recent Growth

by J. Matthew Roney, Earth Policy Institute Photo credit: Dr. James P. McVey, NOAA Sea Grant Program In May 1975, rising concerns about overfishing and deteriorating ocean health prompted scientists and officials from 33 countries to meet in Tokyo for the first global conference on marine parks and reserves. Noting the need for swift action… Read more »

India’s Dangerous ‘Food Bubble’

Posted by & filed under Biodiversity, Deforestation, Desertification, Food Shortages, Global Warming/Climate Change, Irrigation, Potable Water, Regional Water Cycle, Water Conservation, Water Harvesting.

Editor’s Note: As is often the case with the Earth Policy Institute (EPI), crucial solutions are largely missing from the article below. I personally believe India’s population is not the problem, but land mismanagement and the prioritising of extractive short-term economic policies. The author, Lester Brown, only touches on solutions (a surface-level mention of water… Read more »

Moving Up the Food Chain

Posted by & filed under Consumerism, Health & Disease, Society.

by Lester R. Brown For most of the time that human beings have walked the earth, we lived as hunter-gatherers. The share of the human diet that came from hunting versus gathering varied with geographic location, hunting skills, and the season of the year. During the northern hemisphere winter, for instance, when there was little… Read more »

by Janet Larsen, Earth Policy Institute Super typhoon Haiyan Meteorologists are calling the typhoon that slammed into the Philippines with 195-mile-an-hour winds on November 8, 2013, the most powerful tropical storm to make landfall on record. Super Typhoon Haiyan had gusts reaching 235 miles per hour and a storm surge swelling as high as 20… Read more »

2013 To Be Record Year for Offshore Wind

Posted by & filed under Energy Systems.

by J. Matthew Roney, Earth Policy Institute Offshore wind power installations are on track to hit a seventh consecutive annual record in 2013. Developers added 1,080 megawatts of generating capacity in the first half of the year, expanding the world total by 20 percent in just six months. Fifteen countries host some 6,500 megawatts of… Read more »

U.S. Carbon Dioxide Emissions Down 11 Percent Since 2007

Posted by & filed under Consumerism, Global Warming/Climate Change, Peak Oil.

by Emily E. Adams, Earth Policy Institute The U.S. Annual Carbon Footprint (Chandler 2008) Carbon dioxide emissions from burning fossil fuels in the United States peaked at more than 1.6 billion tons of carbon in 2007. Since then they have fallen 11 percent, dropping to over 1.4 billion tons in 2013, according to estimates from… Read more »

The Global Land Rush

by Lester R. Brown, Earth Policy Institute Between 2007 and mid-2008, world grain and soybean prices more than doubled. As food prices climbed everywhere, some exporting countries began to restrict grain shipments in an effort to limit food price inflation at home. Importing countries panicked. Some tried to negotiate long-term grain supply agreements with exporting… Read more »

U.S. Nuclear Power in Decline

Posted by & filed under Nuclear.

by J. Matthew Roney, Earth Policy Institute Nuclear power generation in the United States is falling. After increasing rapidly since the 1970s, electricity generation at U.S. nuclear plants began to grow more slowly in the early 2000s. It then plateaued between 2007 and 2010 — before falling more than 4 percent over the last two… Read more »

Grain Yields Starting to Plateau

Editor’s Note: As regular readers will know, I don’t agree 100% with everything I post to the site. The article below, for example, has somewhat of a focus on fossil-fuel-based fertiliser, as the means to increasing yields. But, I put this piece up anyway, as the statistical information it contains on plateauing yields is an… Read more »
