As sea ice shrinks, Arctic shipping options expand

As sea ice shrinks, Arctic shipping options expand

On October 7, 2013, the Nordic Orion bulk carrier ship completed its journey from Vancouver, Canada, to Pori, Finland, having traveled northward around Alaska and through the Northwest Passage. It was the first large commercial freighter ever to make the voyage through these typically ice-covered Arctic waters. Avoiding the longer journey, through the Panama Canal, … learn more→

China and the Soybean Challenge

China and the Soybean Challenge

Some 3,000 years ago, farmers in eastern China domesticated the soybean. In 1765, the first soybeans arrived in North America, but they did not soon catch on as a crop. For 150 years or so the soybean languished as a curiosity in gardens. Then in the late 1920s, a market for soybean oil began to … learn more→

2013 to be record year for offshore wind

2013 to be record year for offshore wind

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 offshore wind capacity. Before the year is … learn more→

U.S. Carbon Dioxide emissions down 11 percent since 2007

U.S. Carbon Dioxide emissions down 11 percent since 2007

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 the U.S. Energy Information Administration. Emissions shrank rapidly during the recession, then bounced back … learn more→

The global land rush

The global land rush

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 countries, but in a seller’s market, few were … learn more→

U.S. nuclear power in decline

U.S. nuclear power in decline

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 years. Projections for 2013 show a further 1 percent … learn more→

Rising temperature, rising food prices

Rising temperature, rising food prices

Agriculture as it exists today developed over 11,000 years of rather remarkable climate stability. It has evolved to maximize production within that climate system. Now, suddenly, the climate is changing. With each passing year, the agricultural system is becoming more out of sync with the climate system. In generations past, when there was an extreme … learn more→

Chapter 7. Grain yields starting to plateau

Chapter 7. Grain yields starting to plateau

From the beginning of agriculture until the mid-twentieth century, growth in the world grain harvest came almost entirely from expanding the cultivated area. Rises in land productivity were too slow to be visible within a single generation. It is only within the last 60 years or so that rising yields have replaced area expansion as … learn more→

World solar power topped 100,000 Megawatts in 2012

World solar power topped 100,000 Megawatts in 2012

The world installed 31,100 megawatts of solar photovoltaics (PV) in 2012—an all-time annual high that pushed global PV capacity above 100,000 megawatts. There is now enough PV operating to meet the household electricity needs of nearly 70 million people at the European level of use. While PV production has become increasingly concentrated in one country—China—the … learn more→
