CO2 Emissions Continue Significant Climb

26.11.2009
The annual rate of increase in carbon dioxide emissions from fossil fuels has more than tripled in this decade, compared to the 1990s, reports an international consortium of scientists, who paint a bleak picture of the Earth’s future unless “CO2 emissions [are] drastically reduced.”

These CO2 emissions increased at a rate of 3.4% per year from 2000 to 2008, in contrast to 1% each year in the previous decade, scientists from the Global Carbon Project report in the current issue of Nature Geoscience. The team comprises some 30 researchers from around the world, including Scott C. Doney, senior scientist at the Woods Hole Oceanographic Institution (WHOI) and Richard A. Houghton, senior scientist and acting director of the Woods Hole Research Center (WHRC).

Since 2000, the scientists documented an overall increase of 29% in global CO2 emissions. They attributed the rise to increasing production and trade of manufactured products, particularly from emerging economies, the gradual shift from oil to coal and the planet’s waning capacity to absorb CO2.

Doney led a team that developed ocean-model simulations for estimating the historical variations in air-sea CO2 fluxes.

“Over the last decade, CO2 emissions have continued to climb despite efforts to control emissions,” Doney said. “Preliminary evidence suggests that the land and ocean may be becoming less effective at removing CO2 from the atmosphere, which could accelerate future climate change.”

A key element of the report, according to Doney, was the work of Houghton, acting director of WHRC. “He developed the estimates of carbon emissions from deforestation, a major source of human-driven carbon emissions,” Doney said.

“Although the emissions of CO2 from deforestation accounted for only about 15% of total CO2 emissions over the period 2000-2008, reducing deforestation is one of the activities that could contribute significantly to stabilizing the concentration of CO2 in the atmosphere,” Houghton said. Negotiations at COP-15 in Copenhagen next month will take up this issue in earnest.

WHOI and WHRC, along with the Marine Biological Laboratory, make up the Woods Hole Consortium, an alliance that focuses on the interlocking issues of climate change and ecosystems health and human well-being.

The Woods Hole Oceanographic Institution is a private, independent organization in Falmouth, Mass., dedicated to marine research, engineering, and higher education. Established in 1930 on a recommendation from the National Academy of Sciences, its primary mission is to understand the oceans and their interaction with the Earth as a whole, and to communicate a basic understanding of the oceans’ role in the changing global environment.

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
