Burying Crop Residues at Sea May Help Reduce Global Warming

30.01.2009
Imagine a massive international effort to combat global warming by reducing carbon dioxide - build up in the atmosphere.

It involves gathering billions of tons of cornstalks, wheat straw, and other crop residue from farm fields, bailing it, shipping the material to seaports, and then burying it in the deep ocean.

Scientists in Washington and California have concluded that this Crop Residue Oceanic Permanent Sequestration (CROPS) approach is the only practical method now available for permanently sequestering, or isolating, the enormous quantities of CO2 necessary to have a real impact on global warming.

In a report scheduled for the Feb. 15 issue of ACS’ Environmental Science & Technology, a semi-monthly journal, Stuart Strand and Gregory Benford conclude that (CROPS) could reduce global carbon dioxide accumulation by up to 15 percent per year. Plants remove carbon dioxide from the atmosphere during photosynthesis, and release it when they decay. Ocean burial would prevent that carbon dioxide from re-entering the atmosphere.

After comparing known methods for carbon dioxide sequestration on the basis of efficiency, long-term effectiveness, practicality, and cost, the researchers concluded that CROPS is the only method feasible with existing technology. CROPS would be 92 percent efficient in sequestering crop residue carbon. They recommend that crop residue sequestration and its effects on the ocean should be investigated further and its implementation encouraged.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
