Construction needs cloud flexibility

Australia’s embattled construction sector could benefit from cloud based information systems that can be switched on and off in lockstep with individual projects – with the exception of those organisations based in remote areas like the Kimberleys.

One good thing about global recession: Less pollution

Science - Climate

A study published in the journal Nature Geoscience states that the global economic recession has done one positive thing. It has reduced carbon dioxide levels for the first time in ten years.


The November 21, 2010 paper, entitled 'Update on CO2 emissions' (doi: 10.1038/ngeo1022) is authored by P. Friedlingstein, R. A. Houghton, G. Marland, J. Jackler, T. A. Boden, T. J. Conway, and other colleagues.

The authors state that pollution from carbon dioxide, one of the Earth-warming greenhouse gases, decreased from 2008 to 2009 by 1.3 percent.

The lead author in the study, Pierre Friedlingstein, from the University of Exeter, the United Kingdom, stated, "The good part of the crisis is that it reduces emissions." [Associated Press: 'Weak world economy cuts carbon pollution last year']

Friedlingstein further specified that, in 2009, 31 billion metric tons (34 billion tons) of carbon dioxide (CO2) was injected into the atmosphere by human activities, such as driving gasoline-powered vehicles and making products in factories.

In 2008, the world output of carbon dioxide was higher by 453 million tons.

According to the Associated Press article, the last time that the amount of carbon dioxide decreased from one year to the next was in 1999, and before that, in 1992.
