Scientists create new method to measure carbon emissions

The methods to measure carbon dioxide emissions and how the soil and the plants they behave with the gases that cause global warming can be improved from a study presented this Monday (16) from the University of Michigan.

"We want to know how to evolve the sources and sinks of carbon, and the only way that can lead to climate change is with scientific information," said Anna Michalak at annual meeting in Chicago, American Association for the Advancement of Science (AAAS, in English).

Global data on gases that cause global warming are the samples at locations scattered throughout the planet and low towers that measure the absorption or release of carbon from a small area of forest.

But these measurements do not coincide with the current computer models of how they behave the plants and soil.

"If we will adapt to climate change, we need the ability to predict what will that change," said Michalak, professor in the Department of Civil and Environmental Engineering, Department of Atmospheric Sciences, Oceanic and Space, University of Michigan.

The researcher reported that "one of the major issues for us is like changing the sources and sinks of carbon." "All this points to the expectation and the administration," he added.

Michalak USA developed a method that the data available to understand the variation of the carbon found on Earth for 50 years and the current levels called "geo-statistical model inverse."

This method divides the world into small regions and examines how carbon dioxide should have been issued in each region to reach concentrations that are measured in points in which samples were taken the weather.

This allows Michalak and his staff use the information that comes from other satellites that observe the Earth's surface and complement the information of the network of air monitoring. (Source: Estadão Online)
