Interactive Map Shows World Carbon Dioxide Levels

CO2 Levels

Human activity and the impact upon the world’s climate can now be viewed on an interactive map, with regular updates. The map has been produced by Concordia and relates to a scientific paper published in Nature.

It is based on the confirmatory research that shows the Earth’s temperature has increased by 1°C over the past 100 years. The majority of this temperature increase relates to carbon dioxide emissions (human activity, to date, has led to 600 billion tonnes of these). Carbon dioxide warms the planet through the ‘greenhouse effect’..

The precise finding is that the average temperature increases 1.7 ±0.4°C per trillion tonnes of carbon in CO2 emissions (TtC). Levels varied worldwide according to patterns of industrialization. Higher rises were seen on land compared with the oceans.

Concordia’s research findings are very detailed, and show the impact of human activity on local climate. The map is based on results from 12 global climate models.

Professor Damon Matthews, who works at Concordia University’s Department of Geography, told Laboratory Manager:

“This provides a simple and powerful link between total global emissions of carbon dioxide and local climate warming.  This approach can be used to show how much human emissions are to blame for local changes.”

The basis of the map and the supporting research has been published in Nature Climate Change. The paper is titled “Modelling clean electricity grids in the US.”

While the data is concerning, The Latest News reported last year that global carbon emissions appears to be declining after a century of increasing levels.
