Examining the Carbon Dioxide Cycle

Guest essay by Ronald R. Cooke Introduction In high school and college I did reasonably well in the physical sciences: chemistry, physics and geology. From these studies one can learn that carbon (C) is an element, is widely available throughout our universe, is chemically active (which means many inorganic and organic compounds include carbon), is…

Two Competing Narratives on Carbon Dioxide

Is carbon dioxide our friend or our foe? Guest essay by Iain Aitken Here is a dossier of key facts about carbon dioxide (and its role in global warming): · It is an incombustible, colourless, odourless, tasteless and non-toxic gas · It is a plant nutrient and, as the ‘fuel’ of photosynthesis and the creation…

Surprising: NASA’s Global visualization in 3D of Carbon Dioxide in Earth’s Atmosphere

From NASA Goddard via the OCO-2 Satellite Carbon dioxide is the most important greenhouse gas released to the atmosphere through human activities. It is also influenced by natural exchange with the land and ocean. This visualization provides a high-resolution, three-dimensional view of global atmospheric carbon dioxide concentrations from September 1, 2014 to August 31, 2015.…

Dueling press releases: Plants have been helping to offset climate change, but now it’s up to us

Our previous story, Study suggests increased atmospheric CO2 creates a 30% growth in plant photosynthesis during last two centuries look almost entirely different than this press release from the CARNEGIE INSTITUTION FOR SCIENCE on the very same study. Plants have been helping to offset climate change, but now it’s up to us Findings affirm estimates used in…

Study suggests increased atmospheric CO2 created a 30% growth in plant photosynthesis during last two centuries

From the UNIVERSITY OF CALIFORNIA – MERCED and the “CO2 is plant food, but, it’s still terrible department” (see text) Research shows global photosynthesis on the rise Plant photosynthesis was stable for hundreds of years before the industrial revolution, but grew rapidly in the 20th century, according to new research published today in Nature. “Virtually…
