What crisis? Global CO2 emissions stalled for the third year in a row

From the EUROPEAN COMMISSION JOINT RESEARCH CENTRE The annual assessment of global greenhouse gas (GHG) emissions by the JRC and the Netherlands Environmental Assessment Agency (PBL) confirms that CO2 emissions have stalled for the third year in a row. The report provides updated results on the continuous monitoring of the three main greenhouse gases: carbon dioxide…

University of Chicago Air Quality-Life Index

By Andy May The University of Chicago Energy Policy Institute has come up with a new measure of air pollution they call the Air Quality-Life Index or AQLI. It uses particulate pollution concentrations to compute an index that correlates well with expected life expectancy. Particulate concentrations <10 μm (PM10) and <2.5 μm (P2.5) are utilized…

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…

Where did the 2016 El Niño's heat come from?

Guest essay by Mike Jonas 1. The basic physics 2016 was claimed as the “hottest year ever”. Well, the hottest for a few centuries, anyway, if the global temperature measures are to be believed. Let’s suppose that they are. It is known that 2016 was an El Niño year, and that the “hottest year ever”…
