News — Carbon Dioxide (CO2)

If you’re looking for something fun to do together with your kids, family or friends this season; why not try these fun and spooky experiments with CO2? 

Scientists have discovered a new type of bacteria that could redefine what they know about the marine carbon cycle on the ocean floor.

What if capturing or reusing atmospheric carbon dioxide was a profitable business? Instead of using tax dollars or carbon capture credits, industry would seek out new ways to make money - and jobs - with the added benefit of reducing global CO2 levels.

The recently remodeled Dollard-des-Ormeaux Civic Centre in Quebec, Canada uses a carbon dioxide refrigeration system to freeze the floor of the ice rinks as well as provide building heating. The details of this project were published in a paper titled “CO2 Showcase for Ice Rinks, Pools” by Kateri Heon and Pietro Guerra from exp. Inc. in the August, 2015 ASHRAE Journal. According to the authors, what immediately emerged from the study was that: CO2 offered significant advantages for the project, compared to ammonia. This is despite ammonia compressors having an average coefficient of performance (COP) value of 3.45, which is...

Guest post by Michael Forster, Edaphic Scientific Pty Ltd Everyone knows that plants need carbon dioxide to grow. But fewer people know that carbon dioxide can also effect plant transpiration and even the water balance of entire ecosystems and catchments. Even fewer people know that carbon dioxide can affect biodiversity and which plant species are more common than other species. Let’s just leave aside all of the topics on how increasing carbon dioxide is leading to global warming and how this, in turn, is impacting on plant species. Let’s just focus purely on how increasing atmospheric carbon dioxide changes the...
