...carbon dioxide − but risks increasing climate change effects abroad...[Path in the Dromore Wood Nature Reserve, County Clare, Ireland] British scientists have worked out how to turn agricultural land – which currently produces 10% of the nation’s greenhouse gas emissions – into a “carbon sink” that soaks up carbon dioxide. The answer is simple: take more land...

...carbon dioxide (CO2). Carbon dioxide is a colourless odourless gas that dissolves in water under pressure. The carbon dioxide forms a very weak carbonic acid, (H2C03) which causes the tingly sensation on your tongue. The amount of carbonic acid created depends on the pressure.

...carbonates, and especially sulphates. These minerals originate when water and rocks interact with each other, resulting in the dissolution of the rock, and upon evaporation, a salt deposit appears – this is why we call these rocks evaporites. Life is nothing but a series of chemical reactions that happen inside of cells, and these reactions can only take place in...

...carbon emissions it was the other way round - operational carbon was starting to be seen as important, but no-one was talking about the capital (‘embodied’) carbon of construction. In 2007 I moved into academia where I have now researched and written about embodied carbon of buildings - only one part of what we need to think about for our built environment, as we face...

...or carbon and nitrogen together, in a medium of gas, solid or liquid, are diffused into the surface of component(s), particularly those made from low carbon steels. Changes to the chemical composition of the surface (austenite) lead to high carbon content in the surface material, which when quenched transforms to a hard coating (martensite)...[Images to demonstrate...
