Warming winters: How will the Winter Olympics adapt?

...carbon emissions and sits uneasily with the sustainability strategy of the International Olympic Committee (IOC) which aims to ensure that both the Summer and Winter Games work towards becoming carbon neutral and are aligned with the targets set by the Paris Agreement to keep global warming below 2°C. In comments made during the build-up to the Milano-Cortina games IOC...

Matt Ridley - Stories of Change

...carbon dioxide levels, looked at the Jani equation for how much warming this was likely to produce, and reported it straight, as it were, as a very alarming prospect. I became a little more sceptical in the nineties when I began to look into the science a bit more closely, but then I kind of drifted off and went off and wrote about genes for a number of years and didn’t...

...carbon dioxide (CO2), which must be continuously removed. The process by which O2 and CO2 are exchanged between the body and the environment is termed external respiration. On average, an adult takes between 12 and 18 breaths a minute at rest, exchanging more than 8000 litres of air per day.

Should Economics and the Environment work together?

...carbon emissions and impacts (such as temperature or flooding data) could be used. The figures might not always be easy to generate or perfectly accurate to measure, but these are calculated and accepted as a way of approaching the debate. Many people would challenge the idea that everything can easily be put in to economic terms. Surely there are elements of the...
