Ocean Carbon Uptake. This is the expression used by scientists to explain how much CO2 emitted is absorbed by Oceans. Knowing the rate at which the oceans absorb carbon pollution is a key to understanding how fast climate change will occur. This is what a group of scientists, led by Tim DeVries is trying to do. On the other hand, understanding the impact of CO2 ocean uptake have in terms of ocean acidification is important too. Let’s see how Ocean Carbon Uptake work and how it is measured.
It all started in the mid-20th century: Murray Bookchin, an anarchist theorist and former Marxist, began to develop a framework called “Social Ecology” as a way to understand how the environmental disaster has its origins in hierarchy. Is he right?
Almost all of us (perhaps 100% of the alphabetic population) know that Climate Change is caused by an increase of carbon dioxide (CO2) in the atmosphere and that this is largely caused by the combustion of fossil sources (coal, oil, gas)... But What are the sectors which “emit” more? What the countries? Let's see ... but first ....
Climate Change has given birth to a big, global debate over the past 30-40 years. Although the scientific community, thanks to the numerous reports by the IPCC (Intergovernmental Panel on Climate Change), agrees on the facts that 1) climate change exists, 2) climate change is caused by anthropogenic factors (by humans), 3) Climate change over the last 200 years has accelerated considerably (it is estimated that Cliamate Change is 170 times faster than in pre-industrial times), there are still people who deny these statements; they claims that climate change is natural and we cannot do anything to change the course of events. This article proposes an analysis of the three major measures (consequences/results) of Climate Change (CO2 concentration in the atmosphere, Global temperature, Arctic ice extent). It’s interesting to note that these three measures converge in one direction: Earth moves towards overheating with tight rhythms.
When one first meet the expression Doughnut Economics, he may think of a joke, or perhaps an economic model for managing the supply or the purchase of food. It is not the case! The Doughnut Economic Model proposed by Kate Raworth is a very deep, at the same time philosophic and pragmatic, approach towards the matter of sustainable economy. Thinking that there are 2 lines, 2 limits, 2 boundaries, that, when overpassed, could trigger a serious of nefarious things for human development is very valuable and of practical use for citizens, academics, firms and institutions. Kate Raworth, in her book Doughnut Economics, Seven Ways to Think Like a 21st Century Economis, explains clearly the basics for sustainable development.
