Several scientists say 2050. But planning our actions with 2050 in mind it may be too careless… What we must keep an eye on is the following figure: 500 ppm. This is the threshold for CO2 concentration in the atmosphere. When overpassed (now we are at around 411 ppm and are growing at a rate of 2.6 ppm more per year) there would be severe climate changes that could make our dear Planet an inhospitable one. Think about yourself….CO2 emissions is a bad habit we seem unable to exit. But we can! And we should do it as soon as possible to ‘mitigate’ climate change effects.
7 billion people! This is a big number, the number of people living on Earth. Projections point to more than 9bn by 2050. One question comes up: Are we too many? How many should we be? It is not easy to give an unequivocal answer. But… some considerations can help us better understand whether we are too many and if we can reduce the footprint of over-population.
Short Termism….the fact that people, businesses and institution make their decisions just taking into account short-term results. More and more conscious economist are pointing the finger at short termism as the main cause of the current economic and social decline (Andrew G. Halden - 2016). In that sense, short termism is damaging human and economic capital in the long term. But there is more…. We strongly think that short-termism is impoverishing cultural, social and “natural” capital: it is the main cause of the current ecological crisis and of the future human crisis.
We all like travelling… But do we know how much impactful are our travelling choices in terms of carbon emissions? In which way can we reduce them? The answer comes from a study conducted by Arunima Malik (University of Sydney ) and a team of researchers from China, Indonesia and Australia. They say 8% of global emissions come from Tourism and that a lot can be done to lessen this percentage.
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.
