Dear reader,

Welcome to SustainAbility in habit, a shared space aiming to grow our ability to sustain the resources our Planet has gifted us with. I hope you enjoy the first and future readings!

The Planet we inhabit has suffered multiple changes and adaptations throughout its history. In the Blog pictures section, you’ll find a graphic I’ve created from different scientific sources, illustrating the main events occurred in the Cenozoic and the Industrial age, including the Anthropocene, along with carbon dioxide (CO2) concentration levels in the atmosphere.

Scientific research along with deep analysis and calculations of Carbon Dioxide concentration in sea water, showed that relatively small changes in Carbon Dioxide concentration leads to exponential changes in surface temperature, due to absorption of outgoing radiation of CO2.

The low CO2 concentration levels during the different Cenozoic’s epochs lead to the cooling of Planet, with the formation and expansion of the Antarctic ice sheet, to the approximate levels known in the Anthropocene. The volcanic activity is one of the factors driving the surge of CO2 Atmospheric levels. Cenozoic’s global warming was reached around 54 million years ago, with CO2 concentration in the interval of 700-900 p.p.m. Scientists attribute the high variability in CO2 concentration levels to the instability of the carbon system during warm periods, but also some possible error in the level of ocean water acidity.

The Anthropocene evidence is of raising CO2 levels along with constant raise in temperatures and continuous reduction of the Antarctica ice sheet level. The Artic has also been melting along with multiple glaciers across the Planet, one of the most well -knowns is the Perito Moreno in the southern hemisphere, not far from Antarctica. If you’ve been there, you know the sound of falling ice blocks is quite impressive and heart breaking! The milky water is beautiful though! I wonder how walking on the glacier is still allowed and a touristic attraction! Our Planet has been changing because most of the humankind has taken an irresponsible approach to the resources the Planet gifted Humankind with. Yet, this approach was not thinking much about the future generations.

As Climate Change effects are hardly deniable with the increase in the frequency of extreme weather events, the wildfires across the globe from California, to Europe and Australia, what steps have you taken in your life to add your grain of sand to new beach we are building? Is it good sand?
