If we do not act to safeguard our planet and stop the gradual global warming caused by greenhouse gas emissions we will face serious consequences which can threat not only the existence of many species but also our same existence and future. A 2018 report from the Intergovernmental Panel on Climate Change (IPCC – a United Nation body for assessing the science related to climate change) focused on the effects of climate change, has provided an alarming scenario concerning these changes in temperatures, and as it has emerged from this report countermeasures taken so far are insufficient to help fighting these changes, and thus protecting our environment.

One of Isaac Newton’s dynamics laws states that ‘for every action, there is an equal and opposite reaction’ and if we apply this law to climate change, what we get is a domino of catastrophic events. To understand why, just take a look at the Report of the Intergovernmental Panel on Climate Change “Global Warming of 1.5 °C”. The Report, made public during the 24th Climate Change Conference held in Katowice (Poland) on December 2018, caused strong controversy and dismay, however it is undeniable that if we do not act rapidly it is likely we will experience severe consequences.

The report, based on the Paris Agreement of 2015 (an agreement containing 196 signatory countries committed to reducing greenhouse gas emissions), focuses on the variables linked to the objective set in Paris, that is, to limit the global temperature increase expected by 2030 to no more than +1.5°C.

It is precisely on these variables that the scenarios developed by the IPCC are based, which describe the effects (on a global scale) of a warming of 1.5°C and 2°C respectively and which we summarize below.
