Five times in the history of Earth, mass extinctions of unimaginable death scale almost wiped out most of the life on the planet. The last event occurred 65 million years ago when Earth was impacted by an asteroid killing the dinosaurs and other organisms (70 per cent of the species). The deadliest of these extinction events happened more than 252 million years ago. The event is known as the Permian-Triassic Extinction Event or the “Great Dying” that killed around 90 per cent of all species on Earth. This event was caused by a series of volcanic eruptions that released great amounts of Carbon Dioxide (CO2) and other greenhouse into the atmosphere triggering a rapid global warming and climate change. Nowadays, scientists predict that we are moving into another extinction event similar to the Great Dying that can easily destroy the life of every species on the planet, including us. But this time the new event will not be caused by an asteroid or volcanos; it will be human made. After the Industrial Revolution, people have been adding carbon to the atmosphere faster than natural process can remove it causing climate change and increasing the temperature of the planet.
The average temperatures around the globe are rising in shocking pace. In the last 100 years, temperatures have increased only in 1 degree Celsius (a very small number), but 2/3 of that increase have occurred from 1975 until today on an average of .25 degrees per decade. Consequently, each degree we add to our…
