We hear the words all over the media… “Global Warming”.
When we hear global warming, it is often referring to to climate change caused by humans and the fossil fuels not only burnt, but trapped in the ozone layer. Climate change is not a new issue, the temperature of the earth has fluctuated many times in the past.
This graph may seem like this is a regular occurrence, but whats alarming is there has been new research suggesting that major catastrophic events occur when climate change is occurring. With this in mind, i decided to investigate when the top 5 catastrophic periods that this world faced occurred.
The 5 extinction events that nearly ended all life on earth, were:
- The Late Ordovician- Occurred 445 million years ago
- The Late Devonian- Occurred 380 million years ago
- The Middle Permian- Occurred 262 million years ago
- The Late Permian- Occurred 252 million years ago
- The Late Triassic- Occurred 201 million years ago
Now do a simple cross-reference to the graph above and you will notice that these periods were very similar to the peaks within the charts.
Whether these dates and the graph is a coincidence is for opinions, there are, however, many scientists that do not believe in this theory.
There is another topic that supports the evidence that we may be in the midst of a extinction period.
As there is hardly any media coverage about animal extinction, other than the occasional save the panda or tigers campaign, I can tell you this is a huge issue.
On March 20 the world lost the last male White Rhinoceros, meaning the hope of natural species re-population has dropped to 0%. There are only two animals left of this species and they are both females.
We are estimated to be losing species 1000X the natural rate.
It is estimated we are losing 150–200 species every day. that’s an incredible 54,000 species disappearing in a SINGLE YEAR.
Close to 15% of all mammal species and 11% of all bird species are currently listed as threatened with extinction.
There is a roughly estimated amount between 20 and 100 million species on this planet if this rate continues and all animal birthing ceases, at the estimated 20 million figure, it would only take 340 years to wipe every animal species of this planet.
That figure does appear significant and far away, but what this calculation has not taken into account is the increased rate in which these extinctions are occurring each year, as indicated by the graph above. The total figure may not be 340 years but rather 100 years with the rate increasing every year.
These figures have led people to believe that we are currently going through the 6th great extinction of this world, which makes sense when comparing that within a century it is quite possible that half of all species on earth may be extinct.
But there may still be hope in such a bleak moment. Just because they are gone does not mean they are gone forever, with advances in biotechnology and molecular genetics, re-birthing using the animals DNA may be possible in the future. The issue is finding suitable animal cells to rebirth these extinct species.
So the question stands, Are we currently facing a extinction period or is the events occurring on this earth the regular cycle of fluctuations that is life?
