One in six of world's species faces extinction due to climate change – study

One in six of world's species faces extinction due to climate change – study
This article by the guardian basically weighs out the effects of what current rates of global warming will bring us in the relatively near future, the basic statistic that it is focused on is the idea that one sixth of the world’s species will be extinct by the end of the century if the global warming rate is as predicted (4 degrees Celsius).  
The article warns that Australia, New Zealand and South America will be the biggest target of the extinction due to a large number of species being exclusive to their areas, which makes them more prone to extinction, another contributing factor to Australia and New Zealand being so prone to extinction is the fact that the animals have no place to migrate in search of a more suitable climate.
The study used analyses 131 existing study on the topic, to reach the conclusion that at current rates we will lose a sixth of species, the importance of this study is that it is released in a time period prior to a big carbon emission control summit in Paris, in which world leaders will try to forge an agreement to limit carbon emissions. The goal of these meetings is to keep global warming within its safe zone, which is 2c, the issue however is the original deal struck in the summit won’t be able to do that on its own; rather governments would have to take initiative on their own in order to reach to safe zone. No matter the effects of the summit, what has occurred so far in regard to climate change will inevitably take its toll on our species diversity, since even if we achieved the safe zone of global warming it is predicted 5% of species will die out.
Another point to take into consideration is that even the species that may not be extinct will still suffer consequences in regard to their population and distribution, and these effects are not only significant from an environmental point of view but also from the potential issues that could arise on a economic level if the extinctions had a knock on effect and created greater harm to the systems in place in nature which we rely on.
A positive side is that since we understand how long the extinctions may take, it is possible to intervene with some conservation efforts to help the animals that are at risk adapt, nonetheless, it is an indicator that it is due time for some legitimate changes to occur since we are reaching a very dangerous zone in regard to the risks we are handling.

This study emphasizes much of what we already know, but adds a sense of urgency and a call to action to all of us, and helps us understand that the consequences are very real and very present today, thus it is vital that we take them seriously, since we could be living with the complications of environmental abuse sooner than we believed. What I personally like about this article is that it uses statistics in order to truly portray the complexity of what may potentially occur, and also takes varying views of the topic, such as an economic standpoint, which means it could appeal to a wider group of people to all take action rather than exclusively those who associate themselves with conservation and environmental efforts. Also, it is important that the article gives the reader an understanding of the upcoming summit, as well as how important it is for it to be successful, since there could be dire consequences on all of us. Overall, I think that this article shows us that we have already done a lot of damage, but there is no more time to shift reparation attempts to the future, and there is no time to spare when it is our environment and more specifically the biodiversity of our earth at stake.
