We are the last generation... [Part 2]

Here is what I came up with so far. Your constructive comments are very welcome!
As you can see, this is an environmental awareness poster, where I tried to illustrate the UN Secretary General Ban Ki-moon's quote stating: "We are the last generation that can fight climate change. We have a duty to act." This poster is supposed to remind everyone that we do not have much time to think whether global warming exists. Planet Earth is already warming up, and ice glaciers are continually melting, thus increasing the sea level. If this process continues, it is projected that small island states will soon start sinking. Then coastal regions of many countries will also be negatively affected. The year of 2015 is reported to be the hottest year since the beginning of the meteorological recording. The worst case scenario of global temperature rise projected by the International Panel on Climate Change is 4-8 degrees Celsius. If this forecast comes true, the world will face challenges of the tremendously negative impact that we, as humanity, will not be able to fix. Therefore, the message of this poster is clear. It is calling for urgent actions to save our planet... before it is too late.
