The United Nations says we could have just 12 years left to limit a climate change catastrophe. The climate emergency has resulted from humans putting additional greenhouse gases in our atmosphere. These have heated our planet and at current levels are already a true disaster on a global scale. Unless removed, these gases will result in a level of global warming that will be catastrophic for humanity and much of the world's remaining ecosystems. http://www.caceonline.org/what-is-the-climate-emergency.html
