If we don’t change the conversation, if we don’t deal with the systemic problems of capitalism and come up with a viable alternative, our goose is cooked.
On Monday November 13th, climate scientists from the Tyndal center for Climate Change Research at the University of East Anglia presented their carbon emissions research to the UN climate negotiators at Bonn Germany. The data were shocking: After three years in which human-caused emissions appeared to be leveling off, global CO2 emissions are now rising again to record levels in 2017. Global emissions are on course rise this year by 2%. China’s emissions are projected to rise by 3.5%. These may sound like small numbers but to climate scientists these are huge because if we’re to keep global temperatures from rising by more than 2 degrees Centigrade, those emissions need to be falling sharply, not just leveling off, let alone rising. Colorado State University climate scientist Scott Denning said “We’ve got to cut emissions by half in the next decade, and by half again in the next two decades, as well. The fact that it’s going up is like a red flag flashing light on the dashboard.”
The same day, the journal BioScience published a letter by more than 15,000 scientists from around the world that looks back at the human response to climate change and other environmental challenges in the 25 years since another large group of scientists published the 1992 “World Scientists Warning to Humanity.”
This time the scientists wrote in part: "Since 1992, with the exception of stabilizing the stratospheric ozone layer, humanity has failed to make sufficient progress in generally solving these foreseen environmental challenges, and alarmingly, most of them are getting far worse." If we don’t take immediate steps, “soon it will be too late to shift course away from our failing trajectory, and time is running out. " The goal of the letter, said William Ripple, distinguished professor in the college of Forestry at Oregon State University, and lead author of the new warning, is to "ignite a wide-spread public debate about the global environment and climate."
Ripple is right. We need a conversation, a global public debate about the global environment and how to save the planet, and we need to begin it right now.
