Throughout the Bonn talks, representatives of some of the most vulnerable nations to climate change pleaded with high-emitting nations to reduce their greenhouse gas (GHG) emissions in light of the current suffering of their citizens. Among others I talked to early during the Bonn talks was a representative from Seychelles, a nation of 115 islands about 900 miles East of the East African coast in the Indian Ocean, who was strongly disturbed by the US lack of response to climate change given that people on her island were already suffering from rising sea levels and drought which was making it more difficult for her island nation’s citizens to grow food.
I also talked to Africans working on climate issues who claimed that massive human suffering from drought is now visible in the sub-Sahara countries of Mali, Chad, and Niger, suffering which is responsible for the creation of waves of refugees who have been attempting to enter Europe often through Libya, many of whom have drown at sea while those of have made it to Europe are destabilizing European politics.
Throughout the Bonn negotiation complex, most nations mounted pavilions which included displays of climate change impacts already being experienced in their countries, adaptation responses which are underway, and mitigation efforts which they are undertaking. Walking through the Bonn complex, participants could not escape the conclusion that adverse climate change impacts are not just a future menace but a troubling current reality in much of the world. Although ten years ago, one could participate in the yearly climate negotiations and conclude that most nations thought that human-induced climate change was mostly a future threat, in November 2017 it is clear that most nations are already experiencing some adverse climate change impacts that they realize they and other nations need to respond to now.
In several Bonn events, representatives of the global scientific community created a mood of gloom and urgency by discussing the magnitude and speed of GHG reductions now necessary to prevent catastrophic climate change harms. One program put on by the United Nations Environment Program (UNEP) described the enormous gap between the GHG emissions reductions pledged so far by nations under the Paris Agreement and those that are required to limit warming to the Paris Accord’s goals of 1.5 to 2.0 degrees C. A report by UNEP concluded that if the international community fully complied with its GHG emissions reduction pledges made so far, the gap between the pledges and what is needed to achieve the warming limits is “alarmingly high.” The report goes on to say that even if national pledges are fully complied with, the remaining carbon budget that must constrain global GHG emissions to limit warming to 2.0 degrees C will be 80 % depleted by 2030 while by that year the remaining budget to achieve 1.5 degrees C warming limit goal will have been completely depleted. The report also says much more ambitious national pledges are now necessary by 2020, just over two years from now, to have any realistic hope of staying on a reduction pathway necessary to achieve the Paris Agreement’s warming limit goals.
Other scientists during the Bonn negotiations alarmingly warned of the more rapid loss of Arctic ice than what was expected, increasing yearly larger rises of atmospheric CO2 concentration levels perhaps because forest and ocean sinks are starting to decrease, and greater than expected sea level rise.
Some of the great anger about the United States that I witnessed in Bonn was somewhat muted by the presence of 16 US States and numerous American cities and businesses who had been organized by California governor Jerry Brown and former New York City mayor Michael Bloomberg under the America’s Pledge Campaign. This group which accounted for almost half the US economy had a large presence in Bonn including a large pavilion which showcased what many US sub-national governments and private sector entities were doing to reduce US GHG emissions. One German participant said to me that he had hope that the United States would eventually do the right thing on climate change despite the Trump’s administration indefensible position because of the presence of the defiant US states and local governments. However, he said since these entities only represented about half of the US GHG emissions, the Trump administration’s unwillingness to cooperate with the rest of the world was a major global abomination.
During the last event I went to in Bonn, a UNEP representative discussed the fact that even if every nation fully achieved GHG reductions at levels they committed to, the world was headed toward over a 3 degree C warming in this Century, a level of warming that is extremely dangerous particularly for some parts of the world. He then exhorted the audience to work tirelessly to get every national, state, regional, and local government to set ambitious GHG reduction targets. The situation is ominous he said, we need “all levels of government, that is nations, regions, and local governments, to immediately work toward achieving zero carbon emissions.”
