Climate summit comes at a pivot point

World leaders are making final preparations for the annual UN climate summit which starts in Spain next week. The meeting comes after a year in which global warming has risen rapidly in the public consciousness, with “climate emergency” recently declared as the words of 2019 by Oxford Dictionaries following a massive increase in their usage.

As a result the upcoming summit is as urgent as it is important on the fourth anniversary of the landmark Paris conference. For while there is growing international recognition that climate change is perhaps the biggest challenge facing humanity in the 21st century, much more action is needed. This was underlined only this week with a hard-hitting report by the UN which showed that the world is on track to produce more than twice as much coal, oil and gas as can be burned by 2030 while restricting rise in the global temperature to 1.5 degrees Celsius, the uppermost limit scientists say is necessary to prevent dangerous or so-called “runaway” climate change.

The study compares plans by countries for fossil fuel extraction with the goals of the 2015 Paris agreement, which aimed to keep global heating below 1.5 C.  It found a massive divergence between planned fossil fuel production by 2030 and these targets: Around 120 percent more than that consistent with 1.5 C, and 50 percent more than accords with even a rise in temperature of 2 C.

While the difference between 1.5 and 2 C may seem inconsequential, scientists have warned that it could be hugely significant in terms of exposing potentially hundreds of millions more people to much higher risks of extreme weather, including drought and heatwaves, with the environmental, social and economic consequences that come with this.  And, alarmingly, the UN forecasts that current country pledges to cut carbon emissions are far short of even 2 C warming, with potentially calamitous 3-4 C increases predicted.

In this context, it is clear that world leaders need to ratchet up collective climate ambitions into the 2020s with urgent, unprecedented action.  This requires genuine statesmanship, especially in the context of the Intergovernmental Panel on Climate Change assessment that there may be only around a decade to prevent the worst impacts of “runaway” global warming.

Take the example of the Middle East and North Africa, which the Max Planck Institute for Chemistry forecast last year will see summer temperatures rising twice as fast as the global average. It forecasts that extreme temperatures of 46 C or more will be around five times more likely by 2050 than at the beginning of the millennium. In this context, it is not just hotter temperatures, but also increased dust storms and longer droughts that will greet the region.

In these circumstances, pessimism may yet grow about the future of global efforts to combat climate change. Yet, while the scale of the challenge is huge, and growing, actions can still be taken collectively by governments, businesses and individuals to potentially turn this situation around under the flexible Paris treaty.

While the deal is far from perfect, it has kept the process “alive,” the importance of which cannot be underestimated.

Paris came after many years of painstaking negotiations and, crucially, a new post-Kyoto framework was put in place. The deal agreed to see greenhouse gas emissions peak “as soon as possible,” and achieve a balance between sources and sinks of greenhouse gases in the second half of this century.

In the four years since, critics of the deal — from different parts of the political spectrum — have already sought to diminish its significance. However, the agreement deserves to be defended robustly for as then-US President Barack Obama said in 2015, it may prove to be “the best chance we have to save the planet we have.”

For those who argue that Paris is not ambitious enough, it needs to be remembered that the long-running UN-brokered talks almost collapsed several times before the agreement in 2015, and that this was one of the most complex set of international negotiations ever. While the deal is far from perfect, it has kept the process “alive,” the importance of which cannot be underestimated.

Moreover, the review framework means that countries in future can toughen their response to climate change. So, rather than viewing Paris as the end of the process, it must be seen as an important stepping stone in a longer journey.

What is important now is that the political “window of opportunity” provided by the treaty is leveraged. Four years on from its agreement, this includes the need for implementation as quickly as possible.

Overall, tackling the challenges posed by global warming remains a massively ambitious agenda that will require comprehensive and swift action from governments and corporations if it is to have any prospect of being achieved. While this is uncertain, the fact remains that Paris created a window of opportunity for the 2020s, and what is now needed is political, business and civic leadership to help ensure effective implementation, and holding the public and private sectors to account so that the treaty truly delivers.
