Now is the time for governments to do more
1,200 dead. 1.8 million out of school. 40 million counting the costs of heavy monsoon rains. This year's flooding across India, Nepal and Bangladesh left a trail of devastation that will take years to rectify.
Unabated construction on flood plans, inadequate and clogged drainage systems were undoubtedly a factor. Yet an increase in the risk of extreme rainfall is what we would expect in a warming world, and climate models suggest Asia's summer monsoon will become only more intense and erratic.
It looks little better elsewhere.
We have witnessed hurricanes, droughts, temperature anomalies over 5ºC in the Caribbean and California, in Europe and Africa. While scientists work on attributing specific weather events to climate change, we can say the extreme conditions we witness around the world are a warning from nature. The risks of inaction are growing.
As the latest round of U.N. climate talks gets underway in Bonn, Germany, it's vital world leaders remind themselves of the consequences of inaction. They stressed "we are still in" when President Trump announced his intention to withdraw from the Paris Agreement. Since then, Nicaragua has decided to join. But being part of the agreement is not enough.
In facing down climate change our planet faces a technological, political and economic challenge that can sometimes seem all too much. But by tackling it head-on leaders can reap huge rewards for nature, landscapes, wider humanity and - yes - the global economy.
The 2015 Paris Agreement was the start of a process. It outlined a path along which countries should follow - albeit at varying speeds. When the deal was agreed two years ago we knew it was not - on its own - enough to prevent future extreme weather events. Now is the time for governments to do more.
The national climate plans submitted by governments prior to the 2015 Paris summit are insufficient to meet the goal of limiting the global temperature rise to "well below 2°C". This is why the Paris Agreement established a regular form of reviews to steadily increase national commitments over time.
2018 will see the first review, and it is vital we see States come forward with new and more ambitious targets. It is unrealistic to think that we can always do more later: today's choices determine tomorrow's world, and we are writing this story.
2020 is the year in which we need to see a significant fall in emissions, in order to protect the possibility of staying well below 2C, protect the Sustainable Development Goals, and ensure the decarbonisation of the global economy is smooth and well-managed. It is closer than we think, and policy and investment decisions now will determine where global emissions are by 2020.
We can already see the fruits of the initial round of climate action plans.
National and sub national governments, business leaders and community groups are taking action. In the past year car makers have announced they will use electric motors in all cars as soon as from 2019. Leading banks say they will stop funding coal and shale oil. Shareholders have demanded climate transparency from Exxon. Others have taken further steps towards 100 percent renewables. While some in the US have turned away from the world, many more have emerged to grasp the massive opportunity that lies before us.
Just as the UK and Canada have pledged to lead a new anti-coal push at COP23, we need new leaders to step forward and drive the Paris Agreement onwards.
Climate change is a true test of political leadership. There are few easy answers and many questions. How do we modernise the transportation sector, reducing pollution that is harmful to public health while slashing GHG emissions? How do we transform our agriculture to be more water and soil efficient while reducing the carbon footprint of our food? How do we improve urgently needed access to energy while reducing the carbon intensity of the energy system? How can the possibilities of economic growth in countries that still have so much to develop be strengthened in the short and long term?
Ambition is not blind determination, but rather the commitment to complete the transition combined with the confidence that it can be done. More ambitious policies must match two criteria. They must respond to short and medium term economic expectations and prepare the ground for greenhouse gas emissions neutrality in the second half of this century.
These are sovereign decisions yet leaders should know they are not alone. Every country in the world is now working out how it will quit fossil fuels, as the debate at COP23 illustrates. Every country in the world is developing what is - at heart - a shared vision of the type of society towards which we strive. Each contribution builds mutual trust between stakeholders.
The clock is ticking, the world is waiting. We have under three years and there is no time to waste.
