How do you tell people that they must leave their community or drown? This was the gut-wrenching decision I faced five years ago, as president of Liberia, when thousands of families in the largest township of the capital, Monrovia, saw their homes swept out to sea.
Similar devastation stretches across Africa. Mozambique and Zimbabwe are still struggling to recover from Cyclone Idai, the deadly storm that hit in 2019, and Madagascar is on the brink of famine. As weather patterns become more volatile, irregular rain is common, badly affecting crop and livestock yields. For a continent dependent on agriculture — it accounts for around one-fifth of sub-Saharan Africa’s economic output — the effects of climate change are especially ruinous.
None of this is new. Though the continent has contributed the least to emissions — sub-Saharan African countries, excluding South Africa, account for just 0.55 percent of cumulative CO₂ emissions — Africa has been on the front lines of climate change for decades. Yet leaders in the Global North, preferring to indulge in delay and denial, have done little to help.
COP26, the United Nations climate conference in progress in Glasgow, Scotland, is a chance to change that. For the sake of the planet and particularly for Africa, leaders must seize the moral imperative and commit to decisive action.
The first and most important task is to limit global temperature rises to 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, above preindustrial levels. While progress has been made since the Paris Agreement in 2015, the world is still far off track: According to the United Nations Framework Convention on Climate Change, current national targets would result in 2.7 degrees Celsius of warming by the end of the century. For many countries in Africa and across the Global South, that would be truly catastrophic.
All countries — especially the world’s biggest emitters — must come forward with stronger emission-reduction targets that keep 1.5 in view. Crucially, whatever is agreed on in Glasgow needs to be carried out, with heads of government making it a personal political priority. Not only would that be good in itself; it would also build a precious commodity in the fight against climate change: trust.
That’s been in short supply. Over a decade ago, the world’s wealthy countries made a promise to deliver $100 billion a year in climate financing to developing economies. It still hasn’t been met in full. Yet even if the pledge were honored, the figure — though symbolically important — is insufficient. Many African nations are already spending much more than they receive from the international community to mitigate a crisis they did little to create. Leaders must go much further and agree on a target that accurately reflects developing countries’ needs.
Climate finance can do only so much. Indebtedness across the continent is alarmingly high: In Liberia, for example, debt was 54.85 percent of G.D.P. in 2019 — and a staggering 94.5 percent in Zambia. So long as countries are constrained by debt, successfully adapting to climate change is hard to envision. The African Union recently called for rich countries to pass along the pandemic funds allocated to them by the International Monetary Fund to developing countries. Amounting to $100 billion for the continent, this would be a powerful and timely gesture of solidarity.
The sums may appear daunting, but I know from experience that when there is sufficient political will, the international community can act at scale and at speed. At the height of the deadly Ebola outbreak in West Africa in October 2014, when more than 4,000 people had died and infections were rising rapidly, I wrote a letter to the world pleading for more personnel and resources. The response, led by the United Nations, the World Health Organization and the United States, was swift and generous, totaling more than $5 billion. Together, we defeated Ebola.
Climate change poses even more of an existential threat to humanity. In recent months, major economies have been struck by a string of extreme weather events — record rainfall in China, flooding in Germany, wildfires in America. Leaders and citizens of these countries are now experiencing what we in Africa have endured for many years.
The rich world can no longer keep its head in the sand about the consequences of inaction. Now is the time to step up and act — before the flood submerges us all.
