Warmest decade on record leaves trail of misery across Africa
These trends have consequences. The apocalypse is not in the future – it is unfolding now, and history has a long memory.
For decades, there have been warnings that Africa, the world's poorest continent, was the most vulnerable to climate change caused mostly by the burning of fossil fuels up north.
Those forecasts are now a grim reality, a point starkly underscored in the World Meteorological Organization's (WMO's) just released State of the Climate in Africa 2024 report.
The past decade has been the warmest on record globally and Africa has been no exception, with a trail of misery from drought to deluge left in its wake.
'Extreme weather and climate change impacts are hitting every single aspect of socioeconomic development in Africa and exacerbating hunger, insecurity and displacement,' the WMO said.
'The year 2024 was the warmest or second-warmest year, depending on the dataset … Sea-surface temperatures around the continent were at record levels, with particularly rapid warming in the Atlantic Ocean and the Mediterranean Sea. Marine heatwaves impacted the biggest area since measurements started in 1993.'
The sea-surface temperature spike was from January to April and covered an area of nearly 30 million square kilometres. This state of affairs makes tropical storms more intense and devastating.
'For the first time in the satellite era, two tropical cyclones, Hidaya and Ialy, developed in May and moved over the far north-western part of the basin near Tanzania and Kenya over a region rarely frequented by mature tropical systems,' the WMO said.
Surging sea-surface temperatures will also have consequences for marine life, coral reefs, commercial and subsistence fisheries and eco-tourism industries, which are vital to coastal African economies.
This correspondent observed coral bleaching while scuba diving on reefs at Sodwana in northern KZN in March – the first time I had seen that blight in the more than 25 years I have been diving there. If you spend time outdoors, you can't help but notice this stuff.
Subsistence African farmers who rely on rain-fed agriculture are certainly taking note, with last year's scorching El Niño event a case in point.
'The aggregate cereal yields in southern Africa were 16% below the five-year average – and in the case of Zambia and Zimbabwe, 43% and 50%, respectively,' the WMO said.
Then there was the ripple effect on the wider regional economy from dam levels. Water literally evaporated under a blazing sky.
'Low water levels and low hydropower output from Lake Kariba, Africa's largest man-made reservoir, caused prolonged power outages and economic disruption,' the WMO said.
Elsewhere on the continent, the problem was too much rain. Severe floods washed over Kenya, Tanzania and Burundi from March to May last year, killing hundreds of people and directly impacting 700,000. This was followed by below-average rain from October to December, raising concerns about food security.
West Africa endured floods that affected more than four million people, with hundreds of thousands displaced by the drenching.
The cycle is truly becoming increasingly vicious – floods followed by drought or vice versa – the signature events of extreme weather being inflicted on populations that are least equipped to deal with disasters that are biblical in scale.
What this means for you
These trends could exacerbate already existing water shortages in your hood and will push up the prices of many things grown in Africa that you take for granted – coffee, cocoa and vanilla, among other products. And depending on where you live, you will find your home at increasing risk of being hit by floods or scorched by wildfires.
However, the WMO report is not just a litany of woe.
'Many countries in Africa are embracing digital transformation to improve weather forecasts and early warnings and this has been identified as a regional priority. Artificial intelligence brings new potential to strengthen service delivery,' it notes.
The bottom line here is that Africa is getting whacked by climate change mostly linked to global greenhouse gas emissions despite only accounting for around 4% of such emissions – and the biggest emitters on the continent by a country mile are South African, namely Eskom and Sasol.
These, it must be said, are well-known facts among those who keep track of such trends.
But these trends have consequences. And at this rate, things will only get worse before they hopefully get better. The apocalypse is not in the future – it is unfolding in the present, and history has a long memory. DM

Groundbreaking study finds new genes in black women causing breast cancer
Black South African women have been found to have two new genes that make them susceptible to breast cancer. Research done by the Sydney Brenner Institute for Molecular Bioscience (SBIMB) at the Witwatersrand University found genetic factors that contribute to about 30% of breast cancer (BC) cases in South Africa. 'These genes have not been associated with the disease before, which is an important advance in understanding breast cancer risk and biology in women of African ancestry,' said Dr Mahtaab Hayat, a lead author of the study. The two new genetic variants were identified in black South African women with breast cancer enrolled in the Johannesburg Cancer Study, compared to women without cancer in the Africa Wits-INDEPTH Partnership for Genomic Research (AWI-Gen) study. Breast cancer is the second-most common cancer in South Africa and the most common cancer in women globally, with genetic factors contributing to about 30% of cases. 'Our study makes a compelling case for investing in genomic research rooted in African contexts,' said Hayat. All participants were from the Soweto region, with 2,485 population cases and 1,101 control cases. The South African BC cases and controls were well-matched and clustered, while the non-South African samples and West African populations were distinct from South African populations. The Genome-Wide Association study (Gwas), which is the first to focus on black women on the continent, was published in the journal Nature Communications. It brings to the fore the importance of deepening knowledge about the genetic basis of the disease. In the past, most breast cancer genetics research has focused on European and Asian populations, with studies of African ancestry limited primarily to African-American women, who largely descend from West African populations. A tool that estimates lifetime cancer risk based on DNA, the polygenic risk score (PRS), performed poorly in distinguishing South African women with breast cancer from those without. Dr Jean-Tristan Brandenburg, also in the SBIMB and a lead author, said this was a result of the mechanism not being tailored for the black population. 'This is because most PRSs were developed in European populations, and their inaccuracy in African populations highlights the urgent need for ancestry-specific tools in cancer risk prediction,' Brandenburg said. African populations have more genetic variation than any other population in the world, but they have been significantly underrepresented in genomic research. This means that the global understanding of disease risk and the tools and treatment developed from it are limited. 'The study reveals that more people can benefit from genetic discoveries. It proves that new risk factors are still out there, waiting to be found,' says Hayat.

SA is in the forefront of saving rhinos from poaching
Our scientists and game rangers have pioneered the technique of dehorning rhinos to make them less attractive targets for poachers. Side profile of a rhinoceros that has been dehorned to prevent poaching. Picture: iStock While it is commendable that Kenyan efforts to conserve rhino are gaining momentum, we need to disabuse Dr Dominic Mijele from the Kenya Wildlife Service that his country is 'number one in the world' when it comes to translocating rhinos. No, doc. You need to look further south to find the real experts: South Africa, after all, started the concept with the iconic 'Operation Rhino' in the 1960s, which saw around 4 000 rhino relocated from reserves in KwaZulu-Natal to other African countries where they were threatened with extinction because of hunting. Now, as worldwide poaching and the demand for rhino horn ratchets up, South Africa is still in the forefront of the fight to save these iconic animals. ALSO READ: Rhino whisperer fights poaching with drone campaign Our scientists and game rangers have pioneered the technique of dehorning rhinos to make them less attractive targets for poachers. A seven-year study in one of our major conservation areas has shown that dehorning resulting in a nearly 80% reduction in the poaching of the animals. It was also scientists from Wits University's radiation and health physics unit who came up with the idea of injecting radioactive material into live rhino horns to make them easier to detect at borders. Sounds like world-leading to us… NOW READ: 'Relentless threat to wildlife': Here's how many rhinos were poached in SA in 2025 so far

UFS inaugurates new vice-chancellor and principal
Professor Hester Klopper was officially inaugurated as the 15th vice-chancellor and principal of the University of the Free State (UFS) and is the first woman to lead the university in its 121-year history, in a ceremony at its Bloemfontein campus on Monday. She was appointed to this position on February 1. In her inaugural address, titled 'Walking Together with Purpose: Unlocking Excellence to Lead Change', Klopper outlined her vision to transform UFS into a research-led powerhouse that harnesses artificial intelligence while preserving human connection and African identity. Klopper challenged the higher education sector to confront an uncomfortable reality about the pace of technological change vs educational transformation. 'Artificial intelligence capabilities are advancing exponentially, doubling in power every few months. However, our educational systems remain fundamentally unchanged from their industrial-era origins. 'We are preparing students for a world that is transforming faster than we can imagine, using methods designed for a world that no longer exists,' she said. Klopper emphasised that it was essential for UFS to find its place and purpose in confronting the challenges faced by the higher education sector, and not merely emulate what other institutions were doing. 'The question before us is not whether we will adapt — it is whether we will step up and lead this transformation or be swept aside by it,' she said. Klopper shared her vision of UFS as 'a true entrepreneurial knowledge ecosystem, thriving on the creative synergy produced when our best academic minds work together across our three campuses, allowing us to be the very best we can be'. She emphasised that preparing students for the world of work will focus on 'their ability to think creatively, to empathise deeply, to ask the right questions, to challenge assumptions, and to work collaboratively with both humans and artificial intelligence'.
