When the sun becomes a threat
It was just 12 p.m. in Accra, but the streets already shimmered under a punishing sun. At the bustling Accra New Town, Hawawu Abdul Karim, a journalist in her mid-30s, wiped sweat from her forehead as she drank from a bottle of water. “Last year, the heat was too much,” she sighed. “I drank a lot of water, but it did not help—it only kept me dehydrated. How do we survive if every year is hotter than the last?” She was compelled to keep bottled water in her fridge at home. Miss Hawawu, who was then working with Voice of America (Hausa) from Ghana, was required to produce quality stories for publication. This meant she had to hunt for stories via public transport under a scorching sun. “Sometimes, I got home so tired, and my room was always so warm that I could not produce stories on time,” she said. Hawa added that she had sleepless nights, drenched in sweat, because of the heat. The situation became even worse when there was a power outage at night or during the day when she was at home. Hawawu’s story is one of millions across Ghana and Africa, where rising heat is fast becoming a silent crisis. According to a new review by the India-based Centre for Science and Environment (CSE), Africa is warming at 0.3°C per decade — nearly 1.5 times faster than the global average. In 2024 alone, the continent recorded an average temperature anomaly of 0.87°C above normal. For Elias, a 36-year-old entrepreneur and farmer in Jirapa, the problem is no longer just the daytime heat. “Sometimes, I feel pain in one side of my neck with off-and-on headaches. Later, the neck pain became so severe that I could not even turn my neck to that side. The heat was really unbearable—imagine sleeping in a room with as many as six people,” he said. CSE’s review shows that night-time land surface temperatures across Africa have risen sharply, with cities like Cairo, Lagos, and Accra recording alarming increases. For families living in informal settlements with poor ventilation, the risk of heat-related illness grows each year. Cities turning into heat traps In Kumasi, Ghana’s “Garden City,” green spaces that once cooled the urban environment are shrinking. Dr Alex Nti-Kani, an environmental economist with Centre for Climate Change & Food Security (CCCFS), explained that rapid urbanisation means people are cutting down trees and paying for every open space.
