Emerging Impacts of Climate Change & Global Warming in Nigeria
Written by: Yuwa Dooyum Joshua
Extreme Weather Events
Nigeria is increasingly experiencing floods, droughts, and severe storms. In 2022 alone, floods displaced over 1.4 million people, destroyed farmlands, and disrupted livelihoods. These events heighten displacement, worsen poverty, and strain infrastructure (National Emergency Management Agency [NEMA], 2022).
Rising Temperatures
2024 was the first year global warming exceeded 1.5°C above pre-industrial levels. In Nigeria, rising temperatures accelerate crop failures, trigger heat-related illnesses, and reduce labor productivity, especially for outdoor workers such as farmers and artisans (World Meteorological Organization [WMO], 2024).
Melting Ice and Rising Seas
Though Nigeria does not have glaciers, it faces the consequences of global sea-level rise. Coastal communities, particularly in Lagos and the Niger Delta, are at risk of flooding, erosion, and saltwater intrusion into freshwater systems, threatening millions of livelihoods (Intergovernmental Panel on Climate Change [IPCC], 2023).
Ecosystem Disruption
Nigeria’s ecosystems face growing stress. Desertification in the north, deforestation, and biodiversity loss disrupt food systems and habitats. Communities dependent on land and forest resources are being forced to adapt or abandon livelihoods (United Nations Convention to Combat Desertification [UNCCD], 2022).
Food and Water Insecurity
Climate shocks in Nigeria reduce agricultural productivity, limit water access, and drive malnutrition and hunger, particularly among children and women. The Sahel and Middle Belt regions are most affected, with herder farmer clashes intensifying as competition over scarce land and water grows (Food and Agriculture Organization [FAO], 2023).
Human Health Impacts
Rising temperatures and worsening air quality have fueled heat-related illnesses and respiratory problems. Climate linked diseases such as malaria, cholera, and Lassa fever spread faster in flood-prone and high-humidity zones, overwhelming health systems (Nigeria Centre for Disease Control [NCDC], 2023).
What’s Driving These Changes?
The increasing concentration of greenhouse gases from burning fossil fuels, deforestation, and unsustainable land use remains the primary cause (IPCC, 2023).
THE URGENCY
Accelerating Rate: Human-induced warming is rising by 0.25°C per decade (WMO, 2024).
Broader Consequences: Even with aggressive mitigation, sea-level rise and ocean heating will persist for centuries (IPCC, 2023).
Vulnerable Areas: Nigeria is among the hardest hit in Africa, where climate pressures fuel insecurity, farmer herder conflicts, and mass displacement.
Practical Solutions for Nigeria
1. Policy & Governance: Integrate climate resilience into national security, agriculture, and urban planning.
2. Community Action: Support farmer cooperatives, women’s groups, and youth-led climate initiatives.
3. Technology & Innovation: Expand renewable energy, digital climate data, and smart irrigation systems.
4. Finance & Partnerships: Mobilize green bonds, climate funds, and public private partnerships for adaptation.
5. Peace building: Link climate adaptation to conflict prevention to reduce farmer herder clashes and displacement.
