Rising atmospheric carbon levels and human actions such as deforestation have caused global climate shifts, driving extreme temperatures, intense rainfall, floods, and droughts. In south-western Nigeria, ecological zones like the Tropical Rainforest and Guinea Savannah are critical for biodiversity and nutrient cycles but remain vulnerable to these variations. An investigation across Ekiti, Ogun, Ondo, Osun, and Oyo states assessed local understanding and consequences of climate variations using surveys, interviews, and geographic information system tools across 371 respondents. Findings revealed high awareness across both ecological zones, reaching 95.45 percent, influenced primarily by formal education, cultural context, and information channels. Reported impacts span environmental degradation, economic difficulties, and consequences for physical health. Addressing these challenges calls for sustained public awareness campaigns alongside the integration of climate change education across all learning levels.
Ecological zones such as tropical rainforests and savannahs are vital for biodiversity and carbon cycles. Measuring regional awareness and impacts helps policymakers and educators identify community needs. Establishing high baseline awareness confirms that communities already observe changes in their environment, economy, and health, demonstrating the need for targeted educational campaigns and structured resilience measures.

The impact of climate change on the Tropical Rainforest and Guinea Savannah vegetation zones is a global and regional concern due to their high biodiversity and role in regulating carbon, water, and nutrient cycles. Recent environmental changes are linked to rising atmospheric carbon levels caused by human activities like deforestation. Evidences of climate change have been seen across the atmosphere, oceans, cryosphere, and biosphere, indicating global warming. These changes include temperature extremes, heavy rain, floods, droughts, storms, and other climate extremes. This study assessed climate change awareness and impacts in the Rainforest and Guinea Savannah zones in southwestern Nigeria, using a mixed-method approach, to determine the level of awareness of climate change impact in the two ecological zones. Primary data were obtained through surveys and interviews of respondents A purposive sampling technique was used with Taro Yamane Formulae (TYF), to determine sample size and a sample of seventy-seven (77) respondents selected from each of the five study States: Ekiti, Ogun, Ondo, Osun, and Oyo. The sampling targeted participants who best represent the population with total of 371 respondents. Climate data were analyzed with GIS tools (ArcGIS Pro), and Fisher’s exact test examined hypotheses. The study revealed that awareness levels are similar across the ecological zones with 95.45%. The level of awareness is created by sources of information, education level, and culture. Climate impacts affect the environment, economy the physical, and health life of the populace. The study recommends public awareness campaigns and integrating climate change education at all levels.
