1.1 Negative Effects of Climate Change
Here are five negative effects of climate change:
• Increased temperatures: Global temperatures are rising, leading to more frequent
and intense heatwaves.
• Rising sea levels: The melting of glaciers and ice sheets is causing sea levels to rise,
threatening coastal communities and ecosystems.
• Extreme weather events: Climate change contributes to an increase in the frequency
and severity of hurricanes, droughts, floods, and wildfires.
• Disruption of ecosystems: Changing temperatures and weather patterns are altering
habitats, leading to biodiversity loss and the extinction of species.
• Impact on food and water security: Droughts and unpredictable rainfall patterns
affect crop yields and water availability, leading to food shortages and water scarcity.
1.2 Mini-Essay on the Negative Effects of Climate Change
Introduction
• 1.2.1a Climate change: Climate change refers to long-term shifts in temperatures and
weather patterns. While some of these shifts are natural, the current warming trend is
primarily driven by human activities, particularly the burning of fossil fuels, which
releases heat-trapping greenhouse gases into the atmosphere.
• 1.2.1b Climate change education: Climate change education is a multidisciplinary
approach to learning about the causes, impacts, and solutions to climate change. It
aims to equip individuals with the knowledge, skills, values, and attitudes needed to
address this global challenge and promote sustainable development. It's not just about
understanding the science but also about fostering responsible citizenship and action.
Body
• 1.2.2a Effects on the environment: Climate change severely impacts the
environment. Increased global temperatures lead to melting glaciers and ice sheets,
contributing to a rise in sea levels that threaten coastal habitats and freshwater
sources. Extreme weather events, such as intense hurricanes, prolonged droughts,
and severe floods, are becoming more common, devastating ecosystems and
landscapes. These changes also disrupt the delicate balance of ecosystems, forcing
species to migrate or face extinction. For instance, the warming of oceans leads to
coral bleaching, which destroys vital marine habitats. The increase in wildfires, often
a result of hotter, drier conditions, destroys vast forests, releasing more carbon dioxide
and further exacerbating the problem.
• 1.2.2b Effects on human health: The effects of climate change pose significant risks
to human health. Increased heatwaves can lead to heatstroke, dehydration, and
