Welcome everyone to today’s presentation on the risks of climate change and global warming. As we gather here, let’s acknowledge the profound impact these phenomena have on our planet, societies, and future generations.
Slide 2: Overview of Climate Change

Presenter:
To begin, let’s define climate change and global warming. Climate change refers to long-term shifts in temperature and weather patterns, primarily caused by human activities—most notably the burning of fossil fuels, which increases greenhouse gas emissions. Global warming specifically addresses the rise in Earth’s average surface temperature due to these climate changes.
Slide 3: Rising Temperatures

Presenter:
The first major risk is rising temperatures. According to the Intergovernmental Panel on Climate Change (IPCC), global surface temperatures have risen approximately 1.2 degrees Celsius since the late 19th century. Consequences include severe heatwaves, impacting human health and agriculture, and causing heat-related illnesses.
Slide 4: Extreme Weather Events

Presenter:
Next, we must address extreme weather events. Climate change leads to more intense and frequent storms, flooding, and wildfires. For instance, hurricanes are becoming stronger due to warmer ocean temperatures, resulting in devastating impacts on coastal communities.
Slide 5: Sea Level Rise

Presenter:
Another significant risk is sea-level rise. Melting polar ice caps and glaciers are contributing to this phenomenon. The National Oceanic and Atmospheric Administration (NOAA) predicts that sea levels could rise by up to 1.8 meters by 2100, threatening low-lying coastal regions, displacing populations, and causing economic loss.
Slide 6: Biodiversity Loss

Presenter:
Climate change greatly affects biodiversity. Many species are struggling to adapt to rapid changes in their habitats, leading to extinction. It is estimated that around 1 million species are at risk of extinction due to climate change, which disrupts ecosystems and the services they provide to humans.
Slide 7: Food and Water Security

Presenter:
Food and water security are also at risk. Changing precipitation patterns and increased temperatures can result in crop failures and reduced yields. The UN Food and Agriculture Organization warns that climate change could increase hunger and malnutrition across the globe, especially in developing countries.
Slide 8: Public Health Concerns

Presenter:
Lastly, climate change poses significant public health risks. Increased heat can exacerbate respiratory and cardiovascular conditions, while the spread of vector-borne diseases is facilitated by altered climate conditions. Vulnerable populations, including the elderly and low-income groups, are particularly at risk.
Slide 9: Conclusion
Visual Aid: Summary bullet points
Presenter:
In conclusion, the risks of climate change and global warming are extensive and interconnected. Rising temperatures, extreme weather events, sea-level rise, biodiversity loss, food and water insecurity, and public health concerns are just a few of the challenges we face. It is crucial for us to act now to mitigate these risks and safeguard our future.
