Effects of Climate Change
Storyboard Tekst
- Human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil and gas), which produces heat-trapping gases. As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change.
- Rising seas or flooding compromises drinking water, human waste water treatment and storm water disposal that, in turn, results in increased risk of waterborne diseases caused by pathogens such as bacteria, viruses and protozoa.
- Warmer air holds more water and greater or rising temperatures cause higher surface evaporation that in turn increases the number and severity of rain events, now termed rain bombs, resulting storm surge and the intensity, frequency and duration of hurricanes.
- Higher temperatures cause heat exhaustion, heatstroke, hyperthermia and dehydration that in extreme cases can lead to death. Furthermore, it can worsen pre-existing conditions such as kidney and diabetes-related conditions.
- Climate change is endangering polar bear survival in the wild. Since climate change is lengthening the ice-free periods, the polar bears are stranded on land and away from their normal diet of seal meat during the summer, resulting in less fat build up for the winter.
- If we don't act fast enough. Polar bears might go extinct. Help fight climate change!
