Global warming is caused by human-released greenhouse gases like carbon dioxide and methane that trap heat in the atmosphere. As greenhouse gas levels have increased since the 19th century, the average air and ocean temperatures have risen, causing effects like melting ice and snow, rising sea levels, and more severe weather. Global warming is disrupting ecosystems and threatening both human and animal populations by damaging habitats, changing food sources, and spreading diseases. While plants, animals, and humans are attempting to adapt to these changes, reducing pollution from transportation and industry is needed to slow the pace of global warming.

1. GLOBAL WARMING By Andrea EspinosaFrancine GonzalezPaola Gutierrez

2. What is Global Warming?Warming of Earth’s Climate due to human released green house gases. Increase in the temperature of earth’s atmosphere.

3. Green House Gases Carbon Dioxide

4. Methane

5. Water Vapor These gases are released when we drive cars, burn wood or coal, large power plants. Deforestation(cutting down of forests) is also a reason for the greenhouse gases because fewer trees means less carbon dioxide converted to oxygen.

6. WHAT IS CAUSING GLOBAL WARMING Human activities increase in greenhouse gases, such as carbon dioxide means more heat being trapped by the atmosphere, leading to higher temperatures around the globe and potential for global climate change. Carbon Dioxide Increased in the 19th century 30% more Oil, gas, and coal

7. Where is it happening?EARTH!!

8. Evidence for warming.. global average air and ocean temperature

9. Warmer, dry summers

10. Widespread melting of snow and ice

11. Melting Arctic

12. Rising of global average sea levels.

13. Disappearing Islands How is Global Warming affecting Humans?Changing food production and security may cause hungerMore sever and frequent wildfires will threaten more peopleFlooding linked to rising sea levels will displace millions More illness and death resulting from heat wavesWorsening air pollution causes more respiratory and cardiovascular diseaseVector-bore disease infection will rise

14. How is Global warming affecting Animals?Food sourcesPlaces to raise their youngWildlife depends on healthy habitats. They need:The right temperaturesFresh water
