What is climate change?
What is climate change?
Changes in Earth's temperature, weather & atmosphere from increased greenhouse effect
Climate effect: global temps
Climate effect: global temps
Rising average global temperatures worldwide
Climate effect: polar ice
Climate effect: polar ice
Melting ice, rising sea levels, loss of polar habitats
Climate effect: seasonal temps
Climate effect: seasonal temps
More extreme variations (hotter summers, colder winters)
Climate effect: weather events
Climate effect: weather events
More frequent & intense hurricanes, storms, heatwaves
Climate effect: natural disasters
Climate effect: natural disasters
Increase in hurricanes, floods, forest fires, droughts
Climate effect: desertification
Climate effect: desertification
Fertile areas becoming deserts from drought & land degradation
4 species threatened by climate habitat loss
4 species threatened by climate habitat loss
