Answers

1. According to the video, by 2050 the Earth has warmed 2 degrees Celsius since the 1800s.
2. In 2050, summer days are said to exceed 40 degrees Celsius in London and 45 degrees Celsius in Delhi.
3. The southwestern United States, southern Africa, and eastern Australia are mentioned as experiencing longer, more frequent, and more severe droughts.
4. Health issues mentioned include heatstroke, dehydration, exhaustion, higher rates of premature and underweight births, asthma, and respiratory diseases.
5. Sea level is projected to rise by „well over a meter” by 2100.
6. The Marshall Islands and Tuvalu are mentioned as becoming uninhabitable due to rising sea levels.
The video states that overall, 250 million people are displaced in this future scenario.
7. Adaptation measures for affluent cities like New York and Shanghai include elevating buildings and roadways, and building ten-meter-tall seawalls along the coasts.
8. Tropical and subtropical crops rarely show up on shelves due to intense heat waves paired with increasing humidity, making it deadly for farmers to work outdoors.
9. The video states that in less than a decade, warming projections have shifted downwards. We’re no longer on track to hit nearly 4 degrees of warming, as previously projected.
10. These answers reflect the information provided in the video transcript about the potential future impacts of climate change.
