Impacts of Climate Change

Which of the following are impacts of climate change?

• Sea level rise

• More frequent extreme weather events

• Spread of some infectious insect-borne diseases

• Lengthen the growing season in certain regions

• Greenhouse effect

Global warming can cause the glaciers in Greenland and Antarctica to melt resulting in

• more extreme weather

• a rise in sea level

• an increase in the spread of infectious diseases

Sea level rise is the increase in the mean height of the sea’s surface between high tide and low tide, relative to land.

• True

• False

Check all the statements that explain why sea level rise is a threat:

• Sea level rise will lead to the inundation of low-lying areas such as coastal cities, which constitutes two-thirds of the world’s capital cities. This will cause massive economic losses.

• Sea level rise will lead to the inundation of low-lying small island nation states, which often do not have alternative areas with higher relief to house the remaining population.

• Higher temperatures cause the melting of glaciers and causes water in seas and ocean to expand, thus increasing the sea level.

• Sea level rise will lead to widespread destruction and damage to properties in the densely-populated cities.

2/3 of the world’s largest cities located in coastal areas are at risk when sea level rises.

• True

• False

Which of the following are examples of extreme weather events?

• Heat waves

• Floods

• Famine

• Droughts

• Tropical cyclones/hurricanes

Occurrence of extreme weather events has increased in the last few decades

• True

• False

Which of the following explains why more frequent extreme weather events are occurring?

• Believed to be due to high land and sea surface temperatures

• There are greater amounts of water vapour in the atmosphere

• There are greater latent heat in a warmer atmosphere

• Greater differences in pressures causes wind to move quickly

Which of the following are examples of infectious insect-borne diseases?

• Dengue fever

• Malaria

• Covid-19

• Zika

Why is there rapid spread of infectious insect-borne diseases?

• Increased temperatures around the world made it favourable for insects to thrive

• Increased rainfall allows mosquitoes to grow in numbers in aquatic habitats

• Covid-19

• Regions with moderate temperatures such as Europe and North America are also facing insect-borne diseases now
