Climate impacts concepts

What is wet-bulb temperature and why is it an important measurement for climate impacts?

• The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed.

• The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only.

• At 0% relative humidity wet-bulb temperature is equal to normal temperature.

• At 100% relative humidity wet-bulb temperature is equal to normal temperature.

What is clean cooking access?

• Access to clean food

• Access to cooking technologies that are clean → not coal or biomass

Which of the following statements are true for wet-bulb-temperature:

• it resembles the temperature felt by humans

• wet-bulb-temperature can only be measured in some regions of the world

• calculation of wet-bulb temperature requires the measurement of sun-light intensity.

• the functioning of human body cooling is closely related to it

What does increased seasonality in climate context mean?

• It means that the difference between dry and wet season is increasing

• It means that the temperature is higher on average

• It means that the difference between dry and wet season is decreasing

• It means that seasonal water availability is getting more unpredictable

Which three dimensions are taken into account when assessing risks of climate change impacts?

• vulnerability

• exposure

• hazards

• likelihood

Extreme poverty defined by the world bank means:

• living below 2 dollars a day

• living below 10 dollars a day

• living below 20 dollars a day

• living below 1 dollar a day

Vulnerable to poverty defined by world bank means:

• living below 2 dollars a day

• living below 10 dollars a day

• living below 20 dollars a day

• living below 1 dollar a day

When is a water resource considered severely stressed?

• 40% of non-renewable surface water is used

• 10% of non-renewable surface water is used

• 20% of non-renewable surface water is used

• 80% of non-renewable surface water is used

Shared socioeconomic pathways:

• are used to assess climate scenarios with integration of the economy

• are classified with regards to climate change mitigation and adaptation challenges

• are generally classified into 6 paths

• are generally classified into 5 paths

The shared socioeconomic pathway number 1 (SSP1) is:

• a sustainable development path

• projects a high share of illiterates in 2100

• projects a urbanization ratio of ~90% in 2100

• projects high inequality in 2100
