Hans Schellnhuber
Johan Rockström
Gavin Schmidt
What percentage of the world's energy still comes from fossil fuels?
50%
82%
65%
75%
What is the aspirational goal set by the Intergovernmental Panel on Climate Change in 2015?
Reducing emissions by 50%
Staying below 1.5 C
Eliminating fossil fuels
Staying below 2 C
What are the two most promising geoengineering techniques mentioned?
Geothermal energy and electric vehicles
Stratospheric aerosol injection and marine cloud brightening
Wind farms and hydroelectric power
Carbon capture and solar panels
What is the main reason for the opposition to testing geoengineering techniques?
Political disagreements
High costs
Potential side effects
Lack of technology
What year did the first megawatt-scale geothermal plant open in Nevada?
2022
2024
2021
2023
What is the current agreed-upon 'never-exceed' global temperature target?
1 C above pre-industrial levels
2.5 C above pre-industrial levels
1.5 C above pre-industrial levels
2 C above pre-industrial levels
Who told the author that geoengineering would be a 'complete failure of the human enterprise'?
Johan Rockström
Gavin Schmidt
Hans Schellnhuber
Gwynne Dyer
What does 'peak-shaving' refer to in the context of climate change?
Shaving off the tops of mountains to install wind farms
Reducing the peak electricity demand
Cutting down on peak oil usage
Holding the temperature down temporarily
What was the global warming trend over the past 50 years according to a study in Nature in 2022?
0.5 C per half-century
1 C per century
0.2 C per year
0.18 C per decade
How does deforestation contribute to climate change?
Trees release oxygen, which is a greenhouse gas.
It increases the amount of sunlight reflected back into space.
Trees absorb carbon dioxide, a greenhouse gas, and cutting them down reduces this absorption.
Deforestation cools the Earth's surface, disrupting weather patterns.
What is the impact of melting polar ice caps on global sea levels?
Sea levels decrease due to the cold water
Sea levels remain unchanged
Sea levels increase, leading to coastal flooding
The change in sea levels is unpredictable
What role do oceans play in climate change?
Oceans store and distribute solar energy, affecting global climate patterns.
Oceans produce greenhouse gases that contribute to climate change.
Oceans reflect sunlight, significantly cooling the Earth.
Oceans absorb all excess CO2, preventing climate change.
What can be an effect of climate change on weather patterns?
Decreased variability in weather patterns
More predictable weather
Increased frequency and intensity of extreme weather events
A permanent shift to colder weather globally
What is the primary reason for the variation in climate and weather patterns across the Earth?
The uniform distribution of sunlight across the Earth's surface
The varying distance of the Earth from the sun
The uneven heating of the Earth's surface by the sun
The consistent rotation speed of the Earth
What is the main difference between weather and climate?
Weather describes the condition of the atmosphere over a short period, while climate is the average over a long period.
Climate is only concerned with temperature, while weather includes all atmospheric phenomena.
Weather can change, but climate remains constant.
There is no significant difference; the terms are interchangeable.
Which gas is most responsible for the greenhouse effect and climate change?
Oxygen
Nitrogen
Carbon Dioxide
Hydrogen
What is the main cause of climate change according to the majority of scientists?
Natural variations in the Earth's orbit.
Solar flares and sunspots.
Human activities, especially the burning of fossil fuels.
Volcanic eruptions.
What is the main difference between renewable and non-renewable energy sources?
Renewable energy sources can be used over and over again, while non-renewable sources are finite.
Non-renewable energy sources are always cleaner than renewable sources.
Renewable energy sources are more expensive than non-renewable sources.
Non-renewable energy sources can be regenerated within a human lifetime.
The process of converting sunlight directly into electricity is known as:
Biomass conversion
Solar thermal energy
Photovoltaics
Hydroelectric power
What type of energy do wind turbines convert into electrical energy?
Solar
Kinetic
Thermal
Chemical
Which of the following is a renewable energy source?
Coal
Natural gas
Biomass
Petroleum
Which of the following can be used to push a turbine and generate electricity?
steam
water
wind
ALL OF THE ABOVE
