What does resilience mean?
The capacity of individuals, societies, organizations or environments to recover and resume ‘business as usual’ functions and operations following a hazard event or other system shock.
200
Greenhouse gas.
What is a gas that absorbs and emits radiant energy within the thermal infrared (wavelength) range?
200
Global dimming.
What are ash and dust particles being ejected high into the atmosphere by volcanic emissions, blanketing Earth and reducing incoming insolation?

What are nearly 10 million?
200
Mitigation.
What is any action intended to reduce GHG emissions, such as using less fossil fuel-derived energy, thereby helping to slow down and ultimately stop climate change.
300
Without greenhouse gases, the average temperature of Earth's surface would be this temperature rather than the present average of 15 °C.
What is -18?

What are 6,300 people?
300
Any action designed to protect people from the harmful impacts of climate change but without tackling the underlying problem of rising GHG emissions.
What is adaptation?
400

400
The number of years between each peak in sunspot activity.
What are 11 years?
400
What are positive feedback loops?
What are are knock-on effects in natural systems, which act to accelerate and amplify any changes that have already started to occur.
