GLOSSARY

climate - the average measurements of temperature, wind, humidity, snow, and rain in a place over the course of years. Climate is like the weather, but over a long time.

climate change - A change in the state or variability of the climate. Climate change is identified by variability in climate properties that persists for a prolonged period and can be identified through statistical tests. Climate change may be caused by natural internal processes or by external forces, such as volcanic eruptions or persistent anthropogenic actions.

climate justice - the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.

disproportionate - uneven or out of balance with something in terms of size, ratio, degree, or extent.

According to the EPA: "the most severe harms from climate change fall disproportionately upon underserved communities who are least able to prepare for, and recover from, heat waves, poor air quality, flooding, and other impacts."

greenhouse effect - The gaseous component of the atmosphere, which may be natural or anthropogenic. Greenhouse gases absorb and emit radiation, which causes the greenhouse effect. The primary greenhouse gases are:

Water vapour (H2O)
Carbon dioxide (CO2)
Nitrous oxide (N2O)
Methane (CH4)
Ozone (O3)

infrastructure - the physical and organizational structures and facilities (e.g. buildings, roads, power supplies) needed for the operation of a society, enterprise, or in the case of the Green Heart Challenge, climate solutions.

renewable - resource is not depleted when used.

renewable resources - resources whose supply is not finite and is not depleted when used, ie: water, wind, or solar power.

non-renewable resources - resources whose supply is finite and is depleted when used, ie: gas, coal, or oil.

sequester (ie: carbon sequestration) - the process of capturing and storing atmospheric carbon dioxide.

weather - the state of the atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness.
