Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. It can be a change in the average weather or a change in the distribution of weather events around an average (for example, greater or fewer extreme weather events). Climate change may be limited to a specific region, or may occur across the whole Earth.

In recent usage, especially in the context of environmental policy, climate change usually refers to changes in modern climate. It may be qualified as anthropogenic climate change, more generally known as global warming.

The region around the earth in which the earth's magnetic field plays a dominant part in controlling the physical processes that take place.

Clouds that look like pouches hanging from the underside of a cloud.

Programs which by law require consumers to separate trash so that some or all recyclable materials are recovered for recycling rather than going to landfills.

The part of the earth between the crust and the core.

Carbon is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, with 12C and 13C being stable, while 14C is radioactive, decaying with a half-life of about 5730 years. Carbon is one of the few elements known since antiquity. The name "carbon" comes from Latin language carbo, coal.

The average temperature experienced from the combination of all the surface temperatures in a room, i.e walls, floors, ceilings, furniture, and people.

The scale of meteorological phenomena that ranges in size from a few km to about 100 km. It includes local winds, thunderstorms, and tornadoes.

"Artificial trees" are a geo-engineering solution that use amine solutions to capture CO2 out of the atmosphere and sequester it underground.

Also known as "air capture" or "carbon scrubbers", the technology is currently in its formative stages but researchers in the US estimate one tree could take as much as 25 times more CO2 out of the atmosphere each year than a normal tree.

A handful of startups are currently looking to bring the technology to market.

An effective pesticide; used to fumigate soil and many agricultural products. Because it contains bromine, it depletes stratospheric ozone when released to the atmosphere.

The merging of the urbanized areas of separate metropolitan regions; Megalopolis is an example of this process.

This is a small Inverter that mounts on to the back of each solar panel instead of having one large Inverter used by all the panels. While it works better when partial shading is a concern, it can increase the cost of the overall system.

Micro wind turbine is an umbrella term for small scale wind turbines that are typically deployed on or near buildings and used to generate electricity that is transmitted direct to the property.

Micro wind turbines have in the past been criticized for being visually intrusive and generating less energy than expected.

However, suppliers maintain that models can generate up to 100Kw of energy and represent an efficient source of on-site renewable energy as long as they are situated correctly.

A strong localized downdraft less than 4 km wide that occurs beneath severe thunderstorms. A strong downdraft greater than 4 km across is called a down burst.

A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that to the grid act as a single controllable entity. A microgrid can connect and disconnect from the grid to allow it to operate in both grid-connected or island-mode.

The area of the ocean beneath the twilight zone, extending from 3,000 feet (1,000 m) down to the ocean floor, where only about 1 percent of marine life can survive.

Modal is 100% biodegradable and can make a great eco alternative to viscose. It's made from beech trees in Australia and needs few fertilizers or pesticides.

Carbon Footprint refers to the the total greenhouse gas emissions that result from a person, organization, product or service over a given time.

It tends to act as an umbrella term for any attempt to measure greenhouse gas emissions and as a result can refer to simply the emissions that result from a single activity, such as flying; the emissions that result from an organization or building over the course of a year; or the full lifetime emissions of a product or organization, including emissions from the supply chain or disposal of resources.

While carbon footprints colloquially refer to the amount of CO2 emitted, the UK Carbon Trust endorses a wider definition and considers all six of the Kyoto Protocol greenhouse gases - Carbon dioxide, Methane, Nitrous oxide, Hydro fluorocarbons, Perfluorocarbons, and Sulfur hexafluoride - when measuring a carbon footprint.

A coating or discoloration caused by various saprotrophic fungi that develop in a damp atmosphere on the surface of stored food, fabrics, wallpaper, etc.

A change in the genetic material of a living organism, usually in a single gene, which can be passed on to future generations.
