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.

A Passive House is a house designed to use Passive Solar Design principals to drastically reduce its energy demands by making full use of the energy supplied by the Sun, this thereby reduces ecological footprint of the building.

Passive solar design refers to the use of the sun's energy for the heating and cooling of living spaces. With this approach, the building itself or some element of it takes advantage of natural energy characteristics in materials and air created by exposure to the sun.

Passive systems are simple, have few moving parts, and require minimal maintenance and require no mechanical systems. Often the thermal characteristics of materials are extensively used, often termed as Thermal Mass design.

Passive Solar Energy is the energy captured by a building from the Sun and used to either heat or cool a building.

Passive ventilation is a natural ventilation system that makes use of natural forces, such as wind and thermal buoyancy, to circulate fresh air to and from an indoor space. 

This is the equivalent number of hours per day when solar irradiance averages 1,000 w/m2. For example, six peak sun hours means that the energy received during total daylight hours equals the energy that would have been received had the irradiance for six hours been 1,000 w/m2. A term often used in association with solar panels.

Perfluorocarbon (PFC) is a powerful greenhouse gas emitted during the production of aluminum.

A fluorinated chemical thought to be a carcinogen that is turning up in the bloodstream of humans and animals. PFOA and related perfluorochemicals have been used for decades to make a variety of nonstick and water-repellent products, including Teflon and other nonstick cookware, stain treatments for carpets, waterproof clothing, greaseproof liners of food packaging, and some personal care products.

In 2006, manufacturers reached a voluntary agreement with the U.S. EPA to eliminate almost all use of PFOA by 2015, although the use of other fluorinated chemicals will continue.

Global warming is the name given to the theory that there is increase in the average temperature of the Earth surface air and oceans since the mid-20th century and its projected continuation.

The exact mechanism of warming is not precisely understood, although it is strongly suspected that Greenhouse gases are to blame, as increasing concentrations of such gases help trap heat in the atmosphere and so raise mean temperatures.

Pesticides that do not break down chemically or break down very slowly and remain in the environment after a growing season.

This is the small but not insignificant amount of energy that some of your appliances, such as your television, stereo, answering machine, and microwave oven are using when they are turned off.

Unplugging the devices when you’re not using them or plugging them into a power strip with an on/off switch is often the only way to avoid this waste of power.

Organic compounds that are byproducts of petroleum refining, tanning, and textile, dye, and resin manufacturing. Low concentrations cause taste and odor problems in water; higher concentrations can kill aquatic life and humans.

Used in vinyl products to make them softer and more flexible; also in cosmetics, fragrances, food wraps, and other products. In baby boys, exposure to phthalates can likely increase the risk of birth defects and hormone changes. In men, they likely increase the risk of reproductive problems and hormone changes. The U.S. government regulates industrial discharges of phthalates, but they are unregulated in food products, cosmetics, and consumer and medical products.

A portion of the Earth's surface with a basically common topography and common morphology.

Harmful to plants.

The art of making a product break/fail after a certain amount of time. Not so soon that you blame the manufacturer, but soon enough for you to buy another one and make more profit for them.

A grouping of plant species, or a plant community, that recurs across the landscape. Plant associations are used as indicators of environmental conditions such as temperature, moisture, light, etc.

A cold air mass that forms in a high-latitude source region.

Substance, especially man-made, that pollutes or contaminates an environment.

Reducing the amount of energy, materials, packaging or water in the design, manufacturing or purchasing of products or materials in an effort to increase efficient use of resources, reduce toxicity and eliminate waste.

Polybrominated Diphenyl Ethers (PBDE), is an industrial toxic chemical used as a flame retardant in plastics, furniture and mattresses. This is being progresively banned.

Polyculture is agriculture using multiple crops in the same space, in imitation of the diversity of natural ecosystems, and avoiding large stands of single crops, or monoculture. It includes crop rotation, multi-cropping, intercropping, companion planting, beneficial weeds, and alley cropping.

Waste collected after the consumer has used and disposed of it.

Postmodern Science is a 'branch' of postmodernism.

Postmodernism is "post" because it is denies the existence of any ultimate principles, and it lacks the optimism of there being a scientific, philosophical, or religious truth which will explain everything for everybody - a characterisitic of the so-called "modern" mind. The paradox of the postmodern position is that, in placing all principles under the scrutiny of its skepticism, it must realize that even its own principles are not beyond questioning. As the philospher Richard Tarnas states, postmodernism "cannot on its own principles ultimately justify itself any more than can the various metaphysical overviews against which the postmodern mind has defined itself."

Basically, postmodern science shies away from trying to create a 'unified truth' and rather focuses on the here and now and what is can be 'deduced' from that. The trouble is this leads to science by agreed consensus of observation and trust - rather than the traditional scientific approach of knowledge advancement by experimentation and proving of a hypothesis - i.e. the scientific method. 

The ratio of output power to input power of the inverter.

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 oldest rocks, generally more than 600 million years old.

The approach promoted under the Framework Convention of Climate Change to help achieve stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous interference with the climate system.

Note: In essence this is the 'just in case' approach; the trouble with it is it assumes the cost of doing something is essentially 'free' compared to the future cost of not doing something. Rather the opportunity cost of doing something regardless is not clearly taken into account (i.e. could the money being spent now on inefficient energy sources to combat climate change have been better spent on further energy research that could ultimately lead to no real environmental pollution at all?)  Everything has a cost.

Also the precautionary approach 'weakens' the need for more rigorous scientific principal based research; i.e. you just need to show (and not truthfully prove) a possible outcome to give support to the precautionary approach.

Cap and Trade is a market-based policy tool for protecting human health and the environment.

A cap and trade program first sets an aggressive cap, or maximum limit, on emissions. Sources covered by the program then receive authorizations to emit in the form of emissions allowances, with the total amount of allowances limited by the cap. Each source can design its own compliance strategy to meet the overall reduction requirement, including sale or purchase of allowances, installation of pollution controls, implementation of efficiency measures, among other options. Individual control requirements are not specified under a cap and trade program, but each emissions source must surrender allowances equal to its actual emissions in order to comply. Sources must also completely and accurately measure and report all emissions in a timely manner to guarantee that the overall cap is achieved.

A percentage by which offered prices for recycled products are reduced for purposes of bid evaluation. 

Primary consumers are usually herbivores that feed on plants and fungus, which are in turn Primary Providers. Secondary consumers, on the other hand, are mainly carnivores, and prey on other animals. Omnivores, who feed on both plants and animals, can also be considered a secondary consumer.

That portion of a region's economy devoted to the extraction of basic materials (e.g., mining, lumbering, agriculture).

Variables that are an indirect measure of some combination of climate-related variations back in time. These are used to determine temperature in a time when the thermometer was not yet invented. Examples include tree ring records, characteristics of corals, fraction of melted ice, concentration of salts and acids and the load of pollen trapped in air bubbles.

Note: Given these are indirect measures, the underlying accuracy of such measurements are not equivalent to direct measurement. Also the more indirect the measure (i.e. the more processes between what you are measuring and the temperature) the more inaccurate the representation of the temperature could be. Plus if one is not careful it is possible to 'cherry pick' your proxies to show (either knowingly or not) a pattern of temperatures not representative of the larger whole.

An instrument used for measuring global solar irradiance.

Climategate refers to release/leak/stealing of emails, data and programs related to research into global warming by UEA's Climate Research Unit (CRU); that occurred in 2009 before the Copenhagen Climate Conference (and was therefore probably contributory to its failure). The information obtained was made publicly available for all to see and read through.

It indicates that there good reason to conclude:

• Problems with data retention and archiving;
• Weakly documented data processing both in terms of process and actions undertaken.
• A 'closed ranks' mindset to external criticism and freedom of information
• Close interdependent relationships between a small set of international researchers leading to peer review and career advancement support occurring within the group.
