A global, three-dimensional computer model of the climate system; GCM's are highly
complex and they represent the effects of such factors as reflective and
absorptive properties of atmospheric water vapor, greenhouse gas
concentrations, clouds, annual and daily solar heating, ocean
temperatures and ice boundaries. The most recent GCM's include global
representations of the atmosphere, oceans, and land surface.
They are often used to model the effects of human induced climate change into the future; but the accuracy of the models are highly dependent upon:
Genetically Modified Organisms (GMOs) are organisms whose genetic materials have been
altered using genetic engineering.
There are concerns that GMOs contribute to environmental concerns such as increased cancer risk, allergens, toxins, and contamination.
A geoexchange system is an electrically powered heating and cooling system for interior spaces. This system utilizes the earth (or a pond or lake) is both a heat source and a heat sink. Components of the system include a heat pump, a hydronic pump, a ground heat exchanger and a distribution subsystem. Most geoexchange systems utilize air ducting for the distribution system and polyethylene piping in the earth for the heat exchanger.Search the Web for GeoExchange System

The average of the sea temperature in the first few meters of the oceans
and the temperature 1.5 m above ground on land surfaces.
Note: This is very subjective, the method of calculation and extrapolation to synthesis temperature for regions where there is scant direct temperature measurement (such as at the Poles), varies a lot.
The GWP is the ratio of the warming caused by a substance to the warming caused by a similar mass of carbon dioxide. Thus, the GWP of CO2 is defined to be 1.0 . CFC-12 has a GWP of 8,500, while CFC-11 has a GWP of 5,000.Search the Web for Global Warming Potential

Gluten Free refers to food or a diet which has a greatly reduced amount of Gluten in it. It may indeed be totally gluten free but it practice this is usually very hard to achieve as gluten is found in so many off the shelf foods and ingredients - often not directly referred to in the labeling.
The exact level at which gluten is harmless is uncertain and controversial. A recent systematic review tentatively concluded that consumption of less than 10 mg of gluten per day is unlikely to cause histological abnormalities, although it noted that few reliable studies had been done.
Also exactly what the label gluten-free actually means on food varies markedly by country.
Gluten Intolerance (or Gluten Sensitivity) is a spectrum of disorders, including coeliac disease and wheat allergy, in which gluten
has an adverse effect on the body. It can be defined as a non-allergic
and non-autoimmune condition in which the consumption of gluten can lead
to symptoms similar to those observed in Coeliac Disease or wheat
allergy (other conditions which fall under the gluten-related disorders
Research as to the exact mechanism in play is still ongoing and how it fits in with other food disorders.
Going green refers to action that can be taken to consciously curb harmful effects on the environment through consumer habits, behavior, and lifestyle.
A government solar rebate is where the government provides a payment or rebate against the cost of installing a solar power system.
This is either in the form of a direct payment or carbon credit multipliers (where the number of carbon credits the system has is multiplied).
Usually you don't get to deal with the rebate directly, the system installer will take care of the paperwork for you and your installation cost will be discounted by the amount of the rebate.
There is some debate over whether the rebate mechanism has 'distorted' the market and made solar seem overly competitive when compared to other methods of generating power.

Green Architecture refers to the process of designing a building to have a reduced environmental impact either by reusing existing materials or using new materials in a lower impact way. Green architecture also focuses on reducing the ongoing energy consumption of the building.
Note: This does not mean than an existing building cannot be made more Green, rather it encompasses making sensible use of what is preexisting in a way that is more Green. Often reusing a building than completely removing it can have a dramatic positive impact on reducing environmental impact over the longer term.
Green building (also known as green construction or sustainable building) is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from siting to design, construction, operation, maintenance, renovation, and final deconstruction.
This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort.

A green-collar worker is a worker who is employed in the environmental sectors of the economy, or in the agricultural sector. Environmental green-collar workers satisfy the demand for green development. Generally, they implement environmentally conscious design, policy, and technology to improve conservation and sustainability. Formal environmental regulations as well as informal social expectations are pushing many firms to seek professionals with expertise with environmental, energy efficiency, and clean renewable energy issues. They often seek to make their output more sustainable, and thus more favorable to public opinion, governmental regulation, and the Earth's ecology.

If a business practices some form of sustainability or takes conscious action to limit its environmental impact (by reducing waste and limiting the consumption of resources for example) then that business is in a position to employ green marketing.
Green marketing is communicating environmental credentials to business partners, clients and consumers within a marketing context. In this way a conscious consumer or business is more likely to have their awareness of that business raised.
Of course green marketing has to be truth based or it turns into a form of green washing if things are exaggerated or untrue. In some cases this exaggeration can be illegal!

A green roof is a conventional roof covered with a layer of vegetation, also known as “living roofs”. Green roofs serve several purposes for a building, such as absorbing rainwater, providing insulation, creating a wildlife habitat and helping to lower urban air temperatures and combat the urban heat island effect. There are two types of green roofs: intensive roofs, which are thicker and can support a wider variety of plants but heavy and require ongoing maintenance, and extensive roofs, which are covered in a light layer of vegetation and are lighter than an intensive green roof.Search the Web for Green Roof

GreenGuard certification for a product indicates it has
been tested to ensure chemical and particle emissions meet
acceptable standards. It uses performance-based standards to define
goods such as building materials, interior furnishings, furniture,
cleaning and maintenance products, electronic equipment and personal
