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.
Capacity factor is a ratio (usually expressed as a percentage) of power actually generated by an installed wind turbine compared to its theoretical maximum power output.
This is important as the available wind varies considerably by location and you want to pick a location that ensures maximum utilization. Although typically the maximum capacity factor achieved in practice is around 30%. This can be compared to the typical capacity factors of 15% for solar and nuclear which ranges in 60 to 100%. Base load thermal power plants (i.e. fire fired) often achieve 70 to 90%.
When capacity factor is combined with cost of production you get the effective cost of power production for a given energy producing technology; i.e. cost divided by capacity factor. This figure you can use as a basis for a ROI (Return on Investment) comparison.

Carbon Fraud is an aspect of global carbon markets.
Basically due to weak certification and validation processes in carbon markets, it is often quite easy to operate a 'fake' carbon offsetting business; i.e. claiming to run an offshore forest preservation scheme generating carbon credits when no such thing exists in reality (i.e. just pocket the money).
Also, due to the difficult nature of assessing exactly how much carbon some scheme or process offsets, you can also get fraud through over estimating the amount of carbon offset.
It is understood in some regions that organized crime has got involved in carbon markets, and that some markets have had to be suspended to investigate systematic fraud.

The theory that policy measures designed to reduce CO2 emissions in one country or region will result in an increase in emissions in another country as carbon intensive firms relocate to areas with less demanding environmental regulations.
For example, it is feared that steel plants and other heavy industries faced with planned carbon pricing regulations in the US may move their operations to countries such as China or India that do not have carbon pricing schemes in an attempt to avoid increased costs.
As a result, carbon emissions could simply "leak" from one country to another, resulting in no net reduction in emissions.
The Kyoto Protocol and the EU Emissions Trading Scheme have both been accused of causing carbon leakage, although there is little solid evidence as yet of firms relocating solely as a result of carbon regulations.
One of the primary drivers for a global agreement to tackle climate change is the hope that an international deal would remove the risk of carbon leakage by establishing comparable carbon regulations for all countries.Search the Web for Carbon Leakage
A Carbon Market is a market created from the trading of carbon emission allowances to encourage or help countries and companies to limit their carbon dioxide (CO2) emissions. This is also known as emissions or carbon trading. Carbon emissions trading is a way of offsetting greenhouse gases produced by polluters.

The sale and purchase of carbon credits or pollution permits through carbon markets.
The practice is designed to help control carbon dioxide emissions by placing a price on a ton of emitted CO2 and providing members of trading schemes with economic incentives to reduce the amount of pollution they produce.
The market is dominated by cap-and-trade schemes, such as the EU's emissions trading scheme, but carbon trading can also refer to the sale of carbon offsets from emission reduction projects.
In theory, carbon trading mechanisms mean that emission reductions are achieved at the lowest possible cost, as businesses will only purchase carbon credits - effectively paying someone else to cut emissions for them - if they can not deliver emission reductions at a lower cost themselves.Search the Web for Carbon Trading

Ceiling insulation is the use of a material to reduce the thermal conductivity (or basic heat transference) via the ceiling and into the space beyond it (namely the roof void). Most often this is achieved through the use of strips of material between the ceiling joists that are often several inches think. The material being able to trap a large amount of still air in relation to its size - this 'trapping' prevents the air transfering heat so prevents the heat loss from below.
Also when the roof space heats up during a hot day it similarly prevents the conduction of the heat into the living space below.

A Climate Change Denier (usually just Denier) is a derogatory term used to describe a Climate Change Skeptic. Usually a sign that a debate on climate change has degraded into name calling and none science based discussion.
The implication is that the 'Denier' is denying the clearly evident facts supporting man made climate change; where as what they do dispute is the link between mans influence on the climate and the changes in the climate being seen, and how much of that change is purely due to natural processes.
Climate Change housing refers to housing that has been designed to operate in a way that minimizes its impact in contributing to climate change through reducing the man made component of climate change.
Note: This does not automatically mean that a house so designed is 'green' or 'eco' over the longer term, rather it is focused on minimizing its man made climate change impact first; which can lead to it been green if done correctly. Basically one does not automatically lead to the other.
Note: Beware of carbon 'get rich quick' schemes; i.e. solar power offsetting, etc as these often only work with costly rebates (which a lot of governments are now pulling out of supplying on mass due to them not being financially sustainable over the longer term).
A Climate Change Skeptic is someone who believes, in the context of Climate Change, that the human influence on the climate has been dramatically overplayed compared to natural processes and other external influences (such as the Sun).
Note: It does not mean they do not believe that the climate changes, rather that the amount of that change due to human activity is over emphasized and too 'precise' given the limited time (a few hundred years) we have had to measure the climate compared to the age of the climatic system (millions of years).
Climate Disruption is essentially a 'rebranding' of AGW caused climate change or global warming to include a larger range of seemingly unusual climatic events to be attributed to mans' influence on the climate system.
Climate Disruption allows events that would otherwise appear to be totally unrelated to global warming, such as excessively cold winters, flooding and storms to be, in the end, attributed to global warming and Co2.
The basic problem with the term Climate Disruption is that it is often 'pinned' on climate events well before any meaningful research or analysis has been done to determine if this is indeed the cause.
Also the fact that we are now better able than any other previous point in history to observe all climatic events means we may be just measuring what passes for a 'normal' frequency and size of climatic events. Also we suspect the large changes in land use and increases in population densities have made what were previously 'normal' climatic events (such as flooding, earthquakes, storms, etc) a lot more damaging in their impact to a population and society. Therefore it is critical that fully analytical research be done on these events independent of the local impact to ascertain if there is indeed any climatic change as the root cause.

A feedback is an enhancement (positive feedback) or a damping (negative feedback) of an initial change, but in this case in a climate system. For example, when less energy reaches the Earth, temperature decreases and the area covered by snow increases. The albedo of the planet decreases, reflecting more energy towards the atmosphere. Consequently less energy is available at the surface, and temperature further decreases. The whole "cycle" from the initial cooling to the further cooling is a feedback, which is a positive feedback in this example.Search the Web for Climatic Feedback Mechanisms

Coeliac disease (spelled celiac
disease in North America) is an autoimmune disorder of the small intestine that
occurs in genetically predisposed people of all
ages from middle infancy onward. Symptoms include chronic diarrhoea, failure to thrive (in children), and fatigue, but these may be absent, and
symptoms in other organ
systems have been described. A growing portion of diagnoses are being made
in asymptomatic persons as a
result of increased screening; the
condition is thought to affect between 1 in 1,750 and 1 in 105 people in the
United States. Coeliac
disease is caused by a reaction to gliadin, a prolamin (gluten protein) found in wheat, and similar proteins found in the crops of the tribe Triticeae (which includes other
common grains such as barley and rye).

Crop rotation is when one grows a series of dissimilar types of crops in rotation, in the same area, in sequential seasons for various benefits such as to avoid the build up of pathogens and pests that often occurs when one species is continuously cropped. Crop rotation also seeks to balance the fertility demands of various crops to avoid excessive depletion of soil nutrients.
A traditional component of crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops. It is one component of polyculture. Crop rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants
Crop rotation is practised by all sizes of farming, from the hobbyist to large farms.

Cross ventilation is when a building is set up to utilize the natural winds that blow across a site to assist with cooling the building.
Simply put the windows are so placed and the internal structure of the property (i.e. placement of doors and open spaces) set up as to allow the easy movement of air from one side of the property to the other when the windows and doors are open; so ventilating the property essentially for free.
This is often a key component of passive solar and thermal mass design. In that during a hot Summer night the windows and doors can be opened to let in the cooler night air, this in turn cools the thermal mass, which the following day helps assist in keeping the property cool.
