MEDCs

MEDCs

________ can provide economical and technical support to LEDCs.

Positive

________ and negative feedback mechanisms are associated with climate change and may involve long time lags.

Nuclear power

________ does not emit any greenhouse gases, acidic gases, or any harmful gases related to the deterioration of the environment.

Weather

________ and climate are affected by ocean and atmospheric circulatory systems.

Disadvantages

________: not sustainable to the environment, contributes to climate change and pollution.

flow of heat

Involves reducing the ________ trapping greenhouse gases into the atmosphere, either by reducing these gases, or enhancing them which accumulate and store them.

Fossil fuels

________ contribute to the majority of human energy supply and these vary widely in the impacts of their production and emissions and their use if unexpected to increase tp met global energy demand.

Adaptive capacity

________ varies from place to place and can be dependent on financial and technical resources.

Mitigation

________: attempts to reduce the causes of climate change.

reduction of emissions

Protecting and enhancing carbon sinks through land management ________ from deforestation and forest degradation in developing countries.

Human activities

________ are increasing levels of greenhouse gases in the atmosphere.

Adaptation

________: attempts to manage the impacts of climate change.

Climate

________ describes how the atmosphere behaves over relatively long periods of time whereas weather describes the conditions in the atmosphere over a short period of time.

Greenhouse gases effect

________ is normal and necessary condition for life on earth.

Positive feedback

________: is a feedback that increases initial warming, ________ accelerates temperature rise.

Negative feedback

________: is a process where climate feedback decreases the severity of some initial change, ________ slows down temperature increase.

fertilizers of oceans

Enhancing carbon dioxide absorption by the oceans through ________ to encourage biological pump.

Global climate models

________ are complex and there is a degree of uncertainty regarding the accuracy of their productions.

unit of output

It is the use of technology and substitution to reduce resource inputs an emissions per ________.

Nuclear Power

________ is a low carbon low emission non- renewable resources but is controversial due to radioactive waste and potential scale of any accident.

Fossil fuels

________ are non- renewable, as they can not be naturally retrieved at the same rate in which it is being used up.

Climate

________ is the average weather patterns over many years for a location on earth.

Fossils fuels

________ contribute to the majority of humankinds energy supply, and they differentiate in their impacts of production and their emissions, which is expected to meet global energy demands.

Fossil fuels

________ are stored as solar energy.

Fossil fuels

________ are formed through a natural process, such as in anaerobic decomposition (buried dead animals) which contains energy.

Renewable energy

energy which can be gathered from natural sources which is able to be replenished faster than they are used

Positive feedback

is a feedback that increases initial warming, positive feedback accelerates temperature rise

Negative feedback

is a process where climate feedback decreases the severity of some initial change, negative feedback slows down temperature increase

Global warming potential (GWP)

is a relative measure of how much heat a known mass of a GHG traps a number of years compared to the same mass of carbon dioxide

Mitigation

attempts to reduce the causes of climate change

Adaptation

attempts to manage the impacts of climate change
