The main focus of Appropedia content about climate change is finding Our options are:* Reduce carbon consumption * [[Carbon sequestration]] - prevent consumed carbon from getting into the atmosphere. After combustion, pump it underground or underwater.* Remove carbon dioxide from the atmosphere, e.g. through [[ocean nourishment]], [[biochar]], planting [[trees]].* Reduce the temperature in other ways to (paint roads and roofs white, spray sulfate aerosols into the stratosphere. Note: this does not reduce carbon levels, so [[ocean acidification]] from higher carbon dioxide is still a problem.* [[Climate change mitigation]]: build [[heat tolerant houses]] ([[passive solar]] with suitable [[insulation]]), [[flood control]] barriers)* Grin and bear it: put up with the inconveniences and the negative impacts expected loss of climate changebiodiversity and increases in certain types of [[natural disasters]] (and hope that there will be improvements in other areas).
While The best solution is probably a mix of some of these, as no single solution or even class of solutions appears adequate. The less action is taken, the more we will depend on the "grin and bear it" option. === Technology === The [[bright green]] approach puts its trust in [[technology ]] to give us answers in time, if we just put suitable resources into researching and applying solutions. Technology is advancing and technologies such as [[thin film solar photovoltaics]]{{wp sup|thin film solar photovoltaics}} (e.g. copper indium gallium diselenide{{wp sup|copper indium gallium diselenide}}) offer great hope. However, the rate of progress is uncertain, and as climate change is already happening, action is needed now, without waiting for these new technologies.
The logical place to start is in the area where potential gains are greatest and costs are lowest. This is '''[[energy efficiency]]''', and it offers cost savings in many areas. Thus the most important, pressing actions to be taken can be taken immediately without economic penalty, with suitable planning. Financial planning is an important aspect of this, as investment now may be required to gain long term benefits; it may be important to have programs such as [[light bulb]] exchanges or loans for energy efficiency measures (perhaps paid off through electricity bills<ref> If the energy company benefits from people using more energy, there may be a conflict of interest, so different reward models need to be explored; when the energy company is a government-owned corporation, this may give more flexibility to apply a different model in order to encourage uptake. (See [[Incentives for sustainability]] and [[Incentives to pollute]].</ref>)
