Climate change due to human influence is accepted as scientific consensus (see Science of climate change. It is expected have devastating effects on vulnerable communities.
The science of climate change
Climate change skepticsW are a very small and decreasing minority of scientists (and a relatively large number of economists). The relative importance of climate change as opposed to directly addressing poverty is also open to debate.
The positive contribution that climate skeptics can make includes critical analysis of technologies and strategies - this applies when it is considered analysis rather than polemic.
Note that Appropedia is focused on solutions and has only basic and especially relevant information on climate science. See Wikipedia:Climate science as a starting point for climate science information.
What do we do?
The main focus of Appropedia content about climate change is finding ways to reduce the negative impacts of climate change.
While technology is advancing and technologies such as thin film solar photovoltaicsW (e.g. copper indium gallium diselenideW) 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[1])
Another measure is renewable energy, which is more attractive in some locations than others (e.g. solar and biodiesel may be the most cost effective sources of electricity in a sunny isolated location, and solar hot water is perhaps the most cost-effective form of renewable energy in most locations[verification needed]). At this stage the majority of the population in developed countries have access to renewable energy through "green energy" offered by electricity companies (which may or may not be truly "green", to varying degrees). The cost premium for such energy is very modest compared with most people's overall living costs (and modest compared with the money that most people spend on luxuries or entertainment).
Simple living offers various ways of reducing impact as well. To have a serious impact, these need to be actions which appeal to a large number of people, which may be very difficult without changes at the community level. These include promotion of behavior changes, and changing infrastructure in ways that encourage lower-energy behavior. Building of cycleways rather than highways, making communities more walkable, making public transport a more attractive option, and introducing congestion charges (as in London) are supported by many sustainability advocates and organizations.
Ensuring that buyers of houses and other buildings have access to all appropriate information about energy costs, livability (which improves with good passive solar design) and environmental impact, could make a big difference to the building industry, and ensure that sustainability is taken more seriously by more builders.
Note that the cost balance may appear different if externalities are accounted for - e.g. deaths due to vehicles, including emissions; improved health from cycling and walking acting to reduce health costs and improve productivity; and possibly even social cohesion as a result of people mingling on cycle, foot, and public transport, instead of traveling by car.

Notes
- ↑ 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.
