Mosquitoes in particular are highly sensitive to temperature. The mosquitoes that can carry malaria (Anopheline spp.) generally do not develop or breed below about 16° C, and the variety that transmits dengue fever (Aedes aegypti) is limited by winter temperatures below 10° C.
Warmer global temperatures will allow an expansion of the geographic range within which both the mosquito and parasite could survive with sufficient abundance for sustained transmission. Model predictions indicate that a 3° C global temperature rise by 2100 could increase the number of annual malaria cases by 50-80 million (not considering factors such as local control measures or health services)
When the dramatic discovery of the ozone hole in 1986 forced the banning of chlorofluorocarbons (CFCs), the refrigeration industry switched to hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). HCFC¹s are also ozone depleting substances but less so than CFCs. Meanwhile, both HCFCs and HFCs are potent greenhouse gasses.
Greenfreeze uses hydrocarbons as the blowing agent for the insulation foam and for the refrigerant. Hydrocarbons are completely ozone friendly, and used in refrigeration have minimal global warming impact.
Hydrocarbon technology is not dependent on patented foaming agents and refrigerants. The operating costs are lower, and the maintenance is easier than with HCFC or HFC technology.
Industrialised nations are responsible for the bulk of greenhouse gas emissions - both today and historically. In the past, economic progress was linked directly to carbon dioxide emissions (via the burning of oil, coal and gas to generate energy). Renewable energy sources change this, but only a small number of nations have begun to implement them in earnest.
Two billion people – one third of the world's population – have no access to electricity for basic needs such as lighting or cooking. Getting people the clean and reliable energy necessary for essential needs such as clean water, health care facilities, heating and lighting is one of the most pressing problems facing humanity today.
Industrialised nations have the capital, resources and expertise to jump-start their renewable energy industries. Obviously, countries with advanced space programs, established higher educational systems and abundant cash for investment are better positioned to implement these new energy technologies then countries still struggling with basic energy needs.
