Global warming is the current rise in the average temperature of Earth's oceans and atmosphere. The scientific consensus is that global warming is occurring and was initiated by human activities, especially those that increase concentrations of greenhouse gases in the atmosphere, such as deforestation and burning of fossil fuels. This finding is recognized by the national science academies of all the major industrialized countries and is not rejected by any scientific body of national or international standing.
An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice. Other likely effects of the warming include more frequent occurrence of extreme weather events including heatwaves, droughts and heavy rainfall events, species extinctions due to shifting temperature regimes, and changes in agricultural yields. Warming and related changes will vary from region to region around the globe, though the nature of these regional changes is uncertain. In a 4°C world, the limits for human adaptation are likely to be exceeded in many parts of the world, while the limits for adaptation for natural systems would largely be exceeded throughout the world. Hence, the ecosystem services upon which human livelihoods depend would not be preserved.
The Kyoto Protocol is aimed at stabilizing greenhouse gas concentration to prevent a "dangerous anthropogenic interference". As of May 2010, 192 states had ratified the protocol. The only members of the UNFCCC that were asked to sign the treaty but have not yet ratified it are the USA and Afghanistan. Proposed responses to global warming include mitigation to reduce emissions, adaptation to the effects of global warming, and geoengineering to remove greenhouse gases from the atmosphere or reflect incoming solar radiation back to space. According to a recent Gallup poll, people in most countries are more likely to attribute global warming to human activities than to natural causes. The major exception is the U.S., where nearly half the US population attributes global warming to natural causes despite overwhelming scientific opinion to the contrary.
Need Green Houses initiated
Green homes have high economic value, though not require expensive. Indonesia's traditional house has environmentally friendly design as well as cheaper.
This was conveyed Energy Efficiency Design and Architecture Engineer Tri Harso Karyono on Media Meeting with Occupancy with Integrated Green Concept on Mercantile Club Tamara Building, Jalan Sudirman Jakarta, Monday, March 23, 2009.
According to Tri, green housing does not mean expensive. Green residential architecture relies on environmentally friendly causing minimal waste. "The design extreme home Bali and Bedui," he said.
Actually, the green house is not a very difficult and expensive, but most local designers and architects have not much to know, so ignored. In addition to the use of solar power, which is quite expensive, traditional houses adopt housing may be implemented in regular housing.
Tri said, the development of green areas will benefit all parties, not only for homeowners but also for the environment and the government.
He said the government needs to step in green housing provision as set by the government of Scotland. "In Scotland the developer who claims the concept of green, but the reality could not be arrested," he said.
Tri judge, the government is too slow to apply the rules needed some regions. Big cities like Jakarta, which affected the risk of contamination is quite large, green housing needs is essential.
Chairman, Department of Environmental Health of Public Health Faculty on University of Indonesia Budi Haryanto said, environmentally friendly residential areas should be supported and the device that is also environmentally friendly.
Mass transport to reduce energy wastage. Similarly, by expanding the accessibility of pedestrian green housing to reduce the use of transport cause pollution. "But most of that happening now can only be designed residential design with private transport," he said.
Budi said the green housing concept education process must be done from the level of government until the executor (contractor). Because, often the contractor doing the construction of polluting the environment.
Examples of fact, the construction of septic tanks should have good air-tight and usually must be drained in three years. "Contractors are often built of brick septic tank where the water is seeping into the ground. so the time drain up to 7 years. Education to these bad contractors are often loose, "said Budi.
The concept of Energy Efficient Houses
A company in the United States succeeded in developing an energy efficient home. The concept of home is called Enertia Building System (www.enertia.com) can maintain the condition of the home stay warm in winter and stay cool in summer. Both day and night, the air inside the house can stay comfortably without having to spend fuel for heating or electricity for air conditioning.
An air flow and access channel, or Envelope, runs around the building, just inside the walls - creating a miniature biosphere. Here solar heated air circulates, pumping and boosting geothermal energy from beneath the house, storing it in the massive wood walls. Thermal inertia causes the house to "float" between the cycles of night and day, and even between the seasons.
