Discovery: Global Warming Recognized
By: United Nation’s Intergovernmental Panel on Climate Change
Global warming is the increase of average temperature in Earth’s atmosphere occurring since the late 19th century. In 2007 the United Nation’s Intergovernmental Panel on Climate Change released the Fourth Assessment Report acknowledging that global warming is occurring. The report summarized a climate model consisting of a predicted increased global surface temperature of 1.1 to 6.4 degrees Celsius by the 21st century, depending on the release of greenhouse gas emissions. Consequences of global warming have included increase in sea level, broadening of subtropical deserts, and change in precipitation. UNFCCC was formed to propose policy changes to reduce the release of greenhouse gases.
Currently nonprofit organizations such as Architecture 2030 exist to establish a response to this phenomenon by setting goals to reduce climate changing release of greenhouse gases by the Building Sector through the development process of planning designing and construction . In addition, market driven programs such as LEED provide owners with a framework for creating green building designs, construction, and operations. These organizations help lower operating costs and increase asset value, reduce landfill waste, conserve energy and water, reduce harmful greenhouse gas emissions, etc . Because The building sector accounts for almost half of all greenhouse gas emissions in the U.S, it is now considered vital that buildings be made efficiently . . `
