    Climate Change and Carbon Reduction Initiatives for Sustainable Campus
    (European Journal of Social Sciences, 2009) Kadaruddin Aiyub; Kadir Arifin; Azahan Awang; Jamaluddin Md. Jahi; Shaharuddin Ahmad; Mohd. Talib Latif; Ahmad Fariz Mohamed
    Climate change is a global issue that needs to be tackled by every individual, groups, organization and nations. With our current path of development, climate change seems inevitable. Mitigation measures and adaptation strategies need to be set up just to avoid any further destruction. As IPCC reported that current CO2 level is around 380ppm and will increased to 450ppm under business as usual scenario, stabilization at this point will increased temperature by 2° C. Any increasing in temperature beyond this point will risk human life.This research promote one of mitigating measure, Carbon Reduction Initiatives (CRI) that involved behavior changes on individual and using financial gains as encouragement point.

    Evaluation of long term trends in oxide of nitrogen concentrations in the Klang Valley region, Malaysia
    (Environmental Management Society Malaysia, 2005) Mohamed Elnour Yassen; Jamaluddin Md. Jahi; Shaharuddin Ahmad
    Anthropogenic emissions of NOx account for a large majority of all nitrogen inputs to the environment. The major sources of man-made NOx emissions are high-temperature combustion processes such as those that occur in automobile and power plants. NOx contribute to a wide range of environmental effects directly and when combined with other precursors in acid rain and ozone. NOx react in the air to form ground-level ozone and fine particle pollution, which are associated with adverse health effects. Principally, and for a long time, transport vehicles and industrial emissions are the major sources of the pollutants emitted in the Klang Valley atmosphere. Following the increase of urbanization and industrialization, the amount of traffic has increased in the Klang Valley. Traffic is considered as the major source of NOx in the Klang Valley. Exhaust emissions from the petrol-powered motor vehicles include carbon monoxide, nitrogen oxide, hydrocarbons and particulate matter. A time series analysis of NOx monitoring data from six locations in the Klang Valley Region from 1997 to 2002 is presented. The aim of this study is to evaluate the variations and trends in NOx in the Klang Valley Region for the period 1997-2002.

    Investigation of variations and trends in TSP concentrations in the Klang Valley region, Malaysia
    (Environmental Management Society Malaysia, 2007) Mohamed Elnour Yassen; Jamaluddin Md. Jahi
    Air pollution in the atmosphere by TSP is a problem that has been growing for the last few years due to rapid industrialization, population growth and urbanization in the Klang Valley Region. Suspended particle levels are monitored in ambient air quality network of their potential impact on human health, visibility and climate. The objective of this study is to investigate variations and trends in TSP in the Klang Valley Region and to identify the main factors affecting the variation in TSP concentrations.

    Konsep dan Realiti dalam Pekembangan Habitat Manusia dan Perubahan Iklim
    (Sari, 2010) Jamaluddin Md. Jahi
    Kajian-kajian yang telah dilakukan sehingga kini jelas menunjukkan bahawa perubahan iklim merupakan suatu kejadian yang telah wujud sejak ribuan juta tahun yang lalu dan masih berlaku sehingga ke hari ini. Dalam jangka masa yang begitu panjang kejadian yang berlaku pada masa lampau tidak mungkin disebabkan oleh pembangunan dan perkembangan habitat manusia kerana kewujudan manusia dikatakan tidak melebihi 2.5 juta tahun yang lalu. Makalah ini membicarakan tentang konsep dan realiti perkembangan habitat manusia dan perubahan iklim.
