Climate change is a global phenomenon and a challenging reality for thinkers, planners, policymakers and professionals alike. It is a phenomenon that is likely to impact almost every sector of Pakistan’s economy. Today it stands not only as a major environmental issue but also as a multi-dimensional developmental issue. It was in this backdrop that the Planning Commission of Pakistan set up a ‘Task Force on Climate Change’ (TFCC) in October 2008 to provide appropriate guidelines for ensuring security of vital resources of the country such as food, water and energy. The key task assigned to the TFCC was to contribute to the formulation of a climate change policy that would assist the government in pursuing the paramount goal of sustained economic growth by appropriately addressing the challenges posed by the climate change.

Are global temperatures on a warming trend? It is di¢ cult to be certain about trends when there is so much variation in the data and very high correlation from year to year. We investigate the question using statistical time series methods. Our analysis shows that the upward movement over the last 130-160 years is persistent and not explained by the high correlation, so it is best described as a trend. The warming trend becomes steeper after the mid-1970s, but there is no signi…cant evidence for a break in trend in the late 1990s. Viewed from the perspective of 30 or 50 years ago, the temperatures recorded in most of the last decade lie above the con…dence band of forecasts produced by a model that does not allow for a warming trend.

What are the major determinants of green growth? What role can the government play to promote green growth? To address these questions, this paper develops a simple Green Solow model that sheds light on the role of finance and technology in the process of green growth. The empirical section of the article augments this canonical green growth model to include structural variables relating to finance, technological development, trade openness, natural resource exploitations, and areas where the government can play an important role. In addition, the use of the spatially-corrected generalized method moments approach affords us to explore the role of such factors as growth performance of the neighboring countries, domestic learning or determination to achieve its national desired target, and political and economic shocks in the process of green growth. It is hoped that research reported in the paper will stimulate further research in the area.

Scientific research throughout the past decades has demonstrated how climatic changes have important impacts on the livelihoods of people around the world. For most of developing countries their level of structural and social vulnerability, are a dangerous combination and a formula for impacts of higher magnitude. Therefore, climatic phenomenon such as tropical storms, floods and droughts, more often become tragedies in these countries. This paper analyzes the impacts of such phenomenon in the human development of people across the world. Some of the climate change related issues analyzed in this parte are: Droughts and water security, tropical cyclones and storms, rising tides, warming seas, coral bleaching, fish stocks, melting glaciers, heat waves and cold spells and the impact on human health are discussed in this paper along with the differentiated impact on countries in various levels of human development is also discussed.

Paddy soil samples taken from different sites in an old primitive electronic-waste (e-waste) processing region were examined for eco-toxicity and metal contamination. Using the environmental quality standard for soils (China, Grade II) as reference, soil samples of two sites were weakly contaminated with trace metal, but site G was heavily contaminated with Cd (6.37mg kg−1), and weakly contaminated with Cu (256.36mgkg−1) and Zn (209.85mgkg−1). Zn appeared to be strongly bound in the residual fraction (72.24–77.86%), no matter the soil was metal contaminated or not. However, more than 9% Cd and 16% Cu was present in the non-residual fraction in the metal contaminated soils than in the uncontaminated soil, especially for site G and site F. Compared with that of the control soil, the micronucleus rates of site G and site F soil treatments increased by 2.7-fold and 1.7-fold, respectively. Low germination rates were observed in site C (50%) and site G (50%) soil extraction treated rice seeds. The shortest root length (0.2377 cm) was observed in site G soil treated groups, which is only 37.57% of that of the control soil treated groups. All of the micronucleus ratio of Vicia faba root cells, rice germination rate and root length after treatment of soil extraction indicate the eco-toxicity in site F and G soils although the three indexes are different in sensitivity to soil metal contamination.
