The Earth's climate has been changing throughout the history, but the current warming trend of the earth is of significant concern to the world because it is induced by humans at an unprecedented rate in the past 1300 years (IPCC Fourth Assessment Report, 2007). A number of evidences are produced by the scientists to show that the average temperature of earth is rising along with the rising sea-level. According to the CSIRO (2008) report, the global sea level rose to about 17 centimetres (6.7...
By 2030 the world energy needs are predicated to be between 30 and 60% higher than current levels, but of course depending upon the efficiency measures implemented. The International Energy Agency (IEA) estimates that around 4,800 GW of new energy capacity needs to be installed before 2030. This necessitates investments of a mind-boggling US$ 4 trillion. Data indicates 50% of Europe's total energy supplies are imported, much of it from regions considered volatile. Air pollution due to burning...
Efficient use of energy is called "energy efficiency" and the primary objective of energy efficiency is to reduce amount of energy required to provide goods and services. Energy efficiency refers to the ratio between energy output and input (primary energy). Improving energy efficiency both by reducing quantity of energy consumed and by changing processes, offers a powerful tool for achieving sustainable development by reducing the need for investment in energy infrastructure, by cutting fuel...
Research both past and present into solid waste in Nigeria like most developing countries with an absence of adequate solid waste management system has been focused more on adequate collection and disposal options than on the waste generators, storage or even an avenue for waste reduction which aids in reuse and recycling, hence creating major gaps. These gaps are areas that need to address to ensure that there is a sustainable management of solid waste generated to prevent environmental haza...
Climate change is a phenomenon which already happening and represents one of the greatest environmental, social and economic threats facing by the nature and humanity today (WWF). Sugden et al., (2003) state that, Global climate change is one of the difficult environmental issues in our era. It is an undeniable, pervasive, and insidious planetary crisis that affects every aspect in our lives and our future. The climate change because of two factor involve like the climate system (such as in t...
Global warming occurs when the earth suffers a general rise in its average temperatures. This has resulted from emission of greenhouse gases such as carbon dioxide (CO2), methane, water vapor and ozone into the atmosphere, these gases can stay within the atmosphere for very many years, for example carbon dioxide stays within the atmosphere for as long as 50 years to 200 years. These gases trap too much heat and light within the earth's atmosphere which under normal circumstances would be refl...
The world in the last decades has witnessed great advancements in many fields and disciplines. The favor goes first to the industrial revolution in the nineteenth century, and to the advancement in many aspects of technology such as telecommunication technology, transportation, mechanical and electrical. These advancements have created new inventions, and relatively increased the living standards for human been; however, those advancements have some negative impact on the environment. The env...
Under Scottish law, special waste (which is the same as hazardous waste)is any waste that is defined as hazardous by the European Hazardous Waste Directive.1 This report will detail all the steps necessary for the correct disposal of solvent contaminated printers clothes from an Edinburgh printing company. It will describe all the steps from point of origin through to the end disposal , including all the relevant legislation and the real codes and disposal sites that should be used if this wa...
As part of the Government's drive to reduce the waste sent to landfill the Government of the United Kingdom (U.K) have decided that incineration is the answer. This report will outline why it is felt this is the wrong option. As a waste planning authority, under the Town and Country Planning Act 1990, Cornwall County Council (CCC) was legally required to have a 'Waste Local Plan' (WLP). CCC after years of consultation adopted a WLP in December 2002. This was based on a government white paper ...
Climate change is having an adverse effect on the marine environment. Oceans contribute to global weather patterns, sustain intricate food webs and buffer CO2. Sea level rise is evident with climate change but other changes to the marine environment due to climate change are not as well known. This review examines the global thermohaline circulation, how it is measured and the relationship with climate change. Future predictions of the movement of global thermohaline circulation is often cond...
