PARIS – A WASTE OF TIME OR A WAY FORWARD? Research has indicated that a warming climate, caused by net greenhouse gas (ghg) emissions is contributing to changes in environment, suggesting that a large average temperature increase could produce irreversible environmental impacts. At the twenty first Conference of the Parties (COP21), 195 international Governments made the first formal universal collaboration, which aims to end what has been dubbed ‘the fossil fuel (Goldenberg & Neslen, 2016). It focuses

Cap and trade is a system aimed at diminishing the rate at which carbon is emitted into the atmosphere by creating an economic system based on meeting a certain minimal threshold or paying low-emitting companies for the right to emit in their place. For example, if company A only emits half of the emissions cap, that company can sell (or trade) the remaining credits to company B, should company B choose to emit one-and-a-half times the cap. A main objection to the cap and trade system is that it

The majority of people across all academics accept global warming as a phenomenon. Furthermore, greenhouse gases, including carbon emissions, are established to be one of the main drivers of global warming. If allowed to continue, global warming will damage our natural environment as well as our wellbeing. Decreasing carbon emissions is a necessity in order to continue the growth and development of our society. In the past few years, different methods have been studied in order to prevent carbon

Due to mass consumption and pollution, the amount of carbon dioxide released into the atmosphere by Chinese cities have increased dramatically in the last few decade. Currently half of China's cities cannot meet the air quality standards, and one-third of its land is affected by acid rain (Zhang, 2007). In order to protect its people and nature from dangerous environmental threats, sustainable development of China's growing cities must become a top priority, and a key resolution is making them low

Transmission Control Protocol/Internet Protocol, which is the protocol of the Internet. In a private network, TCP/IP can be used as a communications protocol; the TCP/IP can either be an intranet or extranet. A computer is provided with a copy of the TCP/IP program when it is set up with direct access to the Internet. (“What Is TCP/IP”) TCP/IP is a two-layer program. The higher

What IPv4 provides in the header is IP checksum which does error detection but not correction. Still, doing error detection would cause delay on network. That’s why in Internet Protocol version 6 this checksum is abandoned. Since now, the dominator of internet protocol is IPv4, although the spread of the newest version 6 is happening 7 worldwide. Picture below shows how IP packets are field: Fig 2: IPv4 address with total 32 bits. 10 The figure number 3 shows how IPv4

that will include store and forward switching, cut through switching, fragment free switching, and V-Lan. This paper will also cover routing concepts, along with some comparisons including routed vs. routing protocols, Classful vs. classless protocols, and distance vector vs. link state protocols. Switching The definition of a switch or network switch is a small device that joins multiple computers together, working on layer two of the OSI, to form a local

The World’s Reaction to the Implementation of the Kyoto Protocol In this day and age, it has become very easy to take advantage of the seemingly never ending natural resources, and current amenities which our society and scientific endeavors have made possible. However, what many fail to realize, is that on a daily basis, our luxuries are emitting Greenhouse gases into the world, and using up precious resources. While the exact date of when these will truly cause drastic results in our

decrease the emissions of these and other harmful materials, both in product development and production, as well as in product functioning itself. One of the measures instituted to reduce destructive emissions was the 1987 Montreal Protocol. This international document provided guidelines for the reduction of ozone-damaging chemicals on a timeline that would be helpful for ozone repair. It seems as though the reductions that have already taken place have had beneficial effects. The
