ABSTRACT
MODELING THE IMPACT OF CLIMATE CHANGE ON WATER RESOURCES
CASE STUDY: ARKANSAS RIVER BASIN IN COLORADO
There is mounting evidence that amount of carbon dioxide is being increased which can lead to changing the global climate drastically during this century. Climate change can have important effect on the water resources and water demand like urban and agriculture uses. The effects of climate change have been explored in the Arkansas River Basin in Colorado which is one of the major rivers in Colorado that provides water for 650,000 people a year and irrigates around 280,600 acres of agriculture areas. The aim of this research is to project precipitation and temperature in smaller temporal and spatial scale by MAGICC/SCENGEN tool and model the impact of climate change on the water resources by water Evaluation and Planning (WEAP) software to provide results for the water managers and policy makers.
Two climate scenarios (A2 and B2) and a 550 ppm policy were used to project future temperature and precipitation in the Arkansas River Basin for the period of 2013 to 2040. Based on the results from the two climate scenarios, a warmer and drier climate is anticipated for the region. Three adaptation scenarios (new irrigation technology scenario, new irrigation technology along with crop change scenario, and new irrigation technology along with reducing crop area scenario) were analyzed to consider their effects to mitigate the negative impact of climate change in the Arkansas River Basin.. This indicates that globe warming is a potentially very serious problem for water management in the Arkansas River Basin. he Greenhouse Effect refers to a naturally occurring phenomenon that is responsible for maintaining a temperature that supports life on earth. However, this is often confused with the Enhanced Greenhouse Effect and Global Warming.
Greenhouse Effect
The Greenhouse Effect occurs because of the trapping of heat reflected from the earth's surface by

    to many island nations around the world. The main cause of these disappearances is “global warming” which is defined as “an increase in the earth's average atmospheric temperature that causes corresponding changes in climate”1. Controversial debates on causes of global warming are on-going. According to the research conducted by Derek Markham, a famous analyst on climate change, the main causes of global warming may be carbon dioxide emissions from burning plants and gasoline, deforestation and increased…

    [pic] Introduction Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades and its projected continuation. In principle, global warming is neutral as to the period or causes, but in both common and scientific usage the term generally refers to recent warming and implies a human influence. Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic…

    The Human Factor of Global Warming The Human Factor of Global Warming Global warming has been a growing concern for many over the last several decades. The effects of global warming are evident and broad, with historical research dating the first global warming crisis back 56 million years ago, better known as the Paleocene-Eocene Thermal Maximum, or PETM (Jardine, 2011). Research from the composition of sediments of fossils shells of marine organisms conclude that carbon dioxide trapped within…

    Global Warming: Are Humans to Blame? Kelly Gaffney October 10, 2011 SCI 207 Instructor Reale In order to understand the issue of global warming (also referred to as climate change), you must first understand what it means and how it happens. Global warming is a result of a process known as the greenhouse effect, in which the light and heat from the sun are trapped in the Earth’s atmosphere by greenhouse gases; which subsequently raises the average temperature on Earth. The greenhouse…

    Impacts of Global Warming in the UK Current data for climate change suggest that global warming is taking place due to the enhanced greenhouse effect. If global temperatures continue to rise it will present a number of challenges in the future. Different countries will experience global warming differently depending on their location and level of development, but even within a country, there will be ‘winners and losers’. For example, in the UK Global Warming is good news for coastal resorts, especially…

    GLOBAL WARMING AND IT’S EFFECTS ON GLACIERS Global Warming The average global temperature has raised more than expected in the past few decades. Many prefer to use the milder term 'climate change' instead of the harsher 'global warming' to describe this change in average global temperature. The main cause of global warming is thought to be the 'greenhouse effect' that is mainly caused by us humans. With an increase in temperature glaciers worldwide are melting faster than the time taken for…
