The direct impact of climate change is not the only reason to be concerned about future fresh water scarcity – a fact highlighted by a recent united nations environment programme report the increasing global population means more demand for agriculture, greater use of water for irrigation and more water pollution. Hearing on climate change and its impact on western water madam chairwoman and members of the subcommittee, my name is terry fulp, and i am the area manager at the boulder canyon operations office at the bureau of reclamation.
The impact assessment combines hydrological models with regional climate change projections to identify key environmental changes, for instance in temperature or precipitation, by the middle of the century (2046-2065) and by the end of the century (2081-2100.
Climate change is altering the water cycle and influencing water quality and availability water professionals need to understand the impacts of climate change on water, epa’s response, and available tools to mitigate and adapt. As climate change warms the atmosphere, altering the hydrologic cycle, changes to the amount, timing, form, and intensity of precipitation will continue other expected changes include the flow of water in watersheds, as well as the quality of aquatic and marine environments.
The relationship between climate change and water doesn't end there the systems used to treat and move public water supplies require large amounts of energy, produced mainly by burning coal, natural gas, oil and other fossil fuels. Impacts from climate change are happening now ecosystems and human communities are currently being affected these impacts extend well beyond just an increase in temperature they are happening in the united states, and across the globe multiple sectors of our our society, spanning across regional boundaries, are being affected.
The impact of climate change on water, sanitation, and diarrheal diseases in latin america and the caribbean (august 2007) water and sanitation play a crucial role in the transmission of diarrheal disease. At global level climate change impacts on the overall water cycle (evaporation and precipitation) and affects availability and demand of water resources changing precipitation or melting snow and ice alter hydrological systems, affecting quantity and quality.
Yet another impact of higher temperatures is the melting of inland glaciers this will increase water supply to rivers and lakes in the short to medium term, but this will cease once these glaciers have melted in the sub-tropics, climate change is likely to lead to reduced rainfall in what are already dry regions. Shared fates and experiences in a community can help it withstand changes to water availability due to climate change, a recent study has found the work paired a dynamic systems model of an.
