Our climate has always had a certain degree of flux, as evidenced by year-to-year variations in annual precipitation and temperature. ClimateWizard allows users to see these year-to-year changes over the last 55 years, and to see how they combine into trends. These historical maps are extremely detailed, allowing users to look at patterns across a country or to zoom into the changes within their states and even counties.
These ClimateWizard maps and associated graphs help us visualize, for example, the gradually increasing average precipitation levels in Ohio, and the relatively consistent average temperatures across the state.
A great paradox is expected:
A great paradox is expected:
Annual Rainfall is expected to increase 10-15% annually
However, summers are expected to be significantly hotter and drier (Arkansas Summer)
Rainfall will still largely occur in the Spring and Fall and as a result more torrential rainfall events will occur.
The 100 year flood plain or beyond will become all too apparent.
Water flows at a number of locations in Central OH are already lower than historic levels during the summer months.
The Scioto River in Columbus is reduced to 15 cfs flow until water treatment effluent re-enters the river and increases flow substantially.
The metropolitan population in this area is growing an average of 5% annually.
The result:
Greater likelihood of flooding during the spring and fall (even in areas that havenât flooded in recent history.
More competition for limited water availability during summer (people vs nature & human users vs other human users)

During the night of July 27-28, 2006, a series of thunderstorms drenched northeastern Ohio with up to 11 inches of rain. Flooding forced 600 people to be evacuated, destroyed 100 and damaged 731 homes and businesses, and destroyed 5 bridges â all totaling an estimated $30 million in damages. The frequency of heavy rainstorms like this has increased by more than 25% in the Midwest over the last 50 years, a trend that is projected to continue as temperatures rise. Greater runoff and associated flooding will occur with these more frequent, more intense storms, resulting in greater property damage, more residents at risk, a greater strain on emergency responders, and higher insurance rates.

[DVL Observation: This may be a good launch for discussing the value of wetlands and riparian corridors for absorbing runoff and slowing floodwaters, or other freshwater related strategies that are a priority for the chapter. It could also be a good intro to discussing the movement of development out of floodplains. Of the 81 homes and businesses destroyed in Painesville, the 15-acre Gristmill/Millstone condominium complex was one of the hardest hit, with more than 8â of water inundating the buildings. The City of Painesville has just agreed to convert the complex into a park with trees and other floodplain vegetation. Funding for the conversion will come from the Ohio EPAâs Water Resource and Restoration Sponsor Program, and will be complemented by a $3.5 million low-interest loan from the Ohio EPA to make wastewater treatment plan improvements.]

I'm happy I found this blog! From time to time students want to cognitive the keys of productive literary essays composing. Your first-class knowledge about this good post can become a proper basis for such people. Thanks.
