Modernagriculture is inextricably linked to declining surface water quality (Verhoeven et al. 2006; Broussard and Turner 2009), creating ecological and economic problems spanning local (Bernot and Dodds 2005) to continental (Diaz and Rosenberg 2008) scales. Agriculture is a major source of reactive nitrogen (N) (Sobota et al. 2013) and interacts with hydrology to control N loading to aquatic ecosystems (McIsaac et al. 2001; Donner and Scavia 2007). How future hydrological changes associated with climate will alter N loading to freshwater ecosystems is an emerging concern that remains largely unexplored. Given the implications for water quality, it is critical to understand how agricultural management and a changing climate will interact in contemporary and future agroecosystems.
Understanding interactions between climate change and agriculture is critical to the continued compatibility of agricultural activity and local municipalities that use adjacent rivers as drinking water sources. The U.S.E.P.A. regulates nitrate in drinking water through standards established in the Safe Drinking Water Act (U.S.C. 1986); nitrate is costly to remove, which creates tension between downstream drinking water users and upstream agricultural activity (Des Moines Water Works 2016a). In the Midwestern U.S., tensions heightened recently when the City of Des Moines (Iowa) Water Works filed a lawsuit against county drainage districts in their supply watershed for contaminating water with nitrate (Des Moines Water Works 2015). In addition to local drinking water concerns, known interactions between climate and agriculture will significantly improve the ability of regional models to predict impacts to more distant downstream ecosystems, such as the Gulf of Mexico, where N loading from the Mississippi River creates extensive coastal hypoxia (Donner and Scavia 2007; Broussard and Turner 2009).
The projected future monthly precipitation data are from the NASA Earth Exchange Downscaled Climate Projections (NEX-DCP30; CMDS 2016). The downscaled products are at a 30 arc second spatial resolution and derived from the from the General Circulation Model runs conducted under the Coupled Model Intercomparison Project Phase 5 (CMIP5) (Taylor et al. 2012). We used the emission scenario 8.5 of Representative Concentration Pathways developed for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). We accessed these data through the NCCS THREDDS data service (NCCS THREDDS 2016).
Current economics are driving agricultural intensification in the U.S. and across the globe (Donner and Kucharik 2008; Secchi et al. 2008). In the Midwestern US, this intensification is interacting with climate change to affect water quality. Unchecked, it is possible that weather whiplash and agricultural activities will combine to form a positive feedback loop that motivates farmers to apply more fertilizer to offset excess losses resulting from wetter springs, a practice that is currently being suggested by local managers (Fernandez 2009). Unfortunately, this potential for amplification of water quality problems occurs at a time when the need to reign in the environmental impacts of excessive fertilizer use is becoming widely recognized (Force 2013). Combined, our observations illustrate a harbinger of a future in which increased climatic variation amplifies negative trends in water quality in a region already grappling with impairments (Paulsen et al. 2006).

While the most common cause of whiplash is front- or rear-impact car accidents, the injury can actually happen anytime, according to Vincent Traynelis, MD, a neurosurgeon at Rush University Medical Center. You can get whiplash from a fall, or from high-impact sports, such as snowboarding, skiing, boxing, football or gymnastics.

Whiplash is an uncomfortable and frustrating injury that frequently occurs in car accidents, particularly when a victim has been rear-ended. The condition may take up to several days to manifest in some cases. Whenever symptoms do appear, visit the doctor straightaway for an evaluation.
Whiplash can occur in any type of accident. It is possible for someone to experience whiplash from the force of a low speed accident, but it is much more likely to happen in a high-speed impact situation. When you are in a car accident, the sudden force can tear and stretch muscles and tendons in your neck. The upper part of the vertebrae in your back are usually the most impacted and affected by a whiplash injury.
The National Center for Biotechnology Information (NCBI) reports that whiplash can happen during low-speed accidents. Regardless of the speed at which an accident takes place, the people inside the car still absorb the force from the crash. Even if you are completely stopped, if someone hits you from behind travelling at a slow speed you can still experience a whiplash injury.
It could take some time before you experience whiplash symptoms after a car accident. It could take only a few hours or up to several days before whiplash symptoms develop. It is ALWAYS important to get medical attention after an accident.
Ideally, you should see a doctor and seek treatment right after the accident occurs. If that is not possible, see a doctor for an evaluation as soon as you possibly can! This will be a key factor in helping you get fair compensation for your accident related injuries. Here are some common symptoms of whiplash to look out for:
Whiplash is not a visible injury, so it can be more difficult to prove. In order to diagnose whiplash injuries, you will want to see a doctor and have a thorough exam. Common symptoms of whiplash can include:
Your doctor will ask you a series of questions and may ask you to perform tasks to determine whether or not you have a whiplash related injury. Here are a few things your doctor will most likely check during an exam:
Treatment will depend on how severe your whiplash injury is. Common forms of treatment include at-home care, over-the-counter medication, prescription medication, physical therapy and specialized pain treatment.
Chiropractic treatment can be effective in helping to alleviate whiplash. Each whiplash injury is unique, so the appropriate treatment will be determined during an exam. It is common for chiropractors to treat whiplash using manipulation and other muscle relaxation and stimulations techniques.
If you have any stiffness or neck pain that will prevent you from turning your head, you should not be driving. Talk with your doctor regarding any questions you have about whether it is safe for you to be driving.
In most cases, neck pain and stiffness from whiplash is the worst on the day right after an injury. It can get worse for up to several days after an accident. Usually this is a short-term injury, but in some cases, there are people who have symptoms for several months and in some cases, permanently.
Limited mobility and constant discomfort can be extremely taxing for whiplash patients. While many cases of whiplash heal relatively quickly, while approximately 10 percent of patients have a long journey ahead of them and suffer long-lasting neck pain, reports WebMD.
Talk with your doctor if you are experiencing ongoing neck pain and are having trouble with your daily activities. It is easy for people to get depressed or experience anxiety when they have had ongoing symptoms due to whiplash. It can take some time to heal from your injuries. Everyone recovers differently, so be sure to keep the lines of communication open with your doctor and try to stay focused on treatment and healing.
The treatments for whiplash can be effective, but they can also be extremely pricey. If you sustained whiplash or any other type of injury in a car accident, you may be able to file a claim for compensation to cover your costs. If you are eligible, you can receive restitution for all your injury-related damages, including:
You may also claim damages related to your pain and suffering. The first step to filing a claim is to speak with a local car accident attorney. A lawyer will be able to determine if you have a viable case and then help you take the necessary steps to secure a settlement.
Whiplash can be a disputed injury as some insurers may argue that your condition is not as severe as you are claiming, so legal representation that specifically handles these types of cases can be very helpful when pursuing a claim.
