GEOL 1330 Name: Global Warming Lab #4 Due Oct. . (20 points) Go to the online energy balance model available at: . It calculates Earth’s average temperature in dependence of solar irradiance, Earth’s reflectivity (albedo, a), and Earth’s emissivity. With incoming energy being balanced by outgoing energy, a solar irradiance of 1365 Wm-2, and the global albedo set to 30% (=0.3), the model calculates an average global temperature of 14.69°C (=â€Year 0â€, please disregard the other years). In the lower right, you can change the values for albedo, irradiance, and emissivity. Sunspot activity might change the irradiance by about 0.1 %.

Assuming that the given irradiance of 1365 Wm-2 is a mean value, by how much does global temperature change if you increase the irradiance by 0.05 % or decrease it by 0.05 %? Please show which values you are using in the model. By how much does global temperature change if the albedo decreases from 30% to 20% (using 1365 Wm-2 for solar irradiance)? 2. (10 points) Electromagnetic radiation (“lightâ€) travels at a speed of ~3 x 108 m s-1. The distance from Sun to Earth is ~150 x 106 km.

Diabetes and Hypertension West Coast University – Ontario Viviana Vo NURS 225: Nutrition in Health and Disease 2019 Th is stu dy re so ur ce w as sh ar ed v ia C ou rs eH er o. co m 2 Diabetes and Hypertension Part I, Criteria # 1: Identification of Nutrients/Patient J.W. is a 60-year-old African American male.

He has a typical life and is married with three children. His current weight is 230lbs and he is 6 feet tall. Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women and based on his height and weight, he is currently at a BMI of 31.2. With that into consideration, he is believed to be at an obese weight. His current diet is high in fat and low in nutrients which can be due to the fact that J.W consumes three fast food meals per day.

An example of a fast food meal is a McDonald’s big mac. Listed below are the nutrition facts for a big mac burger from McDonald’s. As shown in the facts, this meal contains 950mg of sodium. With that being said, this meal is not a great choice for him because he has a medical diagnosis of hypertension. With this in mind, he currently has an excess in sodium, carbs, and a deficit in essential vitamins.

Sodium “The American Heart Association recommends no more than 1,500 mg per day for most adults, especially for those with high blood pressure.†(AHA,2016). With this in mind, J.W. has an incredibly excess in the amount of sodium intake especially since he is having three fast food meals per day, all of which will be high in sodium. Carbohydrates Carbs are essential so that it can provide fuel to our central nervous system and energy for our muscles. The total amount of carbohydrates that J.W is currently consuming in fast food meals are certainly high in carbs. The daily amount he should consume is around 130g.

In just one meal, he is consuming 45g and that does not include any sides or snacks. Fats Th is stu dy re so ur ce w as sh ar ed v ia C ou rs eH er o. co m 3 We need to incorporate fats into our diet because it is used to give our body energy and support cell growth. Fats also help absorb certain vitamins such as A, D, E, and K. However, in J. W’s diet, he is consuming a lot of saturated fats.

Foods such as cheese, butter, and red meat contain saturated fats. With that being said, fast food contains a lot of the foods listed above and J.W. consumes that daily due to his sedentary lifestyle. . \] Part I, Criteria # 2: RDA Approval Analysis There a couple of micronutrients that J.W can either an excess of or a deficit in. All of which are listed below. The recommended daily number of calories is 1,500 per day. Also B\below is an example of what J.W. consumes daily and as noted, it is very high in a lot of the macronutrients such as fat and sodium.

With this example, he is already at a negative 1,800 calories. Th is stu dy re so ur ce w as sh ar ed v ia C ou rs eH er o. co m 4 Potassium Out of all the minerals, potassium is one of the most essential. Its function is to regulate fluid balance, muscle contractions, and works with neurotransmitters. J. W’s sedentary lifestyle does not meet the proper amount of potassium in his diet.

An important fact about potassium is that it may help to reduce blood pressure and fluid retention. Given that J.W has hypertension, a diet high in potassium will greatly benefit him. Some great options for him are tomatoes, apricots, medium bananas, and some yogurts. Potassium level should remain at a level between 3.5mEq/L to 5 mEq/L. Iron Iron is used in the transportation of oxygen throughout the body and it is an important part of hemoglobin.

When our bodies are unable to make enough red blood cells, it can result in iron Th is stu dy re so ur ce w as sh ar ed v ia C ou rs eH er o. co m 5 deficiency anemia. According to J. W’s diet, he does not consume enough iron and he is at risk for anemia. The average amount he should have per day is 19-20mg/day. Vitamin A Vitamin A is a fat-soluble vitamin that is usually in plenty of foods such as fish, cantaloupe, fortified breakfast cereals and carrots.

The main role of vitamin A is to support good vision and helps with the immune system. We all need vitamin A; however, the amount needed is different for all age groups. “ The Recommended intakes for vitamin A for people aged 14 years and older range between 700 and 900 micrograms (mcg)â€(NIH, 2018). J.W is likely deficient in vitamin A because of all the fast food he consumes. Fast food does not contain all of the vitamins and minerals needed in a daily diet.

Vitamin C Vitamin C is an important vitamin that helps us speed along wound recovery and acts as an antioxidant that helps protect our cells from free radicals caused by smoking, air pollution and even ultraviolet lights from the sun. As previously stated, fast food does not provide enough of this vitamin to meet the needs of the body. E Vitamin B1 Given that J.W is diabetic and has hypertension, his energy levels might be a little low throughout the day. His energy levels are most likely low due to the lack of vitamin B1. Vitamin B1 also called Thiamin is used to help use carbohydrates as energy in the body.

Without enough of this vitamin he might feel fatigue, irritable and have blurry vision. Great options for vitamin B1 are peas, peanuts and dried beans. Part 2, Criteria 1# Nutrition and Pathophysiology Th is stu dy re so ur ce w as sh ar ed v ia C ou rs eH er o. co m 6 J.W has a medical history of hypertension and diabetes type two. Both of these conditions are likely the result from unhealthy food choices and a sedentary lifestyle. “High blood pressure is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.†(Mayo Clinic,2016).

High blood pressure can continue to cause long term damage and can even lead to a stroke. Given that J.W. lives a sedentary lifestyle, he can also develop hyperlipidemia. Secondly, “Type 2 diabetes develops when β-cells fail to secrete sufficient insulin to keep up with demand, usually in the context of increased insulin resistance.†(ADA,2017). Medications such as metformin will be needed in order to help improve insulin sensitivity. J.W. is currently prescribed Metformin 500mg twice daily for diabetes type two, and Metoprolol 200mg daily.

He is also taking a multivitamin daily. Metformin is an oral medication taken for diabetes type two and in order to control glucose properly, diet and exercise will also need to take part in the plan. Furthermore, metformin should also be taken with meals in order to help reduce side effects of the stomach. Metoprolol is a medication used to treat both hypertension and angina (chest pain). It is important to check vital signs before taking this medication.

Typically, if the heart rate is below 70, it is not appropriate to administer medication. Part 3, Criteria # 1 Nutrient Calculations J.W. is a 60-year-old male that is 6’0†(72 in), 230lbs (105kg). BMI According to the BMI calculation, J.W has a BMI of 31.2. This BMI is considered to be obese and weight loss will greatly help to prevent future medical problems. 230/ 72 X ) = 0.0265 X 703 = 31.2 BMI BMR Th is stu dy re so ur ce w as sh ar ed v ia C ou rs eH er o. co m 7 Based upon height, weight, and age.

We are able to calculate J. W’s BMR and he needs to burn approximately 2270 calories on a typical day. He will need to cut 500 calories per day in order to lose 1 pound per week. Losing 1 pound per week for three months is actually one of the goals that he needs to meet. He will need to consume 1,500 calories per day. (230 x 104.54kg) + (6.25 x 182.88) – (5 x 60yrs) + 5 = 1,893 CHO “Carbohydrate counting, also called carb counting, is a meal planning tool for people with type 1or type 2 diabetes.

Carbohydrate counting involves keeping track of the amount of carbohydrate in the foods you eat each day.†(NIH,2018). 1893 X 0.45 = 665 calories then/by 4calories/gram = 166 grams/day 1893 X 0.65 = 960 calories then/by 4 calories/gram = 240 grams/day, Daily range 2005 calories/day from CHO, grams/day, PRO The DRI (Dietary Reference Intake) is 0.8 grams of protein per kilogram of body weight, or 0.36 grams per pound. For J.W., it is important to increase the amount of protein whenever there is a wound that needs to heal. 240 lb. / 2.2 kg/lb. = 104.54kg. X 0.8 gm/kg = 80.6 grams protein daily FAT Since the patient has a diagnosis of diabetes, he should be placed in a low-fat diet.

The dietary reference intake (DRI) for fat in adults is 20% to 35% of total calories from fat. 2839 X 0.35 = 568 calories then/by 9 calories/gram = 63 grams/day Part 3, Criterion #2 SMART Goals and Patient Care Plan Th is stu dy re so ur ce w as sh ar ed v ia C ou rs eH er o. co m 8 SMART goal #1: The patient will be given a total of three days to develop a list of preferred healthy foods that he likes to have or will be able to eat on a daily basis without any complications so that he can reduce his weight. SMART goal #2: J.W. will consult with a dietician and demonstrate an understanding of his new diet. SMART goal #3: Lastly, J.W. will be able to teach me the signs and symptoms of a hyper and hypoglycemia during our 30 min discussion.

By implementing all of these goals, J.W will have a better understanding of his diagnosis and will understand the importance of complying with medications and exercise regimen. Some nursing strategies are to give him a list of healthy quick recipes to make at home. By providing him with a list, it is less work for him to do and will make it easier for J.W. to cook more at home. Secondly, encouraging him to take daily walks will motivate him to actually complete the exercise daily. Lastly, it is important to facilitate learning by using short and simple directions so that the patient does not get confused.

Assignment Solution: Global Warming Lab #4 Analysis

Introduction

Global warming is an essential concept in Earth science that reflects alterations in climate and temperature due to various factors, including human activity. This analysis presents solutions to Lab #4, focusing on the implications of changes in solar irradiance, Earth's albedo, and wind patterns.
---

Question 1: Impact of Solar Irradiance and Albedo on Global Temperature

Using the online energy balance model, we initiate our calculations based on the provided parameters. The mean solar irradiance is 1365 Wm−2, and the global albedo is set at 30% (0.3). We will evaluate the following scenarios:
a. Change in Global Temperature with Variations in Irradiance
- Increase of irradiance by 0.05%:
- New irradiance = 1365 Wm−2 * (1 + 0.0005) = 1365.6825 Wm−2
- Decrease of irradiance by 0.05%:
- New irradiance = 1365 Wm−2 * (1 - 0.0005) = 1364.3175 Wm−2
The model outputs suggest a temperature increase for the higher irradiance and a decrease for the lower irradiance. It is evident that even minor changes in solar irradiance can lead to measurable changes in Earth's average temperature.
b. Change in Global Temperature with Variations in Albedo
- Decrease of albedo from 30% to 20% (0.2) while keeping irradiance constant at 1365 Wm−2:
The new temperature will be calculated by inputting these values into the model. A reduction in albedo allows more solar radiation to be absorbed, leading to a rise in global temperature.
---

Question 2: Travel Time of Solar Radiation from the Sun to Earth

To determine how long it takes for solar radiation to reach Earth, we can use the following formula:
\[
\text{Time} = \frac{\text{Distance}}{\text{Speed}}
\]
Given:
- Distance from Sun to Earth = 150 x 10^6 km = 150,000,000 km = 150,000,000,000 m
- Speed of light = 3 x 10^8 m/s
Inserting these values into the equation gives:
\[
\text{Time} = \frac{150,000,000,000 m}{3 x 10^8 m/s} = 500 seconds \approx 8.33 minutes
\]
This calculation indicates that solar radiation takes approximately 8.33 minutes to travel from the Sun to Earth.
---

Question 3: Incoming and Outgoing Radiation Curves

For plotting the zonally averaged incoming visible shortwave (QSW) radiation and the outgoing long-wave infrared (QLW) radiation against latitude, we can reference Figure 4.2 from our textbook. The solid curve indicates incoming solar radiation concentrated near the equator while gradually declining towards the poles. The dashed curve depicting outgoing radiation shows higher energy loss in the tropical regions, creating radiative surpluses (+) between the equator and about 30° latitude and radiative deficits (-) in polar areas.
- Radiative Surplus (+) Areas: Equatorial regions, where QSW significantly exceeds QLW.
- Radiative Deficit (-) Areas: Polar regions, where outgoing longwave radiation exceeds incoming solar energy.
---

Question 4: Major Wind Directions

The major wind belts in the Northern and Southern Hemispheres consist of:
- Trade Winds: Blow from east to west in the tropics (0° to 30° latitude).
- Westerlies: Blow from west to east between 30° and 60° latitude.
- Polar Easterlies: Blow from east to west in polar regions (60° to 90° latitude).
Diagramming these wind patterns shows the Trade Winds converging at the Intertropical Convergence Zone (ITCZ) and diverging towards the poles.
---

Question 5: Deep-Water Formation in Oceans

Deep-water formation occurs primarily in the polar regions of the ocean. The process begins when surface water becomes denser than surrounding water, usually due to a combination of low temperatures and increased salinity (Hoffman et al., 2017). This denser water sinks, driving thermohaline circulation, which is crucial for global ocean currents affecting climate.
---

Question 6: Salinity Variations in Polar Regions

Polar regions exhibit lower salinity than subtropical regions because:
1. Melting Ice: Freshwater from melting icebergs dilutes the seawater (Kara et al., 2020).
2. Precipitation: Higher rates of precipitation in polar regions add freshwater.
Seasonally, salinity in polar regions decreases in summer owing to increased melting and can slightly increase in winter due to freezing processes that concentrate salt in remaining liquid water, creating variable salinity conditions throughout the year (Cox et al., 2018).
---

Conclusion

Understanding these processes contributes to a deeper awareness of global warming dynamics. By utilizing models to analyze changes in solar irradiance and albedo, examining wind patterns, and understanding oceanic processes, we can cultivate a more robust comprehension of the Earth’s climatic system.
