Why do people believe global warming is occurring on Earth? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331410836 People believe in Global Warming because of these elements of scientific evidence:
*Global Temperature Rise
*Warming Oceans
*Shrinking Ice Sheets
*Glacial Retreat
*Decreased Snow Cover
*Sea Level Rise 
*Declining Arctic Sea Ice 
*Extreme events
*Ocean Acidification ]]> 2019-02-14 17:15:57 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331410836 2. Why are some people skeptical of global warming? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331411345 Rising sea levels is both a certain and uncertain impact of climate change. Sea levels rise and continuously change through centuries. ]]> 2019-02-14 17:16:43 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331411345 3. Where is the fastest warming of Earth's atmosphere occurring? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331411462 The northern hemisphere. Russia, Alaska, North Pole, Greenland area. ]]> 2019-02-14 17:16:57 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331411462 4. Compare global population numbers with rising carbon dioxide levels. Are they related? Explain. el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331411662 They are related since people exhale CO2. As the population increases, the amount of CO2 in the air increases. ]]> 2019-02-14 17:17:17 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331411662 5. Are increasing levels of carbon dioxide in the atmosphere safe for human existence? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331412518 A very high concentration of CO2 can kill us. CO2 is not the best for our health as too much in the area can cause drowsiness, dizziness, confusion, headache, shortness of breath, reduced hearing, muscular tremor, increased heart rate and blood pressure, and excessive sweating. But plants need CO2 so we can in return grow more food.

Where will they go? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331412949 environmental refugee- people that were forced to flee from their homes due to sudden or gradual alterations in the natural environment related to sea-level rise, extreme weather events and drought and water scarcity. An area that will be evacuated soon is the Maldives because of the rise in sea level. These people will probably flee inland or to higher elevation to avoid another evacuation from their new homes that they have to build. ]]> 2019-02-14 17:19:32 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331412949 7. Let's say after college you return to Lisle permanently for the rest of your life. We live in close proximity to the Great Lakes. In 50 years, would we be fleeing our area or accepting environmental refugees into our area? Explain. el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331413206 Chicagoland will be fine. Compared to the other two gigantic cities on the coast. They believe that Chicago and the mid-west is the safe-haven that people from both coasts will flee towards. As for chicago, they have this giant tunnel that is build to hold lots of water which can help manage any flooding that does occur. ]]> 2019-02-14 17:19:59 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/331413206 8. Does gasoline that most cars need to operate and function contribute to the Earth's greenhouse effect? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333246696 The gasoline that burns from cars contributes to the greenhouse gas effect. (car emissions = bad) ]]> 2019-02-20 16:13:53 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333246696 9. How does an increasing consumption of and demand for meat in a human's diet relate to carbon emissions? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333247369 Meats have the highest carbon footprint of all food. "Food’s carbon footprint, or foodprint, is the greenhouse gas emissions produced by growing, rearing, farming, processing, transporting, storing, cooking and disposing of the food you eat." ]]> 2019-02-20 16:14:50 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333247369 10. How does an increasing consumption of and demand for fish in a human's diet relate to carbon emissions? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333248295 Smaller fish that consume oceanic plants have the smallest carbon footprint. But fish that consumer other fish have a higher carbon footprint. Regardless of what we eat our diet will have a carbon footprint. ]]> 2019-02-20 16:16:17 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333248295 11. Find a graphic of human-influenced carbon dioxide emissions and the atmospheric concentration of carbon dioxide. Do the graphs you found look like hockey sticks? explain. el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333248770 The graphs look like hockey sticks. This is because up until 1900ish very little emissions was released into the atmosphere (hense the flat part). Once 1900ish hit, we started emitting more and more into the atmosphere and the carbon levels skyrocketed with the emissions levels (hense the stick) ]]> 2019-02-20 16:17:03 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333248770 12. What can ice cores tell us about the history of Earth's climate over time? How far back in time can ice cores provide information? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333249414 Ice cores can tell us about: 
* past air temperatures 
*Past greenhouse gasses
*Other gasses
*melt layers
* accumulation rate

The ice cores can date back about 10,000 years]]> 2019-02-20 16:18:13 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333249414 13. How have sea levels fluctuated over the last several thousand years? Is this driven by natural circumstances or is this caused by human influence. In your opinion, why? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333249863 The sea level has been increasing over the last thousand years. Scientists believe that this is caused by human influence "Sea level started rising in the late 1800s, soon after we started burning coal, gas and other fossil fuels for energy." ]]> 2019-02-20 16:18:59 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333249863 14. If the glaciers melt, where does most of that liquid (freshwater) go? (Is ocean water drinkable?) Can ocean water be used to irrigate crops for 7 billion Earthlings? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333250894 Most of the melted glaciers falls into the ocean. Ocean water has to be filtered a ton in order to be drinkable. Since ocean water has salt, it is not good to irrigate massive amounts of crops with it. ]]> 2019-02-20 16:20:50 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333250894 15. What is ocean acidification? How has this influenced our oceans over the last 100 years ? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333251516 Ocean acidification is when carbonic acid is formed in the ocean- this is bad. Ocean acidification has been shown to reduce the ability to allow coral reef to be built. ]]> 2019-02-20 16:21:52 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333251516 16. What are seas surface temperatures (SST)? Think of Goldilocks and the Three Bear... are SSTs too hot, too cold or just right? explain. el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333252602 SSTs are measured five meters below the sea surface. A mooring buoy captures the temperature. SSTs need to be just right so ocean storms do not happen. ]]> 2019-02-20 16:23:42 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333252602 17.

How does carbon dioxide trap infrared radiation on Earth? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333253318 Carbon Dioxide is a greenhouse gas. ]]> 2019-02-20 16:24:53 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333253318 19. Clouds (water vapor) are considered a greenhouse gas. How can cloud coverage both complicate the heating of Earth and also help alleviate the heating of Earth? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333253508 When clouds are covering an area, it traps the heat so the earth becomes hotter. But when clouds are not covering an area, the heat escapes making the temperature decrease.  We see this happen often in the winter. ]]> 2019-02-20 16:25:15 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333253508 20. How do El Nino weather patterns influence climate? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333254364 El Nino weather patterns happen when the index hit 0.5 degrees Celsius warmer or more. In an El Nino weather pattern it is typically 
*Wetter in the southern US and East coast.
*Drier in the Ohio Valley, Great Lakes, Northwest and Northern Rockies. 
*Cooler Desert Southwest, Southern Plains, Northern Gulf Coast 
*Warmer in the Northern tier of states from the Pacific Northwest to the Northern Plains, Great Lakes, and Northeast. ]]> 2019-02-20 16:26:44 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333254364 21. Think of Goldilocks and the three bears again. How would you characterize the weather patterns of the US in the last decade from 2008-2018? Very severe weather patters, very weak weather patterns, or consistently average weather patterns. Consider hurricanes, tornadoes, thunderstorms, flooding events, droughts. support with evidence. el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333254869 I would consider it severe weather patterns. There seem to be more and more hurricanes, tornadoes, thunderstorms, flooding and droughts happening more and more often. ]]> 2019-02-20 16:27:38 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333254869 22. Carbon Dioxide has been accociated with the warming of Earth. You have learned in Biology class that co2 in the atmosphere is taken out of the air by plants and trees through photosynthesis and replaced with breathable oxygen. a. does this statement support global warming deniers? Explain. b. Does this statement support climate science research? Explain. c. Does your answer change when you consider deforestation and increased demand for paper and housing? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333256575 a. yes. CO2 traps heat radiation in the earth and plants not being able to convert CO2 to O2 contributes to global warming. 
b. Yes. refer to question 23 and then question 18.  
c. No. The less trees we have the worse our CO2 levels will get. The more CO2 the more heat that is trapped.

If there is no water for the plants to drink and survive, how can they effectively remove carbon dioxide from the atmosphere? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333258905 Since photosynthesis requires H2O, plants will not be able to effectively remove CO2 from the earth with out water. There are oceanic plants that will be okay so humans will not completely run out of oxygen but the ratio of oxygen to CO2 will be worse. ]]> 2019-02-20 16:35:03 UTC https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333258905 24. How does tree ring growth or lack of growth support or refute climate changes in the last 100 years? el19074 https://padlet.com/lisle202/7ok5tqw9qvxw/wish/333267856 Tree rings are sensitive to climate conditions. "tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry. If the tree has experienced stressful conditions, such as a drought, the tree might hardly grow at all in those years" Since many trees are much older than 100 years, scientists can compare recent growth years to years from the past to either. Lack of growth supports the argument that our climate is changing for the worse.
