24. How does tree ring growth or lack of growth support or refute climate changes in the last 100 years? 

# data[].attributes.body
The bigger the ring the more rainfall there was that year, so in the last 100 years if tree rings are smaller it means that there is a drought.

Plants cannot survive without water, so they will not be able to remove carbon dioxide from the atmosphere without it.

# data[].attributes.body
a. Global warming deniers will use this as evidence against climate change because climate change is caused by the massive amounts of CO2 in the air, but if plants absorb CO2, global warming deniers can use this as evidence that it does not exist.
b. No this does not support climate science research, because although it is true it really has nothing to do with climate change.
c. Yes, I forgot about that.

21. Think of Goldilocks and the three bears again. How would you characterize the weather patterns of the United States in the last decade from 2008-2018? Very severe weather patterns, very weak weather patterns, or consistently average weather patterns. Consider hurricanes, tornadoes, thunderstorms, flooding events, and droughts. Support with evidence.

I would characterize the weather patterns in the US during the last decade as very severe due to the natural disasters and shift in climate over short amounts of time. The fires in california, the hurricane season last year, and the polar vortex are all evidence.

Clouds both reflect sunlight, which cools the Earth, and trap heat in the same way as greenhouse gases, thus warming the Earth.

15. What is ocean acidification? How has this influenced our oceans over the last 100 years? 

# data[].attributes.body
Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. As CO2 levels have rose more and more marine animals are dying which effects the marine ecosystems.

If glaciers melt, the liquid flows into the ocean which is not drinkable, ocean water cannot irrigate crops either because saltwater would kill the plants.

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? 

# data[].attributes.body
Over the past several years, sea levels have risen. In my opinion it is caused by human influence. Sea levels rise as the planet gets warmer, and humans have obviously contributed to global warming the most. First, warmer temperatures cause ice on land like glaciers and ice sheets to melt, and the meltwater flows into the ocean to increase sea level. Second, warm water expands and takes up more space than colder water, increasing the volume of water in the sea.

They allow us to go back in time and to sample accumulation, air temperature and air chemistry from another time. Ice core records allow us to generate continuous reconstructions of past climate, going back at least 800,000 years.

# data[].attributes.body
The meat processing factories use a lot of energy which is released into the air as CO2 which contributes to climate change. With an increased demand for meat, more of these factories will be built which will release more CO2 into the air.

6. What's an environmental refugee? What places will people flee from? Where will they go? 

# data[].attributes.body
environmental migrants who were forced to flee "due to sudden or gradual alterations in the natural environment related to at least one of three impacts of climate change: sea-level rise, extreme weather events, and drought and water scarcity." They will flee from places with these issues and will go to countries that will accept them.

4. Compare global population numbers with rising carbon dioxide levels. Are they related? Explain. 

# data[].attributes.body
The population has been rising and so has the carbon dioxide levels. They are related because the more people there are on earth the more demand there will be for resources. For example, meat factories are horrible for the environment because of the amount of CO2 that is released and the production of meat will increase if the population increases. This goes for an resources like houses and buildings.

The evidence is overwhelming. Record-breaking temperatures, humidity, and sea level rise, along with many other indicators, show that the Earth is warming fast, and that all the heat-trapping emissions we release into the atmosphere from burning fossil fuels is changing our climate.
