First, you MUST login to padlet - click "log in" and then "log in with google"

One person in your group should make their own copy and then share their screen so your group can work on it together.

Click "remake" in the top right hand corner to make your own copy.

MAKE SURE YOU CHECK BOTH "COPY DESIGN" AND "COPY POSTS"!!

Once you have made your copy of the padlet, click the "share" link in the top right corner and click the pink "change privacy" link. Scroll down to "visitor permissions", and click the blue button to change the setting to "can edit". Now, multiple team members can work on it at once!

Copy the link and share it in the chat so your team can work can split up the graphs between yourselves to analyze.

Then you may delete this post.

"CO ₂ measurements are inaccurate. The CO ₂ measurements used as evidence are taken at the top of Mount Mauna Loa Volcano in Hawaii – which doesn’t seem the best place to be measuring CO ₂!"

Is the hypothesis true or false? False
Explain your answer, using the graph as evidence: The lines are almost matched up exactly

# data[].attributes.body
"The sun is getting hotter. Over the past few hundred years, there has been an increase in the numbers of sunspots and therefore solar irradiance, which directly correlations with global warming.”

Is the hypothesis true or false? False
Explain your answer, using the graph as evidence: The two lines in the graph don't match up.

"Most scientists disagree. 31,000 scientists signed a petition, stating that there is no convincing scientific evidence human’s are causing global warming.”

Is the hypothesis true or false? False
Explain your answer, using the graph as evidence: On the graph, we can see that climate scientists think that humans help cause global warming.

# data[].attributes.body
"The scientific models used to predict climate change are unreliable. Models created in the 70s have not accurately predicted temperature so far, so why would they be able to predict the future?"

Is the hypothesis true or false? False
Explain your answer, using the graph as evidence: They didn't have the right technology in the 70s.

# data[].attributes.body
"CO ₂ has nothing to do with global warming. Changes in CO ₂ do not match up with changes in temperature on earth."

Is the hypothesis true or false? False
Explain your answer, using the graph as evidence: The lines are pretty much the same so they relate.

# data[].attributes.body
"The earth hasn’t warmed in the last 100 years. In fact, global warming has stopped and a cooling period is beginning.”
Is the hypothesis true or false? False
Explain your answer, using the graph as evidence: The line keeps going up and it is linear.

# data[].attributes.body
“The CO ₂ changes are normal! Levels of CO ₂ have changed drastically throughout history based on many different factors - the current high levels of CO ₂ just follow these natural patterns.”

Is the hypothesis true or false? True
Explain your answer, using the graph as evidence: The graph goes up and down like the video said.

# data[].attributes.body
"CO ₂ is increasing naturally. There are many natural sources of CO ₂, including plant and animal respiration and volcanic eruptions. The human causes are very small compared with the natural causes"

Is the hypothesis true or false? False
Explain your answer, using the graph as evidence: The human bar is the largest, which means they contribute to global warming the most.

# data[].attributes.body
“Global warming is caused by Volcanic activity. It’s outside of our human control, so we should just enjoy life and not worry about it!"

Is the hypothesis true or false? False
Explain your answer, using the graph as evidence: The lines don't match up on the graph.

# data[].attributes.body
“The temperature change is caused by Cosmic Rays, not humans! There is a high correlation between the number of cosmic rays (produced by the sun) and the temperature on earth.”

Is the hypothesis true or false? True
Explain your answer, using the graph as evidence: The graph doesn't mention anything about humans affecting temperature change.

# data[].attributes.body
Independent Variable: time

Dependent Variables: number of cosmic rays(red), average global temperature (blue)

How do the trends of the two dependent variables compare? Red goes up a lot at the end, and blue stays at the middle

# data[].attributes.body
Independent Variable: time

Dependent Variables: changes in temperature, changes in volcanic activity

How do the trends of the two dependent variables compare? changes in temperature is a lot lower than changing volcanic activity

# data[].attributes.body
Independent Variable: time

Dependent Variables: temperature changes (black), observed temperature (red)

How do the trends of the two dependent variables compare? The red is spikier than the black

# data[].attributes.body
Pie Chart:

What overall trend does the pie chart show?

non linear

Line Graph:

Independent Variable: expertise in climate science

Dependent Variable: % who agree that global warming is human caused

What overall trend does the graph show? it shows the % of the global warming was caused by humans

# data[].attributes.body
Independent Variable: time in years

Dependent Variables: changes in temperature and in solar irradiance

How do the trends of the two dependent variables compare? they compare the temperature and the solar irradiance

# data[].attributes.body
Independent Variable: time in years

Dependent Variables: atmospheric carbon dioxide levels and the Mauna Loa with the global average

How do the trends of the two dependent variables compare? it compares the atmospheric carbon dioxide levels and the Mauna Loa with the global average

# data[].attributes.body
Independent Variable: contribution to global warming

Dependent Variable: % of warning effect caused by this contributor

What overall trend does the graph show in the % contribution to global warming based on the difference between human causes and natural causes? this graph shows the different between natural and human causes of global warming.
