What is Global Warming?“The recent increase in the world's temperature that is believed to be caused by the increase of certain gases in the atmosphere”
(Merriam-Webster)
“Global warming refers to climate change that causes an increase in the average temperature of the lower atmosphere.”
(web.mit.edu)
Greenhouse Effect Greenhouse gases absorb the infer-red radiation
reflected off of the Earth’s surface locking that heat within the atmosphere thereby increasing the temperature of the world
Biomassenergycentre.org.uk
Keeps the world warm normally “human activities, mainly related to burning of fossil
fuels, have released extra carbon dioxide into the atmosphere” along with other greenhouse gases
Packet
The extra greenhouse gases are increasing the greenhouse effect and causing the temperature of the world to increase
Effects of to Many Greenhouse Gases Climate change
More severe and random weather Mean sea levels rising
Increasing at average rate of 3.2 ± 0.4 mm/yr University of Colorado Sea Level Research Group
Melting ice caps Water expanding as it gets warmer It is difficult to make precise predictions for
why mean sea levels are rising because of factors like abnormal water expansion
Calculating the Change in Sea Level Can estimate the change in sea level
with the equation 𝛾 is the coefficient of volume
The fractional change in volume per degree of change in temperature
is the initial volume of the ocean is the change in temperature
Global warming getting worse Cars Global warming is also making itself worse
Higher temperatures reduce snow and ice cover which increase the amount of exposed surface that can reflect infer-red radiation into the atmosphere
The higher temperatures reduce the ability of greenhouse gases to dissolve in the ocean thereby increasing their concentration in the atmosphere
Deforestation The less trees, the less photosynthesis turning CO2
into oxygen
Answer to Notes1. What is global warming? (can choose either definition)
“The recent increase in the world's temperature that is believed to be caused by the increase of certain gases in the atmosphere”
or “Global warming refers to climate change that causes an
increase in the average temperature of the lower atmosphere.”2. What kind of radiation is absorbed by greenhouse gases?
Infer-red radiation 3. Where does this radiation come from?
When the Earth his heated by the sun, it releases this radiation. 4. Is the greenhouse effect normally bad?
It is what keeps the Earth warm.4.5. If not, what has made it harmful?
The increase of greenhouse gases from human activities mainly related to burning fossil fuels
Answers continued 5. What are the effects of having too many greenhouse gases?
Temperature of the world increases Climate change
More severe and random weather Mean sea levels rising
Increasing at average rate of 3.2 ± 0.4 mm/yr Melting ice caps Water expanding as it gets warmer It is difficult to make precise predictions for why mean sea
levels are rising because of factors like abnormal water expansion and the different effects of melting sea ice and land ice
6. How do you calculate the change in sea level?
is the coefficient of volume The fractional change in volume per degree of change in
temperature is the initial volume of the ocean is the change in temperature
Answers Continued7. What is some evidence of global warming?8. What is causing global warming to get worse and why?
Cars Global warming
Higher temperatures reduce snow and ice cover which increase the amount of exposed surface that can reflect inter-red radiation into the atmosphere
The higher temperatures reduce the ability of greenhouse gases to dissolve in the ocean thereby increasing their concentration in the atmosphere
Deforestation The less trees, the less photosynthesis turning
carbon dioxide into oxygen
