Global Warming and Climate Change

Question 1

What is the pre-industrial background of the Mauna Loa Carbon Dioxide Record?

Answer 1

280 ppm

Question 2

What’s the current level of the Mauna Loa Carbon Dioxide Record?

Answer 2

417ppm

Question 3

In the Monthly Mean CO2 Mauna Loa graph, what does the lines drop every now and then? (find picture in the global warming slides)

Answer 3

the line drops due to the absorption of solar energy from the forestry (in the summer time)

Question 4

What are the role of clouds?

Answer 4

the clouds absorb, reflect, and block atmosphere window.

Question 5

What is the net effect of clouds?

Answer 5

the net effect is unknown

Question 6

What are ice clouds?

Answer 6

ice clouds are net warmers, and the absorption of IR is greater than solar reflection

Question 7

What are water clouds?

Answer 7

water clouds are net coolers, and the absorption of IR is less than solar reflection

Question 8

What is the biggest factor to identify the weather climate in the future?

Answer 8

by identifying if cloud are either ice or water

Question 9

In the Global Monthly Mean CH4 graph, why does Methane increase, then stops, and reverts back to its increasing factor?

Answer 9

natural processes affects this

Question 10

What are CFCs?

Answer 10

CFCs are very absorptive, and don’t react with other gases

Question 11

What was the Montreal Protocol implemented in between 1985-1990?

Answer 11

CFCs would wind up in a thunderstorm into the stratosphere, whereas UV would hit the CFC creating a chemical reaction causing a reduction in ozone.

Question 12

What is Radiative Forcing?

Answer 12

change in net radiation arising from greenhouse gases, aerosols, etc.

Question 13

What is the pattern of radiative forcing?

Answer 13

-if there is a positive net radiation=more energy in system=warmer atmosphere
-if there is negative net radiation= less energy in system= cooler atmosphere

Question 14

What is the pre-industrial baseline of radiative forcing?

Answer 14

relative to 1750

Question 15

What are examples of net warmers?

Answer 15

carbon dioxide, methane, and nitrogen dioxide

Question 16

What are examples of net warmers and net coolers?

Answer 16

CFC, HFC, HCFC

Question 17

What are aerosols (net radiation)?

Answer 17

aerosols are net coolers

Question 18

What factor does aerosols play?

Answer 18

aerosols reflect sunlight resulting in not enough radiation in the atmosphere; produce clouds making them brighter and reflective

Question 19

What are sunspots?

Answer 19

sunspots affects the temperature making the sun hotter

Question 20

What are the patterns of sunspots?

Answer 20

-lower amount sunspots=lower temperatures
-higher amount of sunspots= higher temperatures

Question 21

What’s the relationship between solar spots and greenhouse gases?

Answer 21

solar spots decrease as the temperature from greenhouse gases increase

Question 22

How are the temperatures in El Niño?

Answer 22

temperatures are higher

Question 23

Based on the Global Satellite Temperature, what fluctuates the temperature?

Answer 23

impacts of the Pacific Ocean and volcanic eruptions causes cooling of temperature

Question 24

Where is warming highly evident during the winter?

Answer 24

warming is strongest in high latitudes during the winter

Question 25

How much has the surface temperature increase over the past century?

Answer 25

0.5 degrees C–1.0 degrees C
