Answer 1

projected to rise 1-8 feet by 2100
could put up to 410 million people at risk of losing their homes

Question 2

how could climate change hurricanes?

Answer 2

hurricanes could become stronger
hurricane season could be extended

Question 3

How could climate change ecosystems?

Answer 3

climate is changing so fast ecosystems can adapt quickly enough
Loss of habitat, or unfavorable growing conditions, lead to decrease biodiversity in more extinction

Question 4

how could climate change precipitation?

Answer 4

Northern US and southeast expected to get wetter
southwestern US expected to get dryer.
Seasonal precipitation. Amounts will vary
heavy precipitation Events may increase everywhere.

Question 5

how could climate change global temperature?

Answer 5

Depending on emissions, global temperatures could rise 2° to 8° by 2100
US temperatures could rise 2° to 9°
Higher latitude regions could see most warming

Question 6

why care?

Answer 6

Current rate of changes too fast for adaption

Question 7

How is climate change carbon dioxide

Answer 7

carbon dioxide level steadily increasing
Current levels around 413 ppm

Question 8

How has climate changed ecosystems

Answer 8

growing seasons have changed
Loss of habitat or unfavorable conditions have lead to changes in species range

Question 9

How has climate change to sea level

Answer 9

Global, sea level Rose, about 8 inches in the last century
Melting, ice and expansion of warm water contribute to sea level rise

Question 10

how has climate change, glaciers, and ice?

Answer 10

Glaciers in land eyes are retreating worldwide
Arctic sea ice has shrunk 13% per decade

Question 11

How is climate change to global temperature?

Answer 11

average global temps have risen 2.12° since 1880.
Not everybody has warmed
Polls have warmed much more than other places

Question 12

How has climate changed?

Answer 12

climate has always been changing
Past climate change was cyclical and slower paced
Recent changes have been faster

Question 13

Why has climate change greenhouse effect?

Answer 13

differential absorption allow short, wave lengths to pass through the atmosphere, while trapping long wavelengths
Heats the atmosphere
Greenhouse gases: carbon dioxide, methane water vapor

Question 14

how has climate change the atmospheric turbidity?

Answer 14

turbidity is the amount of suspended particles in the air
Can influence short term, transmission and absorption of terrestrial and solar radiation
1815 Tamburro volcanic eruption year without a summer

Question 15

why has climate change continent location?

Answer 15

Change in location of land masses can drastically alter amount of insulation, absorbed albedo, and ocean currents

Question 16

Milenkovitch cycles eccentricity

Answer 16

change in the shape of earths path around the sun from circular to more, oval shaped

Question 17

Milanković cycles obliquity

Answer 17

Change in the tilt of the earths axis from 21.5° to 24.5°.

Question 18

Milanković cycles precession

Answer 18

Wobble of the earths axis

Question 19

Milanković cycles

Answer 19

Variations in the earths orbit, which influence climate by changing the distribution of solar radiation
Change every 26,000 to 100,000 years

Question 20

Dark cool patches on the surface of the sun, solar storms
Distinct 11 year cycle
Mini sunspots, equal more active son, higher solar output equals warmer temps

Answer 20

Sunspots

Question 21

using tree ring, size to determine climate of the past

Answer 21

Dendrochronology
 Width of annual ring indicates favorability of environmental factors for growth
One ring for every year

Question 22

extra cords of sediment from Lake floor
Analyze pollen Contant
Reconstruct, vegetation patterns of the past

Answer 22

Proxy evidence lake sediments

Question 23

extract course of ice from continental glaciers
Analyze composition of air, trapped, and bubbles between water molecules
Reconstruct atmosphere composition of Past atmosphere

Answer 23

Proxy, evidence, ice, cores

Question 24

16O equals light oxygen
18O equals heavy oxygen

Answer 24

during warm years 18O levels are higher, all of the heavy oxygen able to evaporate

Question 25

extra course of sediment from ocean floor
Perform oxygen isotope analysis
During cold years 18O levels are higher, all of the heavy oxygen, unable to evaporate

Answer 25

Proxy, evidence, ocean sediment

Question 26

Preserved clues about what past climates were like

Answer 26

Proxy data
