global warming?

A

the increase in the average measured temperature
of the earth’ s atmosphere and oceans

21
Q

the increase in the average measured temperature
of the earth’ s atmosphere and oceans

A

global warming?

22
Q

The average global air temperature
increased by about _____°C over the
past 100 years

A

1.18

23
Q

Greenhouse Effect?

A

a process by which solar radiation is absorbed by greenhouse gases and the temperature of Earth’s atmosphere is increased.

24
Q

a process by which solar radiation
is absorbed by greenhouse
gases and the temperature of
Earth’s atmosphere is increased.

A

Greenhouse Effect?

25
Q

Greenhouse gas

A

absorbs radiation at
specific wavelengths within the spectrum of radiation (infrared
radiation) emitted by the Earth’s surface and by clouds.

26
Q

absorbs radiation at
specific wavelengths within the spectrum of radiation (infrared
radiation) emitted by the Earth’s surface and by clouds.

A

Greenhouse gas

27
Q

Greenhous gas 2

A

The gas in turn emits infrared radiation from a level where the
temperature is colder than the surface.

28
Q

emits infrared radiation from a level where the
temperature is colder than the surface.

29
Q

CLIMATE CHANGE

A

any change in climate over time, whether due to natural variability
or as a result of human activity

30

or as a result of human activity

A

CLIMATE CHANGE

31
Q

causes climate change
(arrow)

A

BURNING OF FOSSIL FUELS & DEFORESTATION AND BIOMASS BURNING
->
“ENHANCED” GREENHOUSE EFFECT
->
GLOBAL WARMING
->

32
Q

10 indicators of a warmimg world

A

HIGH:
ocean heat content

sea level
temperature over oceans
humidity
air temp near surface (troposphere)
temp over land

LOW:
sea ice
glaciers
snow cover

35
Q

Albedo Effect

A

reflectivity of an object in space using a term called albedo. This is the amount of electromagnetic radiation that reflects away, compared to the amount that gets absorbed

37
Q

Glacial Melting

A

Himalayan glaciers are melting twice as fast now as they were before the turn of the century. Scientists combed 40 years of satellite observations spanning 2,000 kilometers (1,243 miles) across India, China, Nepal and Bhutan, and found that the glaciers have been losing the equivalent of a foot -and-a-half (45 centimeters) of ice each year since 2000.
