41. It is not possible because there are too many factors to consider. Greenhouse Gases in the
atmosphere are already high and we would not be able to reduce what is already in the air
that quickly.
42. Example Sentence:
Today the Earth’s climate is changing due to the anthropogenic greenhouse gases
humans are responsible for producing.
43. Greenhouse gases act as a “energy trap” by blocking the radiated heat from the surface of
the earth from escaping back into space. The atmosphere, as a result is warming and more
greenhouse gases are trapped and as more greenhouse gases are being produced.
44. Proxy Records: are preserved physical characteristics of the past that stand in for direct
measurements to enable scientists to reconstruct the climatic conditions that prevailed
during much of the Earth's history. Examples:
a. Ice Cores: bubbles of CO2 from ice core samples are trapped in the ice from year
past. Measurements of this gas can be used to determine how hot/cold the
temperature was during that year or specific layer.
b. Tree Rings: Bigger the ring, the better the growing conditions (warmer, more
rain)
c. Caves/Reefs: species of life and fossils indicate how life has changed based on the
temperature of the past and present.
45. Other animal species affected: Ex. Pizzly Bear/Grolar Bear, other species of birds landing
in Arctic, difference in marine life…etc.
46. Calculate using the Q=mc (delta T) formula
47. Meteorologist: A person who gathers this data and uses it to predict and share the
forecast of upcoming weather.
Climatologist: Scientists who studies the climate of any region.
48. Precipitation: is water that falls from the sky to the ground. Four forms: snow, sleet, hail,
rain.
49. (a) Calculate using Relative Humidity Formula (RH = actual/maximum x 100).
(b). 100% RH, shower mirror and room would show the formation of water droplets
caused by what we refer to as the dew point. The air in the bathroom is completely
saturated.
