About what percentage of heat trapped by greenhouse gasses goes into
heating the oceans? - Precise Answer ✔✔About 93%
What are the 2 key contributing factors to the rise in sea level? - Precise
Answer ✔✔The melting of ground ice & water expanding as it heats
T/F: The warming over the past century is around 16 times faster than
the average rate of warming coming out of the last ice age. - Precise
Answer ✔✔True
How can scientists use tree rings to extract climate information? -
Precise Answer ✔✔Because tree growth follows an annual cycle that is
imprinted in the rings in their trunks, scientists can measure the size of
rings & estimate the local climate around the tree for each year it was
alive.
What is the most important rule of the Earth's climate? - Precise Answer
✔✔Energy Balance—The Energy reaching earth from the sun must be
equal to the energy the earth radiates back to space.
What is meant by greenhouse effect? - Precise Answer ✔✔Greenhouse
gases are a part of the atmosphere that absorb infrared radiation. These
,gases reduce the amount of power the Earth radiates to space, therefore a
planet with more greenhouse gases in the atmosphere must be warmer
than one without.
What Swedish scientist first recognized the possibility that as the mass
of greenhouse gases in our atmosphere increases, the atmosphere traps
more heat, leading to higher temperatures? - Precise Answer ✔✔Svante
Arrhenius in 1896. British engineer Guy Callendar provided more
supporting evidence for this possibility in 1938.
What are the 3 simple molecules contained in Earths atmosphere that do
not interact with infrared radiation & therefore generate no greenhouse
effect? - Precise Answer ✔✔Nitrogen (N2), Oxygen (O2) and Argon
(Ar)
What is the most important greenhouse gas? (Meaning it traps the most
heat) - Precise Answer ✔✔Water vapor, with carbon dioxide as the next
largest contributor.
What is a Keeling Curve? - Precise Answer ✔✔The Keeling Curve,
named after Charles D. Keeling, is a graph which plots the ongoing
change in concentration of carbon dioxide in Earth's atmosphere since
1957.
Scientists have observed that, for the last 50 years, the increase in carbon
dioxide in the atmosphere averages 44% of what humans released that
year. What happens to the other 56% of carbon dioxide released by
humans? - Precise Answer ✔✔About half is absorbed into the ocean,
, leading to ocean acidification & the other half is absorbed by the land
biosphere by enhanced growth.
Methane is an important greenhouse gas. While it's PPM increase in the
atmosphere is much smaller compared to carbon dioxide, it's a
significantly more powerful greenhouse gas on a per-molecule basis.
What is the per molecule ratio measured in kilograms of heat trapped
between methane & carbon monoxide? - Precise Answer ✔✔1 kg of
Methane = 28 kg of carbon dioxide
What is Global Warming Potential (GWP)? - Precise Answer ✔✔The
heat trapping power of GHGs relative to carbon dioxide.
What are the atmospheric lifetime & GWP of Nitrous Oxide? - Precise
Answer ✔✔121 years & 265 GWP
What are the atmospheric lifetime & GWP of halocarbons? - Precise
Answer ✔✔Years to Millenia & 100s to 1000s GWP
T/F: Aerosols have a net effect to cool the climate. - Precise Answer
✔✔True! Aerosols can remain suspended in the atmosphere for days or
weeks & can reflect incoming solar radiation back to space, making their
net effect to cool the climate. They can also affect cloud formations,
making clouds more reflective which is an additional cooling
mechanism.
