Lecture 25 Flashcards
Describe the greenhouse effect
Traps heat in the atmosphere
What are two gasses that are invisible to infrared radiation?
O2 and N2
What are three gasses that trap heat in the atmosphere
CO2, CH4 and N2O
Why is the moon freezing if its the same relative distance from the sun as earth is?
Because the moons atmosphere doesn’t have CO2, CH4 and N2O to trap heat
What happens if we increase a greenhouse gas’s concentration?
It will deepen the troughs
The further the actual is from the black body line the more heat energy is in the atmosphere. what is this called
Global warming
Define Anthropogenic global warming
when Humans are responsible for the increasing gas concentrations that is occurring
CO2 bounces from ____ to _____ over history until the industrial revelation when it _____
low to high
Sky rocketed
The increase in the energy contained in the atmosphere does what to greenhouse gases
increases the concentration
What are three key gases of anthropogenic global warming? and how much has each increased since the industrial revolution
a) CO2 - 40%
b) CH4 Methane - 150%
c) N2O nitrate oxide - 20%
What is the difference between climate and weather?
Weather is short term and climate is long term
Define Climate change
The change in long term weather patterns, including temperature, precipitation, wind, etc due to an increase in the energy of the atmosphere
What are 3 terms that are NOT interchangeable
a) Greenhouse effect
b) Global warming
c) Climate change
What is the IPCC and when was it formed and by who
The intergovernmental panel on climate change in 1988 by the united nations
What is the goal of the IPCC
To recognize the problem of potential global climate change without any political influences
What is the role of the IPCC
Is to assess the scientific, technical, socio-economic literature
How many IPCC groups are there and what are the names? and what do they do
a) Working group 1 - Assess the scientific aspects of the climate system and climate change
b) Working group 2 - Assess how climate change will effect the population
c) Working group 3 - works on what we are going to do about the climate change
In 1990 IPCC work group 1 published what
A broad overview of climate change science and a discussion of uncertainties and evidence for global warming
In 1995 the IPCC work group 1 published what
the balance of evidence suggests a discernible human influence on global climate
In 2001 the IPCC work group 1 published what
most of the warming of the past 50 years is likely (66%) to be attributed to human activities
In 2007 the IPCC work group 1 published what
Warming is unequivocal and most of the past 50 years is likely (90%) due to increases in greenhouse gases.
True or false; Climate change will continue to change in the future even if we stop using harmful substances today
True
Limiting future climate change will require what
substantial and sustained reductions in emissions
Global mean surface temperature has ______ _____ since 2012
significantly increased
True or false; Each of the last 5 decades have been successively warmer at the earths surface than any preceding decades since 1850
False; 3 decades
What accounts for the most energy stored in the climate system?
Ocean warming
