1 Today Terrestrial Planets Earth, Venus, Mars Atmospheres Climate Greenhouse effect from planetary perspective Factors affecting atmospheres EXAM NEXT TIME
2 Why the sky is blue Atmosphere scatters blue light from the Sun, making it appear to come from different directions. Sunsets are red because less of the red light from the Sun is scattered.
3 Radiation Protection All X-ray light is absorbed very high in the atmosphere. Ultraviolet light is absorbed by ozone (O 3 ). There is no hard line - really exponential attenuation
4 Earth s atmosphere absorbs light at most wavelengths. The air looks clear to optical light & radio waves; looks like a brick to X-rays and like a fog to the infrared.
5 Planetary climates Temperature depends on balance between Heat input from sun distance dependent Heat loss to space atmosphere dependent (natural greenhouse effect) transparent gases (N2, O2) irrelevant greenhouse gases (e.g., H2O, CO2) important even if only a small part of the atmosphere
6 The Greenhouse Effect
7 Greenhouse Gas Any gas that absorbs infrared Greenhouse gas: molecules with two different types of elements (CO 2, H 2 O, CH 4 ) Not a greenhouse gas: molecules with one or two atoms of the same element (O 2, N 2 ) Though oxygen and nitrogen compose the bulk of the atmosphere, they do not absorb in the infrared so don t contribute to the greenhouse effect
8 Main greenhouse gases (on the Earth) all are < 2% of atmosphere, but provide Water (H 2 O) ~60% of infrared opacity Carbon dioxide (CO 2 ) ~22% Methane (CH 4 ) ~7% Others (ozone, CFCs, nitrous oxide) ~11% Note: water vapor absorbs more IR than CO2!
9 Greenhouse Effect: Bad? The Earth is much warmer than it would be without an atmosphere because of the greenhouse effect. That s good! (cf. the moon) the same can be said for Venus, only more so...
10 Why is Venus so hot? The greenhouse effect on Venus keeps its surface temperature at 470 C (878 F). That s higher than Mercury, even though it is farther from the sun. The difference is the greenhouse effect. Why is the greenhouse effect on Venus so much stronger than on Earth?
11 Atmosphere of Venus Venus has a very thick carbon dioxide atmosphere with a surface pressure 90 times that of Earth. That s equivalent to nearly a kilometer beneath the surface of the ocean.
12 Greenhouse Effect on Venus Thick carbon dioxide atmosphere produces an extremely strong greenhouse effect. Earth escapes this fate because most of its carbon and water are in rocks and oceans.
13 Carbon cycle on Earth
14 Carbon Dioxide Cycle 1. Atmospheric CO 2 dissolves in rainwater. 2. Rain erodes minerals that flow into the ocean. 3. Minerals combine with carbon to make rocks on ocean floor.
15 Carbon Dioxide Cycle 4. Subduction carries carbonate rocks down into the mantle. 5. Rock melts in mantle and outgases CO 2 back into atmosphere through volcanoes.
16 Runaway Greenhouse Effect More evaporation, stronger greenhouse effect Greater heat, more evaporation Oceans evaporate; no longer absorb CO2. CO2 builds up in atmosphere unchecked runaway greenhouse
17 Mars: the opposite extreme Low gravity and a thinning atmosphere led to a runaway icehouse. Mars atmosphere currently ~1% as thick as Earth s
18 2004 Opportunity Rover provided strong evidence for abundant liquid water on Mars in the distant past. How could Mars have been warmer and wetter in the past?
19 Climate Change on Mars Mars has not had widespread surface water for 3 billion years. The greenhouse effect probably kept the surface warmer before that. Over time, Mars lost most of its atmosphere.
20 Factors affecting atmospheres Lightweight gases (helium) Oxygen! Can break up water vapor; hydrogen escapes Water can freeze out 20
21 Mars atmosphere was thicker in the past; its climate was warmer - liquid water! The atmosphere was gradually lost to space or frozen onto surface 21
22 Today, most Martian water lies frozen underground (blue regions) Some scientists believe accumulated snowpack melts carve gullies even today.
23 close to sun Planetary climates Mercury (no atmosphere) Hot on day side, cold on night side Venus (thick atmosphere) Hot all the time (hotter than Mercury!) Earth ( nice atmosphere) just right Moon (no atmosphere) Hot on day side, cold on night side Mars (thin atmosphere) far from sun colder now than in past same distance from sun
24 The anthropogenic greenhouse effect (Global Warming and human activity) What is real information? What is misleading? Should we be worried?
25 Evidence of global warming Increase in greenhouse gas concentrations Surface temperature measurements Ocean temperature measurements Sea level rise (water expands as it warms) Melting arctic icecap; retreating glaciers Poleward migration of species More extreme weather events both warm & cold; hurricanes; snowmageddon Melting permafrost
26 Arctic permafrost is melting 26
27 Fabled Northwest passage opened for first time in history
28 The Earth s climate is out of equilibrium - heat is accumulating in the ocean faster than it is being radiated into space.
29 CO 2 Concentration T CO2 interglacial ice age ice age ice age 400, ,000 0 time (years before present) Global temperatures have tracked CO 2 concentration for the last 500,000 years. Antarctic air bubbles indicate the current CO 2 concentration is at its highest level in at least 500,000 years.
30 CO 2 Concentration T CO2 400, , time (years before present) There has been a sharp increase in CO 2 over the last 50 years. Amount consistent with the fuel burned.
31 1000 Year (A.D.) 2000
32 Pre-industrial CO2 level CO2 added to atmosphere Human activity Carbon burned 1000 Year (A.D.) 2000
33 33
34 Climate Change Forecasts The recent temperature increase is consistent with human production of greenhouse gases. Basic physics simple; detailed predictions hard. We are changing the composition of the atmosphere we rely on.
35 Policy implications Basic trend clear but detailed long range forecast challenging. Probably some winners as well as losers Probably a bad idea conduct an uncontrolled experiment on the atmosphere we all breathe & the climate we depend on. There is finite energy available in coal, oil, natural gas, uranium... Are we NOT going to use these resources?
