Test hints  Exam is on Chapters 5-8  Chapter 9 and chapter 10 material: not on this exam  Info from guest speaker is fair game  Know residence time and radiant potential  Be able to list at least 2 greenhouse gases and explain their functions in society o I.e. Black carbon is soot that comes out of a poorly tuned car engine. Really bad greenhouse gas  Know about albedo (from guest speaker lecture) o Reflectivity o How much a surface reflects/retains energy  Know LECZs (what it is) o How vulnerable are people around the world and where are they o If you are at less than 10m elevation  low elevation coastal zone o Adaptation vs. mitigation  Know that Latitude increases as you go towards the poles  Know that the Earth has a 23.5 degree tilt  Know forms of evidence for climate change, such as ice cores (also from guest speaker lecture) Intro and Overview: Architecture of the Planet  Know the difference between the weather and the climate o Weather: temperature in terms of numbers o Climate: what the conditions were a certain number of years ago, and what we can expect based on those conditions  The “architecture” part of the planet is in reference to its surface o The biosphere is the zone of life  It is about 10 miles thin, and it is very fragile  It makes up about ¼ of the earth’s radius  This concept can be thought of like the skin of an apple  Think of the biosphere as the skin Climate Basics  When we think about climate change, the change taking place is actually very minimal o This change is measure in parts per million (ppm), so obviously it is very small!  Even though that it is small, due to the delicate balance of elements in the atmosphere, when we discuss possibilities of doubling some of these elements it actually makes a huge difference in the environment  We are seeing rates of change now that are equivalent to those observed during the Pleistocene (the last ice age) o This is because of human impact  Climate is the long term pattern of the weather o Two factors play key roles  Circulation of the air and water  Topography o The tilt of the earth gives us the seasons we experience because of how the sun hits certain parts of the globe (the angle affects which areas get more sun)  Tilt of Earth is 23.5 degrees  We have a big heat transfer system o Rays heat up the biosphere o The earth is constantly rotating on an axis, which generates heat. There is a surplus of this heat, and the excess is sent through the planet and constitutes the heat that we feel o The Tropics constitute an area of the earth that has the same degrees as the earth’s tilt, so there is full complete sun  Continental and maritime influences on precipitation distribution o Ie. Fargo, North Dakota is the center of the North American continent  The land here heats up and cools down faster than water  This causes the possibility of 100-degree weather in summer and below 0 degree weather in the winter  Cells: defined by physical properties of water vapor o Heat rises at the equator and goes to Hadley, Ferrel, and Polar cells, loses some water content, and air masses move o Doldrums are winds at the equator o Trade winds are the surface expressions of Hadley Cells o Westerlies winds describe the movement of different air masses and how they collide Inter-tropical convergence zone  Where wind masses meet  They undulate around the equator and follow the sun o In the summer, ITCZ is going north and bring a lot of rainfall to places that don’t get much rain   Leads to monsoons Topography:  Temperatures get lower as you get higher in elevation  As air ascends up the side of a mountain range, the temperature goes down and it loses its ability to hold the same amount of moisture o This leads to precipitation Koppen-Geiger Climate Classification System  A system of characterizing climates around the world based on temperature and precipitation  H climates have a high elevation which causes them to behave differently, as though they are at a higher latitude, such as Tibet and Ethiopia Water Cycle  Ice and show gets stored on tops of mountains (snow caps) o Turns into runoff and discharges into ground water o Begins to evaporate Biogeography  The patterns of life in the atmosphere  Includes the study of distribution of life forms across space and through time  (Net) primary productivity o Plants take in CO2 from atmosphere, it is used in photosynthesis, and produces a byproduct of 02, which is what we need in the atmosphere to survive o Appropriated energy = energy from the sun  This gives us short wave radiation that heats up everything Biome  Areas with similar climatic conditions, referred to as ecosystems o Factors include:  Latitude  Humidity  Elevation  Biodiversity Soils  Considered the “skin” of the earth  Interfaces between lithosphere, hydrosphere, atmosphere, and biosphere  Soil is the end product of the influences of climate, topography, biotic activity, and parent materials People:  John Harrison o Designed the prize of the Longitude Act, which was a competition aimed at determining a way to measure longitude  His prize that he designed was a frictionless clock Food!  Food Web o The sun is a huge component of this o Different levels that describe how different organisms eat each other o We are of the higher trophic levels because we aren’t eaten by anything else o People:  Michael Pollan  The Omnivore’s Dilemma o Describes how we have so many options of what we can eat, and that because of this there are certain things that we should eat and what these include  …And human evolution o Agriculture can be considered “unnatural selection” due to mutations and how we manipulate species to mate  GMOs to food Domestication  ***Know the general dates of plant and animal domestication and know a couple of animals that have been domesticated and be able to tell that story***  Selective breeding of animals and plants for human use o For highest yields, disease, resistance, and behavior o Involves genetic change o We really have been doing this for thousands of years through selective breeding and grafting  ***Three Sisters*** o Know this o These are the three main agricultural crops of different Native American groups  Winter squash  Maize (corn)  Beans o They tend to be planted close together  Animals o Dogs were the earliest domesticated animals o Sheep, goats, horses, llamas, donkeys  Plants o Middle East  Rye, figs, wheat, barley o Americas  Squash, maize potatoes, peanuts, chilies, tomatoes o China  Rice, millet o Africa  Sorghum, pearl millet o New Guinea  Sugar  Domesticated here, then went to India, and then Khanda was created (juice  crystals)  Columbus received sugar cane cuttings to plant in the New World  Was always associated with slavery until recently  People: Sidney Mintz o Sweetness and Power  100 million people left home to establish new lives in other continents, and half of them were cutting cane and making sugar for the other half  Bananas and yams o There were 3 revolutions  Neolithic revolution, urban/economic growth in Europe b/w 1000-1340AD, and Global origins in North America  Impacts o Ecosystems become simplified o More food is available (you can make higher yields and can store surplus) o Increase in population  more environmental needs o Cities rise o Deforestation, overgrazing Roman Agriculture  Imported grains from subject countries in their empire to keep everyone fed  Wheat = staple  Geometric system to lay out crop lands  Latifundia = large estates using slaves from conquered lands  Crop rotation Microparasites, Macroparasites  People: o William McNeil  Professor at U of Chicago  Microparasites = viruses, bacteria  Macroparasites = criminals, unjust rulers, dysfunctional institutions  Thinks bureaucracy arose as a replacement for spoils taken by despots  His idea is that institutions play a big role, it is not just about individuals in their own decisions  Theory of civilization and that it is predicated on the idea of surplus: when you grow surplus you make money Industrialization of Agriculture in the US  1892: First petrol-driven tractor o Steam-driven pieces of equipment were its predecessor  1907: First manufacturing plant  19202-30s: Tractors replaced horses  1950s: Chemical farming developed o Using inorganic fertilizers, herbicides, fungicides, pesticides  People  Basch  Breakfast cereal o Corn flakes were invented by Kellogg as a cure for hyperactive sexual appetites o Actual ingredients and their cost  Grain is $0.09  Advertising is $1.02  You pay the company to sell you the cereal Mechanization of the American Farm  Plows o Thomas Jefferson invented a plow that worked well on the Eastern Seaboard but it didn’t work well in the Midwest o John Deere created the wrought iron mouldboard in 1837  Transition from animal to machine power was complete by 1960, which was a huge advantage  By 1962 USDA no longer kept track of how many horses and mules were kept on farms  After 1900  Era of Power Farming Third stage of industrialization  Food manufacturing arose in the 1960s  Large farms came into being  It became super expensive to have a farm, yet they were treating farms like firms o CAFO’s (concentrated animal feeding operation)  Often get a bad rap for poor animal treatment Supermarkets  Agribusiness o Cargill sponsors public radio o ADM (archer-Daniels-Midland): the informant o Bunge Ltd o J.R. Simplot: Fast Food Nation, became huge supplier of potatoes and dehydrated onions to US military during WWII  History o 1859: great Atlantic and pacific tea company (A & P) o 1916: Piggly Wiggly in Memphis  Self service shopping o 1920s: chain store explosion  Kroger, American stores, Safeway o 1930s-40s: supermarkets o 1950s-60s: golden age  Larger square footage  Automobile access  Shopping carts o 1970s: warehouse  Kroger, Harris Teeter o 1980s-90s: mergers  Warehouse stores, Wal-mart o 2000s: consolidations  Safeway + Albertsons o Significance:  Epitome of choice  All about institutions The Kitchen!  In the 1950s, kitchens were promoted to the front of the house: central place of home o Used to be that servants would make food out of sight  Even when women began to join the workforce they were still expected to cook for their families o  Open floor plan: allows family members to serve themselves Climate Change  Between 1/3 and ½ of the earth’s land surface has been transformed by human action  “The Day After Tomorrow” is a disaster movie  Climate change = global warming + climate variability o It is a form of air pollution but it affects the entire planet to various extents o Results from things like combustion  We have a rising concentration of greenhouse gases in the atmosphere, especially CO2 and CH4, which trap infrared heat which would normally be lost to space o CO2 is produced by burning things, fossil fuel, and deforestation  Carbon sinks  Areas that absorb carbon, like a forest o Deforestation does a huge disservice since CO2 levels are rising o CH4 is produced by cattle, rice production, landfills, and gas pipelines  The “greenhouse effect” is normal because it is what gives us our atmosphere on Earth o Think of how a car absorbs heat, same with Earth:  Short wave radiation goes to the surface of the planet, some is reflected back, gases absorb some energy, but it mostly goes to Earth’s surface  CO2 and temperature o The concentrations of greenhouse gases are increasing which is making temperatures increasing  Evidence of this direct relationship is due to ice cores o Gaia Hypothesis: planetary regulation  The idea of the planet as one large organism and how it is self-regulating  Certainties with Climate Change o There is a natural greenhouse effect that makes for a livable climate on earth  It is at least 15 decrees C warmer than without it  Venus is so hot- if our temperatures continue to rise, we could end up like Venus! o Nearly universal consensus of temperature rising o Clear association between rising temp and gas levels o IPCC is 95% certain that humans are a primary cause of climate change o Areas of agreement  Atmospheric concentrations of greenhouse gases are increasing  CO2: 280ppm in 1750 400ppm today  CH4: 0.9ppm in 1750 1.75ppm today  Uncertainties associated with climate change o Scientists are skeptical about behavior of carbon in atmosphere  How much/how long do CO2 and CH4 remain in atmosphere  Many Q’s  How much carbon is recycled through plants/oceans  More deforestation in tropics  Will soils emit more carbon in a warmer world? o Radiative effects (ability to attract heat) and residence times (how long it stays in atmosphere)  CO2 has a long residence time but milder radiative potential  CH4 has a shorter residence time but has 20 times the radiative potential  20 times more effective of trapping gases o You really don’t want methane in the atmosphere  CFCs have a long residence time and a high radiative potential and it destroys the ozone layer  These have been banned o New and improved modeling efforts  Linked models run the same parameterized routines for smaller and then link the results back to the larger global model  Feedbacks between land use/land cover and atmospheric circulation o Could climate be changing for other reasons?  Changes in solar input?  Changes in earth-sun geometry?  Milankovitch theory of ice ages o Looked at places where earth seems to be wobbling on axis, which he thought were cause of ice ages  Changes in surface characteristics like reflectivity, roughness and surface wetness  Deforestation affects these  Changes in atmospheric composition  I.e. volcanic activity  aerosols o With greenhouse cases, don’t contribute much o Has global warming already occurred?  Yes…  Urban heat island effect  People live in cities, building warm up ground  Weather stations are often located at airports o For aircraft reasons o Think about Dulles and urban heat effect, how it used to be “out there” but as area became more developed, could this have contributed to temp rising?  “Hotlanta” o Asphalt, concrete buildings, o In Atlanta  Intergovernmental Panel on Climate Change (IPCC) o International body for assessing the science related to climate change o Produce a lot of graphs  I.e. the variation in the Earth’s surface temperature  Impacts of climate change o Higher temperatures  All around planet  Sensors tell us this  Main temp changes occur at poles o Modified rainfall patterns  Wet areas have been getting wetter, dry areas have been getting dryer o Sea level rise o Natural ecosystem changes  Weeds grow better in higher temperatures, rise in weed growth o Challenged water resources  Rainfall to areas that are super dry o Opportunity for better governance?  Observed Impacts o 20 century average surface temperature +0.8 degree C  A greater rate of change than any seen in more than 10,000 years o Decreasing snow and ice cover th o Sea level rise 1-20 cm in 20 century  Melting/thermal expansion o Precipitation + 0.5 – 1% per decade over mid-high latitudes o Projected impact: if trends continue, a temperature rise of 3 degrees C will occur before the end of the next century  Limitations on predicting the future o General circulation models  GCMs are models, complex computer simulations  Models where certain parameters such as CO2 can be modified  Hard time predicting what storm path will be  Best tools available  Limitations  Results vary among models  Simplistic representations of oceans, ice, clouds o Makes precipitation predictions uncertain  Model resolution and topography are coarse  Only do somewhat well reproducing current conditions  Cannot predict climate variability and extreme weather  Global climate change response o Impacts  Mitigation: reduce impact  Reducing amount of greenhouse gasses emitted per year  Europe has a reason to worry  Extreme cooling due to possible loss of warm ocean currents  London is very north, but has a lot of green and doesn’t stay warm  Europe stays very warm from gulf stream bringing warm water from tropical Atlantic  Thermohaline circulation sends Europe into a deep winter o Big temperature conveyor belt o Big fear is that this will slow down and will send Europe in to deep cold winter  Drought  Dry land Africa- drought in western and southern Africa o Removed surface vegetation has effect on surface conditions o Rainfall variability modulated by vegetation dynamics o Species loss o Impacts on livelihoods o Food impacts o People decide to have more kids as a result  Western US o CO is dependent on snowpack for water o CO river basin is experiencing a 55 percent drop in average snowmelt o Since 1999, the driest of 98 years of recorded history  2 years of successive dryness = drought  BAU: “business as usual”  If we don’t do anything different…  Assumes people will not want to change o Adaptation o Global climate equity issues  Trouble at the poles o Most startling changes are in the high latitudes o Permafrost is becoming less and less common  A piece of ground that has remained frozen for at least 2 years o Albedo = reflectivity  Impacts on the Cryosphere o Some models predict that all permanent ice will be gone by 2080  Many controversies o Greenland has 8% of world’s freshwater supply o Sea ice meting does not affect sea level  Already displacing an equivalent amount of sea water  Antarctica ice shelf has been melting more quickly  Sea level rise o People:  Michael Oppenheimer, professor of Geosciences and international Affairs (Princeton university) st  If there is a 3 degree warming over the 21 century there would be complete melting of the Greenland ice sheet,  7 meter sea level rise worldwide o Southern Florida would be completely covered o For every 1 degree of warming, = 2.3 meters of long term sea level rise o All ports at sea level would be gone o Farming at sea level would be gone o Whole areas of the world would have to be remade o London…  Protect or abandon?  Depends on pace of sea rise  LECZs o Took all of censuses of world and put into 1km grid  Estimated populations at risk of sea level rise o About 2.2% world land area  11% population lives here  China is biggest  Then other Asian countries who are vulnerable to sea level rise Info From Guest Speaker Lecture (whole lecture is fair game for exam)  A Path to Regulation and A Career o Clean Air act: 1970  Regulate motor vehicles (air pollutants that come from them)  Once you’ve regulated a pollutant under one section, you can do others o Greenhouse gasses proving they are air pollutants  If they are a danger, regulation is necessary  2009: final endangerment finding  Climate Science o What drives it  Greenhouse gas concentrations  Aerosols (warming or reflecting)  Cutting trees, changes in sun and clouds o Changes on a physical scale  Temperature, precipitation, sea level rise  Many uncertainties  Non-climate changes like fertilization o Impacts  Human health from changes in heat, air quality, mosquito inhabitance  Infrastructure  Sea level rise  Agriculture  Drought  Ecosystems  CO2 Concentrations o 1950s: people began to realize that we were influencing CO2 levels o 800,000 years of CO2 history  Correlated with ice ages and interglacial o How do we know?  People take ice cores  You get bubbles trapped in ice from layers of snow over time  You can see layers and determine when the bubbles came and the concentration of the gas in it o People:  Ralph Keeling began to measure CO2 concentration in late 1950s o We care because it absorbs infrared radiation o Climate variability from el Niño/la Nina years  Cooling from volcanic eruptions  Future projected temperatures o Temperature change over next century will be a lot greater than past century o Warming is not uniform… more warming over land  Indicators of climate change o Sea level rise o Ocean heat content o Artic sea ice o Upper atmosphere temperatures o Glacial melt o Plant bloom dates o Bird migrations o Insect habitable zone o Changing precipitation patterns o River thaw contests  Summary o GHG’s have changed composition of atmosphere o Average temps are rising, artic sea ice and glaciers are shrinking o What is happening now cannot be explained by natural factors alone o Gases stay in atmosphere for many years, so we are committing ourselves to continued climate change o Balance between mitigation, adaptation, geo-engineering, and inaction Climate change vulnerability in metropolitan NY o Close to 600 miles of coastline o 4 of 5 boroughs are situated on islands connected with 80 bridges and tunnels o It is hard to link disasters (i.e. Hurricane Sandy) directly to climate change  Storm surge is very impactful  Potential impacts of climate change and sea-level rise  Flooding underground in subway  Dangerously hot summers  Mosquito borne diseases  Stressed water supplies o Salt water intrusion  Loss of beaches o Airports are very vulnerable o We could lose Southern Florida if an ice shelf crashes… worst case scenario o A sign of climate awareness is when insurance goes up Benefits of climate change?

 People have different responses to drought  Production systems have already changed/are prepared, but they lack resources o People move o How to adapt with…?  Bangladesh  Philippines  Maldives could disappear  Boston: could have  Permeable streets  Other adaptations Opportunities o GeoEngineering  Aka climate engineering  Deliberate intervention in Earth’s climatic system with aim of limiting adverse climate change  Two types  Carbon dioxide removal (sequestration)  Solar radiation management  Almost all research into solar geoengineering has consisted of computer modeling  Types  Albedo modification o Painting roof white to change reflectivity  Less energy gets absorbed by surface and more gets reflected  Tree planting  Stratospheric aerosols o Aerosol = what volcano does  Carbon sequestration o I.e. deforestation o Just take carbon out of coal  Iron filings to stimulate growth of phytoplankton o Carbon sinks, stimulate their growth  Chemtrails o Conspiracy theories that people spray these now  Dangers o These could all lower temperatures, but then we would become dependent on it, makes for an unstable situation  I.e. whoever owns the sunshades, war, take control over it, catastrophic event o Expensive o Irreversible actions Global climate equity o Americans consume about 4 tons of crude oil per capita/yeah o We produce the same amount of GHG as 4.5 Mexicans, 18 Indians o Who is responsible for past and present GHG emissions?  Formulating a greenhouse index  IPCC- factor in residence time of GHG  WRI – look at one year at a time based on current mix of atmospheric gases o “China is to blame”  They produce most GHG  Weaknesses of the two approaches  IPCC- don’t really know residence times, make assumptions o Cry from the south: bias against developing countries  Emissions are not measured as having accumulated over time  Developed countries are mainly responsible for today’s build-up  Today’s deforestation in various places is weighted o People o Anil Agarwal  Founder of Centre for Science and Environment (one of India’s leading environmental NGOs)  Credited as one of the inspirations for the term sustainable development  Luxury emissions vs. survival emissions Cap and trade idea o Came from republicans, set a market for carbon o Like giving people tickets to emit a certain amount o If people don’t use all of it they can bank the money o McCain was a supporter of acting in climate o Clean Energy and Security Act  Not passed by senate More on mitigation o Cost of inaction  Total cost of climate action in 2100 is about $12 trillion and cost of inaction is $20 trillion  Costs are bigger in 2200 Steps to be taken o Emissions trading  Cap and trade idea to bank money and make savings o Ecological taxes  Instead of taxing people based on income, tax on environmental impact o An international kerosene tax  Fuel made of coal, producer of black carbon o Financial incentives that favor climate-friendly renewable energy technologies  Tax breaks Achievable carbon emissions reductions resulting from household actions o KNOW THE GRAPH ON THIS SLIDE  PER = potential emissions reduction o Behavioral plasticity = how likely are people to adopt change? (Is in % in table)  Carpooling is a good example of how everyone thinks it is a great idea but no one wants to get out of their car  Look on emissions of different things on table o RAER  Behavioral change x likelihood it will happen Climate responses o Mitigation o Adaptation o Resilience  Disaster resilience: ability to prepare and plan for adverse events  Actions to take to become more resilient?  Implies that we are special and can handle whatever is thrown at us  Population o “The population bomb” book  Population debates o “Cassandras” vs. “cornucopias”  Cartoonish way of looking at it  Cassandra could see the future, no one believed anything she said  In terms of population, same: people saying that the population is increasing too rapidly, if we don’t do something about it, x, y, and z will happen o No one acts on it, people don’t believe it  Cornucopia: constant supply of food, no regulation, always two hands o Policy shifts to women’s reproductive health, 1990s  Whole deal with birth control as a means of population control  And then to retreat, then return o New policy issue: “Implosionism” in the developed world especially in Japan and Europe  Explosion in African countries  If you go to Spain of Italy, Japan, soon China  Fewer babies being born that will keep population at current level o Population issues continue to be critically important and are often neglected  Population basics o World population clock o Growth occurs when the number of births exceeds the number of deaths  Right now population is growing at a rate of ~148 people per minute  But rate of growth is slowing o Vital rates  Birth rate = births per 1000 people  Counted through hospital, collected by counties  About 13.8 in the US  Death rate = deaths per 1000 people  Counted through death certificates  About 8.4 in the US  Rate of natural increase % = (birth rate – death rate)/10  13.8-8.4 = 0.53%  Mexico has a higher growth rate than US, why? o Mexico has a younger population and usually odds of dying younger aren’t as high as dying older o Flow of immigration o Role of migration  Can alter population growth rates  In the US, about half of growth comes directly from immigration  Influences fertility  In US, immigrants prefer to have larger families  82% of population growth between 2005 and 2050 in US will be from immigrants o Fertility rates  The average number of children a woman will have in her reproductive career within an age range  TFR = total fertility rate o NOT a percentage  US: 2.1, Mexico = 2.2  Pro-Natalist  Everyone has kids, society where this is encouraged and more kids is better  Niger, Burkina Faso have super high TFR  Child mortality plays a role here:  If you don’t believe your kids will survive, then you have more to counter this so that the chances of some living are higher.  Why do fertility rates decline?  Countries where this has happened o China has a one-child policy o Mexico issue o Thailand o Kenya o Ghana o Niger  Reasons o Status of women  Access to work and cash? Separate bank accounts? o Economic conditions o Infant and child mortality o Education (especially for girls) o Family planning efforts o Cultural and religious factors  Breastfeeding o Government policies  Role of family planning picture in Niger o Demographic transition  Long-term reduction of fertility follows reduction of mortality  Changes in water quality, hygiene, sanitation, vaccinations  Specific conditions vary by region and culture o Age Structure  Younger populations will have ‘longer influence’  Ie. Saudi Arabia: 38% under 15, so attitudes about children is changing  This is “Population Momentum”  This will cause population to grow rapidly when the population reaches reproductive age o Baby boom! o Battles between countries/states about who has the most kids  Power  Political power  Status  Pro-natalist societies “threatening” each other by having high numbers of children o Population as a cause of environmental problems  Malthusianism  Dismal Theorem o Thomas Malthus inspired Charles Darwin o He argued that population grew geometrically (2,4,8,16) and that food supplies only grown arithmetically (2,4,6,8) o Eventually we will run out; there won’t be enough food for the entirety of the population o Starvation would keep the population in balance o Carrying capacity is exceeded when population outstrips food supply o We behave like fruit flies o Other argue that population is a root cause of environmental degradation  Countdown o Alan Weisman  Jerusalem: battle of the babies  Put two pro-natalist groups together, population explosion o After WWI, carrying capacity increased dramatically  Criticisms o By cornnucopians and technological optimists  Think population is not a problem because we can increase food supply through technology  The Ultimate Resource: people are viewed as resources o By redistributionists  High consumption by people in western countries is the problem, not women having too many kids  If distribution was equal, everyone could be fed  Population is a symptom of environmental problems  Reason for high fertility: need for child labor  Policy solutions: coercive tactics o China’s one child policy o India’s forced sterilization policy o US Eugenics movement (1910s-20s)  Improving genetic quality of human population  Sterilization for handicapped
