Below are some illustrative (but not comprehensive) descriptions of the assumptions made by the major scenarios. ), Notes Climate Change and Climate Modeling A reading list to accompany ‟Clarity in Climate Modeling,” by Brian Hayes, American Scientist Vol. Participants must make their own travel and overnight arrangements. The frames of this animation illustrate spatial resolution of a model. In the Fourth Assessment Report, results from 23 different climate models were reported in most cases. It should be obvious from the plots that increasing CO2 has no effect on the temperature. In this simple model, the temperature is determined entirely by the atmospheric CO 2 concentration via greenhouse warming of the atmosphere. Some of these tools are global climate models.Using models, scientists can better understand how the Earth works and how it will react to change in the future.. What we do. Add to your own 2D models. The shape of the computed temperature curve should still be the same - but with an offset in the Discuss. 4-H Weather and Climate Youth Learning Lab: Activity Web site Links Activity 1: Weather Data NOAA, National Weather Service: www.weather.gov SNOTEL: vertical direction. These images illustrate the typical spatial resolution used in state-of-the-art climate models around the times of each of the four IPCC Assessment Reports. Models use grids of "cells" to establish the locations of the "virtual weather stations." Sophisticated climate models are increasingly able to include details such as clouds, rainfall, evaporation, and sea ice. In my opinion, this would be cherry picking of the worst kind ... HS-ESS2.D4: Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. THE VERY, VERY SIMPLE CLIMATE MODEL. Supercomputers are needed to run large global climate Just as modelers must decide how close together in space to put the "virtual weather stations" at grid intersections, they must also decide how close together in time (that is, "virtual" or "model world" time) to make their calculations. However, if too much "model world" time passes between calculations, the model becomes inaccurate. The Carbon Cycle Game Global climate models (GCMs) use mathematical equations to describe the behavior of factors of the Earth system that impact climate. As a result, there is no way for anyone to make a judgment on the validity of their model. Because the atmosphere is so thin compared to the vast size of our planet, vertical layers are much closer together as compared to the horizontal dimensions of grid cells. except that they did not bother to even show that much data on their plots. What we offer. Higher resolution models provide much more detailed information, but take lots more computing time. In 1990, many climate models used a grid with cells of about 500 km (311 miles) on a side. scroll down to the Details of the Math Behind the Model section. This model will calculate the amount of CO2 in the atmosphere and the average global temperature based on CO2 emissions. The "virtual weather stations" are located at the corners of the grid cells. Weather Research and Forecasting model WRF offers accurate, efficient, high-resolution weather simulation at regional scales and a suite of specialized Earth system capabilities. University Corporation for Atmospheric Research Serving the Earth system science community. The UCAR Center for Science Education develops state-of-the-art educational experiences that connect NCAR|UCAR science including weather, climate, air quality, and the Sun-Earth connection, to diverse learners, creating pathways towards a scientifically literate society. As is the case with spatial resolution, computing-time increases as temporal resolution increases, so if conditions in the model world are calculated too frequently, the model takes a very long time to run. First decide how much CO 2 will be released into the atmosphere each year and set the CO2 emissions rate. … it shows a close correlation between the theory and the actual data. Typical FAR models had a single-layer "slab ocean" and 10 atmospheric layers; AR4 models often include 30 layers in the oceans and another 30 in the atmosphere. Note: The word "assumption" sometimes gets a bad rap. Find out with the Very, Very Simple Climate Model. showing any overlap between the historical and projected temperatures. Global climate models (GCMs) use math to describe how the Earth works. The Temperature vs CO2 plot could be interpreted to show that above 370 ppm, increased CO2 either has no effect, In lesson 6, students use a simple interactive climate model to consider impacts of various scenarios and to develop a strategy for limiting climate change. UCAR provides additional details The guide is very simple, short, and easy for instructors to use while still containing all elements needed to maintain pedagogical effectiveness. > Video: Model Simulation of Past, Present and Future Climate Change, National Center for Atmospheric Research UCAR interactives Modeling The Greenhouse Effect Click here for more detailed instructions about using this model and to view screen shots of sample model runs. Model grids for atmospheric (including climate) models are three dimensional, extending upward through our atmosphere. By 2001, grid cells had, for the most part, been reduced to about 180 km (112 miles), while models run in 2007 typically used a 110 km (68 mile) wide grid cell. is actually about 1.8°C - significantly below Hansen's (presumed) value of 2.713°C/doubling this OpenOffice spreedsheet. The highest resolution examples, T170 and T340, represent future directions in modeling as new, more powerful supercomputers come online in the years ahead. Early climate models typically had about 10 layers vertically; more recent ones often have about 30 layers. I was not very happy with the spreadsheet plots. The main equation used to associate a change in temperature to a change in CO2 The purpose of this page is to present what I learned. A model is often run for several "model years" before the time frame of interest to allow the modeled system to become stable before scientists introduce conditions that alter the system, such as increased levels of carbon dioxide. The T85 resolution is typical for current models. This means that each model run becomes more or less an "if-then" statement such as: "if humans were to act this way, then Earth's climate would warm by this much.". Most computer climate models of climate change: (a) predict the amount of precipitation in the near future. The graphs above show the overlap .. and lack of agreement. Making assumptions about other people can lead to racist/sexist/ageist remarks. As a general rule, increasing the resolution of a model by a factor of two means about ten times as much computing power will be needed (or that the model will take ten times as long to run on the same computer). By the way, the NSTA (National Science Teachers Association) This unit focuses on broad environmental impacts, rather than effects on biodiversity in specific ecosystems. If the model was correct, then the computed temperature (the orange diamonds) CESM is a global climate model for investigating a diverse set of Earth system interactions across multiple time and spatial scales. that CO2 does not affect the temperature in the way the model claims. The Very Simple Climate Model & other Climate Simulations for the Classroom. These are the charts from the spreadsheet. Draw a 2D model. Use your models to communicate your ideas. • CCSS.ELA-Literacy.RST.6-8.4 Determine the meaning of symbols, key terms, and other domain-specific words and The plots were made just to test the accuracy of the model. This model will calculate the amount of CO 2 in the atmosphere and the average global temperature based on CO 2 emissions. Such models will be able to produce projections for regional climates that will be much finer than those we can currently generate. University Corporation for Atmospheric Research, Visit us on Facebook UCAR's Simple Climate Model UCAR's The Very, Very Simple Climate Model (a flash based application) displays a graph of expected future temperatures based on projected CO2 emissions. The basic model below, called the Very Simple Climate Model, gives us a peek into the future. To be clear - their model tacks projected data on to historical data without Are you lost in this alphabet soup yet? Add information to your 2D model. The IPCC deals with uncertain future behaviors of humans by making several different predictions of future climate that assume different amounts of human impact on the climate system in the future. Thousands of climate researchers use global climate models to better understand how global changes such as increasing greenhouses gases or decreasing Arctic sea ice will affect the Earth. Reference issue Meals will not be provided, but participants will … Climate models are run with the scenario assumptions to make predictions. About the Science This resource includes two activities for learning about evaporation and the water cycle. However, I want another 20 years of data before claiming something that radical ... but it is what their A new study takes a detailed look at possible reasons why the latest version of the flagship climate model based at the National Center for Atmospheric Research (NCAR) appears to be “running hot,” projecting an even more pronounced warming response to increased carbon dioxide in the atmosphere than previous versions. on the associated activity page There are four different scenarios used by climate models described in IPCC reports. The fact that I used a different calibration point than the UCAR model (see next section) really has no effect. Add complexities to the simulation. Conclusions Global climate models (GCMs) use math - alot of math - to describe how the atmosphere, the oceans, the land, living things, ice, and energy from the Sun affect each other and Earth's climate. UCAR's flash model can be found via In this model, average global temperature is determined entirely by the atmospheric carbon dioxide concentration via greenhouse warming of the atmosphere. They use worksheets, chips/tokens, and follow rules for heat exchange. Seed Data between CO2 and temperature, assuming the default sensitivity of 3.0°C/doubling. and clicking I found that the best fit uses a base year of 1975 Then I implemented an identical model in The models are used to simulate conditions over hundreds of years, so that we can predict how our planet's climate will likely change. In 1996, resolution had improved by a factor of two, producing grid cells 250 km (155 miles) on a side. Either way, after a failure of this magnitude, all UCAR interactive models must be considered suspect. Thousands of climate researchers use global climate models to better understand the long-term effects of global changes such as increasing greenhouses gases or decreasing Arctic sea ice. In an effort to understand how the model works, To figure out the future of climate change, scientists need tools to measure how Earth responds to change. However, additional analysis using my, This is the temperature provided in the UCAR seed data, This is the temperature computed using A=3°C - the model's default value, This is the temperature computed using A=1°C, You can use it to define future scenarios with various CO2 levels, While the provided historical data starts in 1800, the model's starting year is 1960 - as a result, you can't see how bad the fit-to-theory is, There is no way to plot actual (historical) temperature against values predicted using the supplied CO2 concentrations. doubling of CO2. When using computer models to make predictions about future climate, there are two major sources of uncertainty: Scientific sources of uncertainty are addressed in IPCC reports (see this week's reading about the IPCC) by reporting the findings of many similar, but different, climate models. Find out with the Very, Very Simple Climate Model. and the doubling 6, November–December 2014, pp. These scenarios are a way to make a range of predictions of future climate change based on a range of ways that humans may live, work, and populate the Earth in the future. Models can be generated with higher or lower resolutions. Games & Simulations for Climate Education CLEAN Network Telecon 19 May 2015 Randy Russell UCAR Center for Science Education explore • inspire • engage explore • inspire • engage CMIP (Climate Model Intercomparison Project) Overview The CMIP is a standard experimental framework for studying the output of coupled atmosphere-ocean general circulation models. The main scenario groups are named A1, A2, B1, and B2. That's a lot of calculating... sounds like a job for a supercomputer! Early models (in the 1970s) were relatively simple; they used just a few key features (incoming sunlight, rainfall, and CO 2 concentration) to represent Earth's climate system. These factors include dynamics of the atmosphere, oceans, land surface, living things, and ice, plus energy from the Sun. However, I did find The Cheyenne Supercomputer located at NWSC in Cheyenne, Wyoming. I think it is pretty cool. I was analyzing the model so that I could use the base formula in another program. concentration is the same as the one used by the IPCC and most You suggest the rate that you think humans will release CO 2 into the atmosphere in the future and the model calculates what that means for atmospheric CO 2 concentration and global temperature. And it's very important to be up front about what a particular scientific study assumes and what it tests. The grid cells could be reduced in size to 50 km. In my opinion, .. well, I don't think much of their model. the following equation (from Use caution. Its grid cells are about 100 by 150 km (60 by 90 miles) across at mid-latitudes. (c) predict the effects of humans on temperature, precipitation, and sea level over long periods of time. Prepare a computer with a projector to display the Very, Very Simple Climate model at http://scied.ucar.edu/simple-climate-model Tell students that in this model, average global temperature is determined entirely by the amount of CO 2 in the atmosphere and its effect on temperature (the greenhouse effect). This is the data used to seed the UCAR model. Global climate models (GCMs) use mathematical equations to describe the behavior of factors of the Earth system that impact climate. "A" is known as the "climate sensitivity". The lowest resolution grid shown here, T42, which covers most of the entire state of Florida with just two large grid cells, was typical of model resolution in the mid-1990s. The activity only models temperature but there are instructions for adaptations of the model, such as rule changes for an atmosphere with increased levels of … In this interactive activity students will create a very simple climate model. Credits: Images courtesy of Warren Washington, NCAR. 102 No. UCAR's Model A massive dataset that is widely used by the climate and atmospheric research community to study phenomena like extreme rainfall, ice loss, and extended droughts in North America, is now freely available on the commercial cloud. The Very, Very Simple Climate Model Activity. The other interpretation is that the supplied historical data is wrong - very wrong. Plots While the assumptions behind this model are limited, they are valid. This animation depicts global surface warming as simulated by NCAR's Community Climate System Model (CCSM) Version 3. Visit us on Instagram, Video: Model Simulation of Past, Present and Future Climate Change. Models let you mix up scenarios for how things could be and see what could happen. that computes the forcing (in W/m2). The Very, Very Simple Climate Model What would happen if we released more or less carbon dioxide (CO2) into the atmosphere? All model parameters (temperature, wind speed, humidity, etc.) "Resolution" is an important concept in many types of modeling, including climate modeling. This is the key model statement, GHCN Temperature Plotter to help teach students in grades 6 thru 8 about "climate science". The model shows the temporary cooling effects during 5 major volcanic eruptions and estimates future temperature trends based on And this is the real problem - since the UCAR model starts in 1960, Perform a simulation (working model). A typical climate model might have grid cells with a size of about 100 km (62 miles) on a side. Their default value is 3°C. Introduce the Very, Very Simple Climate model. This material is based upon work supported by the National Center for Atmospheric Research, a major facility sponsored by the National Science Foundation and managed by the University Corporation for Atmospheric Research. Through a simple online model, students learn about the relationship between these and learn about climate modeling while predicting temperature change over the 21st century. Notes on Food & Lodging: There is no cost to attend this workshop. Draw additional 2D models that reflect changes. The starting values for concentration, emission rate, … but the current application does not allow the user to change those values. (To be fair, if I had not found such a blatant discrepancy I probably would not have produced this page. That amount of … I expected poor agreement - but nothing this dramatic. The Equation and in my - select the Background and Extensions tab, Credit: UCAR/Carlye Calvin First, climate scientists at NCAR ran the atmosphere component of a climate model on a supercomputer until it had churned out data for 365 hypothetical days at high resolution, which produced an enormous amount of data– hundreds of gigabytes. The complete lack of agreement is only visible when all the data is used! These are works I have found useful in exploring the world of climate modeling. The Very, Very Simple Climate Model EN Through a simple online model, students learn about the relationship between average global temperature and carbon dioxide emissions while predicting temperature change over the 21st Century. The scenarios are pretty complex, so this is just a broad overview. (b) predict the strength, speed and direction of hurricanes and other threatening weather events. Although we know that traits like temperature vary continuously over the surface of the Earth, calculating such properties for the entire globe is beyond the reach of even the fastest supercomputers. A letter from the UCAR President and the Board of Trustees Read the statement. These diagrams depict the evolution of climate models, and the features included in them, over the years. These are just a few notes about the model. (the UCAR model uses 2000, the spreadsheet uses 1800) Climate models are typically run with time steps of about 30 minutes. At this time, I am not able to find an IPCC equation relating a change in temperature to a change in CO2. Quicklinks. Too difficult to modify the parameters - sensitivity and base year, Not able to compare data with other sources (such as GHCN), Users need to download the data and open it in a spreadsheet to modify the parameters. scientists supporting the CO2 causes Global Warming position. In science, however, assumptions are often critical. and the UCAR model's default of 3°C/doubling. recomends this tools or might actually cause the temperature to decrease. The fact that they aren't even close demonstrates, without a doubt, I have not attempted to verify this data but have simply accepted it as presented. Instead, a climate model places "virtual weather stations" at intervals around the modeled Earth and reports the calculated properties at each station. I used an swf (flash) decompiler to recover the internal model and the seed (historical) data. Spatial resolution specifies how large (in degrees of latitude and longitude or in km or miles) the grid cells in a model are. Statement from UCAR on institutional racism. So the question of how El Niño may change with global warming is a research topic. A climate model run for a century might, therefore, involve 1,753,152 (the number of half-hours in a century) time steps. These factors include dynamics of the atmosphere, oceans, land surface, living things, and ice, plus energy from the Sun. page 52, Table 2.2) Sophisticated climate models are increasingly able to include details such as clouds, rainfall, evaporation, and sea ice. Climate models certainly show changes with global warming, but none simulate El Niño with sufficient fidelity to have confidence in the results. GHCN Temperature Plotter tool. _baselineCO2Concentration and _baselineTemperature can be reset depending on the baseline year, Vertical resolution is not depicted in these images, but has also improved over the years. It is the same data used in the spreadsheet to produce the graphs Temporal resolution refers to the size of the time steps used in models; how often (in simulated or "model time") calculations of the various properties being modeled are conducted. https://scied.ucar.edu/activity/very-simple-climate-model-activity Randy Russell, Lisa Gardiner, Windows to the Universe This is a teaching activity in which students learn about the connection between CO2 emissions, CO2 concentration, and average global temperatures. Vertical layers might be spaced at 11 km intervals as compared to the 100 km intervals for horizontal spacing. It is highly interactive and allows you, the user, to define scenarios combining past, historical data with future emissions of your choice to see how the temperature will change (according to their model). _climateSensitivity can be changed via the, The default temperature and CO2 concentration appear to be near 2000 AD, but don't match any values in the table. UCAR E&O - Randy Russell - Very Simple Climate Model interactive The Very, Very Simple Climate Model This is the most recent version of the "Very, Very Simple Climate Model". This simple model was the first step toward development of complex Earth system models. This would mean fewer grid cells and decreased spatial resolution. Visit us on Twitter Radiative Forcing of Climate Go To: https://scied.ucar.edu/activity/very-simple-climate-model-activity data shows. This would mean that more cells cover Earth's surface, increasing spatial resolution. (By overlap I mean showing both the historical and modeled data should overlap the historical temperatures (the blue squares) 3 | Changing Climate, Changing Cities Teachers’ Guide Common Core Standards: 6th-8th Grade Science and Technical Subjects • CCSS.ELA -Literacy.RST.68.3 Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks. In the UCAR model, the base year is not important since they do not show both they just tack the model results on to the end of the historical data. 422–425. More, smaller cells increases the amount of computing time because there are more "virtual weather stations" at which atmospheric variables must be calculated. In the year 2000, we released 6 Gigatons of CO 2 into the atmosphere. This image is freely available for media & nonprofit use.) . It shows the temperature anomalies relative to the end of the 19th century, both over the entire globe and as a global average. for the same time period on the same plot.) Below are three scenarios. For log-base-2, the value of "A" is the number of degrees-C the temperature changes for a (There are also a few subdivisions of the A1 scenario.) would be calculated at each of the thousands to millions of grid points in the model at each of those time steps. IPCC FAR (1990), Chapter 2, the model results and the historical data for each year - Opportunities. (© UCAR. It has grid cells of about 200 by 300 km (120 by 180 miles) at mid-latitudes. Why Extremes are Important For any change in mean climate, there is likely to be an amplified change in extremes. A table of climate sensitivities (°C) predicted by various models, The U.S. Standard Atmosphere, 1976 document, This analysis demonstrates that the supplied data disproves the association Most of the big unknowns about how Earth's climate will change in the future are due to the fact that we are not sure how humans will change their behaviors in the future. in both plots. Or the grid cells could be enlarged to 200 km. This facilitates assessment of the strengthsand weaknesses of climate models which can enhance and focus the development of future models.
