  • Economic Efficiency of Fossil Fuel Usage

    style/images/uploads/Fossil_Fuel_Efficiency.png

    The bar graph illustrates how efficiently the world’s 20 largest economies convert fossil fuel usage into a measure of wealth (their gross national product). Here, the measure is purchasing power in U.S. dollars over the number of kilograms of fossil fuel carbon released into the atmosphere each year. The two countries that produce the highest GDP per kilogram carbon, Brazil and France, rely much more on the alternative energy sources of hydroelectric power and nuclear power than other countries.

  • Urban Heat Islands

    http://eoimages.gsfc.nasa.gov/images/imagerecords/47000/47704/buffalo_etm_2002215.jpg

    By evaporating water, plants cool their surroundings. By replacing plants with impervious surfaces, cities trap heat and create a phenomenon known as the urban heat island. A variety of factors affect the urban heat island. Bigger cities tend to have stronger heat-trapping capacities than smaller cites. Cities surrounded by forest have more pronounced heat islands than do cities in arid environments. A study presented at the 2010 fall meeting of the American Geophysical Union found that a city’s layout—whether sprawling or compact—can also affect the potency of its urban heat island.
     
    This image shows Buffalo, NY, on Aug. 3, 2002. Acquired by the Enhanced Thematic Mapper on NASA’s Landsat 7 satellite, they show temperature, ranging from blue (warm) to beige (hot). White lines delineate city limits. The researchers found that Buffalo has surface temperatures just 7.2 degrees Celsius (almost 13 degrees Fahrenheit) warmer than its surroundings.

  • Earth Now: Air Temperature

    style/images/uploads/ete1.jpg

    NASA's Earth Now is an application that visualizes recent global climate data from Earth science satellites, including surface air temperature, carbon dioxide, carbon monoxide, ozone, and water vapor as well as gravity and sea level variations. Data sets are visually described using "false color" maps. Color-coded legends are provided to indicate relative strength or weakness of an environmental condition. The resulting 3D model of the Earth may be rotated by a single finger stroke and may also be zoomed in or out by pinching two fingers. It was developed by the Earth Science Communications and Visualization Technology Applications and Development Teams at NASA's Jet Propulsion Laboratory, with support from NASA headquarters.

    The graph shows the predicted temperature change because of global climate change as issued by the Hadley Centre climate model. The colors show predicted average temperature changes for 2070-2100. Notice the distinct warming difference between land and water. The strong warming around the Arctic Ocean is related to melting sea ice, and the strong warming in South America is related to El Nino cycles. (Models differ according to variables considered.)

    The Global Historical Climatology Network is a primary reference for temperature data used for climatology research. This map shows 7,280 temperature stations coded by years of data records. “Active” sites update the database; historical sites have collected data but do not contribute to current data. The United States is the most densely instrumented region of the globe; Antarctica is the least. The longest record in the network collection began in Berlin in 1701 and continues to the present.

    Data sets from the Emission Database for Global Atmospheric Research, version 3.2, Fast Track 2000 project. Use the top graphic to find out the sources and amounts for the greenhouse gases shown in the graphics at the bottom. For example, looking at carbon dioxide, 29.5% of the emissions (shown in red) come from power stations, and 19.2% of carbon dioxide emissions come from transportation fuels (as shown in gold).

    Annual Greenhouse Gas Emissions by Sector
  • Carbon Dioxide Variations

    style/images/uploads/Carbon_Dioxide_400kyr_Rev.png

    Scientists have drilled deep cores through the icecap in Antarctica. Measurements of CO2 captured in annual ice deposits in the cores allow scientists to reconstruct atmospheric CO2 variations over the last 400,000 years. 
    Notice the large variations in concentrations every 100,000 years. This occurs because of periodic changes in Earth's orbit.
    Notice the additional graph inserted within the larger graph.  This shows that CO2 abundance has increased steadily since the Industrial Revolution started in the 1700s and in the last 100 years has increased from about 275 parts per million (ppm) to about 375 ppm. This new high is greater than any CO2 measurement from the last 400,000 years. Is this evidence for natural CO2 variation or human-caused variation? Is there evidence for natural variation in these data?

    Carbon Dioxide Variations
  • Global Trends in Major Greenhouse Gases to 1/2003

    style/images/uploads/Major_greenhouse_gas_trends.png

    The rise in greenhouse gas concentrations are believed to cause most of the increase in global temperatures during the last 50 years.
