Venus: Runaway Greenhouse Effect Very thick atmosphere, mostly CO 2 High temps of almost 480°C (900°F) –Hotter than Mercury Source: solarsystem.nasa.gov/planets/profile.cfm?Object=Venus My Very Excellent Mother Just Served Us Noodles

Humans & Greenhouse Gases Humans produce more carbon dioxide (CO 2 ) than any other greenhouse gas Source: Global Greenhouse Gas Emissions by Gas

How do humans release CO 2 ? Electricity Largest source of CO 2 emissions in U.S. Transportation Industry Source: U.S. Carbon Dioxide Emissions, By Source

Climate Description of the long-term pattern of weather in a particular area –Today’s (or even this month’s or this year’s) weather is NOT the same as climate Source:

Climate Change Refers to any significant change in the measures of climate lasting for an extended period of time Global warming –Temperature increasing Precipitation patterns More severe storms Source:

Global Warming Source: earthobservatory.nasa.gov/Features/GlobalWarming/page2.phpv Recorded Data Since 1880

Atmospheric CO 2 and Temperature: What is the Relationship?

Global Temperature Projections Source: global-temperature-projections The graph shows the average of a set of temperature simulations for the 20th century (black line), followed by projected temperatures for the 21st century based on a range of emissions scenarios (colored lines). The shaded areas around each line indicate the statistical spread (one standard deviation) provided by individual model runs.
