Future Climate Depends on Us
What is One Million Metric Ton of Carbon Dioxide-Equivalent?
The amount of greenhouse gases emitted into the atmosphere from U.S. landfills in 2007 was equivalent to more than 132 million metric tons of carbon dioxide, or MMtCO2-e, according to U.S.
Reducing Greenhouse Gases from Cars and Commercial Vehicles
Transportation is responsible for a large portion of all greenhouse gases emitted in the Southwest region. It is also a significant source of other air pollutants that impact human health, including particulate matter and others that contribute to ground-level ozone. Approximately 23 percent of all greenhouse gases emitted in the U.S.
Annual Meeting of the Western Governors' Association
June 14, 2009 - June 16, 2009 | Park City, Utah | Event Web site
This year's meeting will focus on developing regional and global strategies for addressing the intertwined issues of energy, climate change and water. Join us and officials from the Obama Administration, international dignitaries and a host of private and public-sector leaders from around the West.
Greenhouse 2009: Climate Change and Resources
March 23, 2009 - March 26, 2009 | Perth, Western Australia | Event Web site
CSIRO, in conjunction with the Australian Climate Change Science Program, is proud to announce GREENHOUSE 2009: Climate Change and Resources. The conference is the latest in the 'GREENHOUSE' series, following the highly-successful events in 2007 in Sydney, and 2005 in Melbourne.
First International Greenhouse Gas Measurement Symposium
March 22, 2009 - March 25, 2009 | Burlingame, California | Event Web site
Reducing greenhouse gas (GHG) emissions to alleviate harmful effects of climate change is one of the greatest challenges of our time.
Navigating the American Carbon World
April 2, 2009 - April 3, 2009 | San Diego, California | Event Web site
In a landmark partnership, the organizers and co-organizers of the world’s three leading climate events in 2008 bring you the premier carbon conference and trade fair in North America in 2009. Together, these three organizations bring you a carbon conference and trade fair with a combined expertise, depth and industry involvement unrivaled among any other carbon market event.
CO2 Concentrations and Temperature Have Tracked Closely Over the Last 300,000 Years
As ice core records from Vostok, Antarctica show, the temperature near the South Pole has varied by more than 20º F during the past 350,000 years in a regular pattern that constitutes the ice age/interglacial cycles.
Positive and Negative Feedback Cycles
Feedbacks are important drivers of climate change as well as sources of uncertainty for projected changes.
Greenhouse Effect
The greenhouse gas effect functions by trapping in the atmosphere heat from the Sun’s radiation. The greenhouse gases can be thought of as creating a one-way mirror—they allow the short wavelength energy emitted by the Sun to pass through the atmosphere and warm the Earth’s surface, but they do not allow all the longer wavelength energy radiated by the Earth back to space.
