Its construction now complete, the science instrument that is the heart of NASA's Orbiting Carbon Observatory-2 (OCO-2) spacecraft -- NASA's first mission dedicated to studying atmospheric carbon dioxide -- has left its nest at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and has arrived at its integration and test site in Gilbert, Ariz.

"Q&A: carbon capture and storage How does it work, which countries are leading technological developments, and what is the future for CCS?"

"A carbon footprint is an estimate of the climate change impact of activity - such as making a product, living a lifestyle or running a company."

Graphic representation of current, per capita, cumulative, and intensity of carbon emissions

"Time history of atmospheric carbon dioxide from 800,000 years ago until January, 2012." excellent animation

Climate scientists have long argued that ancient air trapped in Antarctic ice is the smoking gun that links carbon dioxide to global warming. Over the past 800,000 years or so the planet has gone through a series of ice ages interspersed with relatively warm periods (during which glaciers retreat back toward the poles) - and inevitably, these warm interludes happen when there's more CO2 in the atmosphere

"Carbon Brief reports on the latest developments in climate science, and fact-checks stories about climate and energy online and in the press. We provide briefings on the people and organisations talking about climate change, and we produce background materials on science issues and news stories."

Carbon counter shows the metric tons of greenhouse gases in the atmosphere.

"Earth's climate is stable within limits. After small changes in temperature, the climate will remain stable, but larger changes can be dangerous....... Your task is to explore different scenarios with our Carbon/Temperature Model do draw some conclusions about what events are causing the greatest shifts."

At TED2010, Bill Gates unveils his vision for the world's energy future, describing the need for "miracles" to avoid planetary catastrophe and explaining why he's backing a dramatically different type of nuclear reactor. The necessary goal? Zero carbon emissions globally by 2050

"The Arctic experienced an extended period of warm temperatures about 3.6 million years ago - before the onset of the ice ages - at a time when the concentration of carbon dioxide in Earth's atmosphere was not much higher than the levels being recorded today, a new study finds."

from the Post Carbon Institute: 'Ever wondered how to efficiently talk to folks who say we have PLENTY of fossil fuels to extract? Here's a highly informative piece. AlterNet's great Tara Lohan talks to Richard Heinberg about this and much more.'

CarbonTracker, a project of the U.S. government's National Oceanic & Atmospheric Administration's Earth System Research Laboratory, has produced a telling time-lapse video chart of CO2 (Carbon Dioxide) concentrations starting in January of 1979 and ending in January of 2011. Measurements were taken in dozens of locations around the world (the red ball measures CO2 in Hawaii and the blue dot measures CO2 at the South Pole)

some very interesting materials from UC Berkeley. A neat carbon footprint calculator, good articles, and generally useful reading.
