Carbon Dioxide Rich Atmosphere in an Ancient Ice Age

Research by the University of Birmingham has provided evidence that a warm atmosphere rich in carbon dioxide was present in an ancient ice age.  This could only have happened if the planet was nearly all covered in ice and snow. Scientists from the University’s School of Geography, Earth and Environmental Sciences, say that, whereas today, [...]

NASA’s Orbiting Carbon Observatory (OCO)

The US space agency is set to launch a satellite that can map in detail where carbon dioxide is in the atmosphere. Nasa’s Orbiting Carbon Observatory (OCO) will pinpoint the key locations on the Earth’s surface where CO2 is being emitted and absorbed….. However, to locate the sources and sinks, scientists will need to combine [...]

EU Parliament Passes New Car CO2 Legislation

Average CO2 emissions from new cars must be slashed to 130g/km by 2015, the equivalent of achieving 58mpg with a diesel engine and 52mpg in a petrol car. The EU new car CO2 legislation passed by the European parliament today sets out a tough programme for car manufacturers with 65% of new cars averaging the [...]

A Role for Atmospheric CO2 in Preindustrial Climate Forcing?

An interesting new paper has been published in PNAS that relies on modelling of climate forcing by CO2, and stomatal index as a proxy for atmospheric CO2 levels. This supports the doubts cast by a minority of scientists on the accuracy of atmospheric CO2 data derived from ice cores. The paper is entitled: A role for atmospheric [...]

CO2 and Climate During the Last Glacial Period

A new paper has been published in Science magazine entitled: ‘Atmospheric CO2 and Climate on Millennial Time Scales During the Last Glacial Period,’ by Jinho Ahn and Edward J. Brook. The Abstract states: Reconstructions of ancient atmospheric carbon dioxide (CO2) variations help us better understand how the global carbon cycle and climate are linked. We [...]

China Top CO2 Emitter, India Closes in on 3rd Place

According to a new report from the research consortium Global Carbon Project (GCP), the biggest increase in CO2 emissions has taken place in developing countries, largely in China and India, while developed countries have been growing slowly. The largest regional shift was that China passed the U.S. in 2006 to become the largest CO2 emitter, [...]

Limits on CO2 Climate Forcing from Recent Temperature Data

David Douglass and John Christy have a new paper accepted in the refereed section of the journal Energy & Environment, which is also available as an arXiv pre-print.  It’s unusual for either John Christy or David Douglass to submit a paper to E & E, which doesn’t appear in any citation index. On the other hand, [...]

Past Climate Implies Higher Atmospheric Carbon Dioxide Levels in the Future

A new perspective has been published in the journal Science entitled: ‘Illuminating the Modern Dance of Climate and CO2.’ The paper states: Climate and atmospheric carbon dioxide (CO2) concentrations have been coupled through much of Earth’s history: CO2 influences climate through the greenhouse effect, but climate also influences CO2 through its impact on the stores of [...]
