By Leo Hickman, James Randerson The computer files were apparently accessed earlier this week from servers at the University of East Anglia's Climate Research Unit, a world-renowned centre focused on the study of natural and anthropogenic climate change. In another alleged email, one of the scientists apparently r...

By JR(jonjayray@gmail.com) Just recently, as scientists who specialize in environmental science, climatology, and solar variability, we welcomed the acceptance of our scientific session, Diverse Views from Galileo’s Window: Researching Factors and Processes of Climate Change in the Age of Anthropogenic C...

By Nature Authors: S. Khatiwala, F. Primeau & T. Hall The release of fossil fuel CO2 to the atmosphere by human activity has been implicated as the predominant cause of recent global climate change. The ocean plays a crucial role in mitigating the effects of this perturbation to the climate system...

By JR(jonjayray@gmail.com) At issue is whether humans are, or are not, affecting changes to the Earth's temperature that have always happened naturally. The AGW-hypothesis says increased greenhouse gases – notably carbon dioxide – in the air raise global temperature and anthropogenic emissions are increasing...

By JR(jonjayray@gmail.com) References Abstract: Global mean temperature at the Earth's surface responds both to externally imposed forcings, such as those arising from anthropogenic greenhouse gases, as well as to natural modes of variability internal to the climate system. Variability associated with thes...

By JR(jonjayray@gmail.com) In 2004 the UN climate panel that carbon dioxide accounted for 76 percent of the anthropogenic emissions of greenhouse gases. Newly released UNEP report which showed that emissions other than carbon dioxide plant accounted for half of emissions, this is not an example of scientific unc...

By Roger Pielke Sr. 2. A coordinated research effort is required to address the multidimensionality of climate change, including the role of LUCC and its dynamic interaction with increased concentrations of anthropogenic greenhouse gases. This requires evaluating: (i) the capacity of reforestation t...

By Roger Pielke Sr. We both agree that land use change is a first-order climate forcing on the local scale;We both agree that in terms of the global average radiative imbalance, that land use change, so far, has been less than that caused by the anthropogenic addition of the well-mixed greenhouse gases and...

By Roger Pielke Sr. “Earth’s climate is a complex dynamical system that is responding to an array of forcings, which include anthropogenic carbon dioxide and aerosols and solar variability. Aeorsol and solar forcings are imperfectly constrained and only monitored by observational systems with limite...

By Roger Pielke Sr. “In order to understand the solar influence on climate and the atmosphere, it is essential to also understand the contributions of volcanic aerosols, as well as anthropogenic greenhouse gases and tropospheric aerosols, and other human influences such as land use changes, all of whic...

By Mike Millikin A special report in 1999 by the UN’s IPCC on aviation and climate change calculated that emissions of carbon dioxide by aircraft were 0.14 Gt C/year in 1992. This was about 2% of total anthropogenic carbon dioxide emissions in 1992 or about 13% of carbon dioxide emissions from all transport...
