CO2 diffusion in polar ice: observations from naturally formed CO2 spikes in the Siple Dome (Antarctica) ice core

Jinho AHN, Melissa HEADLY, Martin WAHLEN, Edward J. BROOK, Paul A. MAYEWSKI, Kendrick C. TAYLOR ABSTRACT. One common assumption in interpreting ice-core CO2 records is that diffusion in the ice does not affect the concentration profile. However, this assumption remains untested because the extremely small CO2 diffusion coefficient in ice has not been accurately determined in the laboratory. In this study we take advantage of high levels of CO2 associated with refrozen layers in an ice core from Siple Dome, Antarctica, to study CO2 diffusion rates. We use noble gases (Xe /Ar and Kr /Ar), electrical conductivity and Ca2+ ion …

Q&A: IPCC wraps up its most in-depth assessment of climate change

carbonbrief.org March 23, 2023 The final part of the world’s most comprehensive assessment of climate change – which details the “unequivocal” role of humans, its impacts on “every region” of the world and what must be done to solve it – has now been published in full by the UN’s Intergovernmental Panel on Climate Change (IPCC). The synthesis report is the last in the IPCC’s sixth assessment cycle, which has involved 700 scientists in 91 countries. Overall, the full cycle of reports has taken eight years to complete. The report sets out in the clearest and most evidenced detail yet …

Environmentalists Petition EPA to Ban Natural Gas Use in Buildings

Environmentalists Petition EPA to Ban Natural Gas Use in Buildings

Master Resource By Mark Krebs | September 9, 2022 “The environmentalists have been emboldened by their ‘win’ with the passage of the IRA. Never satisfied, their petition is one of the first attempts to expand it.” It never ends…. In the wake of the 725-page “Inflation Reduction Act” (IRA), consumer choice for energy could be intentionally restricted to electricity by the U.S. Environmental Protection Agency (EPA). Or at least that seems to be the plan. According to a petition submitted by environmentalists, EPA should regulate carbon dioxide (CO2) emissions resulting from using natural gas in homes and businesses. The eco-lobby has …

The New Pause Pauses

The New Pause Pauses

By Christopher Monckton of Brenchley| Sept. 3, 2022 The New Pause has paused. As in July, so in August, there has been a zero trend in global warming for 7 years 11 months according to the UAH satellite lower-troposphere dataset – For completeness, here is the whole dataset since it went live in December 1978 – Woe, woe and thrice woe! [Britain has had Mediterranean weather, and we like it, which is why we holiday there: I am about to give a piano recital in Malta]. Lake Mead is drying up!! [through over-extraction, not global warming]. The whole of Europe, …

Follow the (Climate Change) Money

Follow the (Climate Change) Money

Principia Scientific | September 22, 2019 Written by Stephen Moore The first iron rule of American politics is: Follow the money. This explains, oh, about 80 percent of what goes on in Washington. Shortly after the latest “Chicken Little” climate change report was published last month, I noted on CNN that one reason so many hundreds of scientists are persuaded that the sky is falling is that they are paid handsomely to do so. I said, “In America and around the globe governments have created a multibillion dollar climate change industrial complex.” And then I added: “A lot of people …
