New Paper: Estimated Warming Due to CO2 Cut by 65%?

In “Short-lived uncertainty?” Joyce E. Penner et al.  note that several short-lived atmospheric pollutants—such as methane, tropospheric ozone precursors and black-carbon aerosols—contribute to atmospheric warming while others, particularly scattering aerosols, cool the climate. Figuring out exactly how great the impacts of these other forcings are can radically change the way historical climate change is interpreted. [...]

Earth’s ‘Ancient’ Climate Similar to Today, Despite 5 to 20 Times Higher CO2 Levels

An international team of scientists including Mark Williams and Jan Zalasiewicz of the Geology Department of the University of Leicester, and led by Dr. Thijs Vandenbroucke, formerly of Leicester and now at the University of Lille 1 (France), has reconstructed the Earth’s climate belts of the late Ordovician Period, between 460 and 445 million years [...]

Climate Feedbacks: Comment/Reply Avoided at Journal of Climate

Roy Spencer writes on his blog: It is unfortunate that the authors and/or an editor at Journal of Climate decided that Murphy & Forster 2010 (MF10) would be published without asking me or Danny Braswell to be reviewers. Their paper is quite brief, and is obviously in the class of a “Comments on…” paper, yet [...]

Nature Paper: Greenhouse Effect is Temporary

Hebrew University Scientists publish study in Nature: ‘AGW is refuted’ — ‘Claims that carbon emissions permanently increase global temperature are false’ Abstract; We use statistical methods designed for nonstationary time series to test the anthropogenic theory of global warming (AGW). This theory predicts that an increase in atmospheric greenhouse gas concentrations increases global temperature permanently. [...]

New Study: Sea Level 1 Meter Higher, CO2 Lower 81,000 Years Ago

A new study has been published in the journal Science: Sea-Level Highstand 81,000 Years Ago in Mallorca Jeffrey A. Dorale,1,* Bogdan P. Onac,2,* Joan J. Fornós,3 Joaquin Ginés,3 Angel Ginés,3 Paola Tuccimei,4 David W. Peate1 Abstract: Global sea level and Earth’s climate are closely linked. Using speleothem encrustations from coastal caves on the island of [...]

New Study: Water Vapour a Major Cause of Warming and Cooling

American researchers have discovered that the amount of water high in the atmosphere is far more influential on world temperatures than previously thought. The study, published in the journal Science, says a 10 per cent drop in humidity 10 miles above the Earth’s surface explains why global temperatures have been stable since the start of [...]

New Study Suggests CO2 Feedback is 80% Weaker Than Expected

The authors of a new paper published in the journal Nature entitled: ‘Ensemble reconstruction constraints on the global carbon cycle sensitivity to climate’ have analysed the variations in the climate from AD 1050 – 1800 in order to estimate the influence of temperature change on the concentration of CO2 in the atmosphere. Other scientists have suggested [...]

Over 60% of Expected Industrial Era Greenhouse Warming is Missing

UPTON, NY – Planet Earth has warmed much less than expected during the industrial era based on current best estimates of Earth’s “climate sensitivity”—the amount of global temperature increase expected in response to a given rise in atmospheric concentrations of carbon dioxide (CO2). In a study to be published in the Journal of Climate, a [...]

Revisiting Miskolczi’s Saturated Greenhouse Effect Theory

Dr. Miskolczi first published his work in the Quarterly Journal of the Hungarian Meteorological Services in 2004, Volume 108, No 4. He published further statistical proof in the same Journal in 2007, Volume 111, No. 1. In the 5 years since he first published his results, not one peer review has come back disproving his [...]

Finnish TV: Climate Catastrophe Cancelled

Finnish TV have interviewed Steve McIntyre and Richard Lindzen about their work on climate change. The programme provides an excellent summary of the Hockey Stick controversy and Lindzen’s recent climate sensitivity paper. The transcript in English is here.
