Hurricanes & climate change: 21st century projections

by Judith Curry Final installment in my series on hurricanes and climate change.

Hurricanes & climate change: recent U.S. landfalling hurricanes

by Judith Curry An assessment of whether any of the impacts of recent  U.S. landfalling hurricanes were exacerbated by global warming.

Critique of the new Santer et al. (2019) paper

by Ross McKitrick Ben Santer et al. have a new paper out in Nature Climate Change arguing that with 40 years of satellite data available they can detect the anthropogenic influence in the mid-troposphere at a 5-sigma level of confidence. … Continue reading

Hurricanes and Climate Change: Attribution

by Judith Curry Part II:  what causes variations and changes in hurricane activity?

Hurricanes & climate change: detection

by Judith Curry I am preparing a new Special Report on Hurricanes and Climate Change.

Is ocean warming accelerating faster than thought?

by Nic Lewis *** UPDATE : response to comments by Zeke Hausfather appended There are a number of statements in Cheng et al. (2019) ‘How fast are the oceans warming’, (‘the paper’) that appear to be mistaken and/or potentially misleading. … Continue reading

Ocean Heat Content Surprises

by Judith Curry There have several interesting papers on ocean heat content published in recent weeks, with some very important implications.

Special Report on Sea Level Rise

by Judith Curry I have now completed my assessment of sea level rise and climate change.

Hurricane Florence: climate dynamics context

by Judith Curry “Impending massive hurricanes bring the best out of weather twitter and the worst out of climate twitter” – Joseph Maykut

A Test of the Tropical 200-300 mb Warming Rate in Climate Models

by Ross McKitrick I sat down to write a description of my new paper with John Christy, but when I looked up a reference via Google Scholar something odd cropped up that requires a brief digression.

Nature Unbound X – The next glaciation

by Javier Summary: The IPCC expresses virtual certainty that a glaciation is not possible for the next 50 Kyr if CO2levels remain above 300 ppm. It is the long interglacial hypothesis. Analysis of interglacials of the past 800 Kyr shows … Continue reading

Nature Unbound IX – 21st Century Climate Change

by Javier A conservative outlook on 21st century climate change

Sea level rise acceleration (or not): Part VII U.S. coastal impacts

by Judith Curry The final installment in the CE series on sea level rise.

Sea level rise acceleration (or not): Part IV – Satellite era record

by Judith Curry Part IV of the Climate Etc. series on sea level rise focuses on the satellite era (since 1993), including the recent causes of sea level variations and arguments regarding the acceleration (or not) of recent sea level … Continue reading

Sea level rise acceleration (or not): Part II – The geological record

By Judith Curry Part II of the Climate Etc. series on sea level rise –the geological record provides context for the recent sea level rise.

Nature Unbound VII – Climate change mechanisms

by Javier Climate variations that alter the angular momentum of the atmosphere modify the speed of the Earth’s rotation, which affects the length of day (LOD). Alterations in LOD integrate different climate-affecting phenomena, and can anticipate turning points in climate.

Nature Unbound V – The elusive 1500-year Holocene cycle

by Javier The existence of a 1500-year climatic cycle during the Holocene, related to the glacial Dansgaard-Oeschger cycle, is a matter of intense debate. However, by introducing precise timing requirements it can be shown that the 1500-year cycle displayed in … Continue reading

Nature Unbound IV – The 2400-year Bray cycle. Part B

by Javier In Part A, we established the existence of a ~ 2400-year climate cycle, discovered in 1968 by Roger Bray. This climate cycle correlates in period and phase with a ~ 2400-year cycle in the production of cosmogenic isotopes, … Continue reading

Framing the challenge for the climate red team

by Judith Curry There is an opportunity to steer the proposed red team exercise in a useful direction.  The first step is to frame the problem to be addressed.

Does a new paper really reconcile instrumental and model-based climate sensitivity estimates?

by Nic Lewis A new paper in Science Advances by Cristian Proistosescu and Peter Huybers (hereafter PH17) claims that accounting for the decline in feedback strength over time that occurs in most CMIP5 coupled global climate models (GCMs), brings observationally-based … Continue reading

National Climate Assessment and the Trump administration

The National Climate Assessment must be redirected or terminated by Patrick J. Michaels Periodic National Assessments of the effects of climate change on the U.S. are mandated by the 1990 Global Change Research Act. The next Assessment Report is scheduled to … Continue reading
