The stadium wave

by Judith Curry This paper will change the way you think about natural internal variability.

Week in review – science edition

by Judith Curry A few things that caught my eye this past week.

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.

Looking forward to 2018

by Judith Curry Happy New Year everyone!  My ‘prognostications’, hopes and goals for 2018.

Will the Oroville Dam survive the ARkStorm?

by David Hagen Should California plan for permanent drought or climate persistence?

Prospects for a Prolonged Slowdown in Global Warming in the Early 21st Century

by Nic Lewis [W]e estimate that the warming slowdown (< 0.1 K/decade trend beginning in 1998) could persist, due to internal variability cooling, through 2020, 2025 or 2030 with probabilities 16%, 11%, and 6%, respectively. – Knutson et al.

Arctic winter sea ice puzzle

by Judith Curry Arctic sea ice extent has been anomalously low this winter.

Has the intrinsic component of multidecadal climate variability been isolated?

by Sergey Kravtsov, Marcia Wyatt, Judith Curry and Anastasios Tsonis A discussion of two recent papers: Steinman et al. (2015) and Kravtsov et al. (2015)

400(?) years of warming

by Judith Curry So, exactly how long has it been warming?

A perspective on uncertainty and climate science

by Marcia Wyatt This past summer I was asked to give a presentation on science and ethics. The person who asked me was motivated by the Pope’s encyclical, the comments regarding climate change.

Why is the Arctic climate and ice cover so variable?

by Judith Curry A discussion of Section 8.3 of Alan Longhurst’s book Doubt and Certainty in Climate Science.

Has the AMO flipped to the cool phase?

by Judith Curry Klotzbach and Gray ask whether the active Atlantic hurricane era has ended, owing to the negative values of the AMO.

Hurricanes and global warming: 10 years post Katrina

by Judith Curry We anticipate that it may take a decade for the observations to clarify the situation as to whether the hypothesis has predictive power. – Curry et al. 2006

Impact of AMO/PDO on U.S. regional surface temperatures

by Judith Curry The conclusion is that the oscillatory mode (mostly due to the AMO) is significantly more important than the monotonic mode (mostly due to increasing atmospheric CO2) in explaining the 1980–2000 U.S. temperature increase.  – Bruce Kurtz

Quantifying the anthropogenic contribution to atmospheric CO2

by Fred Haynie I conclude that, the IPCC’s model assumptions that long-term natural net rate of accumulation is constant and anthropogenic emission rates are the only contributor to total long-term accumulation of atmospheric CO2, is false.

Whats up with the Atlantic?

by Judith Curry The Washington Post has this dramatic headline:  Global warming is now slowing down the circulation of the ocean with potentially dire consequences.

2 new papers on the ‘pause’

by Judith Curry Two new papers were published last week of relevance to the hiatus.

Will a return of rising temperatures validate the climate models?

by Donald C. Morton The coincidence of the current plateau in global surface temperatures with the continuing rise in the atmospheric concentration of carbon dioxide has raised many questions about the climate models and their forecasts of serious anthropogenic global … Continue reading

New presentations on sea ice

by Judith Curry I have prepared two new talks on sea ice to present in Nanjing.

Two contrasting views of multidecadal climate variability in the 20th century

by Judith Curry Our new stadium wave paper is now published.

The 50-50 argument

by Judith Curry Pick one: a)  Warming since 1950 is predominantly (more than 50%)  caused by humans. b)  Warming since 1950 is predominantly caused by natural processes.

Cause of hiatus found deep in the Atlantic Ocean

by Judith Curry Rapid warming in the last three decades of the 20th century, they found, was roughly half due to global warming and half to the natural Atlantic Ocean cycle that kept more heat near the surface. When observations … Continue reading
