Reflections on energy blogging

by Planning Engineer Five years ago today I started guest blogging on Climate Etc., focusing on energy related issues.

Year in review – Climate Etc.’s greatest ‘hits’

by Judith Curry 2016 was ‘extremely likely’ to have been a memorable year.

A beneficial climate change hypothesis

by Rud Istvan A novel hypothesis on the role of CO2 in the technological transition from hunter/gatherers to sedentary agriculture.

2015 → 2016

Sea level rise, acceleration and the closure problem

by Rud Istvan There is no doubt that interglacials change sea level (SL). And that sea level rise (SLR) can be dramatic on millennial interglacial time scales.

Another Antarctic Sea Level Rise False Alarm

by Rud Istvan Aitken et. al. in Nature newly comports to confirm 2015 fears about instability of the Totten Glacier in Eastern Antarctica. This could ‘suddenly’ raise sea level as much as 4 meters! (Or, based on the abstract, maybe … Continue reading

Energy strategies: horses for courses

by Planning Engineer and Rud Istvan Just because something works in one place’s circumstances does not mean it will work elsewhere under different circumstances.   

Vehicular decarbonisation – two new technologies to watch

by Rud Istvan This post addresses issues related to  ‘vehicular decarbonization’. It is  an energy storage insider’s narrative of how tough a slog developing some of the requisite applied science technologies has been over the past decades. It is a … Continue reading

Modeling Lindzen’s adaptive infrared iris

by Rud Istvan In 2001, MIT’s Professor Richard Lindzen and colleagues published a controversial  paper titled “Does the Earth have an Adaptive Infrared Iris?” [1] If there were a tropical adaptive infrared iris, then Earth’s sensitivity to GHGs would be … Continue reading

JC’s book shelf

by Judith Curry Some new books that I’ve been reading, by  Roger Pielke Jr., Rud Istvan, George Marshall and James Gleick.

Lessons from the ‘Irreducibly Simple’ kerfuffle

by Rud Istvan UPDATE:  Response from Christopher Monckton The Monckton, Soon, Legates, and Briggs paper “Why models run hot, results from an irreducibly simple climate model” appeared in the January 2015 Science Bulletin of the Chinese Academy of Sciences (CAS). … Continue reading

Observational support for Lindzen’s iris hypothesis

by Judith Curry  It’s nice to see that our ‘discredited’ theory doesn’t seem to go away. – Richard Lindzen

Microgrids and “Clean” Energy

by Planning Engineer and Rud Istvan Microgrids and “clean” energy are intertwined in the minds of many. There is a common belief that microgrids will facilitate “clean” energy and that “clean” energy will better support microgrids.

2014 → 2015

by Judith Curry Before ringing in the New Year, its time to reflect on 2014.

Intermittent grid storage

by Rud Istvan From the utility grid perspective, a fundamental problem with wind and solar is intermittency.

Solar grid parity?

by Rud Istvan and Planning Engineer                                                  There are many journal articles, media stories, NGO papers, and blogs … Continue reading

Public intellectuals in the climate space

by Judith Curry Wanted: disruptive ideas on climate change.

NCDC responds to concerns about surface temperature data set

Our algorithm is working as designed. – NOAA NCDC

Clean(?) Coal

by Rud Istvan Many climate policy debates come down to coal as an electricity fuel, including the EPA’s proposed coal power plant CO2 regulations.

True costs of wind electricity

by Planning Engineer and Rud Istvan  Wind turbines have become a familiar sight in many countries as a favorite CAGW mitigation means. Since at least 2010, the US Energy Information Agency (EIA) has been assuring NGOs and the public that … Continue reading

Sea level rise tipping points

by Rud Istvan Sea level tipping points are a popular CAGW/media theory, easily suggested by images of calving icebergs and summer meltwater rushing down Greenland moulins. But they are alarmist precautionary mitigation fantasies rather than remotely possible future scenarios on multi-centennial … Continue reading

More scientific mavericks needed

by Judith Curry Mavericks once played an essential role in research. Indeed, their work defined the 20th century.

No bodies

by Rud Istvan One of the firmer catastrophic anthropogenic global warming (CAGW) predictions made by IPCC AR4 WG2 was an alarming increase in species extinctions.

Ice sheet collapse?

by Rud Istvan One of the catastrophes associated with anthropogenic global warming (CAGW) is a rising sea.     Is the projected rise and rate unprecedented? Will it be catastrophic?                           … Continue reading

When bad news is good

by Rud Istvan The crescendo of climate change ‘bad’ news leading up to release of problematic AR5 SPM continues.
