Environmental Justice campaign to replace New York City peaking power plants

Posted on April 2, 2021 by | 112 comments

by Roger Caiazza

Environmental justice organizations are currently a major driver of environmental regulation in New York. A new report “The Fossil Fuel End Game, A frontline vision to retire New York City’s peaker plants by 2030” illustrates the campaign strategy they are using to shut down peaking power plants in New York City.  Unfortunately their claims are based more on emotion than fact.

A pertinent climate question

Posted on March 28, 2021 by | 120 comments

by Michel de Rougemont

Not so innocent as it looks, a pertinent question is asked by Judith Curry on Twitter:

How much of a change in cloudiness would it take to account for the 0.53 W/m2 increase in TOA radiative forcing since 2003?

Compensation between cloud feedback + ECS and aerosol-cloud forcing in CMIP6 models

Posted on March 5, 2021 by | 45 comments

By Nic Lewis

An important paper, Wang et al.[1], on the relationships between cloud feedback, climate sensitivity (ECS) and aerosol-cloud interaction in the latest generation of global climate models (CMIP6) has just been published. The key conclusion of the paper is:

The seeming consistency of global-mean temperature evolution between more positive cloud feedback (high ECS) models and observations requires a strong aerosol indirect cooling effect that leads to an interhemispheric temperature evolution that is inconsistent with observations.

Assigning Blame for the Blackouts in Texas

Posted on February 18, 2021 by | 553 comments

By Planning Engineer

The story from some media sources is that frozen wind turbines are responsible for the power shortfalls in Texas. Other media sources emphasize that fossil fuel resources should shoulder the blame because they have large cold induced outages as well and also some natural gas plants could not obtain fuel.

Extreme cold should be expected to cause significant outages of both renewable and fossil fuel based resources. Why would anyone expect that sufficient amounts of natural gas would be available and deliverable to supply much needed generation? Considering the extreme cold, nothing particularly surprising is happening within any resource class in Texas. The technologies and their performance were well within the expected bounds of what could have been foreseen for such weather conditions. While some degradation should be expected, what is happening in Texas is a departure from what they should be experiencing. Who or what then is responsible for the shocking consequences produced by Texas’s run in with this recent bout of extreme cold?

The progress of the COVID-19 epidemic in Sweden: an update

Posted on February 18, 2021 by | 787 comments

By Nic Lewis

I thought it was time for an update of my original analysis of 28 June 2020. As I wrote then, the course of the COVID-19 pandemic in Sweden is of great interest, as it is one of very few advanced nations where no lockdown order that heavily restricted people’s movements and other basic freedoms was imposed.

COVID-19: why did a second wave occur even in regions hit hard by the first wave?

Posted on January 10, 2021 by | 797 comments

By Nic Lewis

 Introduction

Many people, myself included, thought that in the many regions where COVID-19 infections were consistently reducing during the summer, indicating that the applicable herd immunity threshold had apparently been crossed, it was unlikely that a major second wave would occur. This thinking has been proved wrong. In this article I give an explanation of why I think major second waves have happened. Continue reading →
