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 only 0.9 meters in ‘modern scale configuration’, but over 2 meters [2.9-4] in unspecified other configurations).

The public policy debate about climate science shows the dysfunctional nature of the US media. Here’s another example of how propaganda has contaminated the news reporting of this vital subject, looking at stories about a new study of our oceans.

When it comes to climate change, the procedure by which experts assess the accuracy of models projecting potentially ruinous outcomes for the planet and society is surprisingly informal. – Michael Oppenheimer

We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning). Factorial simulations with multiple global ecosystem models suggest that CO2 fertilization effects explain 70% of the observed greening trend. – Zhu et al.

In our view, the fact that so many scientists agree so closely about the [causes of the] earth’s warming is, itself, evidence of a lack of evidence for [human caused] global warming. – D. Ryan Brumberg and Matthew Brumberg

China has big plans for low-carbon electricity, primarily to reduce air pollution but also with the intent of reducing CO2 emissions and building a true 21st century power grid. Is it going to succeed?

The Paris Agreement and, more generally, climate change policy, almost perfectly illustrate the contradictions of the post-modern industrialized world risk society, characterized by perceived threats confirmed by politicized science and governed by sub-politics beyond democratic control. – Lucas Bergkamp

A revolution could be achieved with nuclear power if we remove the factors that caused the large cost increases during and since the 1970’s, i.e. return to the learning rates demonstrated before 1970.

Inappropriate use of linear regression can produce spurious and significantly low estimations of the true slope of a linear relationship if both variables have significant measurement error or other perturbing factors. This is precisely the case when attempting to regress modelled or observed radiative flux against surface temperatures in order to estimate sensitivity of the climate system. Continue reading
