Climate Adam - Can Solar Halt the Desert?
29 October 2025 @ 3:33 pm
This video includes personal musings and conclusions of the creator climate scientist Dr. Adam Levy. It is presented to our readers as an informed perspective. Please see video description for references (if any).
Video description
Solar power has become ridiculously cheap. And unbelievably powerful at tackling climate change. Today I discuss two of the most absolutely overpowered places we can build solar photovoltaics: reservoirs (floatovoltaics) and deserts. But the future of solar is so bright, that it's worth building even in less-than-ideal locations. Let's take a look at the sunny story of today's solar PV, and what that means for our climate!

Fact brief - Is there empirical evidence for human-caused global warming?
28 October 2025 @ 3:37 pm
There are multiple lines of evidence that our greenhouse gas emissions are warming the planet.
The greenhouse effect is the process whereby “greenhouse” gases such as carbon dioxide create a kind of atmospheric blanket, absorbing outgoing heat energy and re-radiating a portion of iA “controversial” methane metric?

This is a re-post from And Then There's Physics
There’s a recent Carbon Brief article about a supposedly controversial methane metric. The metric in question is GWP*, which I’ve actually written about before. Methane emissions are typically compared to CO2 using a metric known as Global Warming Potential (GWP). These are often measured over periods of 20 years (GWP20) or 100 years (GWP100). For methane GWP20 has a value of about 80, while GWP100 has a value of about 30.

22 October 2025 @ 9:02 am
Climate Obstruction: A Global Assessment is a new book from Brown University’s global Climate Social Science Network, for which a team of more than 100 scholars explored who’s blocking action on climate change and how they’re doing it. John Cook - founder of Skeptical Science and senior research fellow with the Melbourne Centre for Behaviour Change at the University of Melbourne - co-authored chapter 7 in the book titled "Understanding the Political and Psychological Roots of Climate Misinformation and Its Impact on Public Opinion". The book is available open access for download from the Climate Social Science Network.

50 fact briefs published in collaboration with Gigafact!
21 October 2025 @ 3:27 pm
In April 2024 we announced the (renewed) collaboration between Gigafact and Skeptical Science to create fact briefs, short but credibly sourced summaries that offer “yes/no” answers in response to claims found online. Initially, we published new fact briefs on Saturdays, but switched to Tuesdays earlier this year and while we try to have a new fact brief out each week, we sometimes miss a week due to time constraints and vacations. Regardless of that, we published fact brief #50 - Are humans responsible for climate change? - on September 30, 2025 and thought that this little milestone might make for a good reason to write a short blog post about the current status of this project.
India’s power-sector CO2 falls for only second time in half a century
20 October 2025 @ 6:53 pm
This is a re-post from Carbon Brief
India’s carbon dioxide (CO2) emissions from its power sector fell by 1% year-on-year in the first half of 2025 and by 0.2% over the past 12 months, only the second drop in almost half a century.
As a result, India’s CO2 emissions from fossil fuels and cement grew at their slowest rate in the first half of the year since 2001 – excluding Covid – according to new analysis for Carbon Brief.
The analysis is the first of a regular new series covering India’s CO2 emissions, based on monthly data for fuel use, industrial production and power output, compiled from numerous official sources.
(See the regular series on China’s CO2 emissions, which

Mountain glaciers recouple to atmospheric warming over the twenty-first century, Shaw et al., Nature Climate Chang
Recent studies have argued that air temperatures over many mountain glaciers are decoupled from their surroundings, leading to a local cooling which could slow down melting. Here we use a compilation of on-glacier meteorological observations to assess the extent to which this relationship changes under warming. Statistical modelling of the potential temperature decoupling of the world’s mountain glaciers indicates that currently glacier boundary layers warm ~0.83 °C on average for every degree of ambien
