Shout out to my colleagues on the SeibalSim Project, Gerardo Aldana (UCSB), Toni Gonzalez (UCSB), and especially Tommy Thelen (NCEAS) for getting this thing ready for primetime. The new R package, villager, is a great new tool to carry out agent-based modeling work. It is designed for archaeologists and non-expert modelers to test their ideasContinue reading “villager is up on CRAN”
Reposted from a comment I made to Linkedin post on reflections from COP26. China has advertised its progress transitioning away from coal, particularly in its energy sector. Part of this is due to domestic political reasons: a decade ago, the Chinese government in Beijing faced enormous demonstrations from ordinary Chinese opposed to the cost inContinue reading “Just my reflections on COP26”
With new dating on charcoal from a context stratigraphically above human footprints set in the playa at Alkali Flat in the US, Bennett et al. writing in Science demonstrate the presence of humans in North America between 23-21 ka ago. This is a big deal. There has been a lot to suggest that humans occupiedContinue reading “Pushing back the origins of New World human occupation”
David Vetter writes in Forbes that CROs have great potential in carbon markets, after interviewing lead-author Johannes Bednar and co-authors Myles Allen and Michael Obersteiner. Also contains an audio rendition. Writing in Cosmos, Ellen Phiddian connects the possible application of CROs to a report from a Swiss reinsurance institute that explains the enormous potential costContinue reading “Press from CROs Nature paper”

Bednar, J., Obersteiner, M., Baklanov, A., Thomson, M., Wagner, F., Geden, O., Allen, M., Hall, J. (2021). Operationalizing the net negativeContinue reading “Operationalizing the net negative carbon economy”
The UEFA Euro 2020 tournament is being played out during a heat wave in Europe, including some of the warmest temperatures in recorded history (which is pretty long there). A friend of mine in Vienna was texting his complaints about it to me today. Well, California says, “hold my kombucha”: Update: The hottest temperatures everContinue reading “Hot topic”
This is a nice discussion of climate impacts on migration on a US cable news network.
One of my former colleagues at IIASA, Lena Höglund-Isaksson, speaks to The World (a syndicated radio program from Public Radio International & National Public Radio in the USA) about her work on the new UN report on methane emissions.
Cheeky stuff when utilities attack new suppliers’ free market access, although it shouldn’t be surprising. I have been interested for some time in how big energy companies (from utilities to the fossil fuel industry suppliers) will attempt to liquidate assets that don’t really have another use. If what we now face really is a rapidlyContinue reading “Thinking about stranded energy assets today”
The new administration has a mandate for responsible government, decency, and truth-telling. This can be encapsulated in its policies to deal with climate change. It enters office with, apparently, the largest collection of climate experts in history. This is good, because it is going to be tough to solve the climate change problem, which isContinue reading “President Biden sets the correct tone on climate change from the word “go””
