We can move beyond the capitalist model and save the climate – here are the first three steps | Jason Hickel and Yanis Varoufakis Capitalism cares about our species’ prospects as much as a wolf cares about a lamb’s. But democratise our economy and a better world is within our grasp, say Jason Hickel and Yanis Varoufakis

"After all, we are the producers of the goods, the services, the technologies. It is our labour and our planet’s resources that are at stake. And so we must claim the right to decide what is produced, how, and for what purpose."

I actually worked on some Callitris years ago for Val LaMarche’s S hemisphere project. I’ll look that old one up, I need more from the south for Oldlist!

Hi Pauline, excellent question, and no we did not consider those at all. I’ve not included any in my Oldlist, mainly due to questions of dating continuity of genets between living and remnants. But a ripe area of study for sure!

Thanks Steve! I do need to modernize the list someday soon…

At the root of all our problems stands one travesty: politicians’ surrender to the super-rich | George Monbiot There are many excuses for failing to tax the ultra-wealthy. The truth is that governments don’t tackle the problem because they don’t want to, says Guardian columnist George Monbiot

Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density Diameter growth is an important and good indicator of forest carbon production. However, size-related changes in wood density, which are usually neglected, are critical for accurate short- and long-t...

#Tree stems accumulate biomass by adding volume of certain density. Which factor is more important?

Using tropical #treering data we found: diameter increment explains biomass growth at short term; wood density at long term.🌎🌐🍁

Intensifying Fire Season Aridity Portends Ongoing Expansion of Severe Wildfire in Western US Forests Area burned by wildfire has increased in western US forests over recent decades.

Good article, but wildfire is never “preventable”; all of the management strategies outlined will never stop wildfire from burning at some point, but will “mitigate” severe effects and damage to human infrastructure. But fire itself is inevitable in these ecosystems; best accept that fact.

I can die happy: saw a herd of elephants on the Okavango. Photos still to be processed. Meantime here’s a shot of elephants coming to drink at the Elephant Sands in Botswana. Elephants everywhere around here!

low severity surface fire burning through a ponderosa pine forest

low severity surface fire burning through a ponderosa pine forest

The Turkeyfeather Fire in the Gila Wilderness, NM has burned as a low-severity fire over about 24,000 acres (so far). This is a continuation of a fire regime that existed for millennia before the 20th century. This 🧵reviews the fire history of the Gila, as my colleagues and I have studied it. 1/18

Hi Isabella, nice write up and interesting work! FYI Ros was the San Juan fire ecologist before her back country career and has published several papers on fire and forest histories. EG Brown and Wu 2005 Ecology, my favorite study!

Just arrived back in US on flight from London that was maybe half full. Mostly American accents I heard. Bad time to be in the US tourist business…

The view from the top of the Eiffel Tower yesterday. I was here 51 years ago wandering Europe for the summer but too cheap to pay to go to the top; finally made it!

It was uplifting to see ongoing studies of rare & threatened species, old-growth forests, bird energetics, the creativity of ecological education, & other acts of resilience at the the Northeast Natural History Conference as others said Hands Off (<- thank you)

EyeSocketCutting-1

#firescarfriday Here's Chris Baisan from Tree-Ring Lab in Tucson sampling a giant sequoia stump with several "eye socket" fire-scar catfaces. Record was 80+ fire scars in one of these; ground level in the past was higher, hence the whole socket begin visible.
