When you go for a walk with a geologist, you see some things you wouldn't otherwise see ... Here is a fossil coastal dune with lots of holes from ancient roots!!

He died on December 4th (the funeral will be on the 12th)

Rocky area showing alternate hard (limestone) and soft (marls) layers, indicative of warmer and colder periods, respectively (geological scale)

Evidence of climate change cycles (Milankovitch cycles) preserved in the rock record!
Hard limestones: warmer periods
Soft marls: colder periods

To remember William Bond, you could listen to his powerful talk on behalf of grasses! It is a seminal lesson in savanna ecology. Personally, I also find it nice to hear his voice.

Three books by W. Bond and collaborators: Fire and plants (1996), Fire in Mediterranean ecosystems (2012), and Open ecosystems (2019).

I'm very sad to say William Bond, of the University of Cape Town & Fellow of the Royal Society (@royalsociety.org ), has passed away. It is a great loss. He was an enthusiastic ecologist and a critical thinker. I learned a lot, and I still had a lot to learn from him. RIP. 😢

I guess they mean 800 million hectares, which is probably a bit closer to the size of Australia ...

Two plots with the global mean annual burned area (left) and fuel consumption (right), for the 2002–2022 period, in grasslands & non-grasslands.

The new Global Fire Emissions Database (GFED5, 2002–2022) shows that at the global scale 1) by far, most area burned are grasslands; 2) area burned is declining; & 3) fuel consumption is increasing: ie, fires are increasing in forests & encroached grasslands.

"... on average, 800 hectares of land – an area roughly the size of Australia – has burned annually over the past two decades." @carbonbrief.org !!😵‍💫

The storks in the photo are not escaping the fire (see ALT); but happily waiting to feed on small creatures exposed or killed by it.

CITES CoP20 Decision Allows International Trade in Saiga Horn, Strongly Opposed by WCS Samarkand, Uzbekistan, Nov. 28, 2025 – Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) today voted to allow international commercial trade in sai...

Today at #CITESCoP20, governments voted to allow commercial international trade in saiga horn under newly established quotas from Kazakhstan.

We strongly opposed this outcome.

Y así debería de ser SIEMPRE. No olvidéis que el genocidio sigue, a pesar del alto el fuego, y que la gente sigue siendo masacrada a diario y muriéndose de hambre. Hay que posicionarse y ya no vale ponerse de lado ante tal atrocidad. Dicho esto, PUXA PALESTINA LLIBRE.

El otro día estaba en una reunión virtual (científica), y había uno de ellos hablando como si nada, qué incomodidad!

Hoy, 29 de noviembre, el Día Internacional de la Solidaridad con el Pueblo Palestino y 78 aniversario de la expulsión de 750.000 palestinos de sus tierras, tenemos una cita con el derecho a la existencia y los derechos humanos del pueblo palestino.

Despite the general perception, global emissions from biomass burning have shown a decreasing trend over the last 23 years, a pattern that is reversed in North America.

Cuánto trabajo cuesta crear algo valioso, cuánto esfuerzo y sacrificio (me consta) de tanta gente para que ahora venga esta pandilla ignorante, rancia y ratera a destruirlo en un momento. Desesperante.

Pictured is post-disturbance logging that entailed removal of biological legacies and increased fine fuels on the Stanislaus National Forest in California, two years after the 2013 Rim fire, one of the state’s largest fires at the time. Image credit: Doug Bevington (photographer).
