#Fire is unique to #Earth. As far as we know no other planet has fire. Here is a nice summary of the geological history of fire including its relation to the evolution of #pines and #grasses

Lesson from
Left: The contribution of tree to area is increasing
Right: plantations act as a net carbon source in contrast to the forests ()

Good : It suggests that the most frequent (the mode) in the Northern Hemisphere is currently close to the maximum temperature for the 1951-1980 period.

This reminds me of the (the model developed by to demonstrate the hypothesis), where black daisies (, etc) reduce & warm the planet. But we lack white daisies for the negative ! We are in the positive phase! (eg Box 1 in https://sciencedirect.com/science/article/pii/S0169534722000611)

FROM @nickcowern: Earth has darkened significantly over the last 20y; satellite data show a roughly 2% reduction in reflected sunlight

In Eurasian , are typically surface fires. This contrast with the American boreal forest where crown fires are dominant.

Nice to see old ( sylvestris) in Urbión mountains, ,

In Spain, we have too many young trees and too few old trees!

Old allows to see changes. Here the old bridge of the Douro river (, Spain) before the 1902 and now (2023).

Nice paper in Science, but the idea of fire a primary cause of megafauna extinction only appears in the cover & in the abstract ("Time-series modeling implicates large-scale fires as the primary cause of the extirpations ...") but not in the article!

The top journal #Science recently rejected reply letters from at least 3 groups of top scientists to a poor paper they published. Science only accepted comments as footnotes to the original article. This is surprising, as scientific debate is an important part of the scientific process. It is disappointing that a top journal like Science would not be more open to scientific debate.

We are in the 21st C & the journal #Science publishes a #vegetation #model that fails to consider key mechanisms of the system modeled. And the authors use the model to criticize the dynamics of the systems!

Unfortunately #Science don't accept reply letters only comments as footnotes

We need mechanistic models to explain Alternative Ecosystem States in tropical vegetation

I'm looking for the by Charles S Elton entitled "Animal Ecology and Evolution" (Clarendon Press, @oxunipress, 1930).

Do you know where I can find a digital version? Do you have a paper copy? Any suggestion would be appreciated! - boosts & RT are also appreciated!
