Good question. It really looks as if all that red smoke over the Atlantic might be the smoky remnants of the huge forest fires that we have had in Europe, not least in Sweden, during this blisteringly hot summer.

Or maybe it all originated in California? Haven't you had forest fires there, too?

Viewing the wind patterns that carry these aerosols shows the eastern US being impacted by the western fires. When the Yellowstone super volcano goes, it will blast a big hole in the Rockies and cover the eastern half of the US in a major aerosol cloud.

Goodby sunny days for a long time!

Wondering what's the cause of all the "black carbon particles in red from combustion processes" in central Africa?

Cooking food over open fire, making a lot of smoke?

<<Slash-and-burn agriculture, or fire–fallow cultivation, is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. (Preparing fields by deforestation is called assarting.) In subsistence agriculture, slash-and-burn typically uses little technology. It is often applied in shifting cultivation agriculture (such as in the Amazon rainforest) and in transhumance livestock herding.

Sometimes there are several cycles of slash-and-burn within a few years' time span. For example, in eastern Madagascar, the following scenario occurs commonly. The first wave might be cutting of all trees for wood use. A few years later, saplings are harvested to make charcoal, and within the next year the plot is burned to create a quick flush of nutrients for grass to feed the family zebu cattle. If adjacent plots are treated in a similar fashion, large-scale erosion will usually ensue, since there are no roots or temporary water storage in nearby canopies to arrest the surface runoff. Thus, any small remaining amounts of nutrients are washed away. The area is an example of desertification, and no further growth of any type may arise for generations.>>

<<According to the UN Food and Agriculture Organization (FAO), indigenous (also known as “old-growth”) forests in Africa are being cut down at a rate of more than 4 mn hectares per year — twice the world’s deforestation average. According to the FAO, losses totalled more than 10 per cent of the continent’s total forest cover between 1980 and 1995 alone. Saving Africa’s forests from the chainsaw and axe of encroaching humanity is essential to the health and productivity of much of the continent’s economy, experts point out. They cite the forests’ roles as watersheds, defences against soil erosion and regulators of local weather conditions.>>
