For a long time, experts have been studying megaplumes and their impact on the environment. However, due to the fact that eruptions occur very deep, they are difficult to detect and analyze.

British scientists studied the North Escanaba lava flow in the northeast Pacific Ocean. Plumes of hot water are capable of carrying particles of volcanic rock at a distance of 5 kilometers from the eruption site. And one eruption of North Escanaba created a megaplume with enough power to supply the United States with energy for several days.

Thus, according to the researchers, the vascular system present in trees must maintain hydraulic resistance to ensure efficient movement of water and nutrition through the tree, and for this characteristic, at a certain point Da Vinci’s rule ceases to apply.

It is noted that in order for fluids to move successfully from the bottom to the top, the vascular channels in trees must have a certain size in order for resistance to be maintained, so closer to the end of the plant, its volume must become smaller, causing the capillary ratio to be much higher.

According to a recent study, 84 percent of airborne plastic microparticles are picked up from interstates and highways. This is due to tires naturally wearing out. Another 11 percent are lifted from the ocean surface.

Plastic microparticles also arise due to the breakdown of bags and bottles, during washing, when the fibers of things peel off.

Old records, including the works of Aristotle, mention “cold fire” glows coming from fungi that live on rotting wood. It was originally thought that their glow served to attract pollinators.

The researchers studied the fungus Neonothopanus gardneri and found that it regulates its bioluminescence according to a circadian rhythm, peaking at night to attract more insects that could detect it in the dark.

The mechanism of spread through animal attraction gives fungi a great advantage, especially in dense forests where it is more difficult for spores to settle over a large area.

At the UN climate change conference in Dubai, he pointed out the drawbacks of mass tree planting, such as suppression of biodiversity and insufficient carbon capture.

Crowther also warned that tree planting could be used as an excuse to avoid cutting emissions. He called for a focus on preserving existing forests, allowing them to grow and develop naturally, as he believes this will help offset emissions more effectively. Crowther’s work now focuses on stopping “greenwashing” and making real positive environmental gains.
