The extent of humanity’s influence on the planet has become increasingly clear in recent years. From the alarming accumulation of plastic waste in our oceans to the sprawling growth of urban areas, the size of our impact is undeniable.

The concept of the “ technosphere” aims to reveal the immense scale of our collective impact. The concept was first introduced by US geologist Peter Haff in 2013, but paleobiologist Jan Zalasiewicz has since popularised the term through his work. The technosphere encompasses the vast global output of materials generated by human activities, as well as the associated energy consumption.

Indigenous group opposing destructive mining in Maipo river sends greetings to anti-capitalist sabotage campaign

The group “Insurrectional Cell for the Maipo: New Subversion” (Célula insurreccional por el Mapio. Nueva Subversión) has claimed last Saturday’s arson attack in the region of Valparaíso, Chile. Seven trucks were set ablaze at the El Melón concrete plant during the night of arson, and the company offices were also targeted. No injuries were reported.

Dozens of once-pristine rivers and streams in Alaska’s Brooks Range are turning an alarming shade of orange. The discoloration, according to a new study published in the journal Communications Earth and Environment, is likely caused by the thawing of permafrost, which is exposing previously frozen minerals that are now leaching into the waterways.

The research team, led by ecologist Jon O’Donnell from the U.S. National Park Service, documented 75 locations across a vast area of northern Alaska where the crystal-clear waters now appear heavily stained. Using satellite imagery and field observations, the scientists determined that the onset of this discoloration coincided with a period of warming and increased snowfall in the region over the past decade.

Editor’s notes: Methane(CH4) is the main component of natural gas. The word comes from the Greek methy “wine” + hylē “wood.” However, marketers came up with the term natural gas rather than methane gas to give it a clean, green image. Methane is produced by decaying organic material. Natural sources, such as wetlands, account for roughly 40% of today’s global methane emissions. But the majority comes from human activities, such as farms, landfills, dams and wastewater treatment plants – and fuel production. Oil, gas, and coal together make up about a third of global methane emissions. It can leak anywhere along the supply chain, from the wellhead and processing plant, through pipelines and distribution lines, all the way to the burner of your home’s stove or furnace. Once it reaches the atmosphere, methane’s super heat-trapping properties render it a major agent of warming. Over the last 20 years, methane has caused 85 times more warming than the same amount of carbon dioxide. But methane doesn’t stay in the atmosphere for long. Unlike carbon dioxide, which lingers in the atmosphere for a century or more, methane only sticks around for about a dozen years.
