Chile has been suffering devastating wildfires this month. So far, nearly one million acres have burned, 26 people have died, thousands have been injured, and many left homeless. Central Chile has been plagued by a 13-year megadrought, and its interior minister suggested the fires should serve as a wake-up call about the climate emergency. The recent heat has also been felt in Uruguay, Paraguay, and Argentina, where temperatures reached 122 F in Buenos Aires.

The commercial interest in deep-sea mining for minerals is growing rapidly because of demand for metals, such as copper, cobalt, zinc, and gold, among others, to be used in batteries and electronic devices. Some companies have plans to use large robots to scrape the ocean floor, similar to strip mining on land, that could affect not only the seabed but also much of the marine environment with plumes of sediment and harmful noise.

As global temperatures rise, glaciers around the planet are melting and creating lakes where there was once ice. The massive pools are usually kept in place by dams of ice and rock, but prolonged high temperatures or an abrupt heat wave could cause them to rupture, sending rock, ice, and water cascading downhill.
Global distribution of glacial basins, color-coded according to mountain range, with ‘High Arctic and Outlying Countries’ (HAOC) representing all basins outside of the four main ranges in this study (Alps, Andes, High Mountains Asia (HMA) and Pacific North West (PNW)). Pie charts show the proportion of exposed population as individual country contributions to the mountain range total, with pie charts sized according to percentage contribution to the 2020 global total.
Fans who attended this year’s Super Bowl in Glendale, Arizona, will have chowed down a lot of chicken wings, burgers, and french fries. And while that greasy food may not do much for waistlines, the oil it’s cooked in won’t go to waste. It could be fuel for future airline flights.
