In August 2026, the #SeaIce global extent was 7.2% below 1991-2020 mean. Since the beginning of records (1978):
- #Arctic, 12th lowest monthly mean, with 9.1% less extent than normal (-617,526km²)
- #Antarctic, 4th lowest monthly mean, with 6.5% less exent than normal (1,178,424km²)

💁🏻‍♀️ TIL: 🧵🌐 The hairy ball #theorem says you can’t comb a #sphere smooth without a cowlick somewhere.

The same rule explains why #Earth always has a #cyclone spinning, why #fusion reactors use #doughnut shapes, and why omnidirectional antennas can’t exist. #Wind patterns over the #Arctic and #Antarctic circles illustrate the proof.

Who needs #BioLabs when there's all sorts of #bacteria about to be exposed after thousands of years!

Researchers issue warning after making grim #Antarctic discovery: 'We are only beginning to understand'

Story by Daysia Tolentino, January 29, 2026

Excerpt: "A study published in the journal #Biocontaminant examined the effects of #GlacialMelting on our #WaterSupply.

"#Glaciers serve as reservoirs for #AntibioticResistanceGenes, or #ARGs, and other #microbes. When they are released from the ice, they enter our water systems, posing a major health risk to people downstream.

"Millions of people get their water from glacier-fed rivers and lakes. ARGs are strands of DNA that make bacteria more resistant to drugs. When ARGs in #meltwater make their way into our water supply, they become a global public health risk.

"The study emphasizes the importance of viewing glaciers, rivers, and lakes as being part of a 'glacier continuum.' This means they are an interconnected system rather than separate environments.

Why are melting glaciers concerning?

"From our gas-powered cars to #overconsumption, human activity has contributed to the production of heat-trapping gases that warm the planet. Rising global temperatures have caused glaciers to rapidly melt, causing elevated sea levels and releasing ARGs.

"ARGs from melting glaciers are worrisome because they help facilitate the spread of diseases. This threat is compounded by the fact that our growing #microplastic problem is also helping #AntibioticResistant #bacteria breed. As a result, #medicines are being rendered less effective."

In the interests of my resolution to not spread bad news, here's something positive - looks like the #Antarctic #OzoneHole is getting smaller.
My ace colleagues @dmidk have a webpage they update regularly on this stuff: http://psc.dmi.dk/antarctica/

The annual #ozonehole over the #Antarctic is developing again. If you want to keep track, visit our website for all the latest charts and details: https://atmosphere.copernicus.eu/monitoring-ozone-layer

There you will also find the daily updated 3D rendering of the ozone hole evolution in 2024.
