I just added a new graphical timeline of our rapidly changing planet (through 2025)... This high-resolution visualization is now permanently featured at the very bottom of my climate change indicators webpage. ➡️ Check it out here: zacklabe.com/climate-change…

What does the latest research tell us about Earth's changing climate? The '10 New Insights in Climate Science 2025' report highlights ten key findings, including accelerating ocean warming, record‑breaking global heat and reduced carbon uptake on land.

1.4 billion people are living on poisoned soil. A new global map reveals where:

This is unbelievably bad. The warmth of the waters in the Caribbean Sea extends so deep that Melissa could remain stationary for days and still not upwell cooler water — 30°C over a layer extending down to 50 meters or more. This thing will basically have endless ocean fuel.

In Antarctica, ice shelves extend from glaciers and float on the ocean like tethered rafts. Warming seas lap at the ice, melting it from below. When these shelves will collapse is a question for basic physics. quantamagazine.org/how-soon-will-…

Mapping ocean currents sounds simple. But it's one of the hardest problems in climate science. NASA spent decades developing ECCO to solve it. Here's the breakdown:

"Probability does not exist." This provocative quote is by the Italian statistician and probabilist Bruno de Finetti. It encapsulates the core idea of Subjectivism or Bayesianism, a major school of thought in probability. De Finetti argued that probability is not an objective property of the world (like mass or temperature). Instead, it's a measure of an individual's degree of belief about an uncertain event, based on their knowledge and evidence. Essentially, he meant that a "50% chance of rain" doesn't exist in the clouds themselves; it exists in the mind of the meteorologist who assigns that value based on the data they have. It's a powerful statement that reframes probability as a tool for reasoning under uncertainty, rather than a feature of physical reality.

Climate change contains feedback loops. A warmer atmosphere, for example, can hold more water, which in turn doubles the total warming and draws even more water into the air. quantamagazine.org/the-climate-ch…

A pretty spectacular satellite image of the ex-hurricane #Gabrielle now approaching the Iberian Peninsula. The center of the low, around 992 mbar, will go onshore in central Portugal tonight. Severe winds and high waves are expected along the coast.

Brace for Hurricane #Gabrielle impact on the Azores, which is expected to have significant winds and storm surges by Friday morning. severe-weather.eu/global-weather…

Each year, enough dust to build 1,000 copies of the Great Pyramid of Giza is lofted into the atmosphere. These grains of sand seed cloud formation, fertilize the seafloor, and impact heat retention. Mere specks of dust influence the nature of the entire planet. quantamagazine.org/how-climate-sc…

Sea-surface temps are running a fever across most of northern oceans. Not a good look going into fall. Above-normal SSTs mean 1) more evaporation => heavier precipitation, 2) warmer air, 3) slow sea-ice growth, and 4) unusual weather patterns. Buckle up!

For decades, nobody knew why coho salmon in Seattle’s streams would swim upstream strong and healthy, then spiral, twitch and suffocate within hours of rain. Whole runs gone overnight. In 2020, researchers solved the mystery, a tyre additive called 6PPD. It reacts with ozone in the air (yes, the same ozone layer you’ve heard about) and transforms into 6PPD-quinone, a chemical nobody had studied until recently. For salmon, it’s instant poison. Exposure kills them in less than three hours. Now the story has widened. New research confirmed this isn’t just a salmon problem. Tyre-wear dust ripples outward, disrupting trout, aquatic insects and even the microbial base of rivers. It doesn’t stop at water. It’s airborne. In Seoul, researchers measured 61,000 kilograms of tyre dust drifting into the air every year. Each particle is small enough to ride deep into human lungs and never leave. This is the hidden chemical footprint of modern life. One tyre revolution at a time, we are grinding rivers, ecosystems, and ourselves into dust. weareoceanrising.substack.com/p/the-tyre-poi…

Turkey registers it's hottest day on record. Turkey's meteorological service has confirmed the 50.5C recorded in Silopi on Friday was an all-time temperature record for the country. It was also Turkeys first 50C day. 132 weather stations in total broke July temperature records.

Here is an old favourite. Shipping lanes. This time drawn using the Spilhaus projection, which centers the map on Antartica and presents the worlds oceans as one continuous body. Created by Athelstan F. Spilhaus, a South African-American geophysicist and oceanographer in 1942

You are looking at Sea Surface Temps last June (2024) compared to this June (2025). Much of the World, especially the tropics which are the biggest area of ocean basin, have finally cooled off (blue) after a couple of blazing hot - historic - years. Some of this is due to the ending of the 2023-24 strong El Nino. This has a big impact on weather patterns globally with less heat (relative only to 2024) available. Two exceptions are the Mediterranean and the Mid-latitide Pacific.
