Mining the Brine: Can Desalination Waste Become a Lithium Source?
Desalination brine is roughly twice as concentrated in lithium as seawater, and new methods are trying to harvest it. A ceramic membrane has enriched lithium more than forty-thousand-fold in the lab. But today's pilots process a tiny fraction of the brine a single plant produces — and commercial scale is years away.
Cooling the Concrete: How Cities Are Fighting the Urban Heat Island
Cities run hotter than their surroundings because dark, dense, paved surfaces absorb and trap heat. Reflective materials and large-scale greenery can measurably cool them — but the honest, measured figures are around 2°C of air cooling, not the uniform numbers often quoted. A look at Los Angeles, Medellín, Singapore and more.
Flash Droughts: When Drought Arrives in Weeks, Not Months
A flash drought intensifies over just a few weeks, driven by heat and air so dry it pulls moisture from soil and plants. Across most of the world's land regions droughts are arriving faster. The 2012 US flash drought caused around $30 billion in losses and cut the corn yield by about a quarter.
Noctilucent Clouds: The Glowing Clouds at the Edge of Space
Noctilucent clouds form 76–85 km up, from ice crystals freezing onto meteor dust in air colder than −120°C, and glow because they are lit from below the horizon after dusk. The leading idea for why they are spreading to lower latitudes ties them to rising water vapour from methane — but the climate link is not yet settled.
The Heat Dome: How a Lid of High Pressure Locks In Deadly Heat
A heat dome is a persistent high-pressure ridge that traps heat over a region for days or weeks. In 2021 it pushed Lytton, Canada, to a record 49.6°C; attribution found that event virtually impossible without climate change. We explain the omega-block mechanism and the 2024 South Asian extremes.
Lightning Superbolts: The Sky's Rarest, Most Extreme Strikes
Superbolts are the most extreme lightning strokes on Earth — up to a thousand times brighter than an average stroke. They cluster over the northeast Atlantic, the Mediterranean and the Andes, and peak in winter over the open sea, the mirror image of ordinary lightning.
Holding Back the Sea: The Engineering Fight to Save Historic Cities
Global sea level is now rising about 4.5 mm a year and accelerating. Venice's MOSE barrier has been raised around 100 times since 2020; New York is building a 1.45-billion-dollar coastal defence. The front lines of keeping historic cities above water.
Fog Tourism: Chasing the World's Most Atmospheric Weather
Fog forms in a handful of distinct ways, and each favours specific places and seasons. San Francisco's summer fog, Taiwan's mountaintop sea of clouds and the life-giving coastal fogs of the Namib and Atacama are world-class examples.
The Manufactured Oasis: Inside the Microclimates of Desert Resorts
Luxury resorts in hot, arid regions create artificial microclimates that run on enormous inputs of energy and desalinated water. In the Gulf, cooling can account for around 70% of summer peak power, and almost all drinking water is wrung from the sea.
Why Your Flight Is Getting Bumpier: The Jet Stream and Clear-Air Turbulence
Severe clear-air turbulence over the North Atlantic rose by around 55% between 1979 and 2020, driven by increasing wind shear in a warming atmosphere — and projections suggest it could double or triple by mid-century.
Last-Chance Tourism: The Race to See Coral Reefs Before They Bleach
The fourth global coral bleaching event, declared in 2024 and the most extensive on record, has exposed over 80% of the world's reef area to bleaching-level heat. The painful paradox of travelling to witness ecosystems our travel is helping to change.
The Best Northern Lights in Twenty Years: A Solar-Maximum Aurora Guide
The solar cycle peaked in October 2024, and strong auroras typically continue for two to three years afterwards — making the coming winters unusually rewarding. A practical guide to where, when and how to catch them.
Chasing the Rains: The Rise of Monsoon Tourism in Asia
A niche of travellers now chases the monsoon across South and Southeast Asia for the low prices, thin crowds and lush scenery. Our climate records show Mumbai receiving over 800 mm of rain in July alone — against barely a millimetre in January.
Snow on Demand: How Artificial Snow Is Saving — and Straining — the Alps
Artificial snow now covers roughly 90% of Italy's pistes and three-quarters of Austria's. It keeps low and mid-altitude resorts open, but at a steep cost in water and electricity — and it cannot save the lowest resorts, which are already closing.
October Is the New July: How Mediterranean Heat Is Rewriting the Travel Calendar
Record heatwaves are pushing tourism out of July and August into the cooler shoulder seasons. Greece welcomed 40.7 million visitors in 2024 — its hottest summer on record, the same summer the Acropolis closed during peak afternoon heat.
Microplastics in the Clouds: A New Atmospheric Frontier
From Mt Fuji to Mt Tai to the French Pyrenees, microplastics have been found in cloud water at concentrations of up to 463 particles per litre. Laboratory work confirms they nucleate both droplets and ice crystals. The signature is small, consistent, and growing with atmospheric ageing.
Sponge Cities at the Edge: Shanghai, Zhengzhou and the 1-in-30 Year Ceiling
China launched the Sponge City Initiative in 2015 with a 2030 target of 80% of urban land absorbing 70% of rainfall. The 2021 Zhengzhou flood showed the design ceiling. Shanghai's Lingang passed its 2024 typhoon test — but no city has built drainage for what climate change is now producing.
The Desalination Boom and the Brine It Leaves Behind
Global desalination has grown 40% since 2020. For every cubic metre of fresh water, 1.5 cubic metres of hyper-saline brine returns to the sea — destroying seagrass meadows and creating localised dead zones. Can circular-economy lithium extraction close the loop?
