Despite popular support for a 25% levy on gas exports, Anthony Albanese opposes it and there is little discussion about how to reduce our usage
We’re yet to see next month’s Australian federal budget, so mark this column with an asterisk. But barring a late change it is likely it will do a remarkable thing: give fossil fuel industries what they want.
That’s worth noting this week, as representatives from 57 national governments including Australia meet in Colombia for the first international conference on transitioning away from fossil fuels. That gathering heard France aims to remove coal from its national grid by 2027, end oil dependency by 2045 and stop using fossil gas by 2050.

More datacentres and warmer conditions helped push electricity demand to record highs in the first three months of the year, according to Australia’s Energy Market Operator, while growth in batteries kept average wholesale prices down.
Electricity demand – from households, business and industry – reached record levels of 25GW in Q1 2026, an increase of 1.2% compared with the same quarter last year. Across the grid, this growth was offset by record output from rooftop solar.

The ZSL has given us the word ‘zoo’, inspired artists and birthed a quarter of all Sumatran tigers. It has fascinated me since childhood – and the world since 1826
In the spring of 1826, two extraordinary things occurred in central London. The first was the death of Chunee the elephant. On 1 March at Cross’s Menagerie, upstairs in the Exeter ’Change on the Strand, Chunee was killed by a firing squad in the cramped enclosure where he’d been kept for the previous six years.
By this point Chunee was more than three metres (10ft) tall and weighed at least five tonnes. Like all adult male elephants, he periodically went into musth, when his body was flooded with testosterone, making him aggressive and uncontrollable. After Chunee injured one keeper (apparently deliberately) and accidentally killed another, the proprietor, Edward Cross, decided to have him destroyed.

Pace of sea-level rise has turned Outer Banks coastal area into a ‘canary in the coalmine’ for other east coast communities
Moving house has a more literal meaning on Hatteras Island, the slender hook of land that juts off the coast of North Carolina. After a slew of houses toppled spectacularly into the Atlantic Ocean recently, entire buildings are now being lifted on to wheels to flee the rapidly eroding coastline.
Since September, 19 homes have been lost to waves that tore them from their pilings, sending them crashing into other structures like bumper cars before breaking up in the ocean. Spooked homeowners have turned to the unusual services of Barry Crum, a lifelong Hatteras resident who has become the island’s main house mover.

Rush for lithium, cobalt and nickel is ravaging livelihoods, water and health of world’s most vulnerable, UN study says
Critical minerals such as lithium, cobalt and nickel are becoming the “oil of the 21st century” as the scramble for precious metals deepens poverty and creates public health crises in some of the world’s most vulnerable communities, a report by the UN’s water thinktank has found.
The investigation by the United Nations University Institute for Water, Environment and Health (UNU-INWEH) concluded that the growing demand for lithium, cobalt and nickel used in batteries and microchips is draining water supplies, eroding agriculture and exposing communities to toxic heavy metals.

Colombia president Gustavo Petro tells 57-country talks on a green energy transition that fossil fuel interests could destroy humanity
The world is threatened by a “suicidal” model of capitalism that is leading to war, fascism and the potential extinction of humanity, Colombia’s president has said, as he convened 57 governments to address the climate crisis.
Gustavo Petro blamed fossil fuel interests for taking ever more desperate measures to prevent a transition to green energy. “There is inertia in the power and the economy of this archaic form of energy – fossil fuels – that lead to death. Undoubtedly, that form of capital can commit suicide, taking with it humanity and [other] life,” he said. “The question that needs to be asked is whether capitalism can truly adapt to a non-fossil energy model.”

The bizarre vertical flight pattern has long puzzled experts but new research reveals why it may play a crucial role in the insect’s survival
On a spring evening along the banks of the River Thames, thousands of mayflies can be seen engaging in what may be one of the world’s oldest dances. In the fading light, the males make a steep vertical climb, flip over and float back to Earth – wings and tail outstretched in a skydiving posture so as to drop slowly through the sky.
Mayflies are among the world’s oldest winged insects, emerging roughly 300m years ago – long before dinosaurs walked the Earth. Even the Mesopotamian poem the Epic of Gilgamesh, one of the oldest pieces of literature, makes reference to the short-lived mayfly. Over the epochs, the insect’s basic design has changed very little compared with the fossils of their ancestors.

A KCL study has found that exposure during the first trimester of pregnancy delayed speech development
Babies exposed to higher levels of air pollution in the early stages of pregnancy take longer to learn to speak than those exposed to lower levels in the womb, new research suggests.
A study by researchers from King’s College London found exposure to nitrogen dioxide and fine and ultra-fine particulate matter during the first trimester of pregnancy delayed speech development at 18 months.
