In 1994 a parks officer abseiled into a sandstone canyon northwest of Sydney and found a stand of conifers matching a 90-million-year-old fossil pollen record. The Wollemi pine, down to fewer than 100 adults, has been protected by classified coordinates, helicopter access and a 2019 firefighting operation that saved every mature tree.
After the 1991 Bay of Bengal cyclone killed roughly 138,000 people in a single night, Bangladesh chose to plant hundreds of kilometres of salt-tolerant mangrove forest along its delta coast. The reasoning was physical, ecological and economic — and satellite imagery now shows the result.
Pando, a single quaking aspen clone in Utah's Fishlake National Forest, covers 106 acres with 47,000 genetically identical trunks connected by one root system — and weighs an estimated 6,000 tonnes.
NASA's Parker Solar Probe now skims to within 6.1 million kilometres of the Sun at 692,000 km/h — fast enough to cross the United States in 20 seconds — protected by a carbon-composite heat shield just 11.4 centimetres thick.
A typical fair-weather cumulus holds around 500 tonnes of water — the mass of 100 elephants — dispersed as trillions of 20-micron droplets held aloft by rising warm air. Here is the physics, and what a new centimetre-scale lidar just revealed about cloud tops.
