Good morning. Here's what's going right.

High Court Blocks a 22-Year Extension of the Mount Pleasant Coal Mine
On 7 October 2026, Australia's High Court dismissed MACH Energy's appeal and left standing a ruling that approval of the Mount Pleasant coal expansion was invalid. The Hunter Valley community group that brought the case argued planners never considered how to minimise emissions from burning the exported coal — 98 percent of the project's greenhouse gases. The company had wanted to run the mine until 2048 and extract an additional 406 million tons.
It is the first climate case decided by Australia's highest court. It is not a permanent ban. MACH says it will look for another lawful path, and the current approval still runs toward December 2026. What the judgment does is refuse the pretence that coal burned overseas is someone else's weather.
In Brief
👁️ El Salvador Eliminates Trachoma, the Leading Infectious Cause of Blindness
WHO has validated El Salvador as the first country in Central America to eliminate trachoma as a public health problem. Surveys from 2023 to 2026 found no active transmission in the communities assessed. PAHO recognised the milestone on 29 September alongside other elimination achievements in the Americas.
🔬 The Medicine Nobel Honours a Light Switch for Single Nerve Cells
Karl Deisseroth, Peter Hegemann and Georg Nagel share the 2026 prize for optogenetics. A protein from a light-seeking alga became a way to turn individual nerve cells on or off in a living brain. It is a research tool, not an approved therapy.
🌳 London Is Planning a 200 Kilometre Ring of Trees
CPRE London launches the London Tree Ring on 15 October: a 25-year green corridor around the outer boroughs. Ten demonstrator sites are already planted, including 1,500 trees on the south-west edge. The ring itself is not finished. That is the honest part.
⚖️ Navi Pillay Wins the Nobel Peace Prize
The Norwegian Nobel Committee awarded the 2026 Peace Prize to South African jurist Navi Pillay for her work on international law, from apartheid-era defence work to the Rwanda tribunal, the ICC, and the International Court of Justice. Israel condemned the choice because of her UN commission's Gaza findings, which Israel rejects. The citation is a career in court, and the dispute is part of the record.
📊 Progress by Numbers
- 98 percent of the Mount Pleasant project's emissions were scope 3 — coal burned overseas
- 183,000 giant tortoises now estimated on Aldabra, up from fewer than 1,000 in the 19th century
- 11.2 gigawatts of renewables on small islands, past a 2030 target five years early
- 1.28 hours to the start of relief in a Lancet trial of an oral hereditary angioedema drug, versus more than 12 hours on placebo
- 23.5 percent certified efficiency on a 30-centimetre perovskite solar submodule
💡 One Thing You Can Do
If you live on the edge of a city, ask who is actually watering the new trees. London's ring only works if schools, landowners and neighbours keep the saplings alive after the launch photo. A stake and a dry July are the whole policy.
