Human activity heating the planet

As a frightening storm Melissa pounds Jamaica and moves agonisingly slowly toward poverty stricken Cuba, we know we are all responsible for the cause of these increasingly more common nightmare scenarios:

Why Hurricane Melissa is one of the strongest Atlantic storms ever

The monster hurricane pummelling Jamaica is powered by abnormal sea surface temperatures in the Caribbean, which were made at least 500 times more likely by global warming

The Gulf Stream System may collapse:

Weakening Gulf Stream System Could Unleash Global Chaos

By Potsdam Institute for Climate Impact Research (PIK)September 13, 2025

The AMOC, Earth’s ocean “conveyor belt,” may collapse after 2100 under high-emission scenarios, according to new simulations. Triggered by failing deep convection in the North Atlantic, the breakdown would lock in feedback loops that lead to extreme European winters and global weather disruption.

Retired, living in the Scottish Borders after living most of my life in cities in England. I can now indulge my interest in all aspects of living close to nature in a wild landscape. I live on what was once the Iapetus Ocean which took millions of years to travel from the Southern Hemisphere to here in the Northern Hemisphere. That set me thinking and questioning and seeking answers. In 1998 I co-wrote Millennium Countdown (US)/ A Business Guide to the Year 2000 (UK) see https://www.abebooks.co.uk/products/isbn/9780749427917
