Video: The Tipping Points of Climate Change and Where We Stand in 2024 | Johan Rockström (TED talk)

I came across this TED talk by accident, produced mid August 2024.

"We're nearly halfway through the 2020s, dubbed the most decisive decade for action on climate change. Where exactly do things stand? Climate impact scholar Johan Rockström offers the most up-to-date scientific assessment of the state of the planet and explains what must be done to preserve Earth's resilience to human pressure."

This 20 minute video really is worth watching to inform you to step up climate action.

PFAS, synthetic turf and a new planetary boundary proposed and being exceeded


Very concerning. Increasing production and use of Forever chemicals, that is, the thousands of chemicals in the PFAS class: Per- and Polyfluoroalkyl Substances. These are not natural chemicals, and they do not break down in the environment. The chemicals are widely used. According to the Department of Health they are not manufactured in Australia, although plenty of products that use PFAS are imported.

PFAS is spread widely through water pollution and oceans and as aerosols in the atmosphere contaminating soils. PFAS chemicals are found very widely across the earth in rainfall. So, our water resources  are now contaminated.

My attention was drawn to this Euronews article. It sums up the recent scientific findings and outlines the issues: Rainwater everywhere on Earth unsafe to drink due to ‘forever chemicals’, study finds

Fluorine signatures and PFAS chemicals have been found in synthetic turf matting and fibers in the USA and in Sweden. With the study in Sweden the researchers say the presence of PFAS chemicals "we believe these results to be broadly translatable to Artificial turfs globally".
