IISD – Geoengineering at UNEA-4: Why the SDGs Require a Governance Debate Based on Precaution, Rights and Fairness

L Fuhr  (Heinrich Böll Foundation); IISD;

Geoengineering threatens global peace and security, and some technologies have significant potential to be weaponized. Research – and common sense – demonstrate clearly that the SDGs are overwhelmingly in conflict with geoengineering and its effects, particularly in being contrary to strengthening resilience and adaptive capacity to climate-related hazards and natural disasters, food security, sustainability and safety. When governments at UNEA-4 discuss a resolution on geoengineering, they need to ensure that they build on the existing consensus decisions of other UN bodies on that matter. Setting aside the false promise of geoengineering and focusing on both accelerating the energy transition and truly protecting and restoring our ecosystems so that they can act as carbon sinks, is the safest and surest way to confront the climate crisis.”

Guardian – 22 of world’s 30 most polluted cities are in India, Greenpeace says

Twenty-two of the world’s 30 worst cities for air pollution are in India, according to a new report, with Delhi again ranked the world’s most polluted capital. The Greenpeace and AirVisual analysis of air pollution readings from 3,000 cities around the world found that 64% exceed the World Health Organization’s annual exposure guideline for PM2.5 fine particulate matter – tiny airborne particles, about a 40th of the width of a human hair, that are linked to a wide range of health problems. Every single measured city in the Middle East and Africa exceeds the WHO guidelines, as well as 99% of cities in south Asia and 89% in east Asia. Since many cities, particularly in Africa, do not have up-to-date public air quality information, the actual number of cities exceeding PM2.5 thresholds is expected to be much higher, the report authors said. “

Cfr a tweet from Robert Marten: “Are Asian cities the most polluted? Or are these cities simply doing a better job of measuring air pollution?”

Vox – Forget cars. We need electric airplanes.

The race is on to build batteries big enough for planes to fly on clean electricity.”

But still decades away for fully electric airliners. So for the time being, we’ll have to think of something else. As in: cutting flying drastically, taxing it heavily (especially for billionaires :), etc ).

Guardian – Heatwaves sweeping oceans ‘like wildfires’, scientists reveal

The number of heatwaves affecting the planet’s oceans has increased sharply, scientists have revealed, killing swathes of sea-life like “wildfires that take out huge areas of forest”….”
