ON OLD PENNY

corner_wall - write in wiki!

library and more_topics

admin micro blog

And main topic climate_v2

Before the world started taking measures to reduce emissions, it

was useful to make calculations about the impact & measures like EVs

and solar panels. In 2012 awareness was quite large, and for the first time

scientists were able to link individual extreme weather events to climate change.

In 2019 there was Greta Thunberg and the million people march around the globe.

There was still some time, but by 2022 everything changed. We were getting so

close to breaking through the Paris 2015 limit of 1.5oC increase, that change needed

was getting too big and too fast. It was too late for a 'reasonable' revolution.

By may 2024 we broke through +1.5oC and lots of governments and companies are

scrapping plans and promises to cut emissions.

.

In this time awareness is not the problem and big calculations are useless. Because … The

world waited too long, made some promises, and that's all. Activism by admin dies here.

Earth may have breached seven of nine planetary boundaries, health check shows

Ocean acidification close to critical threshold, say scientists, posing threat to marine ecosystems and global liveability

1. # Ocean acidification # is approaching a critical threshold”, particularly in higher-latitude regions, says the latest report on planetary boundaries. “The growing acidification poses an increasing threat to marine ecosystems.”

Oceans face ‘triple threat’ of extreme heat, oxygen loss and acidification

The report, from the Potsdam Institute for Climate Impact Research (PIK), builds on years of research showing there are nine systems and processes – the planetary boundaries – that contribute to the stability of the planet’s life-support functions.

Thresholds beyond which they can no longer properly function have already been breached in six.

2. # Climate change #,

3. the introduction of # novel entities #,

4. change in # biosphere integrity # and

5. # modification of biogeochemical flows # are judged to be in high-risk zones,

while planetary boundaries are also transgressed in

6. # land system change # and

7. # freshwater change #0but to a lesser extent.

All have worsened, according to the data.

8. # Stratospheric ozone depletion # has remained stable, however,

9. and there has been a slight improvement in # atmospheric aerosol loading # , the research says.

Planetary boundary science was pioneered in 2009 by Johan Rockstrom, the director of the PIK, and others
