Meet Climate Solutions Catalyst Cohort 1 - Dr Joanna Sadler (Edinburgh): Turning Waste Into Wealth
Many next-gen plastics, marketed as biodegradable, persist in the environment or only break down under specific conditions. Dr Jo Sadler & team @edinburgh-uni.bsky.social are exploring how microbial upcycling can turn next-gen polymer waste into high-value chemicals โฌ๏ธ www.youtube.com/watch?v=xYCV...

The significant climate and health risks associated with airport expansion cannot be ignored.
With limited scope to reduce emissions through technology in the near term, growth in the sector would put the UKโs ability to meet its climate commitments over the coming decades at risk.

๐ Airport expansion could also negatively affect the health of local communities.
Recent research shows exposure to higher levels of noise is associated with worsened heart function and increased mortality risk.

1๏ธโฃ Measuring trace metals, algae & cyanobacteria to understand the effect of glacier retreat on water quality
2๏ธโฃ Assessing the impacts of water quality on the ecosystem and human health through an interactive online tool.

๐ง Water is a fundamental need to sustain life on Earth. However, human activities are degrading water quality and severely threatening water security.
48% of wastewater is released into the environment and polluted rivers have reduced economic growth by 1.4-2.5% in downstream regions worldwide๐งต

โ ๏ธ These changes threaten water security and billions of people living in mountain regions.
However, data on how climate change is reshaping water quality is scarce in mountain regions such as the Andes, making policy actions and solutions difficult to take.

โฐ๏ธ Climate change is now also threatening freshwater bodies with good water quality, such as those in high mountain areas.
Air temperature has increased by about 0.3ยฑ0.2ยฐC per decade in mountain regions, accelerating the retreat of snow cover in some places and causing droughts or floods in others.

Polluters on trial: How climate science is rocking the courtroom
Attribution science is enabling climate victims to sue the worldโs top polluters for damages and the first successful case may not be very far away, writes Chloรฉ Farand.
It now seems inevitable that a major emitter will be held responsible for their contribution to the climate crisis.

Attribution science is now increasingly finding itself in the courtroom, supported by @imperialcollegeldn.bsky.social researchers like Dr Noah Walker-Crawford (also at @granthamlse.bsky.social) and @frediotto.bsky.social โฌ, co-founder of @wwattribution.bsky.social and Prof. at @ic-cep.bsky.social.

๐ฏThe court ruled that attribution science can, in principle, establish legal causation.
That means future cases can succeed, if supported by the right science.
