The 2023 IPBES report, authored by 86 international experts, is the most comprehensive assessment of invasive alien species ever conducted.

It offers clear & undeniable evidence of the growing global threat of biological invasions to ecosystems, economies, and human well being. #bioinvasions

"We find that the principal drive for global warming acceleration began in about 2015, which implies that 2°C global warming is likely to be reached in the 2030s, not at midcentury" - James Hansen et al.

Honeybees have never been in danger of extinction. But scientists are finding that they can accelerate the demise of native bee populations.

The significance of this is that pigs act as "mixing vessels" for genetic exchange & re-assortment of viral genomes, which facilitates the potential emergence of novel flu strains that cause epidemics/pandemics among humans.

Biodiversity loss is continuing at an unprecedented rate, with species becoming extinct at between 100 and 1,000 times the average pre-human, or ‘background’, rate

Biodiversity conservation has an evidence problem — it’s time to fix it
Globally, more than one million species are threatened with extinction, but often interventions intended to protect biodiversity are not rooted in robust research. The field has an opportunity to change that.

Discontinuity is here. Climate and ecological disruptions are having unprecedented impacts in the lives of every person on Earth.

And, yes, that has profound security implications.

"Nature is a foundation of national security" is exactly right.

It is not an exaggerration to state that biodiversity loss should be recognized as a national security issue for every country. www.theguardian.com/commentisfre...

The false promise of de-extinction gives people (& governments) permission to act less concerned about biodiversity loss.

The 11th Duke also helped to introduce grey squirrels, which have devastated the red squirrel population."

Island land snails have experienced dramatic extinction rates, particularly in the Pacific, with habitat loss and invasive species driving declines; conservation efforts are underway to protect remaining diversity. doi.org/hbmw8n
The devastation of island land snails: Pacific leads global wave of extinctions, researchers find
A comprehensive new review paper reveals the staggering loss of biodiversity among island land snails globally. Lead author Robert Cowie of the University of Hawai'i at Mānoa's School of Ocean and Earth Science and Technology (SOEST) and co-authors note that "devastation" is not a hyperbolic term, pointing out that extinction rates on high volcanic islands commonly range from 30% to as high as 80%.

Writing with @rupertread.bsky.social about just how devastating the Government- suppressed security report is, particularly its conclusions about our food insecurity. Ministers should be helping to build our resilience to these threats, not burying the report that contains them 👇

Same here. I strongly discourage any student/early career scientist from publishing in journals like MDPI and FrontiersIn. It will only taint their CV.
True, very true. That is why I will have nothing to do with MDPI, Frontiers and Hindawi. Quote: "Now, even the most mediocre researchers receive a flood of invitations to edit one of these countless special issues, which have become a multi-million dollar business" 🧪
Thousands of scientists inflate their CVs with self-published studies that cost millions of dollars of public money
