Model shows extinction cascades caused by land use and climate change will wipe out more than 25% of world biodiversity
A new tool developed by European and Australian scientists enabling unparalleled modeling of interconnected species loss shows cascading extinctions are unavoidable, and that the Earth will lose some 10% of its animals and plants by 2050, rising to 27% by 2100.
The findings are published in the journal Science Advances.
Using one of Europe’s most-powerful supercomputers, European Commission scientist Dr. Giovanni Strona also of the University of Helsinki and Professor Corey Bradshaw of Flinders University used the tool to create synthetic Earths complete with virtual https://phys.org/tags/species/ and more than 15,000 food webs https://phys.org/tags/food+webs/ to predict the interconnected fate of species that will likely disappear from the ravages of climate and land-use changes.
The tool presents a grim prediction of the future of global diversity, confirming beyond doubt that the world is in the throes of its 6th mass https://phys.org/tags/extinction/ event.
The two scientists say past approaches to assessing extinction trajectories over the coming century have been stymied by not incorporating co-extinctions—that is, species that go extinct because other species on which they depend succumb to climate change and/or changes to the landscape. |Read more https://phys.org/news/2022-12-extinction-cascades-climate-world-biodiversity.html|

Financial intelligence agency tracking signs of homegrown terrorism financing:
Those three main themes emerge from the Financial Transactions and
Reports Analysis Centre of Canada’s review of its intelligence
disclosures to police and security agencies from January 2019 to October
2022 related to the funding of terrorist activity.
The federal centre, known as Fintrac, is drawing on the analysis to
help banks and others that handle large sums to better spot shady
transactions linked to terrorism.
For instance, Fintrac says in a newly published operational alert,
transaction details might include references to words, phrases or
numbers linked to violent extremist groups or symbols.
The centre zeroes in on cash linked to terrorism, money laundering
and other crimes by sifting through data from banks, insurance
companies, securities dealers, money service businesses, real estate
brokers, casinos and others.
