Researchers from Oregon State University conducted a study on the threat of climate change to wild animal species and biodiversity. The study, published in BioScience, assessed 70,814 species from 35 existing classes and assessed climate threat to wild species.

Data centers—such as those used by Microsoft, Amazon, Google, and Meta—are crucial for data connectivity, storage, and processing. However, these pose concerns given their large real estate footprint and energy consumption.

A recent study by researchers at the University of Plymouth, UK, has found that a portion of the world’s oceans have darkened from 2003 to 2022. This is concerning because marine life depends on light for hunting, migration, and reproduction.

The World Health Organization (WHO) has been publishing annual reports on world health statistics since 2005, with a focus on health-related sustainable development goals (SDGs) since 2016.
