Six AI data centers proposed for a small town of 7,000, equal to 51 Walmart Supercenters in 17 square mile area — four out of the seven town council members have resigned from their positions as town fights back

Developers have proposed building six AI data centers in Archbald, Pennsylvania, a small town with a population of 7,000. These data centers would cover 14% of the town's 17-square-mile area and are equivalent in size to 51 Walmart Supercenters. The community is pushing back due to concerns about the impact on local utilities, noise, and light pollution. The fight has led to resignations from town council members and delays in the projects, with President Donald Trump getting involved in urging hyperscalers to address community concerns.

New Jersey datacenter expansion got $77m in tax breaks to create exactly one permanent job — JPMorgan's site already scored $35m and currently employs just 25 workers

A JPMorgan datacenter expansion in New Jersey received $77 million in tax breaks to create just one permanent job, marking a high subsidy-to-jobs ratio. The expansion, which is part of a $1 billion investment, currently employs only 25 workers despite the substantial tax incentives. The Industrial Development Agency (IDA) believes the deal will benefit the local economy, projecting a $100 million infusion. While the IDA acknowledges the lack of permanent jobs, they argue that the overall economic impact justifies the subsidy. The situation highlights the need for closer scrutiny of datacenter subsidies and their true economic impact.

The company's decision to pause purchases may impact the industry's growth and reliance on corporate support. Industry experts suggest that government mandates and policies are needed to ensure the scalability of carbon removal efforts.

The quest to measure our relationship with nature

The United Nations is working on a Nature Relationship Index (NRI) to measure how well countries interact with the natural world. The NRI aims to shift the narrative from humans being destroyers of nature to fostering a green, abundant world. The index will assess three key questions: whether nature is thriving and accessible, if it is being used with care, and if it is safeguarded. The NRI will debut alongside the 2026 Human Development Report, encouraging countries to compete and improve their scores. The goal is to engage people's hopes and dreams for a better relationship with nature.
