There are some obvious ways that climate change can be costly to municipalities, such as damage from destructive storms. But a team of researchers delved into the multiple ways that climate change creates fiscal hazards for cities and towns by looking at Florida, a state that has been hard-hit by climate change and faces a challenging future.

In a study, they found over half of Florida’s 410 municipalities will be affected by 6.6 feet of sea-level rise, and that almost 30% of all local revenues currently generated by these 211 municipalities come from buildings that are expected to be chronically flooded by the end of the century. “If cities don’t adapt, increasing damage from climate-driven disasters and sea-level rise will create a vicious fiscal cycle, eroding local tax bases and driving up services costs – which in turn leaves less money for adaptation,” they write.

Many people, like myself, began to learn more about the importance of antiviral drugs during the height of the COVID-19 pandemic. But the body itself can make antiviral molecules, writes University of Michigan biochemist Neil Marsh. He explains the science behind how antiviral proteins in cells respond to viral infections and work with the rest of the immune system.

You may have heard that Lego abandoned plans to build its iconic blocks from recycled plastic. A group of sustainability and supply chain researchers explains how Lego’s decision reflects how the most significant part of a company’s carbon footprint often lies in its supply chain, which may become more clear as carbon disclosure regulations take hold. “We may see more instances where well-intentioned sustainability efforts run into uncomfortable truths,” they write.

Your immune system makes its own antiviral drug − and it’s likely one of the most ancient

Neil Marsh, University of Michigan

The human body has been making antivirals for eons, long before scientists did. A protein in your cells called viperin produces molecules that work similarly to the COVID-19 antiviral remdesivir.

Lego’s ESG dilemma: Why an abandoned plan to use recycled plastic bottles is a wake-up call for supply chain sustainability

Corporate supply chains are riddled with high, uncounted emissions, as Lego discovered. New regulations mean more companies will face tough, sometimes surprising, choices.

What is seawater intrusion? A hydrogeologist explains the shifting balance between fresh and salt water at the coast

Holly Michael, University of Delaware

Saltwater intrusion is bad for human health, ecosystems, crops and infrastructure. Here’s how seawater can move inland, and why climate change is making this phenomenon more frequent and severe.

How a disgruntled scientist looking to prove his food wasn’t fresh discovered radioactive tracers and won a Nobel Prize 80 years ago

Some Nobel Prize-winning ideas originate in strange places, but still go on to revolutionize the scientific field. George de Hevesy’s research on radioactive tracers is one such example.

Glacial lake outburst floods in Alaska and the Himalayas show evolving hazards in a warming world

Alaska has at least 120 glacier-dammed lakes, and almost all have drained at least once since 1985, a new study shows. Small ones have been producing larger floods in recent years.

Rising oil prices, surging inflation: The Arab embargo 50 years ago weaponized oil to inflict economic trauma – sound familiar?

Russia’s 2022 invasion of Ukraine reprised the risks of energy weaponization, but the oil landscape today and energy security itself are changing.
