Learning From History To Help Guide the Future of NYC’s Crucial Watershed – State of the Planet

Ashokan Reservoir, October 2024. Photo: Agnes Laylicha, School of International and Public Affairs and Columbia Climate School Increasing climate variability is threatening the water supply and exposing the fragility of the New York City watershed, which hosts the largest unfiltered water supply in the world. Columbia Climate School students had the opportunity to learn about […]

Improving U.S. Coastal Protection and Resilience – State of the Planet

Hurricanes Helene and Milton have left massive damage and loss in communities across the Southeast and Gulf of the U.S. Yet this may just be the beginning. With near record-warm ocean temperatures in the Atlantic, the National Oceanic and Atmospheric Administration (NOAA) has predicted a dangerous hurricane season with a record number of storms. Millions […]

Glacier Melt Leads to Redrawing of the Italian-Swiss Border – State of the Planet

Glaciers have historically determined the boundary between Italy and Switzerland in the Alps. Now, their melting has led the two countries to redraw a small section of their border over the past year and revived concerns of how climate change might impact mountain communities around the world in the coming years. Glaciers form the borders […]

The truth behind Europe’s floods

Media coverage has criticised government failures to adequately prepare and react to Valencia’s floods – from building in flood-prone areas, to the dismantling of the Valencian Emergency Unit, to the delayed disaster response. These critiques are right – but they miss the crux of the issue. When we pave over forests to expand our cities, drain coastal wetlands […]

Four Value Propositions for Climate Action Under a New Presidential Administration – State of the Planet

There’s no mincing words: The forthcoming transition of United States presidential administrations is sending shockwaves through the climate advocacy community.  Many say that it highlights an almost definitive exponential increase in emissions. Carbon Brief suggests an additional 4 billion tons of emissions by 2030; the MIT technology review asserts this is an emissions trajectory we […]

Israeli bombings destroy lives – and nature

These attacks, deemed war crimes by international NGOs, have also destroyed 1,900 hectares of farmland and rendered another 1,200 hectares abandoned.   Lebanon has lost 47,000 olive trees, thousands of animals in livestock, and 1,200 hectares of forest. “Olive trees have always been targeted because they are deeply tied to the land and its people,” says […]

Unexplained Heat-Wave ‘Hotspots’ Are Popping Up Across the Globe – State of the Planet

Earth’s hottest recorded year was 2023, at 2.12 degrees F above the 20th-century average. This surpassed the previous record set in 2016. So far, the 10 hottest yearly average temperatures have occurred in the past decade. And, with the hottest summer and hottest single day, 2024 is on track to set yet another record. All […]

A coordinated kinase and phosphatase network regulates Stu2 recruitment to yeast kinetochores

Cells coordinate diverse events at anaphase onset, including separase activation, cohesin cleavage, chromosome separation, and spindle reorganization. Regulation of the XMAP215 family member and microtubule polymerase, Stu2, at the metaphase-anaphase transition determines a redistribution from kinetochores to spindle microtubules. We show that cells modulate Stu2 kinetochore-microtubule localization by Polo-like kinase1/Cdc5-mediated phosphorylation of T866, near the […]
