35 Years of Harnessing the Power of Geospatial Data for Decision Making – State of the Planet

The Climate School’s Center for International Earth Science Information Network (CIESIN) is celebrating its 35th year since its founding as an independent nonprofit in 1989, and its 25th year housed at Columbia University. These anniversaries come with another milestone: a new name. As of today, CIESIN will now stand for the Center for Integrated Earth […]

Europe’s Plan to Achieve Net-Zero Emissions in a Complex World – State of the Planet

Last week, the Columbia Climate School Signature Speaker Series welcomed Hans Bruyninckx, former executive director of the European Environmental Agency, to talk about “The European Green Deal: The pathway to net-zero emissions in a complex global context.” Bruyninckx gave a primer on the current challenges and opportunities the E.U. is facing when it comes to climate […]

Illegal oil drilling stopped at Surrey site

The developer of the Horse Hill oil and gas project has halted oil extraction, four months after planning permission was quashed by the Supreme Court. Surrey County Council gave planning permission four new oil wells and 20 years of oil production at Horse Hill in 2019.  However, following legal action bought by local resident Sarah Finch […]

Dinosaurs Thrived After Ice, Not Fire, Says a New Study of Ancient Volcanism – State of the Planet

201.6 million years ago, one of the Earth’s five great mass extinctions took place, when three-quarters of all living species suddenly disappeared. The wipeout coincided with massive volcanic eruptions that split apart Pangaea, a giant continent then comprising almost all the planet’s land. Millions of cubic miles of lava erupted over some 600,000 years, separating […]

Navigating Challenges, Tools and Strategies for a Net-Zero Future – State of the Planet

The Columbia Climate School is excited to announce a hybrid professional learning workshop this fall: Climate Finance: The Challenges of Transitioning from Funding Climate Change to Funding Net-Zero. Building on the momentum of a successful spring session, this workshop examines the challenges and opportunities of mobilizing trillions of dollars in climate finance to meet the […]

Keir Starmer: planet harmer?

A majority of British voters believe Sir Keir Starmer shows no greater commitment to protecting the environment as the Labour prime minister than the previous Conservative government. Some two-thirds believe Starmer’s approach to the environment is no different to the one taken under Rishi Sunak’s previous administration. Ahead of next week’s budget, significantly more than […]

Mammals didn’t walk upright until late—here’s what fossils reveal

For over a century, scientists have puzzled over a fundamental mystery in our evolutionary history: how did mammals go from sprawling like lizards to striding like cats and dogs? This transition — from a sprawled stance (like a lizard) to an upright (parasagittal) posture — marked a pivotal moment in mammal evolution. While the earliest […]

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 […]
