The National Climate Assessment, released the day after Thanksgiving, highlights the risks to which federal policymakers are exposing the country — including very pointedly the Midwest — by attempting to roll back limits on greenhouse gas emissions that contribute to climate change, says an expert on environmental policy at Washington University in St. Louis.
Researchers in the School of Engineering & Applied Science have discovered a new, natural law that sheds light on the fundamental relationship between coated black carbon and light absorption.
Under warming conditions, Arctic wolf spiders’ tastes in prey might be changing, according to new research by biologist Amanda Koltz in Arts & Sciences — initiating a new cascade of food web interactions that could potentially alleviate some impacts of global warming.
A team at Washington University in St. Louis has created a bacteria that uses photosynthesis to create oxygen during the day, and at night, uses nitrogen to create chlorophyll for photosynthesis. This development could lead to plants that do the same, eliminating the use of some — or possibly all — man-made fertilizer, which has a high environmental cost.
Thirty years ago this month, the term global warming became part of our popular conversation. Doctoral candidate Andrea Godshalk from the Sam Fox School of Design & Visual Arts reflects on the recent Saint Louis Climate Summit and the challenge of re-imagining key infrastructure, systems and values.
The findings, reported in the journal Science, contain positive implications for the survival of the West Antarctic Ice Sheet, which scientists had previously thought could be doomed because of the effects of climate change, according to study co-author Douglas Wiens of Arts & Sciences.
Warmer summer and fall seasons and fewer winter freeze-thaw events have led to changes in the relative numbers of different types of bugs in the Arctic, says Amanda Koltz, a postdoctoral fellow in Arts & Sciences. The study relies on the longest-standing, most comprehensive data set on arctic arthropods in the world today: a catalogue of almost 600,000 flies, wasps, spiders and other creepy-crawlies collected at the Zackenberg field station on the northeast coast of Greenland from 1996-2014.
Washington University faculty and students will moderate panels at the Saint Louis Climate Summit, hosted by Saint Louis University. Students, faculty and staff can attend an evening with Bill Nye of “Science Guy” fame and environmentalist Carl Pope on April 23 for free by showing their IDs at the ticket booth.
S. George Philander, one of the world’s leading experts on climate and the interactions between the ocean and atmosphere, will deliver two talks March 28 and 29 as part of the McDonnell Distinguished Lecture Series, sponsored by Washington University in St. Louis’ McDonnell Center for the Space Sciences.
President Donald Trump has made the decision to pull the U.S. out of the 2015 Paris climate agreement, a move that that cannot be justified on the stated grounds for withdrawal, says an expert in environmental law at Washington University in St. Louis.
