Climate policy models usually assume people hold accurate beliefs about climate damages. A new study builds disinformation into a climate-economy model and finds that informed democratic majorities can deliver stronger carbon taxes than a politically constrained planner, but this advantage collapses abruptly once disinformation tips the majority. Late and persistent disinformation yields the most severe warming, while counter-disinformation efforts can largely restore effective policy.
The Sierra Nevada mountain range in California is as stunning as it is diverse, with storms from the Pacific Ocean dumping rain and snow on the range's western slopes while arid conditions mark much of its eastern face. David Des Marais, MIT's Amgen Career Development Associate Professor, knows the mountains well. His childhood in San Francisco was filled with hiking and camping excursions throughout the range.
Satellite L-band radiometry has transformed open-ocean salinity monitoring, but coastal retrieval remains difficult. Bright land signals leak into ocean measurements, while side lobes, imaging artifacts, radio frequency interference, and calibration errors distort brightness temperature near shore. Existing forward models also assume fully developed, wind-driven seas and often neglect fetch limits, wave age, shallow-water effects, and wave–current interactions.
Bushfire smoke is affecting Queensland urban air quality more often and more severely than previously understood, with new QUT-led research revealing bushfire-impacted hours have almost tripled in recent years, increasing health risks for communities.
With DKK 5.5 million from the Grundfos Foundation, the Danish Technological Institute is heading an initiative to develop and deploy mobile water purification units in war-torn areas of Ukraine in collaboration with the International Red Cross and several partners.
An undergraduate student developing brain-inspired computer chips which could dramatically reduce the energy needed to run artificial intelligence (AI) has secured a major national sustainability award.
"The lake surface is calm, and the still air is glorious on this cool, cloudless August morning," Iowa State University's Elizabeth Swanner wrote about a research trip to a 60-foot deep, 13-acre lake within Itasca State Park and the Mississippi River headwaters of north-central Minnesota.
Lactic acid is used in food, pharmaceuticals and the production of polylactic acid, a biodegradable polymer. It is commonly made through fermentation, which requires controlled conditions and can take considerable time, while chemical production can depend on fossil-derived feedstocks.
Several reforms to EU chemicals policy and legislation have been introduced in recent years, with the aim of promoting the green transformation. Many of these reforms also affect the pharmaceutical sector and its stakeholders. A study conducted at the University of Eastern Finland found that changes to EU chemicals legislation create both opportunities and challenges for the green transformation in the pharmaceutical sector.
The methodology, applied in Bilbao, Madrid and Caceres, has shown that socio-economic conditions and the characteristics of the urban fabric have a significant influence on vulnerability. The tool generates vulnerability maps that help determine where adaptation measures to combat heatwaves should be prioritised.
