By ScienceAdvisor.  Excerpt: Every day, aerosols form in clouds and swirl throughout the turbulent atmosphere. Aerosols, especially those under 10 nanometers, can be dangerous to humans when inhaled because of how easily they enter body tissues; estimates suggest exposure to fine aerosols causes around seven million premature deaths annually. Researchers wanted to see if climate change may alter how aerosol production occurs. Scientists have generally assumed that hot temperatures should hinder the formation of new aerosols.... To check, a team took measurements of nanoparticles and trace gases during a heat wave in central Texas. ...To their surprise, the researchers reported this week in  Science  that  at conditions nearing 40ºC, new particles formed in droves . ...gaseous organic acids, an important precursor to new particle formation, which come from industry sources like traffic and biological sources like oak and pine trees. ...fatty acids in nanoparticle form...

By Saima May Sidik , Eos/AGU.  Excerpt: Drained peatlands in Finland can become carbon sinks within just 15 years of restoration, suggests a study published in  Restoration Ecology .  The findings  are a stark contrast to another recent publication that suggests the switch from source to sink can take  hundreds of years . Finland will submit a biodiversity restoration plan to the European Commission this September, and what to do about the country’s  5 million hectares  of drained peatland will likely be a hot topic.  Teemu Tahvanainen , the author of the new study and a plant ecologist at the University of Eastern Finland (Itä-Suomen Yliopisto), said the upcoming deadline motivated him to add to the conversation....  Full article at https://eos.org/articles/restored-peatlands-could-become-carbon-sinks-within-decades . 

By Amanda Holpuch , The New York Times.  Excerpt: Manufacturers will no longer get a credit toward vehicle emissions standards by installing engines that automatically stop at red lights. ...The start-stop feature is meant to save fuel and reduce emissions, but the Trump administration rejected the scientific finding that the government used to support vehicle emission reduction regulations, making it possible to eliminate the credit. ...Research shows that start-stop reduces fuel use and cuts emissions. Depending on driving conditions, stop-start improved fuel economy between 7.27 and 26.4 percent during testing, according to a  2023 technical paper  by SAE International, an organization formerly known as the Society of Automotive Engineers....  Full article at https://www.nytimes.com/2026/02/15/business/energy-environment/epa-tax-credits-stop-start-ignition-cars.html . 

By Tom Chivers , SEMAFOR.  Excerpt: Renewables are being deployed aggressively across much of the world even as the US, historically the world’s biggest emitter, overturned a landmark domestic climate ruling. ...Elsewhere in the world, however, green technology is being implemented at pace: Africa’s solar capacity expanded 17% last year, with 20 of the continent’s nations  setting import records , and data this week showed that China’s emissions  may already be falling  thanks in large part to its huge outlay on clean power. Meanwhile, the International Energy Agency said renewables and nuclear will account by  half of global power supply by 2030 ....  Full article at https://www.semafor.com/article/02/13/2026/renewables-soar-globally-despite-us-climate-pullback . 

By Eric Niiler , The New York Times.  Excerpt: The U.S. National Science Foundation said on Thursday that the management and operations of a supercomputer used by more than 4,000 climate and weather scientists across the country would be transferred from a leading research lab to an undisclosed third party. ...Science foundation officials said stewardship of the supercomputer, located at a National Center for Atmospheric Research [NCAR] facility in Cheyenne, Wyo., would “transition to a third-party operator” but declined to give details about the new operator or the timeline. The national center...at its headquarters in Boulder, Colo., and has managed the Cheyenne facility since it opened in 2012. The announcement took many scientists by surprise. ...The center, founded in 1960, is responsible for many of the biggest scientific advances in humanity’s understanding of weather and climate. Its research aircraft and sophisticated computer models of the Earth’s atmosphere and oceans ar...
