Published recently in the journal Sensors, a new study by Berkeley Lab air quality scientists tested four models of low-cost air quality monitors during actual wildfire pollution events and found that their readings of PM2.5 – or particulate matter under 2.5 microns, which has been linked to respiratory and cardiovascular issues – were consistently higher than the reference monitor used by the regulatory agencies; however, since each monitor had a relatively consistent response to the smoke, it is possible to use the readings to estimate true PM2.5 levels. Overall, the researchers concluded that the monitors can provide actionable information.

Some governments are counting on planted forests as offsets for greenhouse gas emissions—a sort of climate investment. But as with any investment, it’s important to understand the risks. If a forest goes bust, researchers say, much of that stored carbon could go up in smoke. Forests can be best deployed in the fight against climate change with a proper understanding of the risks to that forest that climate change itself imposes.

Climate change has contributed to the increase in the number of wildfires in the Arctic where it can dramatically shift stream chemistry and potentially harm both ecosystems and humans. Researchers at the University of New Hampshire have found that some aftereffects, like decreased carbon and increased nitrogen, can last up to five decades and could have major implications on vital waterways.

A new study led by the University of Delaware’s Pinki Mondal recommends that in addition to using large swaths of coarse satellite data to evaluate forests on a national scale, it is important for countries to prioritize areas such as national parks and wildlife refuges and use finer scale data in those protected areas to make sure that they are maintaining their health and are being reported on accurately.

Lawrence Livermore National Laboratory (LLNL) scientists have identified a robust suite of technologies to help California clear the last hurdle and become carbon neutral – and ultimately carbon negative – by 2045. This groundbreaking study, “Getting to Neutral: Options for Negative Carbon Emissions in California,” was conducted as part of LLNL’s expansive energy programs work and the Laboratory’s Carbon Initiative. The goal of the initiative is to identify solutions to enable global-scale CO2 removal from the atmosphere and hit global temperature targets.
