Scientists unveil groundbreaking tool that could change how we prepare for weather disasters: 'More knowledge at our disposal than ever before'
Expert climate scientists at Columbia University have developed a new interactive tool that can help predict natural disasters so the government can prepare for them. They led the U.S. Natural Hazards Climate Change Projections project with a group of researchers to create an interactive dataset with maps and graphs, according to a post by the Earth Institute at Columbia University in The dataset can track and predict climate change-fueled extreme events on a county level. These detailed estimates provide vital information to governments, city officials, disaster relief organizations, and residents. Better preparation for natural disasters is good for the environment and can mean less expensive damage and fewer injuries and deaths. In their testing, the researchers found that San Diego and Washington State are both at a high risk for wildfires, and it could get worse. North Dakota and South Dakota could also see an increased risk for wildfires, and the East Coast may soon see more tornadoes. "While the challenges of climate change and disasters may seem overwhelming, it is also important to note that we have more knowledge at our disposal than ever before," said Jeffrey Schlegelmilch, a climate professor at the Columbia Climate School, per "By working across sectors and engaging partnerships like this, we can provide data that is empirically rigorous and immediately relevant to stakeholders outside of academia. This helps to foster better decisions, better investments and better resilience for our communities." The team released the dataset tool in April as open source and available to everyone. It's an important resource in a time when the Trump Administration is cutting funding to FEMA and taking down governmental agency tracking websites. "By making this data available in an accessible format, we aim to support not just climate scientists and risk modelers, but also urban planners, emergency managers and researchers in other fields, like economics or human mobility," said Simona Meiler, a postdoctoral climate researcher at Stanford University, per What would you do if natural disasters were threatening your home?

QuantAQ Launches MODULAIR-UFP: Ultrafine Particle Monitoring for Outdoor Applications
The outdoor-ready ultrafine particle monitor offers real-time data, meteorological insights, and long-term deployment capability CAMBRIDGE, Mass., May 20, 2025 (GLOBE NEWSWIRE) -- QuantAQ, a leader in air quality sensing, today announced the launch of the MODULAIR-UFP, a new sensor built to measure ultrafine particles (UFPs) in outdoor environments, enabling researchers, regulators, and communities to access new data for air quality monitoring. Designed to operate outside the lab and in long-term installations, the MODULAIR-UFP measures total particle number concentrations from 0 to 100,000 particles per cubic centimeter (p/cm³) with little to no maintenance for extended periods of time. 'Until now, ultrafine particle monitoring has been highly constrained and difficult for long-term outdoor uses,' said David Hagan, CEO and Co-founder of QuantAQ. 'The MODULAIR-UFP brings these critical measurements into the field with precision, reliability, and ease.' Each MODULAIR-UFP is equipped with a Gill® Weather Station, adding detailed meteorological measurements—including wind speed, wind direction, temperature, and humidity—to help contextualize pollution sources. This pairing provides a new level of resolution for understanding local air quality dynamics, particularly in complex urban and industrial environments. 'With its compactness and portability, the MODULAIR-UFP opens up exciting new research possibilities,' said Dr. Dan Westervelt, Associate Research Professor at Columbia Climate School's Lamont-Doherty Earth Observatory and QuantAQ customer. 'We are particularly looking forward to understanding emissions of ultrafine particles near a major New York City highway as a function of vehicle type, fuel quality, driving conditions, and vehicle age.' Unlike other UFP solutions on the market, the MODULAIR-UFP uses a water-based, pulsed condensation particle counter (CPC). The sensor is compact, easy to install, and designed for low power consumption. To minimize downtime, the device proactively alerts users when the internal water reservoir is low, allowing maintenance teams to refill while minimizing interruptions to data collection. The MODULAIR-UFP also connects to the QuantAQ Cloud™ platform, enabling remote, real-time access to high-resolution data across single or multiple sites. Whether for researchers studying near-roadway exposure, city agencies tracking pollution hotspots, or community groups advocating for cleaner air, the MODULAIR-UFP empowers users to monitor UFP levels with flexibility and control.

Why too much carbon dioxide harms the planet
Carbon dioxide may be a naturally occurring substance on Earth, but too much of its presence has contributed to global warming, climate scientists say. Carbon dioxide, known by the chemical formula CO2, is a gas produced by various natural processes, including respiration in animals and plants, volcanic eruptions, wildfires and the decay of organic matter. But human activity since the 1800s, namely the use of fossil fuels for energy, is overwhelming the planet's natural carbon sinks, such as oceans and forests. Therefore, the heat-trapping gas causes global temperatures to rise as more of it accumulates in the Earth's atmosphere. "CO2 is rising right now because of the emissions that we're putting into the atmosphere, and it's rising very rapidly," Bärbel Hönisch, professor of earth and environmental sciences at the Columbia Climate School's Lamont-Doherty Earth Observatory, told ABC News. "And carbon dioxide is a greenhouse gas, and so it heats the atmosphere." But the invisible gas is also critical for life on Earth. Plants breathe it in, and humans breathe it out. The goal of climate mitigation isn't to remove CO2 from the atmosphere completely, but to even out the unnatural surplus instead, said ABC News Chief Meteorologist and Chief Climate Correspondent Ginger Zee. "We want to get back to the natural amount of CO2," Zee said. The consequences of extra CO2 in the atmosphere extends beyond the climate itself. As excess greenhouse gases heat the planet, the ocean becomes more acidic, impacting marine life, Hönisch said. In addition, climate change is fueling rapid growth of certain types of algae, further collapsing ecosystems, Hönisch added. "Climate is a combination of different components that must be just right for life to exist on our planet," she said. Humans have injected more than 1.5 trillion tons of CO2 into the atmosphere since the Industrial Revolution, when the use of fossils fuels began to skyrocket, according to the Global Carbon Budget. Historical levels of climate change are determined by a number of processes. Samples of ice, lake and seafloor cores indicate how much carbon dioxide existed at different periods on the planet. In addition, more than six decades of CO2 measurements have been taken at the Mau Loa Observatory on Hawaii's Big Island, home to the largest active volcano in the world. The Keeling Curve, a graph that plots concentrations of CO2 in the atmosphere over time, uses measurements taken at Mau Loa Observatory, starting in 1958. In 2024, CO2 levels in Earth's atmosphere reached the highest ever recorded, according to the National Oceanic and Atmospheric Administration. Curbing the emissions of greenhouse gases from fossil fuel use is key for limiting the impacts of a warming world, such as more frequent and intense extreme weather events and rising sea levels, climate scientists say.

Fastest sinking city in the US is revealed in new study and it's not in Florida
A new study reveals that one major U.S. city is sinking faster than any other—and it's not in the Sunshine State. Researchers from the Columbia Climate School's Lamont-Doherty Earth Observatory published their findings in the Nature Cities journal on Thursday. The study focused on the 28 most populous cities across the country, each home to more than 600,000 Americans. Recent satellite data was used to monitor land movement down to the millimeter. In a staggering twist, the study's authors found that in 25 of the cities, two-thirds or more of their land was sinking. All of the 28 cities experienced some degree of land subsidence. One city had sunk lower than any other: Houston. According to the study, approximately 40 percent of Houston's area subsided more than five millimeters per year, and about 12 percent was sinking at double that rate. Some localized spots were found to be sinking as much as 50 millimeters per year. Other major Texas cities were also found to be sagging deeper into the earth. Dallas and Fort Worth were found to be experiencing subsidence at rates above three millimeters per year in 70 percent of their total areas. Ten percent of the area in Chicago and New York City was also found to be sinking at a rate of three millimeters per year. Researchers said about 34 million people—about 10 percent of the U.S. population—are in the subsidence zones. More than 29,000 buildings in the cities analyzed were found to be at very high risk of damage. Factors such as groundwater pumping and oil extraction are causing land to cave in on itself, which poses an infrastructure risk in major urban areas. Researchers noted that buildings can be 'silently' compromised over time, with damage only potentially noticeable when it is 'catastrophic. " 'Unlike flood-related subsidence hazards, where risks manifest only when high rates of subsidence lower the land elevation below a critical threshold, subsidence-induced infrastructure damage can occur even with minor changes in land motion,' the study's authors write. The study said that the extraction of groundwater is likely the cause of subsidence in Houston, the worst-impacted city. As cities continue to expand, populations increase, and climate change worsens, areas are likely to continue sinking. Droughts, for example, can dry out soil in cities like Houston, leading to further groundwater extraction, continuing the cycle. A separate 2023 study found that New York City is gradually sinking partly because of the weight of its skyscrapers. Meanwhile, Galveston, Texas, is experiencing rapidly rising sea levels, outpacing other coastal cities such as Miami, Florida, and Charleston, South Carolina. New Orleans, Louisiana, is rapidly subsiding at up to 50 millimeters per year. The coastal metropolis is built on soft, marshy land.
