Climate impacts on health and urban areas: Heatwaves and death rate

Over the last half-century, the probability of heat extreme events has changed by orders of magnitude in almost every region of the world, with occurrences that are now up to a hundred times more in respect to a century ago. Of all-natural disasters, extreme high temperature events are the main cause of weather-related mortality and […]

Researchers propose a framework for evaluating the impacts of climate change on California’s water and energy systems

Hydroelectric stations like Shasta Dam, along the Sacramento River, are integral to California’s water and energy needs. Credit: U.S. Bureau Of Reclamation As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand will intensify. But water and energy are inextricably linked. For instance, nearly a fifth of California’s energy […]

Researcher uses machine learning to demonstrate that DNA impacts cancer risk

Lifestyle, or put another way ‘bad habits’, is one of the textbook explanations for why some people are at higher risk for cancer. We often hear that smoking increases our risk of developing lung cancer or that a high-fat diet increases our risk of developing bowel cancer, but not all smokers get lung cancer and […]

Dust from Receding Glaciers May Have Major Atmospheric Impacts

In spring 2016 in the remote northern reaches of Yukon, Canada, a glacier melted so quickly that its meltwater cut a new path through the ice and changed the course of the Ä’äy Chù, or Slims River. When the old riverbed dried out, the basin’s fine-grained dirt (created by glaciers grinding against bedrock) […]

Stratospheric Weather Impacts Light Species at Great Heights

Using three simulation models (NAVGEM, TIE-GCM and TIME-GCM) and measurements obtained from the TIMED/SABER instrument, Jones et al. [2020] examine the effects of sudden stratospheric warmings (SSWs) on minor constituents in the upper mesosphere and thermosphere. High latitude, wintertime enhanced planetary wave activity in the troposphere and stratosphere changes the circulation and local […]

Researchers find that timing of mass extinctions lines up with asteroid impacts and massive volcanic eruptions — ScienceDaily

Mass extinctions of land-dwelling animals — including amphibians, reptiles, mammals, and birds — follow a cycle of about 27 million years, coinciding with previously reported mass extinctions of ocean life, according to a new analysis published in the journal Historical Biology. The study also finds that these mass extinctions align with major asteroid impacts and […]

Pandemic has surprising impacts on public transit demand

Credit: Pixabay/CC0 Public Domain The COVID-19 pandemic had surprising effects on demand for public transit in American cities, new research suggests. While demand for public transit dropped about 73% across the country after the pandemic hit, the reduction didn’t impact all cities equally, according to the study, which analyzed activity data from a widely used […]

Comparing Impacts of CO2 and Particle Emission Reductions

Black carbon contained in airborne particles is often cited as a major factor warming the climate. Kumar et al. [2020] evaluate the temperature and climate forcing changes associated with modified airborne particulate matter concentrations driven by reductions in California greenhouse gas emissions. Although the adoption of low-carbon energy sources improved surface-level air quality […]
