Study: More than 68% of the Western U.S. Affected in One Day by Air Pollution from Wildfires

Large wildfires and severe heat events are happening more often at the same time, worsening air pollution across the western United States, a study led by Washington State University researchers has found. In 2020, more than 68% of the western U.S. – representing about 43 million people – were affected in one day by the resulting harmful-levels of air pollution, the highest number in 20 years.

Study Uncovers the Different Effects of Ocean Acidification on Phytoplankton's Energy Stores

Ocean acidification-;which is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean-;is a significant threat to the structure and function of marine life. In a study published in the New Phytologist, investigators have uncovered the different effects that ocean acidification has on the energy stores of phytoplankton (single-celled plants that are critical to the aquatic food chain) called diatoms.

Cold Weather Kills a Lot More People than Heat in India

A study of the correlation between temperature and mortality in the Indian city of Pune has found that cold, rather than heat, is by far the bigger killer. This is at odds with warnings and mitigating measures authorities have been taking in anticipation of climate change.

Power Costs and Reliability Remain Vulnerable to Extreme Weather on the West Coast of U.S.

Two new studies led by a North Carolina State University researcher offer a preview of what electricity consumers on the West Coast could experience under two different future scenarios: one where excessive heat due to climate change strains power supplies, and one where the grid shifts toward renewable energy while the climate follows historic trends. In both cases, they found power costs and reliability remain vulnerable to extreme weather.

New System Utilizes Renewable Electricity to Directly Convert Carbon Dioxide into Pure Formic Acid

Anthropogenic emissions of carbon dioxide bring a series of climatic and environmental problems including global warming. Artificially upcycling of carbon dioxide into value-added fuels and chemicals, powered by "green electricity" of renewable energy, provides an elegant route to close the anthropogenic carbon cycle.
