Methane, the main component of natural gas, is the cleanest-burning of all the fossil fuels, but when emitted into the atmosphere it is a much more potent greenhouse gas than carbon dioxide. 

A new study led by researchers at UC San Francisco has found that among older Americans with cognitive impairment, the greater the air pollution in their neighborhood, the higher the likelihood of amyloid plaques – a hallmark of Alzheimer’s disease. 

Under the worst-case scenarios laid out in the United Nations’ climate change projections, global temperatures would increase more than 3.6 degrees Fahrenheit (2 degrees Celsius) by 2100, leading to at least 1.5 feet (0.5 meters) in global sea level rise and an array of disastrous consequences for people and planet. 

As nations went into lockdown to contain the spread of Covid-19, factories halted and cars sat idle, clearing the skies above polluted cities and sending climate-changing emissions to historic lows. 

Three undergraduates created the prototype as part of Aggies Against COVID-19.

A team of scientists has succeeded in visualizing how carbon dioxide (CO2) behaves in an ionic liquid that selectively absorbs CO2. 

The team will identify facilities at risk for flood-induced chemical spills and support efforts to mitigate potential impacts on nearby communities.

The correlation between the high concentration of fine particles and the severity of influenza waves is well known to epidemiologists.
