Studies find microplastics in human lungs, blood stream; scientists investigating possible health risks
Scientists from the Netherlands and the U.K. recently identified microplastics deep in the lungs of some surgical patients and in the blood of anonymous donors. Researchers say that it's possible to take in these particles through the air we breathe. Leigh Shemitz, president of SoundWaters, and Paul Anastas, director of the Center for Green Chemistry at Yale University, join CBS News' Lana Zak to discuss microplastics' impact on humans and what can be done to mitigate plastic pollution. - CBS News
By 2100, we could be heading towards a loss of life in our oceans that rivals some of the largest extinction events in Earth's history if we don't continue to tackle the climate catastrophe, new modeling warns. But "it is not too late to enact the reductions in greenhouse gas emissions needed to avoid a major extinction event," Princeton geoscientists Justin Penn and Curtis Deutsch explain in their paper. Using modeling calibrated against ancient fossil records, they predict the consequences of runaway climate change on marine animals and provide a plausible explanation for an enduring ocean mystery in the process. - Science Alert
If the United States switched completely to cleaner energy vehicles and power plants, it would not only benefit the environment but also save an estimated 110,000 lives and $1.2 trillion in health costs over the next 30 years, the American Lung Association says in a new report. “These numbers are enormous," said Will Barrett, the national senior director of advocacy, clean air, for the American Lung Association. "It's hard to wrap your head around. $1.2 trillion in public health benefits and 100,000 lives saved." - ABC News
AZ regulators deny SRP gas plant expansion, citing community impacts and insufficient supporting evidence
The Arizona Corporation Commission on Tuesday voted 4-1 to deny an 820-MW expansion at a gas plant proposed by Salt River Project. Regulators said there was insufficient evidence in the record to make a decision, and the expansion would put too much pressure on the nearby, historically-Black community of Randolph. - Utility Dive
Note: This different GeoNews seems worth including. Dr. Hayhoe has been a featured speaker at AGU, the yearly conference of ~25,000 geoscientists in San Francisco.
Climate Scientist Dr. Hayhoe talks about living in Texas, how the issue of climate change became Republican vs Democrat, which groups of Americans we need to target to make change, fossil fuel companies paying to spread disinformation, how to communicate with someone who doesn’t believe in climate change, and her new book "Saving Us: A Climate Scientist’s Case for Hope and Healing In A Divided World." - YouTube
