Climate Change Could Supercharge Threat of Antibiotic Resistance: Study

By Andrea Germano

The World Health Organization and U.S. Centers for Disease Control and Prevention have previously sounded alarms about the growing issue of antibiotic resistance—a problem already linked to overprescribing of antibiotics and industrial farming practices. Now, new research shows a link between warmer temperatures and antibiotic resistance, suggesting it could be a greater threat than previously thought on our ever-warming planet.


The study, led by epidemiologists from Harvard Medical School (HMS), Boston Children's Hospital, and the University of Toronto, was published this week in the journal Nature Climate Change.

"The effects of climate are increasingly being recognized in a variety of infectious diseases, but so far as we know this is the first time it has been implicated in the distribution of antibiotic resistance over geographies," said Derek MacFadden, an infectious disease specialist and research fellow at Boston Children's and study co-author.

"We also found a signal that the associations between antibiotic resistance and temperature could be increasing over time," he said.

For the study, the researchers zeroed in on three of most commonly reported resistant bacteria—E. coli, K. pneumoniae and S. aureus (staph)—using data from hundreds of facilities across 41 states.

They found that local average minimum temperature increases of 10 degrees were associated with a 4.2 percent increase in antibiotic-resistant strains of E. coli. That temperature change was also associated with a 2.2 percent increase in antibiotic-resistant K. pneumoniae, and a 3.6 percent increase in S. aureus.

There was also a link with another issue facing the planet—population growth. The team found an increase of 10,000 people per square mile was associated with a 3 percent increase in antibiotic resistance in E. coli and 6 percent for K. pneumoniae.

"The bottom line," said co-author John Brownstein, chief innovation officer and director of the Computational Epidemiology Group at Boston Children's and professor of pediatrics at HMS, "is that our findings highlight a dire need to invest more research efforts into improving our understanding of the interconnectedness of infectious disease, medicine, and our changing environment."

In the U.S. alone, according to the CDC, 2 million people annually become infected with antibiotic-resistant bacteria, and at least 23,000 people die each year as a direct result of those infections.

A fact sheet from WHO, meanwhile, declares antibiotic resistance "one of the biggest threats to global health, food security, and development today."

Florida Manatee: 10% of Population Could Be Wiped Out This Year

2018 has not been a good year for Florida's iconic manatees. A total of 540 sea cows have died in the last eight months, surpassing last year's total of 538 deaths, according to figures posted Monday by Public Employees for Environmental Responsibility (PEER).

The figure will likely climb higher before the year's end amid the state's ongoing toxic algae crisis. The red tide in the state's southwest is the known or suspected cause of death for 97 manatees as of Aug. 12, the Florida Fish & Wildlife Conservation Commission recently reported.

Walmart Joins Ranks of Retailers Pulling Toxic Paint Strippers From Shelves – When Will EPA Follow Suit?

By Sarah Vogel

Monday, Walmart announced that it will stop selling paint strippers containing methylene chloride or N-methylpyrrolidone (NMP) in stores by February 2019—making it the first general merchandise retailer to take such action. Walmart's announcement follows the strong leadership demonstrated by Lowes, Home Depot and Sherwin Williams, all of which have committed not to sell methylene chloride- and NMP-based paint stripping products by the end of the year. Importantly, Walmart's action goes beyond its U.S. stores, including those in Mexico, Canada and Central America, as well as their online store.

New England Seal Die-Off Could be Linked to Chemical Pollution

Researchers think a mysterious die-off of seals along the Maine coast could be linked to chemical pollution, the Portland Press Herald reported Sunday.

More than 400 dead or stranded seals have washed up on the Maine coast so far this year, more than in any of the past seven years, according to National Oceanic and Atmospheric Administration (NOAA) statistics.

Greek Island to Be First in Mediterranean to Power Itself With Only Wind and Solar

The Greek island of Tilos is set to be the first in the Mediterranean to power itself entirely with wind and solar power, The Associated Press reported Sunday.

The final tests of a new system that will allow the island to power itself with batteries recharged by a solar park and 800-kilowatt wind turbine are taking place this summer, and the system is expected to go live later this year.

Please Stop Flushing Your Contact Lenses

Contact lenses may appear harmlessly soft and small, but a big chunk of American users are improperly disposing their used lenses and adding to the planet's microplastic problem, Arizona State University researchers found.

In a survey of 409 wearers, about 1 in 5 responded that they flushed their used lenses down the toilet or sink instead of throwing them in the trash, according to a new study presented at the American Chemical Society's National Meeting and Exposition.

'We Are Climbing Rapidly Out of Humankind's Safe Zone': New Report Warns Dire Climate Warnings Not Dire Enough

By Jon Queally

Offering a stark warning to the world, a new report out Monday argues that the reticence of the world's scientific community—trapped in otherwise healthy habits of caution and due diligence—to downplay the potentially irreversible and cataclysmic impacts of climate change is itself a threat that should no longer be tolerated if humanity is to be motivated to make the rapid and far-reaching transition away from fossil fuels and other emissions-generating industries.

Trump Power Plant Plan Will Significantly Increase CO2 Pollution

The Trump administration is expected on Tuesday to propose a major rollback of the Clean Power Plan, President Obama's signature climate policy.

The replacement will relax rules for coal-fired plants and will very likely increase air pollution and planet-warming carbon dioxide emissions.
