Electric Vehicles Contribute Fewer Emissions Than Gasoline-Powered Cars Over Their Lifetimes

Electric Vehicles Contribute Fewer Emissions Than Gasoline-Powered Cars Over Their Lifetimes

Q: Are electric cars really better for the environment than gasoline-powered cars over their lifetimes? 

A: Yes. Electric vehicles typically release fewer greenhouse gas emissions than internal combustion engine vehicles during their life cycles, even after accounting for the increased energy required to make their batteries. And their carbon footprints are expected to get smaller in the near future.

Posts Misrepresent WHO Term ‘Disease X’ for Possible Future Illness

The World Health Organization began using the term “Disease X” in a 2018 planning document to refer to a “currently unknown” illness. But since the term was used at the January meeting of the World Economic Forum, conspiracy theorists baselessly claim Disease X is part of a “Globalist Plan to … Install World Government.”

No Proven Health Risks from Aspartame, But Also No Proven Benefits

No Proven Health Risks from Aspartame, But Also No Proven Benefits

Some research indicates possible negative effects from aspartame, but there’s no definitive evidence linking it to health problems in the general population. Aspartame is safe when consumed within certain limits, according to the U.S. Food and Drug Administration. The daily limit is above the amount people typically ingest.

No Evidence Offshore Wind Development Killing Whales 

Q: Is the development of offshore wind energy farms in the U.S. killing whales?

A: Whales have been dying at an unusual rate along the Atlantic Coast since 2016, often from ship strikes or entanglements with fishing gear. Federal agencies and experts say there is no link to offshore wind activities, although they continue to study the potential risks.

Vaccinated People Not More Susceptible to COVID-19 Than Unvaccinated

Vaccinated People Not More Susceptible to COVID-19 Than Unvaccinated

Q. Are vaccinated and boosted people more susceptible to infection or disease with the omicron variant than unvaccinated people?
A. No. Getting vaccinated increases your protection against COVID-19. Sometimes, certain raw data can suggest otherwise, but that information cannot be used to determine how well a vaccine works.

COVID-19: The Unvaccinated Pose a Risk to the Vaccinated

COVID-19: The Unvaccinated Pose a Risk to the Vaccinated

Q: How do people who have not been vaccinated against COVID-19 pose a risk to people who have been vaccinated?

A: An unvaccinated person who is infected with COVID-19 poses a much greater risk to others who are also unvaccinated. But vaccines are not 100% effective, so there is a chance that an unvaccinated person could infect a vaccinated person — particularly the vulnerable, such as elderly and immunocompromised individuals.

Exploring the Legality of COVID-19 Vaccine Mandates

Exploring the Legality of COVID-19 Vaccine Mandates

Q: Can employers, colleges and universities require COVID-19 vaccinations?

A: Generally, they may require immunizations. But there is some uncertainty about the legality of mandating vaccines authorized for emergency use by the U.S. Food and Drug Administration.

No Evidence Vaccines Impact Fertility

No Evidence Vaccines Impact Fertility

Q: Do the COVID-19 vaccines cause infertility?
A: There’s no evidence that approved vaccines cause fertility loss. Although clinical trials did not study the issue, loss of fertility has not been reported among thousands of trial participants nor confirmed as an adverse event among millions who have been vaccinated. 

What Do the New Coronavirus Variants Mean for the Pandemic?

What Do the New Coronavirus Variants Mean for the Pandemic?

Q: What are the risks of the newly identified coronavirus variants?
A: It’s not yet known whether mutant versions cause more severe disease, but some are likely more contagious. Scientists expect vaccines will work but are monitoring the situation.
