Skeptical Science: Claiming that Listerine alleviates cold symptoms is false: To repeat or not to repeat the myth during debunking?

With terms such as “post-truth” and “fake news” becoming increasingly prominent in the media and public discourse, the ability to effectively correct inaccurate information has never been more pertinent. Unfortunately, the task of correcting misinformation is far from trivial. In many instances, issuing corrections remains only partially effective and people often continue to rely on outdated…

Skeptical Science: To lead on climate, leave the ivy tower

America’s top universities expend considerable efforts to lead in the rankings, but last week they fell short—missing a critical opportunity to show moral leadership on climate change. If top schools want to lead on climate action, they should join the “We Are Still In” coalition, a collection of states, cities, businesses, and universities promising to support the Paris Climate Agreement.

Skeptical Science: New research may resolve a climate ‘conundrum’ across the history of human civilization

Earth’s last ice age ended about 12,000 years ago. The warmer and more stable climate the followed allowed for the development of agriculture and the rise of human civilization. This important period encompassing the past 12,000 years is referred to as the Holocene geological epoch. It also created a “conundrum” for climate scientists, because global temperatures simulated by climate models…

Skeptical Science: The Trump Effect - Making Lemonade from Lemons

It may just be me but I get the distinct impression that - "thanks" to Donald Trump's ill-advised and shortsighted decision to withdraw the U.S. from the Paris agreement - people have been hearing a lot more about climate change since June 1.

As one datapoint, the topic got a lot of coverage on German TV on June 2 with for example about 8 out of 15 minutes dedicated to it in the main news at…

Skeptical Science: The Larsen C ice shelf collapse hammers home the reality of climate change

Very soon, a large portion of an ice shelf in Antarctica will break off and collapse into the ocean. The name of the ice shelf is Larsen C; it is a major extension from of the West Antarctic ice sheet, and its health has implications for other ice in the region, and sea levels globally.

How do we know a portion is going to collapse? Well, scientists have been watching a major rift (crack) that…

The science of climate change is clear. Scientists know that the Earth is warming and that humans are the reason. We also know that the Earth will continue to warm in the future; however, we can do something about it. We can dramatically change the trajectory.

If the science is so clear, why are there still so many people that don’t accept it? Why are there so many people who try to deny the…

There are some other less obvious threats, and many of the threats vary by…

Skeptical Science: Study: inspiring action on climate change is more complex than you might think

We know humans are causing climate change. That is a fact that has been known for well over 100 years. We also know that there will be significant social and economic costs from the effects. In fact, the effects are already appearing in the form of more extreme weather, rising sea levels, ocean acidification, and so on.

So why haven’t humans done much about the problem? Answering that question…
