The potential impact of your online footprint on your career and job search

Dear Sam: My daughter graduated from college, started her first job, and was recently fired from her role as she made some disparaging remarks about her employer on her Facebook page. Needless to say, she is embarrassed and concerned about the impact this will have on her employment search. She needs to make her Facebook page completely private — or delete it entirely, in my opinion — but beyond that, what should she do to curtail any additional fallout from her actions? — Catherine

Dear Catherine: What a shame, Catherine, an opportunity vanished in the stroke of a few keys. This is not the first time I have heard of this happening as candidates are just really learning that what they do “privately” can affect them “professionally.” First, as you know, but to reinforce for readers, everything on Facebook is the property of Facebook, so know, even if you have a private profile, your information is being viewed by those other than your “friends.” Likewise, if you post information and are not careful about your privacy settings, you could have a friend share the post, which could take the content entirely out of your control. If you are going to have a Facebook page, you must make it as private as possible unless you are never going to post anything on there that could damage your personal or professional character.

There are even companies asking candidates to log in to their Facebook accounts during interviews. I’m not joking. In fact, this is common enough that it even has a name — Shoulder Surfing! Providing anyone with access to your Facebook account, or giving anyone your password, is absolutely against Facebook policy. You should never allow an employer to see you log in to your account. If it is private, it is exactly that, private. Candidates should feel confident in refusing such a request and citing either the Facebook user policy or explaining that they themselves have a social media policy that defines never providing anyone with access to any of their social media accounts, nor would they ever defy a future employer’s social media policy.

As for your daughter, when she is asked why she left her past employer, she will indeed have to be honest. Being terminated and the reasons for such activity will be found out during a background check, so she has nothing to gain by not being completely honest. Besides, this is an excellent opportunity to demonstrate how she learned a lesson, overcame an obstacle, and moves forward. Employers know that employees will face challenges in the ordinary course of their roles, and they want resilient team members who are not easily derailed.

During her interviews, your daughter will want to tell the truth and immediately present what she learned from the experience. Explaining to a future employer the steps she has taken to ensure this will never happen again — making her Facebook page private and also maturing to the point that sharing a thought

Unprecedented energy use since 1950 has transformed humanity’s geologic footprint

A new study coordinated by CU Boulder makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as the Anthropocene. Distinct physical, chemical and biological changes to Earth’s rock layers began around the year 1950, the research found.

Led by Jaia Syvitski, CU Boulder professor emerita and former director of the Institute of Alpine Arctic Research (INSTAAR), the paper, published today in Nature Communications Earth and Environment, documents the natural drivers of environmental change throughout the past 11,700 years—known as the Holocene Epoch—and the dramatic human-caused shifts since 1950. Such planetary-wide changes have altered oceans, rivers, lakes, coastlines, vegetation, soils, chemistry and climate.

“This is the first time that scientists have documented humanity’s geological footprint on such a comprehensive scale in a single publication,” said Syvitski, former executive director of the Community Surface Dynamics Modeling System, a diverse community of international experts from who study the interactions between the Earth’s surface, water and atmosphere.

In the past 70 years, humans have exceeded the energy consumption of the entire preceding 11,700 years—largely through combustion of fossil fuels. This huge increase in energy consumption has then allowed for a dramatic increase in human population, industrial activity, pollution, environmental degradation and climate change.

The study is the result of work by the Anthropocene Working Group (AWG), an interdisciplinary group of scientists analyzing the case for making the Anthropocene a new epoch within the official Geological Time Scale, characterized by the overwhelming human impact on the Earth.

The word Anthropocene follows the naming convention for assigning geologically defined lengths of time and has come to embody the present time during which humans are dominating planetary-scale Earth systems.

In geological time, an epoch is longer than an Age but shorter than a Period, measured in tens of millions of years. Within the Holocene epoch, there are several Ages—but the Anthropocene is proposed as a separate Epoch within Earth’s planetary history.

“It takes a lot to change the Earth’s system,” said Syvitski. “Even if we were to get into a greener world where we were not burning fossil fuels, the main culprit of greenhouse gases, we would still have a record of an enormous change on our planet.”

Unambiguous markers of the Anthropocene

The 18 authors of the study compiled existing research to highlight 16 major planetary impacts caused by increased energy consumption and other human activities, spiking in significance around or since 1950.

Between 1952 and 1980, humans set off more than 500 thermonuclear explosions above ground as part of global nuclear weapons testing, which have forever left a clear signature of human-caused radionuclides—atoms with excess nuclear energy—on or near the surface of the entire planet.

Since about 1950, humans have also doubled the amount of fixed nitrogen on the planet through industrial production for agriculture, created a hole in the ozone layer through the industrial scale release of chlorofluorocarbons (CFCs), released
