EPA pulls speakers from conference Scientists explain

water on ancient Mars

3D model explains how water survived frigid Martian climate billions of years ago By JACKSON WELLS SENIOR STAFF WRITER

Though scientists have long observed signs of water on ancient Mars, they could not explain how it came to exist in the frigid climate of those times. But in a paper published in “Icarus,” scientists have recently developed a model of ancient Mars that reconciles this conflict and explains the effects of seasonal temperature variation on the climate. There are a number of examples of evidence that indicate the presence of water on early Mars, such as lakes and valley networks, said Ashley Palumbo GS, co-lead author of the paper. There are also phyllosilicates — clay substances in the Martian surface — that required water to form, said Robin Wordsworth, assistant professor of environmental science and engineering at Harvard and colead author of the paper. Despite this, there had not been a consensus as to how liquid water could have survived in the extremely cold environment.

The Environmental Protection Agency cancelled talks by the keynote speaker and two panelists whose work provides evidence for climate change in Narragansett Bay. Many scientists have denounced the EPA’s decision.

Speakers, whose work provides evidence for climate change in Narragansett Bay, replaced By JON DOUGLAS SENIOR STAFF WRITER

At a conference in Providence Monday, the Environmental Protection Agency cancelled talks by three scientists whose work provides evidence for the harmful effects of climate change on the Narragansett Bay.

Although the EPA helped to fund the report that the conference focused on, the agency initially offered no explanation for why it barred panelists Rose Martin and Emily Shumenchia and keynote speaker Autumn Oczkowski from presenting. The decision left the organizers of the workshop scrambling for new speakers. The cancellation comes under an EPA that has been hesitant to address climate change. EPA chief Scott Pruitt has gone on record saying that he does not believe that human emissions are the primary driver of global

temperature changes, and many environmental researchers have expressed worries that the agency will cut funding to climate research. Additionally, the agency has removed resources for fighting climate change from its website, affecting local governments’ ability to address the issue. Many scientists swiftly denounced the EPA’s decision following coverage from the New York Times and the Washington Post, criticizing the agency online and in a protest in Providence, which was attended by over 40 citizens » See EPA, page 2

The general acceptance among scientists was that the temperature nearly four billion years ago, when the water would have existed, must have been warm enough to cause rainfall and surface runoff, Palumbo said. For their research, Palumbo and Wordsworth, along with Jim Head, professor of geological sciences and co-lead author of the paper, developed a model of Mars to test for the climate where water could exist while remaining within the constraints of known ancient Martian climate knowledge, Wordsworth said. They used the Laboratoire de Météorologie Dynamique global climate model, Palumbo said. Incorporating atmospheric and surface physics, the model was able to accurately recreate climate dynamics and generate a plot of where the valley networks occur. They also used long-term ecological data from Antarctica, which has flowing water despite its frigid terrain. This model offered the team a window into the Mars of 3.8 billion years ago — when life was just forming on Earth — to see water on a completely different planet, Wordsworth said. The team found that average annual temperatures could have been far below the freezing point of water, and liquid water still could have persisted in the warmest hours of » See MARS, page 3

UCS tables vote on proposed Lecturers express concern over job status must take on student activities fee increase Lecturers responsibilities outside of UFB’s proposal would raise student activities fee from $274 to $295, increase UFB budget by $138,000 By EDUARD MUÑOZ-SUÑÉ SENIOR STAFF WRITER

At Wednesday’s general body meeting, the Undergraduate Council of Students tabled voting on a proposal from the Undergraduate Finance Board that recommended that the University Resources Committee raise next year’s student activities fee by $21 per student. UCS will delay the vote until an emergency voting meeting can be held for further discussion. All undergraduates must pay the student activities fee, which goes to UFB for allocation to fund various student clubs. For the current 201718 academic year, the fee was $274 per student, bringing UFB’s budget to $1,731,680, according to UFB’s

proposal. The board recommended the fee increase to $295, raising the group’s budget by $138,000. To determine their funding, student groups are divided into three categories, all of which go through a UCS approval process. Category I groups do not receive baseline funding, while Category II groups receive a $200 baseline funding per semester and Category III groups receive the same funding and can apply for additional supplemental funding from UFB, according to the UCS website. Supplemental funding can range between thousands or even hundreds of thousands of dollars, according to a 2014 UFB release of budget allocations. According to UFB’s constitution, the group can recommend a raise in the student activities fee to UCS, but only UCS can recommend it officially to the URC.

academic purview, such as advising By ROSE SHEEHAN SENIOR REPORTER

In limbo between the temporary, teaching-centric appointments of adjunct and visiting faculty and the research-focused tenure-track faculty, “lecturers at Brown feel that their role here is unique,” said Joel Revill, associate dean of the faculty and adjunct assistant professor of history. Four lecturers expressed concern with their responsibilities, job security and place within the University in interviews with The Herald. Lecturers will “tell you that they’re undervalued, that they’re not treated well; they’re not respected,” said Dean of the Faculty Kevin McLaughlin. “Maybe that’s true at some level … they don’t have the same status in a way.” McLaughlin added that lecturers » See LECTURER, page 2
