Climate Scientists Weigh-in on Scientific Disagreement and Public Trust

A guest post by Kirk Englehardt, Director of Research Communication, Georgia Institute of Technology

A new report by the Pew Research Center explores many ways scientists engage with the public – and why.

The study is based on a survey of more than 3,700 members of the American Association for the Advancement of Science. It reveals that scientists who study areas that are regularly debated in the media are more likely to engage in public outreach than those working in less controversial areas. They’re also more likely to speak with reporters and blog about their research. Continue reading

Climate Change: “Uncertainty” and the Hottest Year on Record

By Roberta Attanasio, IEAM Blog Editor

Over the last month, much has been said about 2014 being the hottest year on record. The first announcement came from the Japan Meteorological Agency during the first week of January. Later, a joint announcement by NASA and NOAA reinforced the finding: 2014 was the hottest year in more than 120 years of record keeping. The joint announcement underscored the significance of two major scientific branches of the US government reaching the same conclusion through separate data analyses. Continue reading

College Students Demonstrate Gender Bias in Rating Their Professors

By Roberta Attanasio, IEAM Blog Editor

Back in 1999, the Massachusetts Institute of Technology (MIT) acknowledged that female professors suffered from pervasive, albeit unintentional, discrimination. Charles M. Vest, MIT President at the time, said in the Faculty Newsletter: “I have always believed that contemporary gender discrimination within universities is part reality and part perception. True, but I now understand that reality is by far the greater part of the balance.” The statement introduced an accompanying study unveiling the MIT pattern of discrimination — or, under a more current perspective, gender bias.

Jellification: A Sequel to the Disappearance of Water Fleas from Canadian Lakes

By Roberta Attanasio, IEAM Blog Editor

The plenitude of environmental changes currently underway is leading scientists to devise new catchwords for communicating novel, unexpected findings. Think of plastiglomerates, a new type of stone made up of melted plastic and other materials that will likely become part of the rock record. Now, we have “jellification” — very recently conceived to describe the process causing goo balls to wash up on the shores of Canadian lakes. Continue reading

The Environmental and Health Impacts of Fracking: Time to Close the Knowledge Gap?

Hydraulic fracturing, or fracking – the process of extracting natural gas by injecting wells with mixtures of water, sand, and even toxic chemicals at an extremely high pressure – may contaminate drinking water and affect human health, among other unwanted consequences. Continue reading

Neonicotinoid Pesticides: New Findings Highlight Their Role in the Disappearance of Bees

Bees have been declining for years worldwide—this is a well-accepted fact. However, the “why” of this decline is still a matter of debate. Although it is likely that a combination of different factors is contributing to the global bee die-offs, increasing attention is now devoted to the toxic effects of a group of pesticides called neonicotinoids, or neonics for short. They are systemic pesticides—their solubility in water allows them to reach leaves, flowers, roots and stems, even pollen and nectar. One could therefore infer that these pesticides will likely kill not only the insects that farmers want to eliminate, but also pollinators. Continue reading

The Global Decline of Coral Reefs: Is There Hope for Recovery?

During the past few decades, coral reefs—the rainforests of the sea—have been declining at an alarming rate around the world. The threats faced by these extremely diverse and fragile ecosystems are numerous and difficult to control. In addition to weather-related damage, pollution, ocean acidification, coral mining, disease, overfishing and destructive fishing practices, coral reefs are subjected to the negative effects of global warming—increasing sea surface temperatures lead to coral bleaching, a process that makes corals become bone white and often die. A couple of years ago, David Gruber wrote in the New York Times, “It is difficult being a coral reef scientist in 2012. The system we are studying is dwindling—and we feel there is an urgent need to understand the ecosystem while it still has a pulse. Coral reefs are on target to be one of the first major ecosystems to be pushed to an unproductive state.” Continue reading
