Those making land use decisions to reduce the harmful effects of climate change have focused almost exclusively on greenhouse gases - analyzing, for example, how much carbon dioxide is released when a forest is cleared to grow crops. A new study in Nature Climate Change aims to present a more complete picture - to incorporate other characteristics of ecosystems that also influence climate.

As a kid growing up near the space program in Huntsville, Ala., reading as much science fiction as he could get his hands on, Kasting had space exploration on his mind all the time. It influenced who he is today as well as the research he's most interested in conducting. By studying early Earth's atmosphere and the origins of oxygen in it, Kasting has become one of the foremost experts on planetary habitable zones. In his book, "How to Find a Habitable Planet," Kasting explains how his research with NASA may be able to detect worlds outside of our solar system that are suitable for sustaining life.

Researchers at the University of British Columbia and Union College (Schenectady, N.Y.) have found that people's death anxiety can influence them to support theories of intelligent design and reject evolutionary theory.

People who look at the past through rose-tinted glasses are happier than those who focus on negative past experiences and regrets, according to a new study published in the journal Personality and Individual Differences. The study helps explain why personality has such a strong influence on a person's happiness. The findings suggest that persons with certain personality traits are happier than others because of the way they think about their past, present and future.

Janet K. Swim, professor of psychology, Penn State, and her colleagues report that growing consumption and growing population are two significant contributors to human impact on the environment. Both substantially increase carbon dioxide levels in the atmosphere, the researchers report in a special issue of American Psychologist that focuses on how psychology contributes to understanding and addressing global climate change. "Engaging in one type of environmentally friendly behavior can predispose one to engage in similar behaviors, inhibit other behaviors, or even increase environmentally harmful behaviors," said Swim.

An international team of scientists has undertaken a study, the results of which have been published in the Proceedings of the National Academy of Sciences, to better understand the link between climate conditions and the disease known as plague. Their results indicate that the amount of rain an area receives over a given time can greatly affect the spread of the disease.

Instinct and the annual increase of daylight hours have long been thought to be the triggers for birds to begin their spring migration. Scientists at the Smithsonian Conservation Biology Institute, however, have found that that may not be the case. Researchers have focused on how warming trends in temperate breeding areas disrupt the sensitive ecology of migratory birds. This new research shows that changes in rainfall on the tropical wintering grounds could be equally disruptive. The team's findings are published in scientific journal Proceedings of the Royal Society B, today, March 30.
