Ecologists point to forests as important sinks for atmospheric carbon. But a new report suggests that climate change could induce environmental stresses that would chnge the role of forests into a net carbon source. The report, titled “Adaptation of Forests and People to Climate Change – A Global Assessment,” was coordinated by the International Union of Forest Research Organizations (IUFRO)…
Members of the House of Representatives have introduced the first federal bill that would attempt to regulate climate change by placing limits on carbon release, ensuring that 25 percent of the nation’s energy comes from renewable sources and reducing the nation’s greenhouse gas emissions by 80 percent by the year 2050. While the Obama administration is weighing whether to use…
To convince naysayers that climate change is real, maybe all we need to tell them is to look up in the sky – or down into the ocean. Two recent studies show that seabirds can be important sentinels of a changing climate. Says Dee Boersma, University of Washington ecologist and one of the world’s penguin experts, in a NY Times…
This just in: Omega-3 fatty acids are healthy not just for you, but may also be good for the environment. We all read about the beneficial effects of omega-3 fatty acids, found most commonly in fish oils in our diets. They buffer against cancer, reduce the risk of cardiac disease and may also improve brain and immune function. But in…
In mid-February, George Will, resident Washington Post conservative and climate-skeptic, wrote an editorial denouncing “Dark Green Doomsayers.” The editorial was filled with anecdotal references of news articles from the 1970’s that declare widespread climate cooling and exclaim that the world will soon find itself in the next ice age. The piece outraged the environmental community and sparked a flurry of…
Researchers said yesterday that the potential rise in global sea level by the year 2100 could be almost double the previous estimates. A rise of this magnitude could affect a tenth of the world’s population. At the International Scientific Congress on Climate Change in Copenhagen, Denmark this week, Konrad Steffen of the University of Colorado at Boulder chaired a session…
Ethanol as the next generation of alternative fuels has stirred significant controversy. While some tout its lower-than-gasoline greenhouse-gas emissions and its usefulness in creating carbon sinks in its agricultural fields, many other ecologists call ethanol production the most inefficient of alternative fuel options. Even the most optimistic scenarios still show that using current technologies, it can take years – in…
With funding from the recent the stimulus bill beginning to trickle down to agencies and budgets for the next two fiscal years on the line, it’s all about the Benjamins these days in Washington. Here are some highlights from today’s issue of the ESA Policy News Update, written by ESA’s Policy Analyst, Piper Corp. 2009 Budget. The fiscal year 2009…
Bioclimatic models attempt to draw correlations between species distributions and climate patterns. As ecologists and climatologists hone these models, they become a useful tool for predicting future species distributions based on projected climate patterns. In the March issue of Ecology, Joshua Lawler of the University of Washington and his colleagues undertook a huge task: using a bioclimatic model, they estimated…
Tree deaths have more than doubled in the western U.S. in the past 20-30 years, and the culprit is climate change, according to a paper published Friday in Science. Warming has all kinds of consequences for species ranges. Changes in temperature can narrow a species’ range or move it latitudinally through changes in average yearly temperatures and alterations of the…
President Barack Obama has been an inspiration to many scientists during his campaign and his transition to office because of his repeated commitments to the sciences and his early appointments of scientists in high-profile cabinet positions and advisory roles. Yesterday he renewed those sentiments in his inauguration speech, vowing to “restore science to its rightful place” in our government. The…
