The Eco News Roundup brings stories and commentary about issues related to climate change, renewable energy and the environment.
Across the United States and the world, climate change is already affecting communities, livelihoods, and the environment. In response, many parts of the federal government are taking action to help Americans adapt to current and potential risks. Some of these actions are described below.
WASHINGTON (March 1, 2013) – The U.S. State Department today released a draft Supplemental Environmental Impact Statement for the Keystone XL tar sands pipeline proposed to pass through the United States from Canada to the Gulf of Mexico. Natural Resources Defense Council experts have begun analyzing the draft review and have found numerous major flaws,
WASHINGTON (March 1, 2013) – The D.C. Circuit Court of Appeals today upheld a 2008 decision to protect polar bears throughout their range as a “threatened” species under the U.S. Endangered Species Act. The court dismissed challenges by the state of Alaska, polar bear trophy hunters and others seeking to strip the polar bear of its protection.
Lawrence Livermore Lab News Release
A clear change in salinity has been detected in the world’s oceans, signaling shifts and acceleration in the global rainfall and evaporation cycle tied directly to climate change.
A newly released international study reveals that the issue of climate change is not a priority for people in the United States and around the world. The surveys showed that when asked to rank priority worries, people were five times more likely to point to the economy over the environment. Additionally, when asked about climate change, people identified the issue as more as a national problem than a personal concern.
In a study published February 24 in Nature Climate Change researchers used the latest emissions scenarios and climate models to show how varying levels of carbon emissions are likely to result in more frequent and severe coral bleaching events.
A continental-scale chemical survey in the waters of the eastern U.S. and Gulf of Mexico is helping researchers determine how distinct bodies of water will resist changes in acidity. The study, which measures varying levels of carbon dioxide (CO2) and other forms of carbon in the ocean, was conducted by scientists from 11 institutions across the U.S. and was published in the journal Limnology and Oceanography.
A group of international ecological scientists led by the University of Adelaide have rejected a doomsday-like scenario of sudden, irreversible change to Earth’s ecology. In a paper published February 28 in the journal Trends in Ecology and Evolution, the scientists from Australia, US and UK argue that global-scale ecological tipping points are unlikely and that ecological change over large areas seem to follow a more gradual, smooth pattern.
While short-term weather is notoriously volatile, climate is thought to represent a kind of average weather pattern over a long period of time. This dichotomy provides the analytical framework for scientific thinking about atmospheric variability, including climate change. But the weather-climate dichotomy paints an incomplete picture — one that may be complicating efforts to untangle natural variations in climate from human-made effects, according to McGill University physics professor Shaun Lovejoy. In a paper published recently in the journal Eos, Transactions, American Geophysical Union, and in a forthcoming book, Lovejoy argues that statistical analysis shows there is a period between short-term weather and long-term climate that should be recognized as distinct.
Particles from the upper atmosphere trapped in a deep pile of Antarctic snow hold clear chemical traces of global meteorological events, a team from the University of California, San Diego and a colleague from France have found. Anomalies in oxygen found in sulfate particles coincide with several episodes of the world-wide disruption of weather known as El Niño and can be distinguished from similar signals left by the eruption of huge volcanoes, the team reports in the early online edition of the Proceedings of the National Academy of Sciences published the week of February 25.
When Jim Thomas and his global team of researchers returned to the Madang Lagoon in Papua New Guinea, they discovered a treasure trove of new species unknown to science. This is especially relevant as the research team consisted of scientists who had conducted a previous survey in the 1990s.
At BPI Campus our Progressive Agenda is:
1. People matter more than profits.
2. The earth is our home, not our trash can.
3. We need good government for both #1 and #2.
