Effects of a Warming Planet on Tropical Lizards May Not be Significant
May 18, 2013 07:50 AM - Dartmouth University via ScienceDaily
A new Dartmouth College study finds human-caused climate change may have little impact on many species of tropical lizards, contradicting a host of recent studies that predict their widespread extinction in a rapidly warming planet. Most predictions that tropical cold-blooded animals, especially forest lizards, will be hard hit by climate change are based on global-scale measurements of environmental temperatures, which miss much of the fine-scale variation in temperature that individual animals experience on the ground, said the article's lead author, Michael Logan, a Ph.D. student in ecology and evolutionary biology.
DiCaprio's Environmental Charity Art Auction Raise $33 Million
May 17, 2013 07:37 AM - Editor, Justmeans
Leonardo DiCaprio's environmental charity auction at Christie's in New York has raised an impressive $33.3 million from wealthy art collectors. Most of the sale proceeds went to environmental protection causes promoted by the Leonardo DiCaprio Foundation. The Hollywood actor, who was himself present at the auction, urged collectors to bid as if the planet's fate "depends on us" - and they responded to his call generously.
EarthTalk: Climate Change and Hawaii’s Coral Reefs
May 16, 2013 09:04 AM - EarthTalk, Global Warming is Real
Despite sweeping protections put in place near the end of George W. Bush's presidency for large swaths of marine ecosystems around the Hawaiian Islands, things are not looking good for Hawaii’s coral reefs. Poisonous run-off, rising ocean levels, increasingly acidic waters and overfishing are taking their toll on the reefs and the marine life they support. Biologists are trying to remain optimistic that there is still time to turn things around, but new threats to Hawaii's corals are only aggravating the situation...
Study Shows Scientists Agree on Anthropogenic Climate Change
May 16, 2013 06:02 AM - ScienceDaily
A comprehensive analysis of peer-reviewed articles on the topic of global warming and climate change has revealed an overwhelming consensus among scientists that recent warming is human-caused. The study is the most comprehensive yet and identified 4000 summaries, otherwise known as abstracts, from papers published in the past 21 years that stated a position on the cause of recent global warming -- 97 per cent of these endorsed the consensus that we are seeing human-made, or anthropogenic, global warming (AGW) Led by John Cook at the University of Queensland, the study has been published 16 May, in IOP Publishing's journal Environmental Research Letters.
Mussels May Help Filter Polluted Waters
May 14, 2013 10:28 AM - Editor, ENN via YaleEnvironment360
Scientists from the U.S. National Oceanic and Atmospheric Administration (NOAA) set up an experimental raft at the mouth of New York City's Bronx River last spring. Hanging beneath it were long, sock-like tendrils that had been seeded with Geukensia demissa, commonly known as ribbed mussels. The point of the two-year experiment was to see whether mussels would survive or even thrive given the industrial and organic effluent that flows from the Bronx into the greater New York Harbor. If the mussels did in fact prosper in this environment, it could have implications for how we might help clean up coastal waters in various parts of the world.
Nature is Good for your Health!
May 14, 2013 06:31 AM - Richard J Dolesh, The Ecologist
A walk in the park can calm and restore you. This is something we take for granted in parks and recreation, because we have known it to be true ever since we started spending time in nature. But new research reported in the British Journal of Sports Medicine now provides scientific proof that walking in nature and spending time under leafy shade trees causes electrochemical changes in the brain that can lead people to enter a highly beneficial state of "effortless attention." The UK researchers state with some justifiable academic stuffiness that "..happiness, or the presence of positive emotional mindsets, broadens an individual's thought-action repertoire with positive benefits to physical and intellectual activities, and to social and psychological resources."

Happy Mother's Day
May 12, 2013 06:44 AM - Ari Pineda, Program Assistant, Wildscreen USA , ARKive.org
Today is Mother's Day in the US and is a chance to honor and give thanks to mothers, both human and those of the animal variety! In nature, mothers come in all shapes and sizes and are equipped with a wide range of different parenting styles. We've selected a handful of moms with unique and fascinating methods for raising their babies from keeping little ones close for years to kicking them right out of the nest before they can even fly! Furry and ginormous, American bison mothers live with their young in hierarchical herds led by one dominant female. Within three hours of being born, the newborn calves are able to run about but are guarded closely by many of the herds' mothers who will charge any intruders. Talk about safety in numbers!
CO2 Levels Top 400 ppm at Hawaii Monitoring Station
May 11, 2013 07:38 AM - Roger Greenway, ENN
CO2 levels have been increasing relatively steadily for more than 50 years. On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958. Independent measurements made by both NOAA and the Scripps Institution of Oceanography have been approaching this level during the past week. It marks an important milestone because Mauna Loa, as the oldest continuous carbon dioxide (CO2) measurement station in the world, is the primary global benchmark site for monitoring the increase of this potent heat-trapping gas. Carbon dioxide pumped into the atmosphere by fossil fuel burning and other human activities is the most significant greenhouse gas (GHG) contributing to climate change. Its concentration has increased every year since scientists started making measurements on the slopes of the Mauna Loa volcano. The rate of increase has accelerated since the measurements started, from about 0.7 ppm per year in the late 1950s to 2.1 ppm per year during the last 10 years.
Light-Scattering Properties are Risk Factor for Coral Reef Survival
May 9, 2013 12:58 PM - Allison Winter, ENN
Coral reefs have been gaining a lot of attention by conservation groups as environmental and human stresses are causing irreparable damage to these reefs. Stresses such as warming oceans and climate change are going to serve as future obstacles for these coral populations. However, the study of dying corals is complex, and researchers have found that some corals die while others do not, even when exposed to the same environmental conditions. In order to figure out this conundrum, a research team from Northwestern University and The Field Museum of Natural History found that corals themselves play a role in their susceptibility to deadly coral bleaching due to the light-scattering properties of their skeletons.
