Small volcanic eruptions could be slowing global warming—new ground-, air- and satellite measurements show that small volcanic eruptions that occurred between 2000 and 2013 have deflected almost double the amount of solar radiation previously estimated. By knocking incoming solar energy back out into space, sulfuric acid particles from these recent eruptions could be responsible for decreasing global temperatures.



Sacred Gum Tree Leaves Threaten Future of Australian Pro Tour Tennis in Alice Springs—A 2014 Tennis Australia report expressed concern about the number of leaves that fell on the court during the 2014 event, but organizers cannot trim or cut down the trees without approval from native title holders and the council, according to the tennis club’s tournament director Matt Roberts.


Parks Canada Using Old Christmas Trees to Protect Sand Dunes—piles of old Christmas trees are stacked up along Brackley Beach of Prince Edward Island to fill in what are known as blow out areas where sand has drifted away.

How the Gulf Coast Can Save the Monarchs—a dramatic decline in monarchs has been linked to the loss of milkweeds, one of the most important monarch food sources in Eastern North America.
Longleaf pines of Gulf Coast may well determine whether the monarch and its great annual migration survives. More than 90 percent of all milkweed and climbing milkweed species found in eastern North America occur within the larger longleaf pine ecosystem and 15 or so of those species are found nowhere else but in longleaf forests.
