Here are some articles from science periodicals for your DNR weekend reading:

Science Daily: Cold Winters Caused by Warmer Summers, Research Suggests
A group of scientists offers up a convincing explanation for the harsh winters recently experienced in the Northern hemisphere: increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes.

Science DailySolutions for a Nitrogen-Soaked World
Nitrogen is  an essential nutrient but also a pollutant — both a byproduct of fossil fuel combustion and a fertilizer that feeds billions. Agriculture, industry and transportation have spread nitrogen liberally around the planet, say scientists, who argue for a systematic approach to managing the resource and its consequences.

Scientific American: Current Developments: Innovative Ideas on How to Make Electric Cars Cost-Efficient Take Shape
Expensive batteries and limited recharging stations are the big impediments to making electric-powered vehicles cost-competitive with non-hybrid internal combustion vehicles. New electricity pricing and distribution models may be needed to break the logjam.

environment360: China’s Reforestation Programs: Big Success or Just an Illusion?
China has undertaken ambitious reforestation initiatives that have increased its forest cover dramatically in the last decade. But scientists are now raising questions about just how effective these grand projects — many of them with non-native trees and little species diversity — will turn out to be.

Attention Readers:  Rain falling on last week’s heavy snowfall in Western Washington will raise the risks of landslides. Please report any landslides you see — first to 911 if there are injuries or property damage and then to DNR (even the small ones) for our database. Thanks to all who have contributed already. Here’s how to report a landslide to DNR.
