New modeling shows where global warming will increase cyanobacteria
Scientists say it’s all but certain that global warming will increase potentially threatening outbreaks of freshwater algae that can produce toxins dangerous to people and animals.
A team lead by Tufts University researcher Steven C. Chapra has developed a modeling framework showing harmful algal blooms will increase the most in the northeastern region of the U.S. but that the biggest economic impact will be felt in the Southeast, where waters important for recreation will probably take a big hit.
Exposure to systemic neonicotinoid pesticides causes queen bumblebees to lay 26 percent fewer eggs. That rate of decline could result in the extinction of some wild bumblebee populations, according to researchers at the University of Guelph.
Measure would exempt huge logging projects from environmental review
Logging projects as large as 10,000 acres could be rushed to approval without environmental reviews under a new bill proposed by Sen. John Thune, (R-S.D.).
As introduced, the law would limit public comment and disclosure of the environmental impacts of large-scale logging projects. The measure is similar to a House bill that also aims to significantly limit public input and scientific environmental review under the National Environmental Policy Act.

It’s highly unlikely Earth would have seen a three-year run of record global temperatures without its blanket of human-caused greenhouse gases, scientists concluded in a new study that tried to pin down the relationship between record warmth and human-caused global warming.
Without the warming effect of carbon dioxide, methane and other heat-trapping pollutants, there’s only a 0.03 percent chance that there would be three consecutive years of record temperatures; when the warming effects of greenhouse gases are added into the equatio, the odds of three consecutive record-breaking years happening any time since 2000 rises to as high as 50 percent, according to the new study.

Salzburg and Tirol may get all the glory for dramatic mountain scenery, singing nuns and happy cows, but the northeastern quadrant of Austria also has its charms. The Waldviertel is one of the most rural and agricultural sections of the country, with a pleasing patchwork of carefully tended fields and forests, not to mention ponds and lakes that have been managed for aquaculture for several hundred years. The images in this set were all taken around the town of Zwettl, the heart of the Waldviertel at the confluence of the Kamp and Zwettl rivers.

Canada is on track for a near-record wildfire season this year. So far, there have been more than 500 fires just in British Columbia, burning across more than 1 million acres. Firefighting costs have already reached more than $172 million, and weeks of warm and dry weather will keep the fire danger high.
