The confidential National Air Quality Site Assessment Tool helps the livestock owner/operator figure out how changing on-site practices can reduce emissions of ammonia, methane, volatile organic compounds, hydrogen sulfide, fine particulates, and odors. This may be useful for journalists; whether an owner/operator will discuss the details of their operation or not, there's a story.

SEJ regrets to announce that biweekly publication of the TipSheet will be suspended after the next issue pending renewal of adequate funding.There is some chance the TipSheet may be reinvented. In order for this to happen, it will help if you let us know what you did and didn't like about the TipSheet.

This year's meeting of the American Association for the Advancement of Science, Feb 16-20 in Vancouver, BC, offers dozens of sessions on environmental topics — climate change, mineral resource dependency, water, critique of science journalism, disaster recovery, science integrity in government agencies, and more.

NOAA, the USFWS, and the NY State Dept. of Environmental Conservation (representing all state and wildlife agencies) released on Jan. 19, 2012, a draft of the first national strategy for responding to climate change effects on plants, fish and wildlife. The public comment period is open until March 5, 2012, and public meetings and a webinar will occur until Feb. 22, 2012.

Finally, after numerous delays amid allegations of political interference by people who don't want to see documented evidence of climate shifts, the wait is over. The new detailed interactive map is based on data from 1976-2005, and is the first official revision since the 1990 update.

The American Horticultural Society and the National Arbor Day Foundation offer generalized hardiness maps as a starting point, until the US Department of Agriculture gets around to unveiling its own update.

One day, EPA may propose rules for regulating greenhouse gas emissions from power plants and petroleum refineries. But the process continues to drag out, with the consent of the state and local governments and environmental advocacy groups that have been litigating for about five years to make the agency take action.

From the latest issue of SEJ's biweekly TipSheet: EOL, which is searchable by both common and scientific terms, has vastly expanded its content since its launch in 2008 and now provides extensive nitty-gritty on about half of all described species, as laid out in more than 950,000 pages and more than 760,000 images.

Snow cover has many implications, from ski resorts short on snow and farmers who rely on snowmelt for irrigation to firefighters and residents battling major fires in unusual locations in the middle of winter and smothering blizzards in areas at the other end of the extreme snow spectrum this year.

The analysis can be a useful starting point for targeting angles you want to investigate for toxic pollution stories. The raw data also offer numerous ways to look at occurrences and trends in many ways nationally and locally the agency hasn't addressed or emphasized in its analysis.
