(46) Physical changes—including rising air and seawater temperatures and decreasing seasonal ice cover—appear to be the cause of a series of biological changes in the northern Bering Sea ecosystem that could have long-range and irreversible effects on the animals that live there and on the people who depend on them for their livelihoods. In a paper published March 10 in the journal Science, a team of U.S. and Canadian researchers use data from long-term observations of physical properties and biological communities to conclude that previously documented physical changes in the Arctic in recent years are profoundly affecting Arctic life.The northern Bering Sea provides critical habitat for large populations of such as sea ducks, gray whales, bearded seals and walruses, and all of these mammals depend on small bottom-dwelling creatures for sustenance. These bottom-dwellers, in turn, are accustomed to colder water temperatures and long periods of extensive sea ice cover. (47) However, "a change from arctic to sub-arctic conditions is under way in the northern Bering Sea," according to the researchers, and is causing a shift toward conditions favoring both water-column and bottom-feeding fish and other animals that until now have stayed in more southerly, warmer sea water.(48) As a result, the ranges of region’s typical inhabitants can be expected to move northward and away from the small, isolated Native communities on the Bering Sea coast that subsist on the animals. "We’re seeing that a change in the physical conditions is driving a change in the ecosystems," said JackieGrebmeier, a researcher at the University of Tennessee.Grebmeier said the new report is unusual in that it looks at the potential effects of changing climate in the Arctic primarily through a life-sciences lens, rather than an analysis of the physics of climate change. "It’s a biology driven, integrated look at what’s going," Grebmeier said. Grebmeier is chief scientist for the Western Shelf-Basin Interactions (SBI) research project, which conducted a series of research cruises to observe changes in the carbon balance of the offshore areas of the Alaskan Arctic and their effects on the food chain. The cruises included a number of researchers supported by the National Oceanic and Atmospheric Administration (NOAA), and other federal agencies. (49) NSF and NOAA also funded U.S. researchers who contributed data collected by the Bering Strait Environmental Observatory, which annually samples waters in the northern Bering Sea to assess the biological status of productive animal communities on the sea floor.(50) Those highly productive waters currently act as sponges for carbon dioxide, absorbing quantities of the gas that otherwise would remain in the atmosphere where it would be expected to contribute to warming. But, the researchers say, if the biological trends they observe in the northern Bering Sea persist and are not reversible, the accompanying shift in species and ecosystem structure could have important implications for the role of the sea as a "carbon sink". 49
Have you ever wondered whether writing and maintaining your business blog is a waste of time If you have, it probably is. Business blogs are valuable for some companies, but for many blogging takes up time and resources better spent elsewhere. If any of the following statements apply to you, stop posting to your blog (or re-purpose what you would have posted) and start doing something more productive:(41) You dread writing another post.Either way, whatever you publish will not represent your business well, so why do it Any time you feel you can’t put your best foot forward, don’t take the step.(42) Your page views are stagnant.Unless of course you can accurately identify tangible benefits from that readership.(43) You can’t quantify your return.Blogging is like any other investment in time and resources: If you don’t see a return, don’t do it.(44) Your goal is to provide valuable resources to customers.Potential customers who gladly read resource pages often run screaming from the same information when it appears on a blog.(45) Your readers are not your customers.Building an audience is useful only if the audience contains current and potential customers. Know who is reading your biog. If you can’t be bothered to find out, that’s yet another indication it’s time to stop.[A] Many business owners say, "I don’t have any numbers to back it up, but I know my blog is paying off." Really How If your blog isn’t sending significant traffic to your website via search engines, isn’t directly generating sales, doesn’t create a community, or creates a community that doesn’t actuallybenefit your business, your blog isn’t paying off.[B] If you aren’t excited by the thought of sitting down to write your next post, you have nothing to say and will once again borrow ideas from another blog, or already realize blogging is a waste of time but won’t admit it.[C] Great goal. By all means do it. But don’t put how-to information, or useful tips, or non-news information on your blog. Many people are blog-averse because most blogs are terrible, so your blog may automatically get painted with the same brush. If your material is relatively evergreen, create resource pages on your website instead.[D] When new posts average the same number of page views, and on a monthly basis so does your entire blog, you’ve stalled. Maybe loyal readers keep returning, or maybe you gain some and lose some, but either way not much is happening. A blog with a small stagnant readership is a blog that is a waste of time, at least for business purposes.[E] Never blog because you think it helps; you have to know. Knowing takes effort. If you’re not willing to put the time you need into tracking and analyzing data, you’re either lazy or afraid to find out you’re wasting your time on your blog. Sometimes quitting is more admirable than staying the course.[F] This happens more often than you think. For example, a friend is an incredibly successful financial planner. He writes a blog that gets thousands of unique visitors a month. But he writes about topics of interest only to other financial planners. That would be fine if his blog generated media opportunities, or supported a book he plans to write, or helps him network and bring in more business—but it doesn’t. 44
