You would think tropical species like warm weather – and what’s the difference between warm and 2 or 3 degrees warmer. Well, they can be picky. A short appendix to our previous article – a bit of supporting theory as … Continue reading →
In our series ‘Understanding Sea Level Rise’ we’ve paid ample attention to positive melting feedbacks, mechanisms that accelerate ice melt and ice sheet dynamics as global temperatures keep rising. Now of course there are also negative feedbacks, like local relative … Continue reading →
Quickly migrating species can keep track of climate change by migrating along the optimum of their climate zone habitat. Paradoxically these species increase the pressure on slower dispersers, increasing their extinction risk. Overall, adding such complex interspecies interaction to models … Continue reading →
Warmer water and reduced river flows in the United States and Europe in recent years have led to reduced production, or temporary shutdown, of several thermoelectric power plants. For instance, the Browns Ferry Nuclear Plant in Alabama had to shut down more than once last summer because the Tennessee River’s water was too warm to use it for cooling.
Fishing for herring, anchovy, and other “forage fish” in general should be cut in half globally to account for their critical role as food for larger species, recommends an expert group of marine scientists in a report released today. The Lenfest Forage Fish Task Force conducted the most comprehensive worldwide analysis of the science and management of forage fish populations to date. Its report, “Little Fish, Big Impact: Managing a crucial link in ocean food webs,” concluded that in most ecosystems at least twice as many of these species should be left in the ocean as conventional practice.
