Background Dimethylsulfide or DMS, to quote the authors, "is produced by marine phytoplankton activity, and its content in the surface mixed layer is supersaturated with respect to the atmosphere," so that "the net flux of DMS is driven from sea to air." This fact is very important because, as they continue, "in the atmosphere, DMS is rapidly oxidized… Read More »
Landsea reports that Mann and Emanuel (2006) used quantitative records stretching back to the mid-nineteenth century to develop "a positive correlation between sea surface temperatures and Atlantic basin tropical cyclone frequency for the period 1871-2005…"
[SPPI Note: Here we have the classic pattern. Government employees churning out computer modelled reasons – not real world data or experiences – to expand government size and power. While all the while, exactly the opposite is really taking place.]
The New York Times sets the stage for a new movie, scheduled to open in the coming weeks, called “Arctic Tale” – a fictitious account of the struggle of polar bears and walruses against a changing climate.
Background There is growing concern that it will be difficult to feed the expanding human population of the planet just a few decades from now without the taking of great quantities of land (Waggoner, 1995; Tilman et al., 2001, 2002; Huang et al., 2002) and nearly all available freshwater resources (Wallace, 2000) from what might be called "wild… Read More »

What was done Employing open-top chambers, the authors determined net ecosystem CO2 exchange (NEE) before, during, and after the severe Central Florida drought of 1998 in a scrub-oak ecosystem in ambient-CO2 (AC) air and in elevated-CO2 (EC) air that had been enriched with an extra 350 ppm of CO2 since May 1996, focusing on the ecosystem’s dominant species… Read More »
What was done The authors made spatially and temporally intensive measurements of atmospheric CO2 concentration across an urban-to-rural CO2 gradient comprised of Salt Lake City’s downtown business district, a residential neighborhood, and a non-urbanized rural location within the Salt Lake Valley (Utah, USA) from 2004 to 2006, as well as measurements of CO2 and water isotopic composition at… Read More »
What was done The authors analyzed the vertical distributions of diatoms, silicoflagellates and biogenic silica found in two sediment cores recovered from the inner and outer basins (49°04’N, 125°09’W and 49°02’N, 125°09’W, respectively) of Effingham Inlet, British Columbia, Canada, describing the climatic implications of what they found.
Global Warming: A private firm’s downgrade of its hurricane forecast raises an obvious question: If scientists can’t get near-future projections in a limited area right, how can they predict the climate decades from now?
