Atmospheric CO2 Enrichment: Fighting the Effects of Drought

By | August 6, 2007

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 »

A 5000-Year History of Ocean and Climate Conditions Along Vancouver Island, British Columbia, Canada

By | August 6, 2007

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.

Salt Lake City (USA) Urban-to-Rural CO2 Gradient

By | August 6, 2007

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 »

Tempest in a Teapot

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?
