Simultaneous Ocean Acidification and Warming (Effects on Marine Animals: Miscellaneous) -- Summary (25 November 2014)
Most of the ocean acidification research conducted to date has focused solely on the biological impacts of declining seawater pH. Few studies have investigated the interactive effects of ocean acidification and temperature. This summary examines what has been learned in several such studies of various marine organisms that challenge the alarming and negative projections of the IPCC on the matter...

Global Warming Not Influencing Annual Streamflow Trends in the Southeast and Mid-Atlantic United States (21 November 2014)
Climate model simulations generally predict a future with more frequent and more severe floods in response to CO2-induced global warming. Confirming such predictions with real world observations, however, has remained an elusive task. The latest study to illustrate this point comes from the four-member research team of Barros et al. (2014), who writing in the Journal of Hydrologic Engineering analyzed streamflow records at various locations throughout the southeast and mid-Atlantic United States over the past century...

Forest Topsoil Carbon Content: The Outlook for China and Beyond (17 November 2014)
The combination of (1) soil carbon accumulation and (2) vegetation carbon sequestration observed in various locations across the globe is triggering "a negative feedback to climate warming, rather than the positive feedback predicted by coupled carbon-climate models"...

Ocean Acidification (Effects on Marine Animals: Fish) -- Summary (14 November 2014)
As the air's CO2 content rises in response to ever-increasing anthropogenic CO2 emissions, and as more and more carbon dioxide therefore dissolves in the surface waters of the world's oceans, theoretical reasoning suggests the pH values of the planet's oceanic waters should be gradually dropping. The IPCC and others postulate that this chain of events, commonly referred to as ocean acidification, will cause great harm -- and possibly death -- to marine life in the decades and centuries to come. However, as ever more pertinent evidence accumulates, a much more optimistic viewpoint is emerging. This summary examines the topic of the potential impacts of ocean acidification on fish...

Plant Growth Database (14 November 2014)

Temperature-Related Deaths in a Warming World (13 November 2014)
Over the course of 20th-century global warming, daily minimum temperatures typically rose at a rate that was fully three times greater than the rate of daily maximum temperature rise over most of the world, which resulted in a significant reduction in diurnal temperature range throughout the better part of the inhabited portions of the planet over that time period, which reduction likely significantly reduced the percentage of the human population dying each year from the various health challenges listed in this study...

Individual and Combined Effects of Warming and Ocean Acidification on Young Corals (12 November 2014)
The consequences of the "double whammy" are not what you might think they would be, as the authors of this study reveal there was "no consistent effect of elevated pCO2 on fertilization, development, survivorship or metamorphosis, neither alone nor in combination with temperature" of two important Great Barrier Reef corals...

Could the cold-water fish handle the heat if Earth's temperature were to begin to rise once again?...

Plants Climbing Mountains in Warming and CO2-Accreting Air (12 November 2014)
Former NASA scientist James Hansen has claimed in the past - in testimony before a committee of the U.S. House of Representatives, no less - that in response to CO2-induced global warming, plant life in alpine regions is "in danger of being pushed off the planet," as it gradually migrates upward in elevation in response to increasing temperatures. At first glance, this contention does not seem all that unreasonable. In fact, it actually sounds logical. But when assessed in "real time" in the real world, it is found to be something quite different...

Australia's "Big Dry" or "Millennium Drought" in New Perspective (11 November 2014)
