How Flowers Respond to Rising Atmospheric C02

By | April 27, 2012

Nearly all of Earth’s plant life responds favorably to increases in the air’s CO2 content by exhibiting enhanced rates of photosynthesis and biomass production. But what about other plant characteristics? How do they respond to rising atmospheric CO2? The present review investigates what scientists have learned with respect to plant floral features.

Beyond Biomass: Atmospheric C02 Enrichment and Crop Seeds

By | April 18, 2012

When dealing with agricultural commodities such as grain crops, seeds comprise the yield; and in such cases, the biomass of one is the biomass of the other. Hence, when looking for effects of elevated CO2 on the seeds of such crops, one is naturally interested in something more than just their final biomass; and there are a number… Read More »

Interactive Effects of C02 and Phosphorus on Plant Growth

By | April 11, 2012

Under current ambient conditions, plant growth and development are typically carbon-limited, which is why plants generally exhibit increased growth and biomass production in response to atmospheric CO2 enrichment. Next to carbon, nitrogen is usually the second most limiting nutrient to plant growth, followed by phosphorus. Thus, although it is a less significant component of plant tissues than carbon… Read More »

Global Biospheric Productivity: The Distant and Historic Past

By | April 4, 2012

Among the many alarmist fears of CO2-induced global warming is the concern that the productivity of the biosphere will decline if global temperatures rise to the extent predicted by computer models. Because of this concern, several researchers have investigated the relationship between temperature, atmospheric CO2, and biospheric productivity across a range of spatial and temporal scales. The present… Read More »

Interactive Effects of CO2 and Pathogens on Agricultural Plants

By | March 30, 2012

As the air’s CO2 content continues to rise, nearly all of Earth’s plants should continue to exhibit increasing rates of photosynthesis and, as a result, increased biomass production. But what about plants that are suffering from various pathogen-induced diseases? Will they be able to reap the benefits of the many positive effects of atmospheric CO2 enrichment? We have… Read More »

Global Warming, Coral Reefs and Symbiont Shuffling

By | March 22, 2012

In light of the many recent observations, the prospect of earth’s corals being able to successfully cope with the possibility of further increases in water temperatures, be they anthropogenic-induced or natural, appears more than likely, if not altogether certain. Corals have survived such warmth — and worse — many times in the past, including the Medieval Warm Period,… Read More »

Lisa P Jackson – EPA Administrator: Fulfilling the UN Mission

By | March 22, 2012

The EPA is effectively no longer under the control of the US Congress; its allegiance is to the UN and implementation of the policies of Sustainable Development via Agenda 21. It has considerable involvement in the IPCC reports and claims the UN body as a peer reviewed authority, in pursuing ever more rigorous controls of “CO2 pollution”, to… Read More »
