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.
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 »
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 »
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 »
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 »
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 »
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 »
One of the great horror stories associated with predictions of CO2-induced global warming is that the warming will be so fast and furious that many species of plants will not be able to migrate towards cooler regions — poleward in latitude, or upward in elevation — at rates that are rapid enough to avoid extinction. This claim may… Read More »
Debris flows are a type of mass movement that frequently cause major destruction in alpine areas. Because debris flows are generally the product of heavy precipitation events, and because climate models project a future increase in the frequency and/or intensity of extreme precipitation events in consequence of CO2-induced global warming, many have become alarmed that such disastrous earthen… Read More »
One of the perceived great tragedies of CO2-induced global warming is that rising temperatures will increase the development, transmission, and survival rates of parasites in general, leading to a perfect storm of biological interactions that will raise the prevalence of parasitic disease among animals in the future. But is this really so?
