The world’s climate alarmists contend that CO2-induced global warming will lead to numerous extinctions of both plants and animals. Initially, this claim was based solely on models of how they thought Earth’s climate behaved in response to increases in various atmospheric greenhouse gases, contending that the increases in temperature predicted to result from projected increases in the air’s… Read More »
Environmental stresses induced by exposure to pollutants, drought, intense solar radiation and high air or water temperatures generate highly-reactive oxygenated compounds that damage both terrestrial and aquatic plants. Ameliorating these stresses typically involves the production of antioxidant enzymes that scavenge and detoxify the highly-reactive oxygenated compounds. Hence, when stresses are present, concentrations and/or activities of antioxidants in plants… Read More »
Climate alarmists predict global warming will increase human death rates, and nary a heat wave occurs but what they are quick to blame any concurrent excess deaths on the high temperatures associated with it. Much more deadly than hot weather, however, is cold weather; yet climate alarmists typically ignore the excess deaths that are caused by low temperatures,… Read More »
As living entities, corals are not only acted upon by the various elements of their environment, they also react or respond to them. And when changes in environmental factors pose a challenge to their continued existence, they sometimes take major defensive or adaptive actions to insure their survival.
By examining various properties of tree rings, researchers can deduce how historical increases in the air’s CO2 concentration have already affected tree productivity and water use efficiency.
Since October 1996 there has been no global warming at all (Fig. 1). This month’s RSS temperature plot pushes up the period without any global warming from 18 years 1 month to 18 years 2 months (indeed, very nearly 18 years 3 months). Will this devastating chart be displayed anywhere at the Lima conference? Don’t bet on it.
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… Read More »
In atmospheric CO2 enrichment experiments, nearly all plants almost always exhibit increases in photosynthetic rates and biomass production when environmental conditions are optimal for growth. Even when conditions are less than favorable (low soil moisture, poor soil fertility, high soil salinity, high air temperature), many plants still exhibit a CO2-induced growth enhancement; and that relative or percentage enhancement… Read More »
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… Read More »
According to the IPCC, CO2-induced global warming will be net harmful to the world’s marine species. This summary examines this hypothesis for various fish species, presenting evidence in opposition to the IPCC’s point of view.
