Biofuels: Land and Water Concerns

By | May 7, 2014

Biofuels are fuels made from organic matter. They include liquid fuels such as ethanol, biodiesel, and methanol; gaseous fuels such as methane and carbon monoxide; and solid fuels such as biochar and the more traditional charcoal. Biofuels may have some environmental advantages over gasoline and diesel fuels, but they are more expensive to produce and cannot supply more… Read More »

Medieval Warm Period in Upper North America

By | April 16, 2014

Climate alarmists claim that rising atmospheric CO2 concentrations due to the burning of fossil fuels, such as coal, gas and oil, have raised global air temperatures to their highest level in the past one to two millennia. And, therefore, investigating the possibility of a period of equal global warmth within the past one to two thousand years has… Read More »

Can Plants Evolve Fast Enough to Cope with Increased Drought?

By | April 16, 2014

Evolution is generally thought of as acting over long periods of time. So is there anything it can do to help plants cope with the rapid climate changes that the IPCC predicts will be caused by the ongoing rise in the air’s CO2 content? In what follows, this question is carefully considered as it applies to the daunting… Read More »

Health Promoting Effects of Elevated C02 on Common Food Plants

By | April 16, 2014

How will the ongoing rise in the air’s CO2 content alter the amounts of various health-promoting substances found in the plants that we commonly eat? Studies of the effects of atmospheric CO2 enrichment on the quality of the different plants that comprise our diets have typically lagged far behind studies designed to assess the effects of elevated CO2… Read More »

Response of Corals to Ocean Acidification

By | April 16, 2014

It has been predicted that rates of coral calcification, as well as the photosynthetic rates of their symbiotic algae, will dramatically decline in response to what is typically referred to as an acidification of the world’s oceans, as the atmosphere’s CO2 concentration continues to rise in the years, decades, and centuries to come. As ever more pertinent evidence… Read More »

Effects of Ocean Acidification and Warming on Marine Echinoderms

By | March 20, 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 such studies of echinoderms, highlighting several studies that challenge the alarming and negative projections of the IPCC on… Read More »

Effects of Elevated C02 on Soil Carbon Sequestration

By | March 12, 2014

It is important to note at the outset that atmospheric CO2 enrichment typically has but a small effect on the decomposition rates of senesced plant materials present in soils; yet this fact often leads to significantly greater soil carbon sequestration, as demonstrated by De Angelis et al. (2000), who reported a 4% reduction in the decomposition rate of… Read More »

Biospheric Productivity in South America

By | March 6, 2014

How will the terrestrial vegetation of South America respond to global warming and atmospheric CO2 enrichment? Climate alarmists suggest there will be widespread declines in both ecosystem size and productivity. But are these predictions correct? Given the fact that over the past century the Earth has experienced what alarmists refer to as unprecedented rises in both atmospheric temperature… Read More »

Killing Wildlife in the Name of Climate Change

By | March 1, 2014

The facts show that federally subsidized efforts that are being undertaken to, in theory, address climate change, are damaging America’s wildlife. Furthermore, those same efforts have, for years, been allowing an entire industry to avoid federal prosecution under some of America’s oldest wildlife laws.

Natural Resource Adaptation: Protecting Resources and Economies

By | March 1, 2014

There is no scientific proof that human emissions of carbon dioxide (CO2) are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years. If there were such a proof it would be written down for all to see. No actual proof, as it is understood in science, exists.
