Observed climate change in Colorado

By | July 21, 2013

Annual temperature: The historical time series of statewide annual temperatures in Colorado begins in 1895. Over the entire record, there has been an upward trend, which has resulted in temperatures in the early 21st century being about 2ºF warmer than temperatures 100 years ago. Despite this long-term rise however, the record continues to be largely dominated by annual… Read More »

Impact of Global Warming and Rising C02 on Methane Emissions from Natural Vegetation

By | July 12, 2013

What impact do global warming, the ongoing rise in the air’s carbon dioxide (CO2) content and a number of other contemporary environmental trends have on the atmosphere’s methane (CH4) concentration? The implications of this question are substantial, in light of the fact that methane is a more powerful greenhouse gas, molecule for molecule, than is carbon dioxide. We… Read More »

Evidence of Medieval Warm Period in Russia

By | June 28, 2013

The Medieval Warm Period (MWP) was a global climatic anomaly that encompassed a few centuries on either side of AD 1000, when temperatures in many parts of the world were even warmer than they are currently. The degree of warmth and associated changes in precipitation, however, varied from region to region and from time to time; and, therefore,… Read More »

Pacific Ocean Hurricane’s and Global Warming

By | June 26, 2013

Have hurricanes of the Pacific Ocean become more numerous and intense over the past century or so, in response to what climate alarmists typically describe as unprecedented global warming? To provide a firm foundation for answering this important question, this summary contains brief synopses of several real-world (as opposed to climate-model) studies that have appeared in the peer-reviewed… Read More »

Effects of C02 on Nitrous Oxide Emissions

By | June 13, 2013

In the words of Cantarel et al. (2011), nitrous oxide (N2O) is “an influential greenhouse gas,” with a per-molecule global warming potential “approximately 300 times that of CO2 (IPCC, 2001),” and they say it “has shown linear increases of 0.2-0.3% per year over the last few decades, largely as a result of changes in agricultural practices and direct… Read More »

Interactive Effects of C02 and Temperature on Woody Plant Growth

By | June 5, 2013

As the atmosphere’s CO2 concentration continues to rise, most trees will likely exhibit increased rates of photosynthesis and biomass production, which can subsequently lead to an increase in the amount of timber that will likely be required to meet the growing needs of earth’s expanding human population. However, some individuals have predicted that CO2-induced global warming will counteract… Read More »

Climatic Effects of Black Carbon

By | May 22, 2013

Writing as background for their work, Kaspari et al. (2011)[1] state that “black carbon (BC, the absorbing component of soot) produced by the incomplete combustion of biomass, coal and diesel fuels can significantly contribute to climate change by altering the Earth’s radiative balance,” noting that “BC is estimated to have 55% of the radiative forcing effect of CO2… Read More »

Interactive Effects of Temperature and Enhanced C02 on Agricultural Crops

By | May 21, 2013

As the air’s CO2 content rises, most plants exhibit increased rates of photosynthesis and biomass production (see our Plant Growth Database[1]), which should enhance the amount of food, fiber and timber production that can be utilized to feed, clothe and shelter earth’s expanding human population. However, some individuals have suggested that the growth-promoting effects of atmospheric CO2 enrichment… Read More »
