Ten Years’ “Accelerated Global Warming”? No, Mr. President!

By | July 23, 2013

During the July 2013 U.S. Senate hearing at which Roger Pielke Jr. and Roy Spencer gave stellar testimony to the visible discomfiture of the climate-extremist witnesses, none of the Democrat Senators and none of those they had chosen to testify before them was at all anxious to defend Mr. Obama’s assertion that over the past decade global warming… Read More »

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 »

Solar and Planetary Oscillation, Control on Climate Change: Hind-cast, Forecast and a Comparison of the CMIP5 GCMs

By | July 18, 2013

ABSTRACT Global surface temperature records (e.g. HadCRUT4) since 1850 are characterized by climatic oscillations synchronous with specific solar, planetary and lunar harmonics superimposed on a background warming modulation. The latter is related to a long millennial solar oscillation and to changes in the chemical composition of the atmosphere (e.g. aerosol and greenhouse gases). However, current general circulation climate… 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 »
