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 »

Historic Trends in Arctic Glacier Behavior

By | January 3, 2012

Computer simulations of global climate change have long indicated the world’s polar regions should show the first and severest signs of CO2-induced global warming. If the models are correct, these signs should be especially evident since the second half of the 20th century, when approximately two-thirds of the modern-era rise in atmospheric CO2 occurred and Earth’s temperature supposedly… Read More »

When Sea Level Change is Not Sea Level Change

By | November 22, 2011

Many claim sea level is rising because of global warming and point to changes along the Gulf of Mexico coast. Sea level has risen since the end of the last Ice Age (Figure 1), but it has slowed dramatically in the last few hundred years. However, shoreline change is not just a function of water level change. Misdirection… Read More »

Empirical Determination of Climate Sensitivity

By | September 29, 2011

By an astonishing 15 distinct methods, Christopher Monckton of Brenchley demonstrates in his latest SPPI technical paper that the warming we can expect in response to the doubling of CO2 concentration that is expected this century will not be 6 F, the IPCC’s central estimate, but only around 2 F.

How It Got So Hot … Hot It Got So Humid … How Cooling May Have Played A Role

By | July 26, 2011

The southern plains drought, followed the second strongest La Niña (behind only 1917/18) according to the Southern Oscillation Index (SOI), an atmospheric pressure based measure (standardized Darwin, Australia versus Tahiti surface pressure). Positive values are La Niña, negative El Niños. The April to April SOI showed the 1917/18 peak and 2010/11 close behind.

Estimates of Global Food Production in the Year 2050 – Will We Produce Enough to Adequately Feed the World?

By | June 30, 2011

Global food security is one of the most pressing societal issues of our time. Based on food production databases assembled and maintained by the United Nations, I have identified the specific crops that supply 95% of the food needs of the world, six large regions into which the world may be divided, twenty sub-regions, and twenty-five individual countries… Read More »
