Coaxing Nature to Reveal 1,000 Years of Earth’s Climate

By Larry O’Hanlon, Globe Correspondent. This story appeared in the Boston Globe, May 20, 2003, page C9. The 20th century may not have been so extraordinarily hot after all, according to a climate study of the last thousand years, which confirms historical accounts of fig trees growing in Germany and early grape harvests in England […]

Lessons & Limits of Climate History: Was the 20th Century Climate Unusual?

A survey of the scientific literature shows that 79 of the 102 proxy temperature studies identified a 50-year period during the past millennium that was warmer than any 50 years in the 20th century. While these results do not allow estimation of globally-averaged surface temperature for the past 1,000 years, they are strong evidence that the temperatures experienced during the 20th century were not unusual.

Reconstructing Climatic and Environmental Changes of the Past 1000 Years: A Reappraisal

The 1000-year climatic and environmental history of the Earth contained in various proxy records is examined. As indicators, the proxies duly represent or record aspects of local climate. Questions on the relevance and validity of the locality paradigm for climatological research become sharper as studies of climatic changes on timescales of 50–100 years or longer […]

Calculating the Climatic Impacts of Increased CO2: The Issue of Model Validation

Some Difficulties in Simulating Climate Variables Temperature (Surface, Troposphere and Stratosphere) Precipitation Clouds Expected Outcomes of CO2 Forcing The range of modeled global warmings for CO2 doubling Non-robustness of predicted changes for North Atlantic thermohaline circulation Comments Good morning! My name is Willie Soon.  Before I start, let me first acknowledge that this presentation is […]

The Sun Also Warms

Recent discoveries that shed light on the possible influence of the Sun on the climate of the Earth owe to experiments and instruments born of high technology and launched into space. They have provided us with new ideas about the nature of changes in Sun’s light, its charged particle emissions, and how they both affect […]

Solar Variability and Climate Change

The purpose of this article is to give you some details about the research which my colleagues (especially Sallie Baliunas and Eric Posmentier) and I have done in studying the controversial relationship between the Sun’s energy output and Earth?s temperature, in short, the sun-climate connection. Despite what you may have heard before about sun-climate studies, […]

Increasing Carbon Dioxide and Global Climate Change

No evidence can be found for catastrophic global warming from the recent rise in the air’s carbon dioxide content as a result of human activities. The elevated carbon dioxide concentration in the air has, however, had a positive impact on plant growth.
