Understanding Visual Exhibits in the Global Warming Debate

By | March 29, 2008

Abstract: With a lack of traditional science, partisans on both sides, and enormous consequences depending on popular opinion and political will, it is important that people understand the evidence in the debate over global warming. Unfortunately, most people do not have the time, desire, or ability to undertake an independent study of the issues. Recognizing this, advocates have… Read More »

Correction to: A 2000 Year Global Temperature Reconstruction Based on Non-tree ring proxies

By | February 12, 2008

A climatic reconstruction published in E&E (Loehle, 2007) is here corrected for various errors and data issues, with little change in the results. Standard errors and 95% confidence intervals are added. The Medieval Warming Period (MWP) was significantly warmer than the bimillennial average during most of the period 820 – 1040 AD. The Little Ice Age was significantly… Read More »

Environmental Effects of Increased Atmospheric Carbon Dioxide

By | January 24, 2008

A review of the research literature concerning the environmental consequences of increased levels of atmospheric carbon dioxide leads to the conclusion that increases during the 20th and early 21st centuries have produced no deleterious effects upon Earth’s weather and climate. Increased carbon dioxide has, however, markedly increased plant growth. Predictions of harmful climatic effects due to future increases… Read More »

Unresolved issues with assessment of global surface temperature trends

By | December 28, 2007

This paper documents various unresolved issues in using surface temperature trends as a metric for assessing global and regional climate change. A series of examples ranging from errors caused by temperature measurements at a monitoring station to the undocumented biases in the regionally and globally averaged time series are provided….

A Comparison of Tropical Temperature Trends with Model Predictions

By | December 11, 2007

ABSTRACT: We examine tropospheric temperature trends of 67 runs from 22 ‘Climate of the 20th Century’ model simulations and try to reconcile them with the best available updated observations (in the tropics during the satellite era). Model results and observed temperature trends are in disagreement in most of the tropical troposphere, being separated by more than twice the… Read More »

A Fundamental Scientific Error in “Global Warming

By | November 30, 2007

On page 18 of Laurie David’s new children’s global warming book, there is a glaring scientific error. David tells children: Deep down in the Antarctic ice are atmosphere samples from the past, trapped in tiny air bubbles. These bubbles, formed when snowflakes fell on the ice, are the key to figuring out two things about climate history: what… Read More »

Marlo Lewis examines Al Gore’s An Inconvenient Truth.

By | July 19, 2007

An Inconvenient Truth (AIT), Vice President Al Gore’s book on “The planetary emergency of global warming and what can be done about it,” purports to be a non-partisan, non-ideological exposition of climate science and moral common-sense.
