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 »
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 »
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 »
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….
This study assesses near surface lapse rates and temperatures over the past decade at two heights from the Oklahoma Mesonet. A statistically significant change in lapse rate was detected of _0.21 ± 0.09_C (10 m)_1 per decade. The trend of nighttime lapse rate was about three times larger than the magnitude of trend of the daytime lapse rate.… Read More »
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 »
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 »
It seems that weekly, if not daily, Americans are faced with new alleged hazards to their health and environment.
Carbon Dioxide and Global Change: Separating Scientific Fact from Personal Opinion
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.
