The record of continental (as opposed to island) bird and mammal extinctions in the last five centuries was analyzed to determine if the “species-area” relationship actually works to predict extinctions. Very few continental birds or mammals are recorded as having gone extinct, and none have gone extinct from habitat reduction alone. No continental forest bird or mammal is… Read More »
The current debate is a public policy debate with enormous implications. It is no longer about climate. It is about the government, the politicians, their scribes and the lobbyists who want to get more decision making and power for themselves. It seems to me that the widespread acceptance of the global warming dogma has become one of the… Read More »
The impact of time?varying radiative forcing on the diagnosis of radiative feedback from satellite observations of the Earth is explored. Phase space plots of variations in global average temperature versus radiative flux reveal linear striations and spiral patterns in both satellite measurements and in output from coupled climate models.
Science is increasingly being manipulated by those who try to use it to justify political choices based on their ethical preferences and who are willing to suppress evidence of conflict between those preferences and the underlying reality. This problem is clearly seen in two policy domains, health care and climate policy.
The IPCC was formed in 1988 with the purpose of assessing “the scientific, technical and socioeconomic information relevant for the understanding of the risk of human-induced climate change.” — i.e. its main goal is based on the assumption of “human-induced climate change” – there was never an attempt to evaluate the scientific evidence of the cause.
We have had some extreme conditions the last few years – of cold, heat, snow and rain. Detailed summaries on the cold last winter can be found here and on the hot summer here. Both were memorable seasons indeed. Though the second author did an excellent job detailing the summer records and did mention the amplified and frozen… Read More »
Abstract: Perlwitz etal (2009) used computer model suites to contend that the 2008 North American cooling was naturally induced as a result of the continent’s sensitivity to widespread cooling of the tropical (La Nina) and northeastern Pacific sea surface temperatures. But they concluded from their models that warming is likely to resume in coming years and that climate… Read More »
Climate extremes and “disruptions” are nothing new under the sun.
Arctic stations near heat sources show warming over the last century. Arctic stations that are isolated from manmade heat sources show no warming.
News broke on or around 19 November 2009 that a large archive of emails and files from the Climatic Research Unit (CRU) in the UK had been released on the internet. The contents of the files were sufficiently disconcerting to the public, governments and university administrations that a number of inquiries were established. Several of my research projects… Read More »
