production, former state energy construction czar under Gov. Gray Davis (2001): I commend the Register for adding the qualifier in the Oct. 10 Associated Press climate-model speculation article that noted that the article's conjecture on climate change depends solely on scientifically unvalidated and unproven computer models [“Study: Earth's climate to shift soon,” News].
Nevertheless, the Register has yet to publish a news article addressing the failure of the United Nations Intergovernmental Panel on Climate Change Assessment Report 5 climate models, which represents the fifth generation of updated attempts at creating computer analyses intended to project the Earth's greenhouse climate sensitivity and temperature behavior.
Not only have the most recent and advanced climate models failed to project global temperatures, but after more than 20 years of effort, costing billions of dollars, the latest U.N. climate report's assessment of the Earth's climate sensitivity to CO2 emissions is as large and undefined now as it was more than two decades ago.
Numerous studies show it is impossible to create global climate and weather models that have any validity for long-term periods.
Numerous scientifically peer-reviewed studies now show that natural climate variation is responsible for the behavior of Earth's climate and temperatures. The newest peer-reviewed study demonstrating natural variability as the climate driver is authored by climate scientist Judith Curry and is published in “Climate Dynamics.”
Additionally, Curry has provided analysis on many more peer-reviewed studies that show the clear connection between natural-climate variations associated with regularly occurring long-term ocean temperature cycles as the primary driver of global climate.
Furthermore, in her ongoing analysis, of the U.N. IPCC AR5 report she has found that the report concludes that prior IPCC report, concerns of abrupt and irreversible climate changes were overstated. The present report indicates such changes are unlikely to occur. There is no “tipping point” climate emergency at hand.
In the past few months there have been two peer-reviewed studies of Antarctica published in Geophysical Research Letters and the Journal of Geophysical Research. The GRL study determined that there is a natural climate variability cycle some 308 years in duration that drives West Antarctica's periodic warming and melting that is unrelated to any impacts driven by man-made actions.
The JGR study found that East Antarctica, which comprises more than 80 percent of the continent's massive ice extent, has experienced increasing ice mass over the last three decades.
Much is happening in the world of peer-reviewed scientific studies that does not support speculative, computer-model man-made climate alarmism but instead, powerfully points to natural climate variation as the primary driver of the Earth's climate behavior. Register readers deserve more for climate news than biased climate articles.
Storming our climate
NEWPORT BEACH, Mark Tabbert, founding member, Orange County Citizens Climate Lobby: Robert M. Duncan, the CEO of Clean Coal, makes a very important admission in his letter, “Coal tech needs time” [Oct. 8], when he says that “Carbon Capture and Storage technology holds the future for fossil-fuel based energy.” Translated, he is saying that unless we learn to capture and store carbon, we can't continue to burn fossil fuels. Truer words were never spoken, if we care about a healthy and sustainable future.
The rest of his letter argues that President Barack Obama is rushing things. Duncan wants to keep burning coal and rely on his hope that we will develop CCS that is economical but he is only thinking of his bottom line. The truth is we should have eliminated the use of coal long ago.
I read in the same Register issue about the latest devastating climate event, a record-breaking snow storm with four feet of snow in parts of South Dakota that also produced tornadoes in Colorado and Wyoming [“Devastating storm,” News, Oct. 8]. Four people died and the loss of livestock “will be felt for years.”
This is just the latest unusual weather event in our back yard. Similar events are happening around the world. Duncan needs to listen to what oil executives are talking about – the need for a carbon tax. Exxon's CEO, Rex Tillerson, says he believes, “the American people want climate policy to be transparent, honest, and effective. ... I firmly believe it is not too late for Congress to consider a carbon tax as the better policy approach.”
