The essence of science is testing predictions by comparison with real-world observations. Al Gore and the IPCC have been saying for years that human emissions of CO2 would cause global warming at a rate of 3C per century. But IPCC's forecasts violated 72 out of 89 relevant principles of scientific forecasting. In 2007, Scott Armstrong, professor at the Wharton School and a specialist in forecasting methods, challenged Gore to a bet. They would track changes in global average temperature (GAT) … [Read more...]
Richard Keen: The Science Is Settled
Richard Keen, Ph.D., Emeritus Professor of Atmospheric Science, University of Colorado, Boulder, put it bluntly in a recent personal communication: Climate Science has degenerated into a league of collaborators who suppress evidence, stifle dissent, censor unwelcome facts, and control the funding purse strings, all in the name of "settled science." In a way, the science is settled---the forecasts of catastrophic global warming are irreversibly wrong. Over the past 30 year the evidence of human … [Read more...]
“Global warming really has become a new religion”–Nobel Physicist Ivar Giaever
Ivar Giaever explains in this video lecture why he rejects global warming alarming. "It's ridiculous," he says, to think we can measure global average temperature (GAT) accurately, and that we should consider an increase in GAT from ~1880 to 2015 from ~288 degrees Kelvin to ~288.8 degrees Kelvin (an increase of only 0.3%) frightening. There's much more in this brilliant lecture. But who cares what he thinks? He's just a Nobel Prize-winning physicist. And after all, he's not a member of the … [Read more...]
Validation of IPCC’s Global Warming Forecasts would Require More than Tripling Warming Rate
At +0.11C per decade rate, Global Average Temperature would rise 1.1C in a century, not the ~3C generally predicted by IPCC without CO2 emission reduction. Actual increase in the 36.5 years since 1978 is 0.407C. To wind up with 3C increase in the century from 1978 through 2077, we'd need to add another 2.593C in the remaining 63.5 years, i.e., 0.41C per decade, 3.7 times the rate so far. Anybody got a good idea what's going to drive that more-than-tripling of the rate of increase? Or might it … [Read more...]
Fear Not, Climate Alarmism Unfounded
In my position as environmental manager for one of the largest university systems in the U.S., I regularly make it a point to ask scientists and engineers working in the real world, solving real day-to-day problems and stewarding our natural resources and environment, about their professional views on the issues of climate and energy. Their responses almost uniformly reflect disagreement with, practically a disdain for, the climate alarmists’ and sustainability activists’ premise that manmade … [Read more...]
Why do I Think Climate Alarmists Are Overreacting?
Religion Dispatches posted Jacob J. Erickson’s interesting article “Falling in Love with the Earth: Francis’ Faithful Ecology,” about a week ago, and one follower, “Whiskyjack,” chastened Catholic Republican Presidential candidates for hypocrisy on the grounds that they accept his authority on abortion and homosexuality but not on climate change. I replied: Catholic dogma holds that papal authority is only in matters of faith (doctrine) and morals. It doesn't extend to science, economics, or … [Read more...]
Estimates of climate sensitivity falling
Just came across this, and it's stunning. Those who charge CAGW skeptics with being anti-science need to take a look at this and consider carefully: Who's been trending right about how much warming comes from adding CO2 to the atmosphere? For in-depth discussion, see Nicholas Lewis, "Pitfalls in climate sensitivity estimation," Part 1, Part 2, and Part 3. Featured image from https://landshape.wordpress.com/2015/06/20/6921/. … [Read more...]
Oh, No! Polar Sea Ice Extent Is …
... pretty much stable. That's according to the most recent NASA data on polar sea ice extent, shown in this graph, posted by the University of Illinois's Department of Atmospheric Sciences: James Taylor comments: Updated NASA satellite data show the polar ice caps remained at approximately their 1979 extent until the middle of the last decade. Beginning in 2005, however, polar ice modestly receded for several years. By 2012, polar sea ice had receded by approximately 10 percent from … [Read more...]
Did Manmade Climate Change Cause Syria’s Civil War and the Rise of ISIS?
This article was originally published in The Christian Post. A new paper, Climate change in the Fertile Crescent and implications of the recent Syrian drought, PNAS, March 2, 2015, summarized its findings by saying, "the 2007-2010 drought contributed to the conflict in Syria. It was the worst drought in the instrumental record, causing widespread crop failure and a mass migration of farming families to urban centers." It went on to say, "Century-long observed trends in precipitation, … [Read more...]
To Divest or Not to Divest—That is the Question
“To be, or not to be? That is the question.” With those words Hamlet pondered suicide. That’s a question we should ask as we ponder shrill calls on various college campuses for divestment from fossil fuels – as took place this past weekend as part of Global Divestment Day. For with the end of fossil fuel use comes the eventual death of a significant portion of the human race. Yes, I just said that. And it’s true. 1.3 billion people live without electricity across the world, 2.6 billion lack … [Read more...]
