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...]
Why 2014 was, and was not, the ‘hottest year in recorded history’
Media all over America and around the world have trumpeted the news: “2014 Was Hottest Year on Earth in Recorded History,” to quote the New York Times headline. The Times’s lead paragraph touted this as “underscoring scientific warnings about the risks of runaway emissions and undermining claims by climate-change contrarians that global warming had somehow stopped.” But it’s time to look below the surface—or, as you’ll see in a moment, above it. Let’s dispense with the simplest error … [Read more...]
2014 as the Mildest Year: Why You Are Being Misled on Global Temperatures, OR: Why I Should Have Been an Engineer Rather than a Climate Scientist
I’ve been inundated with requests this past week to comment on the NOAA and NASA reports that 2014 was the “hottest” year on record. Since I was busy with a Japan space agency meeting in Tokyo, it has been difficult for me to formulate a quick response. Of course, I’ve addressed the “hottest year” claim before it ever came out, both here on October 21, and here on December 4. In the three decades I’ve been in the climate research business, it’s been clear that politics has been driving the … [Read more...]
Global Warming: Powerful New Evidence Surfaces That Contradicts Manmade Claims
On the heels of the Vatican's announcement that the Pope intends to urge support for an international agreement to fight global warming by reducing human emissions of carbon dioxide (CO2) from fossil-fuel energy use, a new peer-reviewed scientific paper reveals powerful evidence that CO2 emissions contribute far less to global warming than widely thought. The paper, "Why models run hot: results from an irreducibly simple climate model," appeared in the January 8 edition of Science Bulletin … [Read more...]
