Polar bear expert Susan Crockford explodes the myth that global warming threatens polar bears in a new video from the Global Warming Policy Foundation. The numbers tell the story: global polar bear population has risen to over 30,000 despite decline in summer Arctic sea ice extent. … [Read more...]
Second Warmest February in 123 Years for Contiguous U.S.—Ho Hum
NOAA (National Oceanic and Atmospheric Administration) eagerly reported March 8 that February was the second warmest February in the last 123 years for the contiguous U.S. Various news media played it up. More evidence of dangerous, manmade global warming! (Except that of course warming is only evidence of warming, not of manmade warming. And the contiguous U.S. is not equal to the globe.) See http://www.nsstc.uah.edu/data/msu/v6.0/tlt/uahncdc_lt_6.0.txt for the satellite data (which goes … [Read more...]
This changes everything!
"Consensus" climate science has for decades assumed that the vast majority of the increase in atmospheric concentration of carbon dioxide (from about 280 parts per million by volume [ppmv] before the Industrial Revolution to about 400 today) has come from burning fossil fuels for energy. On that assumption, "consensus" scientists have alleged that human activity has driven all or most global warming over that time. Most criticism of that thinking has focused on "climate sensitivity"---how … [Read more...]
Judith Curry confirms: climate models can’t justify policy—ANY policy
For years we at the Cornwall Alliance have been saying that the disagreement between model predictions (or projections or simulations, call them what you will) of global temperatures and real-world observations means the models are invalidated and therefore provide no rational basis for predictions of future temperature and therefore no rational basis for policies meant to respond to such predictions. Now one of the world's leading climatologists, recently retired Professor Judith Curry, Chair … [Read more...]
Does the Trump Administration Put Science in Jeopardy?
It's hard to imagine a more thoroughly ignorant statement than this: “The discipline of science is one where the facts, once they are peer-reviewed and published in scientific journals, are fixed. They’re not open to interpretation, or at least not much.” That's the opinion of Jeffrey Kluger and Justin Worland, writing in "How a war on science could hurt the U.S.---and its citizens." in Time magazine. The truth, of course, for these two apparent neophytes to science, is quite the … [Read more...]
Has NOAA’s “Pausebuster” Been Busted?
“The one who states his case first seems right, until the other comes and examines him.”—Proverbs 18:17 Major news outlets and the climate change-focused blogosphere erupted over the last few days with the The Daily Mail’s publication February 4 of David Rose’s “Exposed: How world leaders were duped into investing billions over manipulated global warming data.” Rose reported serious data mishandling behind a study published in Science (Karl et al.) in 2015 by NOAA’s Tom Karl, Thomas … [Read more...]
Did the Pause End, or Did El Niño Interrupt It?
While reading Cornwall Alliance Senior Fellow Dr. Roy W. Spencer's "UAH Global Temperature Update for January, 2017: +0.30 deg. C," I happened to notice that the anomaly for the globe as a whole for January 2017 was identical to that of January 2015, at 0.3˚C. Then I eyeballed the anomalies for the intervening months in the table Roy provided and noticed quickly how prominently the effect of the super-El Niño that ran from late 2015 through most of 2016 was. In light of widespread questions … [Read more...]
Seeing Red—New NASA Climate Change Video Uses Questionable “Data” for Colorful Deception
A visitor to Cornwall Alliance's Facebook page recently asked our thoughts on a new video from NASA purporting to demonstrate that global warming is happening rapidly and that there's been no slow-down, let alone "pause," in the last two decades. Among other media, Huffington Post featured the video in an article titled "NASA Climate Change Video Shows Just How Quickly the Earth Is Warming." As is typical, the video uses frightening graphics to communicate numbers that are far less than … [Read more...]
The Trump Climate Dump: Why It Doesn’t Matter if Even 100% of Scientists Agree on Global Warming
Given current technologies, it makes no sense to destroy $100 Trillion in wealth this century for an unmeasurable reduction in warming. The more efficiently we can do those things, the greater humanity prospers. Affordable energy is part of that efficiency. Everything humans do requires energy. Everything. But when human prosperity suffers, people die. So, can it really be called “anti-science” that the moment Trump was inaugurated, the White House deleted all references to climate … [Read more...]
Climate Science or Climate Advocacy?
For almost thirty years, I have taught climate science at three different universities. What I have observed is that students are increasingly being fed climate change advocacy as a surrogate for becoming climate science literate. This makes them easy targets for the climate alarmism that pervades America today. Earth’s climate probably is the most complicated non-living system one can study, because it naturally integrates astronomy, chemistry, physics, biology, geology, hydrology, … [Read more...]
