In an otherwise fine article at WattsUpwithThat.com, Ari Halperin writes: For some time, the subject [of the residence time of anthropogenic carbon dioxide in the atmosphere] was surrounded by confusion, created by sloppy definitions and evasive statements in IPCC assessment reports. There was a mix-up between the residence time of a CO2 molecule in the atmosphere and the rate of change of the surplus CO2 concentration. The residence time (~5 years) is of little interest, except as an … [Read more...]

On Climate and Economic Policy, What do the World’s Poor Need?
Recently the Cornwall Alliance sent to over 2,900 faculty members of Christian colleges and universities around the country an email asking them to consider endorsing our An Open Letter on Climate Change to the People, their Local Representatives, the State Legislatures and Governors, the Congress, and the President of the United States of America. The email had the name of Dr. Roy Spencer, Cornwall Alliance Senior Fellow and Principal Research Scientist in Climatology at the University of … [Read more...]
Preventing Climate Change does Not Help the Poor, It Dooms Them!
Many climate scientists argue that we need to mitigate global warming because otherwise it will be the poor who will be hurt the most. Apparently these scientists do not understand their own models. Projections from climate models are based on the rates of poverty reduction, with the highest (‘worst’) temperature projections resulting when the poorest people in the world increase their incomes from $246 (measured in constant 1990 USD) to $49,000 per year (approximately equal to U.S. GDP per … [Read more...]
How NOAA Lies with Global Warming Statistics
A subscriber to Cornwall Alliance’s e-newsletter recently wrote asking us if we have replies to the various graphs at “Climate Change: Global Temperature,” on the National Oceanic and Atmospheric Administration’s (NOAA) Climate.gov web page. Oh my goodness the misrepresentations of facts in those graphs are awful! Preparing refutations/analyses of all the graphs there would be a very long and complex project for which I simply cannot take time. But let’s take this one—probably the most … [Read more...]
#UNSelfie Template for #GivingTuesday
Click here to download the #UNSelfie Template. Giving Tuesday is fast approaching, and I know we are all very busy between now and December 1st. Many of us have family coming into town, or we are traveling to family events, and there is still grocery shopping to do, and a Thanksgiving meal to prepare. To make life easier, we have prepared an #UNSelfie template for you to use to publicly announce your support of the Cornwall Alliance on Giving Tuesday. Simply write in why you are supporting the … [Read more...]
Does the “Precautionary Principle” Favor Fighting “Climate Change”?
Proponents of efforts to mitigate climate change often appeal to the “Precautionary Principle”—Principle #15 of the Rio Declaration in 1992: “In order to protect the environment, the precautionary approach shall be widely applied by States according to their capabilities … [W]here there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.” In light of that, we … [Read more...]
Climate Scientists are Steadily Reducing Estimates of Warming from CO2
Among climate scientists specializing in climate sensitivity there is a clear trend toward lower and lower estimates of it, as the chart below shows. Why? Because the empirical measurements of GAT have fallen so much lower than model-generated predictions. In the chart, the dates are dates of publication (bottom axis) of peer-reviewed studies making estimates of climate sensitivity measured in degrees Celsius (left axis). ECS denotes “equilibrium climate sensitivity,” warming predicted in … [Read more...]
Kicking off the Christmas Giving Season with Giving Tuesday
This year the Cornwall Alliance has decided to kick off our Christmas giving season by participating in the global day of giving known as Giving Tuesday! WHAT IS #GIVINGTUESDAY? We have a day for giving thanks. We have two for getting deals. Now, we have #GivingTuesday, a global day dedicated to giving back. On Tuesday, December 1, 2015, charities, families, businesses, community centers, and students around the world will come together for one common purpose: to celebrate generosity and to … [Read more...]
Low Climate Sensitivity Makes Fighting Global Warming Unwise
To achieve the IPCC’s 3˚ “best estimate” of warming from doubled CO2 since the Industrial Revolution by the end of this century, GAT would have to rise another 2.593˚ in the remaining 63.5 years, a rate of 0.41˚ per decade, which is 3.7 times as fast as the observed rate so far. To achieve the 2˚ lower bound claimed for over 20 years, GAT would have to rise two-and-a-quarter times as fast as the observed rate. Even to reach the 1.5˚ the IPCC now claims is the lower bound, GAT would have to rise … [Read more...]
What’s Wrong with Science Behind Global Warmings Fears?
Bad science is the foundation of fears of dangerous, manmade global warming and therefore of any policy recommended to reduce it. If you’re like many Americans, you find that position surprising, because you’ve heard that many national academies of science, the United Nations Intergovernmental Panel on Climate Change (IPCC), and an alleged overwhelming consensus of the world’s scientists say the opposite. So why should you judge that the skeptics are right and all those others are … [Read more...]
