EN: Dr. Roy Spencer serves thoughtfully on the Cornwall Alliance Board. What follows is a response to Gavin Schmidt’s blog post at RealClimate.org entitled Spencer’s Shenanigans in which he takes issue with my claims in Global Warming: Observations vs. Climate Models. As I read through his criticism, he seems to be trying too hard to refute my claims while using weak (and even non-existent) evidence.To summarize my claims regarding the science of global warming:In Gavin’s post, he makes the … [Read more...]
‘Demographic Warming’: Humans Increasingly Choose to Live Where It’s Warmer
This is the second of a series of articles in which Cornwall Alliance board member and senior fellow Dr. Roy W. Spencer explains the importance of distinguishing urban heat island effect from global temperature increase and of recognizing that by choosing to live in warmer regions of the world and in cities rather than in cooler and rural or wilderness areas, people demonstrate their preference for warmer temperatures. You can find the first article here, and the second here. and the third … [Read more...]
Examples from our New UAH Urban Heat Island Dataset
This is the second of a series of articles in which Cornwall Alliance board member and senior fellow Dr. Roy W. Spencer explains the importance of distinguishing urban heat island effect from global temperature increase and of recognizing that by choosing to live in warmer regions of the world and in cities rather than in cooler and rural or wilderness areas, people demonstrate their preference for warmer temperatures.

A New Global Urban Heat Island Dataset: Global Grids of the Urban Heat Island Effect on Air Temperature, 1800-2023
This is the second of a series of articles in which Cornwall Alliance board member and senior fellow Dr. Roy W. Spencer explains the importance of distinguishing urban heat island effect from global temperature increase and of recognizing that by choosing to live in warmer regions of the world and in cities rather than in cooler and rural or wilderness areas, people demonstrate their preference for warmer temperatures. You can find the first article here. As a follow-on to our paper submitted on … [Read more...]
New paper submission: Urban heat island effects in U.S. summer temperatures, 1880-2015
This is the first of a series of articles in which Cornwall Alliance board member and senior fellow Dr. Roy W. Spencer explains the importance of distinguishing urban heat island effect from global temperature increase and of recognizing that by choosing to live in warmer regions of the world and in cities rather than in cooler and rural or wilderness areas, people demonstrate their preference for warmer temperatures.After years of dabbling in this issue, John Christy and I have finally … [Read more...]
SITYS: Climate Models Do Not Conserve Mass or Energy
One of the most fundamental requirements of any physics-based model of climate change is that it must conserve mass and energy. This is partly why I (along with Danny Braswell and John Christy) have been using simple 1-dimensional climate models that have simplified calculations and where conservation is not a problem.Changes in the global energy budget associated with increasing atmospheric CO2 are small, roughly 1% of the average radiative energy fluxes in and out of the climate system. So, … [Read more...]
UAH Global Temperature Update for July, 2023: +0.64 deg. C
New Record High Temperatures and a Weird MonthJuly 2023 was an unusual month, with sudden warmth and a few record or near-record high temperatures.Image: Creative Commons under UnsplashSince the satellite record began in 1979, July 2023 was:These results suggest something peculiar is going on. It’s too early for the developing El Nino in the Pacific to have much effect on the tropospheric temperature record. The Hunga Tonga sub-surface ocean volcano eruption and its “unprecedented” production of … [Read more...]
UAH Global Temperature Update for June, 2023: +0.38 deg. C
The Version 6 global average lower tropospheric temperature (LT) anomaly for June 2023 was +0.38 deg. C departure from the 1991-2020 mean. This is statistically unchanged from the May 2023 anomaly of +0.37 deg. C.The linear warming trend since January, 1979 remains at +0.13 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).Various regional LT departures from the 30-year (1991-2020) average for the last 18 months … [Read more...]
The Urban Heat Island Effect in GHCN Station Temperatures: Urban Locations Show Large Spurious Warming Effects
It has been a while since I have posted progress on our DOE-funded research into the Urban Heat Island (UHI) effect in the GHCN station temperatures used to monitor land-based global warming. It should be remembered that everything I post on this subject is (as is usually the case) a work in progress.What I am addressing is the existence of localized long-term warming associated with population increases which are over and above the large-scale warming due to humanity’s greenhouse gas emissions … [Read more...]
Americans Increasingly Choose a Warmer Life
We hear that a new El Nino forming in the Pacific Ocean is likely to push global-average temperatures to new record highs in 2023.Setting aside the fact that we have no idea if current temperatures are warmer than during the Medieval Warm Period of ~1,000 years ago, I have to ask…So what?Doing something about global warming depends a lot on how much we are asked to pay to fix it. If it was cheap and practical, we would have already transitioned to renewable energy sources.It also depends … [Read more...]
