[additional comments] Many scientists disagree that fossil fuels are a principal cause of global warming and believe, instead, that fossil fuels are a very minor contributor to global warming. Most scientists believe that the principal contributors to global warming are from natural effects.
On 25 April 2015, I attended a Climate Change Lecture at New Mexico State University presented by Dr Gregg Garfin of the University of Arizona, who is Co-Convening Lead Author of the Southwest States Chapter of the National Climate Assessment. The lecture and the graphics for Dr. Garfin’s presentation are available on line.

This post is in four sections: before Convening Lead Author Dr Gregg Garfin arrived at NMSU, the lecture itself, the question I asked during the “Q and A” session and concluding thoughts. There is also an addendum.

No one can really predict the future, but I would like to speculate on it a bit and maybe unravel a few promising threads from the tapestry of time and
see what one or two future worlds might look like.
Demographic threads, a discussion of future growth, will Capitalism survive?, Artificial Intelligence (AI) in the future, the future of work, emerging medical processes, the future of poverty and the influence of global trade are a few of the hot spots of future development. And what might the future climate turn out to be?
Demographics and the Future
In the past we have briefly discussed global demographic trends and I will only focus on them as they might influence the future of growth, poverty, work and automation issues. Continue reading “The Future of Everything”

UPDATE(2/23/18):The previous version of this post had improper latitude bounds for the HadCRUT4 Tsfc data. I’ve rerun the results… the conclusions remain the same. I have also added proof that ENSO is accompanied by its own radiative forcing, a controversial claim, which allows it to cause multi-decadal climate change. In simple terms, this is clear evidence the climate system can cause its own, natural, internally-generated climate changes. This is partly what has caused recent warming, and the climate modelling community has assumed it was all human-caused.Continue reading “A 1D Model Of Global Temperature Changes, 1880-2017”
The year 2017 featured incredibly intense, damaging wildfires in California. First the Wine Country fires of October, and later, in December, the massive Thomas Fire, each destroyed hundreds of homes. The latter, in many of the affluent suburbs and enclaves northwest of Los Angeles and Hollywood. The Thomas Fire is the largest in modern California history with over 1000 structures destroyed.
California’s Governor Jerry Brown blamed human-caused CO2-fueled
global warming for this conflagration during a visit to Ventura County on 9 December, saying the drought conditions were the “new normal.” To quote the governor, “There have (historically) been very long droughts in California and we are getting some of those returning very bad, and we’re going to get them returning more often.”
But, Governor Brown is just wrong about this, as an examination of some meteorological and climate data shows:
