The key premise of the claim that there is a climate crisis is that CO2 in the atmosphere traps heat in the form of outgoing long wave radiation(OLR). Radiation, which is energy carried by electromagnetic waves vibrating at different wavelengths, is a means of heat...

If  you have some interest and a little time, but don’t want to get too “into the weeds”, watch The Climate Movie for a terrific, entertaining overview. https://www.youtube.com/watch?v=p4vSMj4R5Rg If you want to know what three world-class physicists think about...

The American government and European governments are forcing obedience to the idea that human-caused emissions of carbon dioxide will lead to catastrophic global warming and must be eliminated.  This idea is entirely and unequivocally false. CO2  is not now and never...

Joe Biden, the permanent bureaucracy, the Democratic Party, their cheerleaders in the mainstream media, and the global elites – the types who each year flock to Davos for a meeting of the World Economic Forum – tell us that climate change is an existential threat to...

1. Climate change activists want you to believe that the rise in atmospheric CO2 from fossil fuel burning is causing a dangerous warming of the Earth’s surface. 2. The idea is not supported by the evidence. 3. Since 1850, before humans began to burn fossil fuels for...

I am inaugurating a series of posts on climate change for people who want to know what the key facts are, and what scientists think is a true picture of how the climate system works. “True” as defined here means that the description provided will be shown to be valid...

Overview  … climate change is a permanent feature of planet Earth; any human impact that might be occurring is probably too small to discern against a background of natural variability (Singer, p. 118. There remain many uncertainties about how the climate system...

There ae two reasons. First, the models don’t match what has actually happened, and second, the Summary for Policymakers (SPM) misrepresents what the science says as reported in the IPCC’s AR5. The theoretical models used to predict future warming are not consistent...

The foundation for government climate policy worldwide is The United Nations Framework Convention on Climate Change (FCCC) , an international environmental treaty addressing climate change, negotiated, and signed by 154 states at the United Nations (UN). Its policy...

The first thing to note about the temperature of the Earth’s surface is that it has been variable ever since there was an atmosphere, and these variations have had no significant relationship to  the concentration of CO2 in the atmosphere.  Historic data show CO2...

The short answer is not much, certainly not enough for anyone to worry about.  Furthermore, the temperature change observed is nothing out of the ordinary. In the past 120 years since 1900, there has been a 1.2 degree Celsius increase in global temperature (Lindzen,...

No. The best evidence on [whether there is an acceleration in sea level rise] is tide gauge data from stations in tectonically stable areas with more than eighty years of uninterrupted recording. . Such data show a steady linear sea level rise of about 18 cm [about 7...

If you really want to annoy a climate alarmist cultist, you can assert that global cooling is what we should expect. Nobody knows what triggers little ice ages (LIAs), but some experts expect that a LIA may be coming our way. Why? They cite a strong correlation with a...

Subsequent to the election of Biden as president, the mainstream media have been full of stories heralding the robust flowering of green energy and an accelerating decline in the use of hydrocarbons, mainly oil and gas. I instinctively distrust anything the mainstream...

The National Aeronautics and Space Administration (NASA) recently released a climate change study reporting that the last decade was the warmest in modern times (since 1880 when reliable record keeping began). The National Oceanic and Atmospheric Administration (NOAA)...
