The 16th International Conference on Climate Change (ICCC16), organized by the Heartland Institute and held April 8\u20139, 2026, in Washington, DC, featured a recurring theme: \u201cWhat Is The Proof?\u201d \u2014 specifically, what empirical evidence supports claims of a worsening \u201cclimate crisis,\u201d including increases in extreme weather events.<\/p>\n\n\n\n

A detailed recap by Francis Menton (Manhattan Contrarian) on April 10, 2026, highlights Nobel Laureate physicist John Clauser\u2019s presentation on extreme weather as particularly noteworthy. Clauser, co-winner of the 2022 Nobel Prize in Physics for work on quantum entanglement, has become an outspoken climate skeptic who scrutinizes the underlying data and claims.<\/p>\n\n\n\n

By Francis Menton<\/a><\/p>\n\n\n\n

I spent the past couple of days attending the International Conference on Climate Change, put on by the Heartland Institute in Washington<\/a>. There was a good deal of material that will be of interest to readers.<\/p>\n\n\n\n

A major issue addressed by multiple presenters goes under the heading \u201cWhat is the proof?\u201d, and in particular what is the proof that there is some kind of climate \u201ccrisis\u201d coming our way. You will not be surprised to learn that for most every claim of the climate cabal, the proof is lacking.<\/p>\n\n\n\n

The most interesting presentation on this subject came from John Clauser. For those who haven\u2019t heard of him, Clauser was one of the co-winners of the Nobel Prize in physics in 2022<\/a>. The specific subject of Clauser\u2019s prize was something called \u201cquantum entanglement,\u201d which seems to be only peripherally related to climate change. However, Clauser\u2019s presentation made it look like since winning the prize he has spent much of his time studying the literature on climate change, and particularly studying the data that are cited to support claims of impending climate crisis. Over that period, he has become a very outspoken climate skeptic. He is clearly a very smart guy, with a sharp critical eye. Also, he has taken a specific approach, which is to examine the data looking for gaps, alterations or manipulations that might render the data insufficient to support the claims being made. (See also, my series on The Greatest Scientific Fraud Of All Time.<\/a>) I think that this approach is the essence of the scientific method, but sadly it is mostly absent from the climate \u201cscience\u201d cult. Finally, Clauser has specifically focused on certain flaws or manipulations of the data that can be seen easily and understood by a layman without any need for specific scientific expertise.<\/p>\n\n\n\n

Clauser titled his talk \u201cGlobal warming, climate change, and scientific consensus have not been proven. There is no proven climate crisis.\u201d The talk was accompanied by a Power Point deck of some 124 slides, which were way too numerous and detailed for him to cover everything or for an audience member to take thorough notes. However, I managed to get my hands on a copy of the deck. (Clauser\u2019s full talk is available on the Heartland website<\/a>, and I also understand that the deck will be available on the website within a few days.)<\/p>\n\n\n\n

Today I will start with the part of Clauser\u2019s presentation relating to the issue of what are called \u201cextreme weather events\u201d \u2014 e.g., floods, droughts, hurricanes, tornadoes, heat waves, and the like. For this sub-topic, Clauser began with a 2012 article from Physics Today by Jane Lubchenco and Thomas Karl, titled \u201cPredicting and managing extreme weather events.\u201d<\/a> (L&K) At the time of the article, which was during the presidency of Barack Obama, Lubchenco was the Administrator of NOAA, and Karl was Director of NOAA\u2019s National Climatic Data Center and Chair of the US Global Change Research Program. In other words, these were the people then in charge of collecting the U.S. weather data, including data on extreme weather events, on behalf of the government. As Clauser noted in his talk, if there were any people who would have access to the very best data to support a claim of increasing extreme weather, it would be these two.<\/p>\n\n\n\n

The thesis of the L&K piece is that extreme weather events in the U.S. have been increasing, and can be expected to increase further as the climate warms. Here\u2019s the introductory paragraph:<\/p>\n\n\n\n

Earth\u2019s climate is warming, and destructive weather is growing more prevalent. Coping with the changes will require collaborative science, forward-thinking policy, and an informed public.<\/em><\/p>\n\n\n\n

Besides making their own statement to that effect, L&K also quote multiple similar statements from the IPCC:<\/p>\n\n\n\n

\u201cIt is very likely that heat waves will increase in length, frequency, and\/or intensity over most land areas. . . . It is likely that the average maximum wind speed of tropical cyclones will increase throughout the coming century. . . . It is likely that the frequency of heavy precipitation or the proportion of total rainfall from heavy falls will increase in the 21st century over many areas of the globe.\u201d<\/em><\/p>\n\n\n\n

So what is the proof?<\/p>\n\n\n\n

L&K present a series of charts that they assert establish the proposition that extreme weather events in the U.S. have \u201cgrown steadily over the past several decades.\u201d<\/em> To measure the level of these extreme weather events within the U.S., L&K come up with something they call the \u201cUS Climate Extremes Index.\u201d They describe the Index as having been calculated based on \u201cthe area percentage of the country experiencing extreme monthly temperature, drought severity, soil water surplus, days with and without precipitation, land-falling hurricane activity, and one-day heavy precipitation events in any given year.\u201d <\/em>However, beyond that description, there is nothing in the way of a technical description and backup of how the charts have been constructed quantitatively. A footnote with a link to a prior Karl article on the subject, presumably containing these details, returns a message \u201cnot found.\u201d<\/p>\n\n\n\n

My first comment on this \u201cClimate Extremes Index\u201d is that it is an extremely dubious metric, obviously subject to very easy manipulation. For example, who has decided how much land area was covered by a particular \u201cland-falling hurricane\u201d? Is it just the land area where the wind speeds exceeded 75 mph, or is it the entire area overswept by the hurricane storm system over its full life span of possibly several days, mostly with far lower windspeeds? Hidden decisions like that could easily be used to manipulate an index like this to produce a desired result.<\/p>\n\n\n\n

However, Clauser does not go there, and instead he just takes the values of the index as presented by L&K and asks whether they actually increased over the period covered. Here is Figure 2a from L&K, showing the values of their U.S. Climate Extremes Index over the period 1910 to 2011:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

If you look at that and don\u2019t see any particular increase, let alone some dramatic surge in recent years, you won\u2019t be the only one.<\/p>\n\n\n\n

And it gets worse. Clauser took the values of the Index shown on the bar graph, and re-plotted them as dots on a scatter diagram. Then he did another plot where he reversed the order of the observations, so that the newest observations were on the left and the older on the right. In other words, the two plots are mirror images of each other. Here they are:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The years on the x-axis both indicate that they run from oldest to newest, but Clauser states that he has left it that way intentionally to challenge the observer to figure out which chart is plotted backwards. Here is Clauser\u2019s text from his slide 9:<\/p>\n\n\n\n

The two graphs are identical, except that one is plotted left-to-right reversed, i.e. backwards, with time increasing to the left. (If you look carefully, you will see that they are mirror images of each other.) I assert that if you can\u2019t tell which one of these graphs is correctly plotted and which one is time-backwards, then Lubchenco and Karl\u2019s claimed recent increase in extreme weather-event frequency is <\/em>not <\/em>obviously indicated by their data. One of these graphs is claimed by Lubchenko and Karl to forecast an impending climate apocalypse! Are you really confidently willing to bet trillions of dollars that you can tell which one makes that forecast?<\/em>\u00a0<\/p>\n\n\n\n

Clauser concluded this segment of his presentation by calling L&K\u2019s conclusion \u201cfraudulent pseudoscience.\u201d It is an odd sort of fraudulent pseudoscience \u2014 baldly asserting that a collection of data supports a conclusion that the data obviously do not support, and expecting everyone to just nod along. It\u2019s hard to believe that with all the data at their disposal, this is the best that L&K could come up with to prove the case of increasing extreme weather events. But that\u2019s a lot of how \u201cclimate science\u201d works.<\/p>\n\n\n\n
