Katharine Blames Floods On CO2

July 10, 2017

By Paul Homewood



Another gem from Katharine in that interview with Yale 360:

There have been an enormous amount of flooding events in the Midwest and Northeast.


Well, what do the experts at the USGS have to say on the matter?

In 2012, they published a paper, “Has the magnitude of floods across the USA changed with global CO 2 levels?”.

This is the Abstract:

Statistical relationships between annual floods at 200 long-term (85-127 years of record) streamgauges in the coterminous United States and the global mean carbon dioxide concentration (GMCO2) record are explored. The streamgauge locations are limited to those with little or no regulation or urban development. The coterminous US is divided into four large regions and stationary bootstrapping is used to evaluate if the patterns of these statistical associations are significantly different from what would be expected under the null hypothesis that flood magnitudes are independent of GMCO2. In none of the four regions defined in this study is there strong statistical evidence for flood magnitudes increasing with increasing GMCO2. One region, the southwest, showed a statistically significant negative relationship between GMCO2 and flood magnitudes. The statistical methods applied compensate both for the inter-site correlation of flood magnitudes and the shorter-term (up to a few decades) serial correlation of floods.


The USGS press release also stated:

Climate changes that could influence flood magnitudes include shifts in the intensity and tracks of various types of storms and changes in the type of precipitation (rain versus snow). The conditions on the landscape when large storms arrive can also change (for example, smaller snowpacks, less soil moisture and less frozen soil). All of these can influence the size of floods. Of course, human activities within the watershed can also have a major influence in the size of floods. These include urbanization, building of dams and levees, and shifts in vegetation types and drainage of soils and wetlands. At the present time, we see much larger changes in flooding from these causes than we can see from greenhouse forcing.


There have always been floods, but Katharine now believes they are caused by CO2.

    Increased [CO2] ramps up the water cycle as a response of the water cycle to increased surface temperature as one part of the planetary PID control system.

    Facts and the truth really don’t matter to these Alarmists, and I suspect some believe what they say is true regardless of the evidence – because it ought to be true somehow.

    The fact that the media simply accept whatever they say is appalling too.

    I used to think people like her were just uttering outright lies. Now I’m inclined to think they really believe the nonsense they spout and their brains are automatically screening out any contrary information as “denialist lies” no matter where it comes from. They’ve brainwashed themselves 😉

      Note this was published in The Guardian. I was brought up in a “Guardian-reader” household – a daily fix of propaganda to make sure any contrary ideas offer no cognitive dissonance to threaten the readers’ stability. I know how they think. Moved on since, but it took me a long time. So has The Guardian; if unconvinced by socialist politics, you’ve just got to be in favour of saving the planet, havn’t you ? Hence their obsession with the “meme”.

    “About 12,000 years ago, the valleys of western Montana lay beneath a lake nearly 2,000 feet deep. Glacial Lake Missoula formed as the Cordilleran Ice Sheet dammed the Clark Fork River just as it entered Idaho. The rising water behind the glacial dam weakened it until water burst through in a catastrophic flood that raced across Idaho, Oregon, and Washington toward the Pacific Ocean. Thundering waves and chunks of ice tore away soils and mountainsides, deposited giant ripple marks, created the scablands of eastern Washington and carved the Columbia River Gorge. Over the course of centuries, Glacial Lake Missoula filled and emptied in repeated cycles, leaving its story embedded in the land.” (from glaciallakemissoula,org).

    This was not a one-time event, but occurred as many as 80 times. How, would Ms. Katherine explain this?

      Probably caused by excessive hot air from her and people like her….

    Do you think Katharine has been breathing in too much CO2? I’m told that can affect the brain.

      It presumes the existence of a brain.

    Her thesis was titled “Talking Absolute Boll*cks to Gullible Idiots”.

    None of that matters. What matters is the execrable corruption of the English language. “There HAVE been AN enormous …….”
    The sad uneducated, or at least poorly educated lass thinks the verb is qualified by the plurality of events when in fact it is by the SINGLE “enormous amount”.
    And she has a job as a writer.
    Who cares about the planet, since we is all doomed in any case to suffer of ‘er lingo?
    Lord, take me now.

      I would have said “an enormous number of events.” Amount and number have been confused.
      A large amount of nonsense is talked by an increasing number of professionals

    Answer me this Katharine, if CO2 is supposed to ‘trap the heat’ how come the effects of all those El Niños are so short lived?
    If that’s the best CO2 can do well I can live with that.

    As the old adage goes, you’d have to be highly educated to be this stupid. Katharine Hayhoe is just another example of the utter worthlessness of an “education” in the modern social sciences.
