Hiding The Decline At Berkeley Earth

Zeke from Berkeley Earth shows the whole earth burning up since 1960, particularly the Arctic – which has warmed “by more than 4C.

Zeke Hausfather on Twitter: “The world as a whole has warmed by 0.9C just since 1960, with some parts of the Arctic warming by more than 4C. Here is a map of warming between January 1960 and August 2019: https://t.co/npJrw5TIeb” / Twitter

He shows Antarctic warming, which NASA wrote in 2004 had cooled significantly.

Satellites show no warming in Antarctica, since 2004 – so we can see that the Berkeley earth trends for Antarctica are incorrect.

There was almost no sea ice around Antarctica in January 1976

Now let’s look at why Zeke chose 1960 for a start date. There was a unanimous consensus Earth was cooling.

January 30, 1961 – NYTimes

Earth had cooled sharply prior to Zeke’s start date.

Scientists were talking about a new ice age.

Next let’s look at the US, which is one of the few places on Earth with good historical coverage.


Zeke starts his map near the end of a 30 year cooling trend.

The US has been cooling over the past century.

Now let’s look at the Arctic data which is being hidden. There was 9C Arctic warming by 1939, and sea ice was disappearing

Zeke starts his trend map right at the low point for Arctic sea ice.

There was 11C Arctic winter warming by 1954, and scientists blamed it on CO2 – right before temperatures plummeted into the ice age scare.

Arctic warming and cooling cycles correlate with an ocean circulation pattern – the AMO – not CO2.

Zeke has good reason to hide the Arctic data before 1960.

Climate scientists have wanted to hide the warmth of the 1940’s – and that is exactly what they are doing.

Zeke has now completely erased it. He blames it on National Geographic.

So the next question is – why is National Geographic  hiding the  warm pre-1960 data from their November 1976 graph?

    Not sure if I’m missing something, but did Seth (who is a real moron) remark about the Arctic, or Antarctic getting colder? I ask because you show the data for Antarctica, but you’d written about “Arctic.”

  2. Phil. says:

    One of your cited articles included the following:
    “In the Barents Sea area where, dur-
    ing earlier observations, only small
    patches became free from ice, large
    spaces of open water now occur at
    frequent intervals.”

    Nowadays the Barents Sea is ice free for several months, as it is now.

    • Gator says:

      Yes Phail, ice melts when the world warms. Let me educate you, it’s time someone does.

      The Little Ice Age ended sometime around 1850, it began roughly 550 years earlier, and it was likely the coldest period in the past 10,000 years. As intelligent humans would imagine, ice advanced during this cold period and conversely, when the Earth began to warm out of the LIA the ice once again retreated. We are still warming out of the LIA Phail, so of course the ice that built up is still melting. This would explain why the ice in the Barents Sea was more extensive when we were closer to the end of the LIA than it is now. Very simple logic.

      Even so, there is currently more ice in the Arctic than the average of the past 9000 years. You see Phail, ice melts when the temperature raises above 32F. In fact it melts even if the temperature raises to 40F, and then goes back down to 33F. Phail, the fact that ice continues to melt does not mean that it is getting warmer, it just means the temperature has remained higher than it was during the LIA.

      Do you hate poor brown people Phail, or are you just incredibly ignorant?

    Zeke is an energy systems analyst and environmental economist with a strong interest in conservation and efficiency. He was previously the chief scientist at C3, an energy management and efficiency company. He also cofounded Efficiency 2.0, a behavior-based energy efficiency company.

    Zeke has zero academic background in climate science. This explains why he bought into the “oceans are warming faster” disaster of a paper (Quantification of ocean heat uptake from changes in atmospheric O2 and CO2 composition), and foolishly blabbed about it for the past year. Zeke makes his living off of doomer predictions, the worse the prediction, the more money he makes.

    Follow the money, not the idiot grantologist.

    “Little known data from the state of the art U.S. Climate Reference Network (which never seems to make it into NOAA’s monthly “state of the climate” reports) show that for the past nine months, six of them were below normal,

    The data, taken directly from NOAA’s national climate data page, shows not only that much of 2019 was below average, but that the US Temperature average is actually cooler now for 2019 than we were in 2005, when the dataset started.

    The U.S. Climate Reference Network (USCRN) was established to give the most accurate temperature readings compared to the old Cooperative Observer Network (COOP) which suffers from urban encroachment, siting problems, and a multitude of human induced inhomgeneities such as station moves, incomplete data, closed stations, and runway condition stations at airports that were never designed to report climate data”

    The Berkeley Earth temperature record for New Zealand has been homogenised with bull effluent.

    They are climate apocalypse industry manure spreaders fertilizing the chicanery.

  6. Gamecock says:

    That global map, “Warming since 1960,” is amusing. Probably 90% of the area shown had NO DATA in 1960. Double ought zero. Not til the advent of satellite measurement, 1979, did we have data for all the earth. Showing warming in central Africa, for example, is a joke, as well as many other areas.

    5.5 million square miles of Arctic. Where were the thermometers in 1960?

  7. kadalino damarlane says:

    Great article! The truth needs to come out!

  8. Bruce of Newcastle says:

    Zeke has at last discovered the ~60 year cycle has he?
    That is amazingly perceptive.
    Why, maybe he’ll notice that big warm thing in the sky next.

  9. Zachary Uram says:

    Zeke is making money off climate alarmism.

  10. John of Cloverdale, WA, Australia says:

    Tony/Bruce of Newcastle, as for southeastern Australia, I have looked at the long temperature records (over 100 years from 1880 or 1900) of the monthly temperature anomaly graphs on the Berkeley Earth website. In the examples below, BE have changed the raw temperature trend from negative, or insignificant, to a strong positive warming trend after their breakpoint/homogenized adjustments (BE figures below in degrees C per century):
    Bourke (from -0.49 to +0.24); Benalla (from -0.60 to +0.79); Echuca (from -0.34 to +0.60); Hay (from +0.18 to +0.59); Omeo (from -0.40 to +0.62), and Deniliquin (from -0.10 to +0.41).

    Also, It is telling that Zeke starts his global temperature anomaly map at 1960 (?cherry picking) which is when most of the SE Australian station mean annual temperatures are at their historical (from 1880/1900 to present) near minimum, corresponding to the negative phase minimum of the IPO ocean cycle.

    • Bruce of Newcastle says:

      John – Yes, that’s what I meant about the ~60 year cycle, which is quite obvious and evident in the AMO, IPO/PDO, ENSO, rainfall data and a few other datasets – not least HadCRUT 3. You can see from the graph that the IPCC’s century 1906-2005 is from the very bottom of the previous cycle to the top of the current cycle. That’s half of the warming last century – which is an artefact of the choice of dates. It’s the same scam as starting a graph in 1960.

  11. Was Zeke among the scientist-impersonators pretending to be shocked that ozone varies with sunlight and Antarctic volcanoes? The 1/9 of humanity in the Southern Hemisphere certainly had nothing to do with ozone shortages never registered over the populous Northern polar cap. But if the ban on low-pressure freon they engineered in 1987 is making refrigeration equipment unreliable, what better scapegoat than misanthropic global warming to invent as an explanation for why an aging population feels hotter?
