Didn’t Katharine Study History At School?
By Paul Homewood
It appears that Katharine Hayhoe still does not get it. When the Director of the Texas Tech’s Climate Science Centre was interviewed on local TV, she had this to say:
"Trees are flowering earlier in the year than they used to, here in Lubbock and across the entire northern hemisphere," according to Hayhoe. "Lubbock’s climate for plants feel just like Austin’s did 20 years ago. That’s how fast things are changing and we can see them all around us."
Well, let’s see what the facts tell us.
The nearest USHCN station to Lubbock is Crosbyton, a mere 33 miles away. The annual mean temperature record is below.
There has certainly been a jump in temperatures in the last 20 years or so, but all they have done is return to the level commonly seen between the mid 1920’s and mid 1950’s. Since 2007, the annual average temperature has been 60.73C, compared with 60.65C between 1934 and 1954. Meanwhile the warmest year on record is still 1927.
Katharine talks specifically about “trees flowering earlier”, so can we identify any seasonal changes? Lubbock lies in Division 1, in Texas, so let’s look at the winter temperatures from NCDC for there.
Once more, we see that there is absolutely nothing unusual about recent temperatures. The colder interlude in the 1960’s and 70’s is again apparent, but winter temperatures prior to that period were pretty similar to now.
To understand why temperatures have gone up in the last couple of decades, you need to understand why they went down in the first place. And to understand that, you also need to understand the great ocean cycles, the PDO and AMO.
Joe D’Aleo shows the relationship between these ocean cycles and US temperatures.

As with so much of our climate, US and Texas temperatures are driven by ocean cycles. A proper climate scientist would, of course, know this, and would also be fully aware of the long term data and trends.
But, as we already know, Katharine is not really a proper climate scientist.

NOT A LOT OF PEOPLE KNOW THAT 
This is happening in the UK and all over the world.
Simply because weather patterns have recently returned to those seen in the past, “climate scientists” are jumping to the conclusion that it is due to “climate change”, caused by “global warming”, because it fits their theories, i.e. “confirmation bias”.
How long has science known about the pdo & amo? Thanks.
According to Wiki, the AMO was identified in 1994.

The PDO was named in 1997.

I would guess that much was known about both many years before.
“a proper climate scientist” is a self-anointed one, since the academic field doesn’t really exist, and would require mastery of at least 10 and up to 100 actual sciences to practice if it did.
Actually a proper climate scientist as defined by Harrabin cannot be independent but rather is someone who studies at Big Climate Institutions (e.g. Phil Jones) which are mostly dependent on climatepanic being hyped for their funding
– He finds that not many of those people “deny” Climate change ..even though CO2 sores while temp stays about the same.
soars
I have always said that belief in “climate change” is dependent on people having very poor memories. The less one remembers about the last few decades, the easier it is to convince them “suddenly everything is very new and bad”. If only we could improve memory, perhaps the truth would become apparent.
