This article will be short, I promise. It will be much shorter than Bob Tisdale's latest protest (archived here). Bob's posted a bunch of charts that show just how hot February was. The contrast between Bob's first lot of charts and what he wrote is quite extraordinary. (Bob then fudged the next lot of charts to make the warming go away, which is typical behaviour from him.) Bob thinks that people are silly to react to this chart of global mean surface temperature - and this is only since 1997!

Or this next chart of Northern Hemisphere monthly temperature. (Remember the shock when the anomaly broke through one degree above the 1951-1980 average? Last month it was almost at 2 C above it.)

Bob Tisdale isn't worried. No sirree. He calls it "Alarmism Cranked Up to Absurd Level". In his denial he laughs at scientists who voice their concern that it's getting more and more urgent to address climate change.
As you know, Bob Tisdale removes 30 months (2 1/2 years) of data to try to persuade his fans of imaginary differences between modeled and observed temperature. He's taken up disinformation as an immoral pursuit in his semi-retirement.
No, Bob - it's not just El Nino
There's one more thing - Bob still thinks that all the warming is caused by ENSO. Bob doesn't believe Tamino when he removed the effects of solar, volcanoes and ENSO from the trend. He thinks Tamino left a bit out. I don't think so. Bob wrote:
Apparently his model needs some work, because after supposedly removing the effects of El Niños it still shows an uptick caused by the 2015/16 El Niño.
Bob was referring to this chart in Tamino's "Surprise, but not shock" article, which has been adjusted to remove the effects of ENSO events, and volcanic and solar forcings. Even so, February was still very hot:

Heed the scientists, don't take any notice of denial from disinformers like Bob Tisdale
There's an article at The Conversation by Steve Sherwood and Stefan Rahmstorf. I suggest read both that article and the one by Tamino to get a better sense of what all this means.
From the WUWT comments
I didn't add any comments when I first posted this article. They are mostly forgettable. However I've just seen a new one added, which is a very long rant from Arn, who is questioning the credentials of retired meteorologist from the UK Met Office, ToneB. The entire comment is nonsensical, and I've highlighted some bits that are particularly Dunning-Kruger-ish:

You’ve been saying so many goofy things it’s unlikely you graduated high school.
Is there any particular job you ever worked in measuring anything for money?
Any particular field you were employed using scientifically certifiable measurement mechanisms where if you did your job wrong you were fired?...
...The way we real scientists know you are a fake one is you say you believed in all that disjoint, thermodynamic law violating trash.
Real scientists utilize and conform their thought processes to the laws of mathematics and physics....
...You’ve never been involved in anything like that Toneb, and the way it’s so easy to tell, is that you think climatology is actually a field of science. Climatology is a word made up by people who were trying to separate the grants they applied for, from weather grants.
Climate is weather,
Weather is climate.
You don’t need some particularly unusual experience or training to study the three phases of matter involved in climate. There’s the solid phase earth, there’s the plasma phase sun, there’s the liquid phase green house gas water, and the gas phase general atmospheric mix.
The fact you’re going on about how ”climatology” is some high and mighty art reveals that you’re actually an environmentalist not even a science student.
