A Day Without Global Warming – Would You Rise For It?
David Middleton’s “Not the Zero They’re Looking for” Guest
One of my LinkedIn connections posted a very interesting map yesterday:
Using a baseline of 1979-2000, Saturday’s global temperature abnormality was…
The map is from the University of Maine’s ClimateReanalyzer.org. Today’s “climate” is only 0.1°C higher than “normal” (normal is in quotes for a reason 😉)…
ClimateReanalyzer.org is quite an interesting site and seems to be a useful addition to our climate data “toolkit”. Here’s an example of the kind of “fun” you can have with this:
Based on Schwalm et al., 2020CO accumulation2 emissions are tracking the bad sci-fi scenario RCP8.5, while temperatures are tracking below the “stable scenario” RCP4.5…
The RCP 4.5 scenario is the steady-state scenario, which means that the radiated forcing is stable at 4.5 W/m2 before 2100 using a range of technologies and strategies to reduce greenhouse gas emissions.
When did they find out that they overestimated climate sensitivity to CO2?
Curiously, UAH 6.0’s most recent monthly temperature anomaly over its 1991-2020 base period is also just above the Dean Wormer line at +0.03°C.
Global temperatures leaving the average in January have fallen from December by essentially zero, at +0.03°C (+0.05°F). The equatorial cooling associated with the presence of La Niña continues, and the tropics are now significantly below the 30-year average at -0.24°C (-0.43°F). ). As is often noted in these reports, the maximum cooling effect of La Niñas usually occurs between February and May. The latest information on this La Niña event can be found here.

What’s really funny is that despite nearly 50 years of “catastrophic” climate change emergency situation crisis, it is now 1.0°C warmer than it was during the “Ice Age”…
Even if anthropogenic CO2 emissions are indeed the cause of all warming since 1975…
A little warmer than “The Ice Age Cometh” should be considered a good thing… Right?
Of course, the modeled “natural” elements and myths are strictly limited to what the modeler understands about “natural” elements and myths.
PS: If I had to tell you when I was being sarcastic, it would take all the fun out of the irony.
