UAH Global Temperature Update for July, 2023: +0.64 deg. C August 2nd, 2023 New Record High Temperatures and a Weird Month

July 2023 was an unusual month, with sudden warmth and a few record or near-record high temperatures.

Since the satellite record began in 1979, July 2023 was:

warmest July on record (global average) warmest absolute temperature (since July is climatologically the warmest month) tied with March 2016 for the 2nd warmest monthly anomaly (departure from normal for any month) warmest Southern Hemisphere land anomaly warmest July for tropical land (by a wide margin, +1.03 deg. C vs. +0.44 deg. C in 2017) These results suggest something peculiar is going on. It’s too early for the developing El Nino in the Pacific to have much effect on the tropospheric temperature record. The Hunga Tonga sub-surface ocean volcano eruption and its “unprecedented” production of extra stratospheric water vapor could be to blame. There might be other record high temperatures regionally in the satellite data, but I don’t have time right now to investigate that.

Now, back to our regularly scheduled programming…

The Version 6 global average lower tropospheric temperature (LT) anomaly for July 2023 was +0.64 deg. C departure from the 1991-2020 mean. This is well above the June 2023 anomaly of +0.38 deg. C.

There's a 1,000 acre forest fire eight miles from us (the "Ridge Fire"). If only the Republicans had gotten behind stopping global warming, this wouldn't have happened. It's all so needless. Earth was so perfect before man discovered fossil fuels...actually, before God created Adam. It's all God's fault for making Adam intelligent and having dominion over the earth.

Enough to make it rain 40 days and 40 nights?

Moisture in the stratosphere doesn't cause rain. A year ago or so I calculated that total amount of moisture in the stratosphere from the volcano was enough to cover greater Atlanta in a couple of inches of water. Trivial compared to what's in the troposphere, except that because it is in the stratosphere it causes warming in the troposphere.

Genesis 7:11:11 In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.

You may be on to something there.

I can hardly breath ..its so hot.

Let’s just be perfect for the rest of this day.

“Obama’s war on coal started”

Although, that was a short war. obama spoke.. Both sides pretended to take a side for a day and a half... and everyone gave in to “obama”.

Did you go with the 58,000 swimming pool estimate? For this to have been climatologically of consequence, it seemed trivial. it must have been more than that.

[ProtectOurFreedom]

The first estimate I saw was in the hundred trillion GALLON range. They must have figured nobody would get that, so next came the swimming pool estimate.

I didn’t run any numbers, but at first blush that seemed like a trivially small amount of water compared to what is in the atmosphere.

[palmer]

Don't remember, so I'll have to redo it. NASA says 58,000 swimming pools time 88,000 cubic feet per pool or 5104000000 cubic feet. Atlanta is 134.0 square miles or 3735705600 square feet. Divide the cubic feet by the square feet and get 1.3 feet of water.

Something is off. Maybe I used more than Atlanta itself. Even so, it's not a lot of water compared to the troposphere.

[palmer]

100 trillion gallons is 150 million swimming pools (660000 gallons per pool). I don't remember where I got my numbers a year ago, but I did it to point out that the heavy rains a year ago could not be caused by that water even if it all magically migrated to one spot.

[sopo]

Thanks for calling attention to meteorology 101 , which I didn’t take with difference of troposphere, stratosphere

[ProtectOurFreedom]

Spread that 1.3 feet of water in Atlanta across the entire globe. You probably get less than micron.

The 2022 Hunga Tonga–Hunga Haʻapai eruption was the largest volcanic eruption since the 1991 eruption of Mount Pinatubo, and the most powerful eruption since the 1883 eruption of Krakatoa. The dust from the latter created a brief climate “winter”, and colored sunsets around the world for four years.

Because of a ginormous amount of heat released into the ocean, it might have caused or at least contributed to the current enlarged El Nino. The vast column of water reached through the stratosphere and into the mesosphere.

Originally, the volcano rose 2,000m from the sea floor and its caldera was 150m below sea level by 4,000m at its widest point.
