The cloud albedo effect on surface temperatures is stronger than I once thought it would be. Yesterday’s letter provided the kind of evidence that leads to a conclusion of great strength in the selected examole, especially well-confirmed on the map … Continue reading →

Today’s Weather Maps are absolutely loaded with information. Each map contains an amazing amount of detail, every bit of which is obtained from instrument readings of things that are happening in the real world. Whenever a detail on one of … Continue reading →

Today’s letter will be devoted to image comparisons, with a special focus on “Geopot” maps showing high-altitude air pressure configurations. I saved these in the archives a year ago in mid-July, so we do year-to-year comparisons for both hemispheres as … Continue reading →

“Laying the foundations for a new science of climate change.”  This is what it says in the upper right corner of every letter, and this is what Carl’s Climate Letters is all about.  The letters did not start out that way. … Continue reading →

What is the average lifetime of precipitable water (PW) molecules after they enter one of the upper level wind systems? This is possibly the most critical question of all relevant to the analysis initiated in Friday’s letter. Every molecule should … Continue reading →

How is Earth’s greenhouse energy amplified by precipitable water (PW) contents in the upper atmosphere? This is a good question, one that, if true, deserves a better answer than any I have offered so far in these letters. I want … Continue reading →

Part 2 of Carl’s theory describes the mechanism that facilitates the poleward movement of precipitable water (PW) in the upper level of the atmosphere. All PW enters this zone in the form of steadily flowing streams of water vapor that … Continue reading →

A current heat wave in western Asia can be compared with the one that just happened in the Pacific Northwest. The territory I have in mind appears on this map as a distinct feature just east of the Caspian Sea, … Continue reading →

Carl’s theory is now reasonably complete as far as major claims and conclusions are concerned. I can already think about some details that need to be added and also expect the theory to need corrections or adjustments here and there. … Continue reading →

What is meant by a “heat dome?”  We see this term being used more and more often when explanations are needed for extreme heating events, like the one that recently struck the Pacific Northwest.  There are some variations in the … Continue reading →
