Guest Post by Willis Eschenbach [See Update at end] I kept going back and looking at the graphic from my previous post on radiation and temperature. It kept niggling at me. It shows the change in surface temperature compared to the contemporaneous change in how much energy the surface is absorbing. Here’s that graphic again:…
Guest Post by Willis Eschenbach [SEE UPDATE AT THE END] Due to the recent posts by Lord Monkton and Nick Stokes, I’ve been thinking about the relationship between radiation and temperature. So I turned to the CERES dataset. Here is a scatterplot of the monthly global average surface temperature versus the monthly global average downwelling…
Guest Post by Willis Eschenbach Grrrrr … gotta pull this one. The effect I found was due to the interaction of the El Nino with the seasons. Once I removed that, very different results. When I’m wrong, I’m wrong, no getting around that. Ah, well. I’ll return to this subject of correlations with Nino/Nina, it’s…
Guest Post by Willis Eschenbach I took another ramble through the Tropical Rainfall Measurement Mission (TRMM) satellite-measured rainfall data. Figure 1 shows a Pacific-centered and an Atlantic-centered view of the average rainfall from the end of 1997 to the start of 2015 as measured by the TRMM satellite. There’s lots of interesting stuff in those…
Guest Post by Willis Eschenbach People often say that we’re heading into the unknown with regards to CO2 and the planet. They say we can’t know, for example, what a 2°C warming will do because we can’t do the experiment. This is seen as important because for unknown reasons, people have battened on to “2°C”…
Guest Post by Willis Eschenbach In a previous thread here on WUWT, a commenter said that the sunspot-related variations in solar output were shown by Labitzke et al. to affect the stratospheric temperature over the North Pole, viz: Karin Labitzke cracked that nut. She was the first one to find a correlation between not one…
Guest Post by Willis Eschenbach Over in the Tweeterverse, I said I wasn’t a denier, and I challenged folks to point out what they think I deny. Brandon R. Gates took up the challenge by claiming that I denied that sea level rise is accelerating. I replied: Brandon, IF such acceleration exists it is meaninglessly…
Guest Post by Willis Eschenbach In the comments of my last post entitled “Spot The Volcano, 1815 Edition” someone mentioned that Thomas Jefferson had commented on what is often called the “Year Without A Summer”. This was the summer of the year 1816, one year after the eruption of Mt. Tambora in Indonesia, which occurred…
Guest Post by Willis Eschenbach It’s been a while since I played “Spot The Volcano”. The premise of the game is that the decrease in temperatures from volcanic eruptions is nowhere near as large as people claim. So I ask people to see if they can identify when a volcano erupted based on the temperature…
Guest Post by Willis Eschenbach. I came across an interesting 2014 paper called “The energy balance over land and oceans: an assessment based on direct observations and CMIP5 climate models“. In it, they make a number of comparisons between observational data and 43 climate models regarding the large-scale energy flows of the planet. Here’s a typical…
