I ran into this article about the UK Met Office. The office has been big on global warming and their seasonal forecasts have been on the warm side. Note the article says that they stopped doing seasonal forecasts after both a summer and a winter forecast turned out to be too warm. Scroll down to the part below the picture of the woman working at the computer. It says that scientists and the Met Office and elsewhere are beginning to understand the solar cycle and that a minimum of sunspots means colder weather for Britain and Europe. In June, the American Astronomical Society released a press release on three separate lines of research that came to the identical conclusion that the sun was “shutting down” as they called it…moving into a period of minimal activity (sunspots, solar wind, magnetism). Dr. Hill wrote: “That would affect everything from space exploration to Earth’s climate.” Here’s more details. The first graphic is from NOAA and shows the anemic sunspot count, which trended up a little in the first 3 months of this year, but has now headed down again. The second is a comparison of the current solar minimum to the Dalton Minimum of the early 1800s. Looks pretty similar to me. NASA has written about the lowest sunspot count in a century, the lowest value for the Solar Wind, the loss of solar magnetism and the drop in solar irradiance. Here’s a record of temperature. Note that the cool period associated with the Dalton Minimum. I’ll also add that the cool period coincided with the Tambora Volcano and the following “year without a summer”. Volcanic effects usually last for a shorter period of time (months to several years) as opposed to 30 years of general cooling and note that the cooling began before the volcanic activity. I’ve had several people write and ask me to put something up about the changes on the sun. The sun’s behavior certainly bears watching. AND – thousands have fled a new erupting volcano in Indonesia. It last erupted in 1991…same year as Pinatubo. UPDATE: Here’s an interesting article about temperatures increasing at Seattle recently. I’ve always mentioned that the general movement of weather stations to airports from earlier not-airport locations is likely responsible for a small uptick in temperatures. This would be most apparent on sunny days and on calm nights where the planes and cars would stir the air and the heat given off by nearby buildings might have an influence.
Will the Earth Cool?
