“These findings here are unlikely to be popular with the establishment. The political obstacles are massive,” he said.Dr Evans says historic global warming has been down to solar activity – a process called “albedo modulation” – the waxing and waning of reflected radiation from the Sun.Between 2017 and 2021 he estimates a cooling of about 0.3C before the mini ice age in the 2030s.
“I know students from every background and across every major. They don’t feel comfortable around cops. They just don’t. It makes safe spaces feel not so safe,” one unidentified student remarked, with another telling the Post that it’s “weird” seeing cops on campus.
In fact, Sunday’s cold broke the record low high of 44 degrees, set in 1910, Channel 2 meteorologist Brian Monahan said.
41 now at #atl.. record low high for today is 44 set in 1910 @wsbtv

Last time we felt temperatures this cold was around St. Patrick’s day in March, when it was 37 degrees, Monahan said.
Parts of North Georgia woke up to see snow flakes falling and metro Atlanta wind chill made it feel like temperatures in the 20s.
Snow flurries in far north Ga. this morning! Would you welcome this winter weather?! @BMonahanWSB is tracking our cold temps, next on Ch. 2. pic.twitter.com/0QYz3jmDBw

It’s cloudy, windy and cold, Monahan said, and it’s going to stay that way Sunday.
“More sun is coming, but the cold isn’t going anywhere,” he said. “It is going to stay windy, too.”
Communications Interoperability Training with Amateur Radio Community Set
Elements of the US Department of Defense (DOD) will conduct a “communications interoperability” training exercise November 4-6, once again simulating a “very bad day” scenario. Amateur Radio and MARS organizations will take part.
“This exercise will begin with a national massive coronal mass ejection event which will impact the national power grid as well as all forms of traditional communication, including landline telephone, cellphone, satellite, and Internet connectivity,” Army MARS Program Manager Paul English, WD8DBY, explained in an announcement.
During the exercise, a designated DOD Headquarters entity will request county-by-county status reports for the 3,143 US counties and county equivalents, in order to gain situational awareness and to determine the extent of impact of the scenario. Army and Air Force MARS organizations will work in conjunction with the Amateur Radio community, primarily on the 60-meter interoperability channels as well as on HF NVIS frequencies and local VHF and UHF, non-Internet linked Amateur Radio repeaters.
Record-Melting Fall Heat Wave Bakes Southern California
By Bob Henson
It’s not every Oct. 23 or 24 that millions of Americans are swathed in temperatures above 100°F. This week has done just that, bringing some of the toastiest weather ever observed in the U.S. during late October, and more pre-Halloween heat is on the way.
By far the most scorching weather has been in Southern California, although it’s also been exceptionally mild this month in settings as far-flung as Michigan, Florida and New England.
 The current exceptionally long minimum of solar activity has led to the suggestion that the Sun might experience a new grand minimum in the next decades, a prolonged period of low activity similar to the Maunder minimum in the late 17th century. The Maunder minimum is connected to the Little Ice Age, a time of markedly lower temperatures, in particular in the Northern hemisphere. Here we use a coupled climate model to explore the effect of a 21st-century grand minimum on future global temperatures, finding a moderate temperature offset of no more than −0.3°C in the year 2100 relative to a scenario with solar activity similar to recent decades. This temperature decrease is much smaller than the warming expected from anthropogenic greenhouse gas emissions by the end of the century.
