Hello UKAC~I have heard the same from many different folks in many differing locations about the Globe(including myself)thing is,whatever the cause may be of a seemingly brighter Sun and the apparent ability to feel like you are being burned/pinched in relatively cool Temps. a lot easier than had been noticed before has to be of a Terrestrial Origin as the Sun isn't actually becoming any brighter as you can see from this graph [link to lasp.colorado.edu] .
