Other than stay at home in a nice warm house?
If you're just of the green and its hard or frozen ground then maybe just use the putter, more predictable than chipping if the ground is frozen.
I use my putting stroke fro chipping anyway which makes it easier and if the greens are rock hard i dont have to think too much if i swap the wedge/iron for the putter.
That's where Gankas lost me - all of the rotation and then the push off to the front side when the club is parallel on the downswing. It seems very "swing in the barrel with level hips" up to a point. I do like his "no pull down" of the arms and pressure on the lead arm, taller at address leading to better posture through the ball, and how a flying elbow can lead to a natural shallowing. Good patterns for some people.
Playing tomorrow with a forecast of 0 overnight, maybe 1 celsius by the time we start - it's the minor course, so it will be open despite the frost, and we will play.
The same happened last month and it destroyed my round because normally the short game is where I make up my shots, and I couldn't chip in these conditions.
The two problems, which compound one another, seem to be :
a) soft,delicate chips are very difficult because grass contact can stop the club almost completely
b) firmer, more lofted contact is risky because the ball may just bounce off the green instead of gripping
I couldn't seem to the find a way to get around these problems last time I played, any ideas?
Watched an interview with the guy from Snell and realised my above post is incorrect - balls that have been kept warm overnight will stay warm for a few hours, and they shouldn't be warmed above 100f.
So that decides it, I'll keep a sleeve of balls somewhere warm in my house overnight before a morning cold game, and not worry about it.
