I'm in Canada and spring is starting earlier and earlier every year but we will still get blasts of (what used to be normal for that time of year) frost/snow/freezing rain. The problem is with the warm weather, fruit trees will start to bud early and when the cold comes at night it kills all the buds and that's it, no fruit. Last year apple orchards all over lost their crops to this. The instability is what's going to cause chaos in the world.

Spring seems like it comes later and later to my eye. When I started farming in Canada we would have the ground prepped in mid-April and were really to start planting May 1st.

In the last 5-10 years we struggle to even get on the ground until mid-May. This year is no exception. May 13th already and we have only half of a field planted so far.

Have you heard about the damage done to grape and stone fruit crops in BC? It has been happening consistently enough that I expect some vineyards not to exist in the next decade.

Even where I am it’s considered a temperate climate and a friend’s grape crops were almost totally destroyed from a snap freeze in late February. He said it wasn’t that uncommon for the freezes to happen when he started, but what changed is how early the vines start budding, like you mentioned.

Late-starting crops can bypass this problem, but my understanding is that they often need irrigation because they grow into the tail of summer. That’s not really viable here either, as water’s gradually diminishing from our extended drought.

I'm not out west so I haven't heard about it happening there too.

BC wine industry in some areas purportedly had a crop loss of something like 90% by some estimates. With a 3 year turn around to re-establish the plants, and a very smoke tainted 2021, their industry is certainly in a trouble spot. Let's see if they have enough reserves to sell to get them past this disaster.

not just smoke tainted, a small bit of Kelowna (the heart of BC wine country) straight up burned down last year

the whole area is actually surprisingly dry in terms of rain due to being in the rain shadow of the mountain. the lakes nearby make it tolerable, but even a small shift in climate patterns will turn the area into a near-desert.
