Climate change worries me a lot and I have no idea how to prepare for it in my area. It's getting colder or hotter depending on the year and it's not predictable what it's going to be until after planting.
Just 10 years ago we could count on last frost mid May, first frost mid August and in the time between frequent rain at least once a week. I grew anything in sand soil without ever needing to water. Summer days were 15-25C and nights around 10C. Perfect conditions for roots and tubers, brassicas or peas, all the cool weather crops did great.
In recent years we either got even colder summers with endless rain and temperatures hardly ever climbing above 20C or hotter summers with absolutely no rain and over 30C for months. We already got a lot of 25-30C days in the beginning of May. Winter and then dry summer, spring was missing this year.
I've been watching lupine flowers the past years, which are a good indicator for the weather here. They used to be perfect in time for midsummer decorations. 2018 they were done flowering 3 weeks before midsummer, 2017 they just started flowering 2 weeks after midsummer. 5 weeks difference in growth is a quite worrying range. I'm not sure if any crop can be diverse enough to really thrive in both extremes.
2017 we had frost in june and a lot of flooding. 2018 we had forrest fires, drinking water saving restrictions and wet areas falling dry which had never been dry before. Now in november they just reached normal levels again. Farmers had to drastically reduce their stock in summer already because no grass was growing and feed would not last through winter.
My attempt to deal with these unpredictable extremes is to widen the range of things I grow. Growing cool season crops and warm season crops. The potatoes, peas and cabbage suffered, radish and salad bolted, the broad beans just keeled over and wilted. But I got great tomatoes, peppers, zucchini, eggplants and tomatillos. 2017 was the opposite.
Will see what 2019 brings. I hope not another heatwave

I like my potatoes.
