Waiting for ripening

The garden is producing, however not ripening,is it the weather? global warming? can't be the later, we haven't had many great days this summer. The nectarines are changing colour but are still as hard as nails, the peaches are green and as small as the nectarines, the strawberries are there, but don't ripen at the same time as to have them as dessert, and last but not least the zucchini plant has a lot of leaf, no flowers so no produce. What a year, thank goodness for the supermarket and the fruit stall across the road.
