Yesterday was 1st March and the official beginning of autumn in Australia. Coincidentally, I saw this link from the Bureau of Meteorology. This is what 1C of warming looks like. Are you prepared for 3-4C increase in temperatures? That is what we look like reaching this century if the government continues its current level of inaction. Not a great future for our children and grandchildren.
Meanwhile, I do not actually need the Bureau of Meteorology to tell me about the longer summers. It is clearly evident in my own backyard.
This photo taken today is of our liquidamber tree. It always loses all of its leaves each year but this has become progressively later each year. There is not even the slightest colouration of the leaves yet.
On the other hand, I am trying to make the most of the longer summer. I planted a second crop of corn at the beginning of February. It takes 3 months to mature and I want to see if we can extend our summer growing season until the end of April.
I am also growing zucchini late in the season.
There definitely needs to be a change in mindset with regard to sowing and growing times if we are to make the most of the climate changes.
It is definitely much too warm to consider cool weather crops yet. The forecast maximum temperatures for our area (400m elevation) are 27 – 29C for the next week and this pattern is likely to continue until the end of the month.
While hothouses allow tropical plants to be grown in cooler climates, I am wondering whether there will come a time when cooler weather crops such as cauliflower, broccoli and cabbage become impossible to grow in our location. It seems that celery is no longer possible to grow here as the seeds need cool soil to germinate.
Food security is just one very real and present threat from climate change.
