Real World Global Warming

Every time I hear someone talk about global warming, they discuss the issue in terms that have no real meaning to me. Yes, I understand that the average temperature is going to increase as a result of global warming and that I’ll see weather pattern changes. However, what does it really mean to me? Why should I care? I don’t mean to appear uncaring, but prognostications of impending doom are better served with a dose of reality.

I’ve already discussed one direct result of global warming—the USDA has defined new hardiness zones as described in my Contemplating the Hardiness Zone Changes post. However, even this direct result of global warming doesn’t say much to me. It’s not an indicator that I see every day—something I can point to and say that it’s the result of putting too many of the wrong chemicals into the air.

However, this spring is providing something in the way of a wake up call to me personally. Spring came early this year; very early. Odd spring weather is nothing new to Wisconsin—we get odd weather every year. In fact, it’s the variety and uncertainty of weather that attracts me to Wisconsin. However, no one can remember a spring coming this early. Our spring has also been quite hot and dry. As a result, vegetables that normally do quite well in our garden, such as broccoli, are doing poorly.

In fact, all of our brassicas are doing poorly. I should have planted the brassicas earlier this year to accommodate the warm spring, but I didn’t. Local wisdom says not to plant too much, especially not tender plants, until Mother’s Day, which was simply too late this year. After talking to a number of other people, I find that I’m not the only one who planted too late. Everyone is complaining about how their broccoli has bolted without growing a head. Yes, you can pick the pieces and use them, but what you get is more like a second crop, rather than that perfect first crop in the form of a head.

The weeds, however, are doing marvelously. Rebecca and I can hardly keep up with them. We’re grabbing bushels of weeds from the garden at a time when we’re normally looking at light weeds and are able to mulch to keep them controlled. This year, we’re battling the weeds with vigor and mulching as soon as we get a patch freed from their grasp. However, I’m thinking that the late summer weeds we normally get poking up through the mulch are going to appear by mid-summer this year, long before we’re ready to harvest some of the end of season offerings (assuming they grow at all).

Fortunately, the news isn’t all bad.  We’ve just had the best asparagus season ever. Not only have we had spears vigorously poking their heads above ground, but the spears are thicker and more tender than usual. Rebecca has quite a few meals worth of asparagus already frozen because we can’t even contemplate eating it all without making ourselves sick. So, we’ve learned that asparagus loves exceptionally warm springs, but brassicas  don’t.

We’ve also had a pleasant surprise in the form of cantaloupes. Normally we have a hard time growing them, but we try anyway. The other day I noted that our cantaloupes are already flowering. They also appear quite vigorous this year, so I anticipate getting a lot of a cherished fruit that I often have to buy at the store as a “nicety” instead of picking it from my garden. This change in garden does lend credence to my number one rule of planting a wide variety of items to see what works and what doesn’t in a given year. Next year may very well prove to be the year the brassicas fight back, but this year I’m expecting a lot of broccoli soup.

I had mentioned in a previous post that our trees have also been affected by the spring weather. It turns out that our tree fruit harvest is just about ruined due to the odd weather because our trees simply aren’t used to it. We had thought we might get an exceptionally good berry harvest (the bushes are certainly full enough), but the exceptionally dry weather has already caused the black caps (a kind of raspberry) and the blueberries to fail.  On the other hand, the grapes apparently love our spring and are putting out more than I’ve ever seen them put out.  We can still hope that the blackberry and gooseberry harvests will be good too. The point is to look for the good and bad in the situation (as I described in my Every Year is a Good and a Bad Year post).

When you hear people discuss global warming in the news, it really doesn’t hit home. A degree or two temperature rise doesn’t quite make an impact. Even seeing the loss of ice at the poles doesn’t really hit the nail on the head like seeing your gardening conditions change so significantly that you never imagined they’d be the way they are now. Most scientists now accept global warming as a reality, but they continue to spout facts and figures that most of us can’t begin to relate to. What does global warming mean to you? How have you been affected by it? Let me know at John@JohnMuellerBooks.com.

 

Contemplating the Hardiness Zone Changes

Just in case you weren’t aware of it, the USDA has recently changes the hardiness zones for the United States. The hardiness zones help you understand what will grow in your area. Certain plants require warmer temperatures in order to grow and others require cooler temperatures. For example, if you want peaches, you need to be in a warmer zone. Our area has changed from 4B to 4A, which means that some types of trees that I couldn’t grow in the past will likely grow now. You can see an animation of how the hardiness zones have changed on the Arbor Day Foundation site.

Most people would agree that changes of this sort make global warming undeniable. Of course, it’s a misconception to strictly say that the effect is global warming, which is a misnomer. Yes, the planet has warmed up some, but a more correct assessment is that the weather is going to become increasingly chaotic. The point of this post is not to drag you into a discussion of precisely how global warming will affect the planet, what generalizations we can make about it, whether our scientists can define any long term trends about it, or anything of that sort. I’ll leave the discussion of how much man has contributed toward global warming to those with the credentials to make such statements. The point is that last year I was in Zone 4B and now I’m in Zone 4A. The long term weather changes have finally appeared in the form of new charts from the USDA, which after all, are only predictive and not infallible indicators of anything.

There are some practical considerations in all this and that’s what you need to think about when reading this post. The change in weather patterns means that you need to rethink your garden a bit. Not only do you need to consider the change in heat (the main emphasis of those hardiness zone charts), but also differences in moisture and even the effect on clouds. Little things are going to change as well. For example, have you considered the effect of increased lightning on the nitrogen levels in your soil? If not, you really should think about it. The weird science bandied about by those in the know has practical implications for those of us who raise food to eat after all.

Even if you aren’t into gardening at a very deep level, the changes in the hardiness zone chart has one practical implication that no one can escape. The literature on the back of those seed packets you buy from the store is going to be incorrect for this year as a minimum. The changes from the USDA came out after the seed packets were already printed. When everything else is said and done, the main reason for my post today is to help you understand that you can’t believe the seed package—at least, you can’t believe it this year. By next year the seed companies will have recovered and the documentation on your seed packets will be useful again.

Springtime is approaching. If you live anywhere near my area of the country, it seems as if we’re going to have an early spring indeed. I don’t normally need to trim the trees in the orchard until the end of March. This year I’ll trim my trees on March 1st, a lot earlier than normal and even then, I might be trimming a bit late. A few people in our area have already seen budding trees. So, if you’re used to waiting until April or May before you get out very much, it may be a good idea to take a walk around your property now to see if there are any changes that you need to know about.

Global warming is a reality. The effects it will have on your garden and orchard are also a reality. Just what those effects are and precisely what has caused them are still being debated by those in the know, but if you’re a gardener, you need to be aware that the garden you had last year may not work this year.
