Farenheit 104 (40 degrees C). This is a number everyone should know.
by 8ackgr0und N015e
This graphic needs to be engrained in public awareness. Why? As I said in 2009, global warming could stop photosynthesis in plants we need to survive...

...Since the US is the worlds top exporter of corn (about half the world's export), soya beans (about one third of the world's export) and wheat, damaging the harvest will have a global impact. This follows mere months since similar problems hit crops in Argentina, Paraguay, Uraguay and Brazil. As a result, the price of corn has risen 30% since mid-June and soy prices are the highest they have been in years.
A paper published in Geophysical Research Letters a few years ago, titled, When can we expect extremely high surface temperatures? (warning PDF) offered some sobering projections. Here is one of their graphs. Given the projections shown above (pay attention to the US Midwest) this recent news should come as no surprise. Yet, the current turn of events apparently caught traders and the USDA off guard. The warmer than usual spring meant more planting was done. However, what was a benefit has now become a liability as the heat, coupled with drought, threatens these crops before harvesting.
The combination of low subsoil moisture, which is a reflection of the lack of precipitation that we had during the winter, together with the very hot weather that were seeing right now could spell a pretty disastrous scenario for corn and soyabeans, said Hussein Allidina, head of commodities research at Morgan Stanley.
The seriousness of the problem can be demonstrated by the fact the USDA recently declared less than half of US corn was in good or excellent condition while 22 per cent was in poor condition. Even more concerning is the speed with which this problem developed. Only a few months ago, the USDA was projecting US farmers would produce a record corn crop this year.
The bottom line: The current heatwave threatens to undermine forecasts of record output after the most widespread US corn plantings in 75 years. This is only two years after Russia suspended grain exports because of droughts that were worse than any they had experienced in half a century...

(1,013 posts)Here we've had over a week to swelter, get those heat headaches and nausea-and the garden I carefully water at the sign of wilting leaves...the butternut squash just up and died over night. Just UP and quit.
Here's a lighter side: My first "A" in college was in Astronomy, only took it to learn the constellations. One nice spring time Sunday evening, was sitting out on the deck, and got shaken understates the response. Its always been a source of comfort to see that Big Dipper, good old Ursa Major. But in my six decades had Never seen it upside down, like the dipper was spilling out it contents. Add to that a friend of mine had told me about the "theory" the earth was tilting so many degrees. Stone cold sober, I cried. I spent hours apologizing to the Creator I believe in, and then started on my long list of faults.
Worked at the time in a school cafeteria, so bright and early Monday asked the Science Teacher. He hadn't seen it upside down either. Learned it is a spring and fall event.
Still it changed my perspectives. It will take that for each of us to understand how neglectful we have been and remain disrespectful of the source of Life on this baby blue planet.
You words won't be taken to heart until the famine begins.

(46,192 posts)try to grow something like tomatoes in late spring/early summer something interesting happens...
the plant quickly sprouts in the increasingly hot days of May and June and then after growing just a little, stays green but simply doesn't grow anymore.
too much heat.
also worked with cotton, of all things, one of the most heat tolerant plants.
we simulated increased heat from global warming and were told the results of that was the flowers dropping right off the plants.
you can't just change the weather and expect to do things the way you did before. first, when climate is changing, you don't know whether you will be getting the new pattern one year or the old pattern. second, you don't really have the experience doing things to fit the newer pattern should it actually happen in a given year.
something to consider.

(51,666 posts)after many years of success. It was simply getting too fiercely hot all of a sudden, right when it was pollinating. My last crop produced 2 ears out of a couple dozen plants, whereas I would typically get 3 ears per plant when the weather cooperated.
There were many times I measured 118F on my patio out back near the garden, until the thermometer broke during one epic heat wave.

(5,231 posts)Three things that made me a believer in the biggest way (I'm in Detroit, pretty far north). And, for the record, I've been gardening for thirty years, gaining knowledge along the way. Here are the biggest differences (and this is not the complete list):
1) My rosemary survived for the very first time this last winter. This has never happened. Always a goal (mulching, burlap, planting close to house), yet seemingly impossible based on our snows and hard freezes. Evidently it can survive. However: I didn't protect it at all this past winter; I'd given up. Let it go. It came back.
2) My mint has died immediately once planted the past few springs. That plant is a weed, to me, and will take over anything it can; I've never lost a crop until recently. It just can't handle these current temperatures. I've grown it forever and ever, successfully. I just now realize that I'm not a bad gardener because of this failure.
3) I grow beautiful lavender in DETROIT. Stunning, it is. Have only been able do it in the last six years or so.
As an interesting sidenote: I also have a new weed that I have never seen before (I'm 45) in my gardens, anywhere in this zone. It chokes everything it grows near. Luckily it's shallow rooted, but...I have NEVER seen it before, in 30 years. Where did it come from? I spend half my summer yanking it (don't believe in herbicides).
Based on the above, I understand what you're saying. I have to readjust what I know about growing green things. NOT easy. I'm often at a loss...
CreekDog
(46,192 posts)increased average temperatures may not be seen during the daytime highs, but but higher minimum temperatures. some can be attributed in part to urban heat island effects but many aren't explained by that.
susanna
(5,231 posts)I'm looking over it right now. It explains a lot of weird things...
even across the lake to Muskegan. I had Calla Lilies survive and come back up this year. I always lift them after first freeze, missed a few that had wilted off and couldn't find where the bulbs were...well this year they are up and multiplied just like in the south.
susanna
(5,231 posts)I guess this is what bothers me: I'm an old coot and am used to things going one way, and when they don't, well, that concerns me.
I am trying to keep an open mind, but this is really disturbing on a fundamental level. Things that once were not normal now are...one thing I didn't mention in my post is that I think we might have some kudzu-type vine in Detroit, very close to me (I know kudzu intimately, my family is originally from the south). It's taking over everything. Now, it may be a native Michigan vine with a similar leaf pattern, but I've never seen Michigan-varietal vines grow this fast. In all fairness, the afflicted area is not well-kept, but still, I wonder...

(5,231 posts)I have some really weird insects in my biosphere at the moment. Have no idea where they came from; they are not normal for us.
I had a butterfly explosion with my lilacs this year - never happened before. We were able to get some pictures and figure out the butterfly (I'll look for the name and post it), but it's nothing I've ever seen before.

(19,274 posts)I'm near the Twin Cities, MN, and I planted a pawpaw tree (otherwise known as a Michigan banana) in my yard that's so far survived 3 winters without protection. I've discussed it with master gardeners from the MN Landscape Arboretum, shown them pictures of it, and they tell me they've never heard of anyone overwintering such a tree here. Simply amazing how rapidly things are shifting in the past decade.
susanna
(5,231 posts)It's really only been in the last ten years or so that I've noted the changes, too. I'm that geek-gardener type who keeps a journal. Things I planted, how they grew, rainfall, temps, general info about the growing season; then I document how I bedded them for the winter, etc., etc. It's only been the last decade or so where I have noticed a profound shift. I am obviously seriously concerned or I wouldn't have posted.
BTW, interesting about the pawpaw tree...my grandma use to have one in Alabama. Haven't tasted one in years! Memories, there...strange you're able to grow it this far north.

(912 posts)I had pansies bloom all winter long. They were even blooming under the snow at some points. These were not next to the house or any other building, but surrounding a yard tree. Now they look dead, I can only assume from the heat.
I have been concentrating on low water gardening this year, never been one to water the garden much so have been using all the tricks I can come up with to conserve our well water. (very old hand dug well, not very deep) I was worried about fracking wiping out our water. This topic is very eye opening, I didn't realize blooms can actually fall off a plant from the heat!
Last year was the first time I successfully grew lavender here.
I have been gardening for 40 years, guess I am going to have to do some research and start modifying some of my techniques.
susanna
(5,231 posts)On edit: how many years I've grown lavender (looked back to my garden journals)
I think that's the problem I see. Others, perhaps not so connected to the land/climate they live within, via plants, don't see these changes.
I understand re: the pansies. I grew them a few years ago as a test to see if I was overreacting or imagining things, and they actually overwintered in Michigan. That's not right. Yes, they are hardy, but THAT hardy? No way. Another kicker: parsley, a biennial in hospitable climes (of which Michigan, historically, clearly is not)...yes, it overwintered. The next spring it grew to 3 ft tall. I should clarify that I'm in a weird "warm" zone of Michigan (5b I think) on the Detroit River; it's a little more temperate. I may actually be the proverbial canary in the coal mine about what could happen. (This could also be why I've been able to grow lavender for at least eight years. Yes, eight...I double-checked my records. I originally thought it was six.)
Much of this thread just confirms what I have observed. Everything I have ever known as a gardener is not really "true" anymore. I am having to learn from scratch. And this is dangerous, I think, because knowing how to grow food (or other beneficial plants) really does rely on repeatable, consistent knowledge. If that is being turned upside-down, we are in a very vulnerable position. Modifying our techniques will likely lead to more failures than successes. And then, where will the food be if we fail?
I am probably an alarmist. I suppose I'll have to wait until I can grow citrus or avocado to get anyone to truly take me seriously. But, really - these outliers/anomalies concern me a great deal. They seem to be happening as one-offs (at least as reported) for the moment, but if they become more widespread? As I have a scientific bent of mind, well, I do worry.
dixiegrrrrl
(60,010 posts)one reason I buy growing starts at the feed store in March..
down here, tomatoes don't "set" once evening temps hit 70.
which happens in June now.
The cherry tomaotes are very prolific in hotter weather, but the bigger tomatoes now need part shade
to grow, and stop producing early in our increasing heat.
So I cut the bigger tomatoes down, to about 8 inches of the stalk, keep them in the shade, lightly watered, till evening temps go back down, they grow and set, and I get a fall crop from them.
And also have to spray for blight in the spring..a homemade organic spray.
It has worked well for last 3 years.

The planet Venus is often cited as an example of a runaway greenhouse effect and used to alarm people about the effect of increasing levels of CO2 in the Earth's atmosphere. This material is to put matters in perspective.
This explains everything:
?V/?E = (pV/pV)/(TV/EV) = 90/2.5 = 36

(2,142 posts)I think it's a vinyl post with a metal mailbox (looks like to me anyway). So the weight of the box was able to pull over the vinyl post when it got heated up.
Ironically, my husband is installing a new mailbox (vinyl post/vinyl box) as we speak, so I told him to come take a look at this - his work might be for naught.
joshcryer
(62,277 posts)I should've definitely said vinyl post! I just wonder what has happened to the vinyl fencing that is often touted as really good fencing. With a bit of wind at the temperature point the warping could be incredible.

edit: of course, there could be a pipeline from the Great Lakes to the Grain Belt but yeah, it will take a long time to be built and a Grain Belt drought can kill millions in a year.

(21,088 posts)This threat is converging on us at the same time as the oceans are running out of fish, oil is growing ever more expensive, and the global economy is teetering on the brink of a cascading failure. And what are we doing about it? Burning more coal, of course!
The fossil fuel gluttons have now become the developing nations, largely thanks to the offshoring of our industry causing them to burn ever more coal and natural gas. In a classic example of unintended consequences, offshoring our industry is causing our crops to fail.

(36,418 posts)CO2 has spiked to over 400 ppm in the last decade (and that is not shown on the graph above, which is based in data that is a decade old)(http://www.csmonitor.com/Science/2012/0531/Climate-change-Arctic-passes-400-parts-per-million-milestone), but historically CO2 peaks lag temperature increases by about 800 years, so it is believed not to the cause of temperature swells. Overall, the temperature wave pattern of peaks about every 80,000 years has remained amazingly constant. The article suggests we're due for a cool-off, if the pattern of the last 400,000 years still holds.
