If corn likes it cool then we can plant it earlier,harvest it , plant beans during the summer heat and plant another corn crop in the fall. There wont be any winter so we can plant all year long.
Global warming could rob the U.S. economy of $1.4 billion a year in lost corn production alone, a national environmental group estimated in a report released Thursday.
First the can not prove that global warming is currently hapening and if it is, what it is actually doing. That is why they “estimate” the amount ofcost.Just typical agenda driven scare tactics.
“”Corn likes it cool, but global warming is raising temperatures across the nation,” said report author Timothy Telleen-Lawton in a news release. “Hotter fields will mean lower yields for corn, and eventually, the rest of agriculture.””
Utter BS. Warmer equals more crops. Also, it is going to be 29F in Ohio on Easter morning. Where is this “raising temperatures across the nation” occuring? IT ISN’T.
I am planting buttery popcorn. We figure we’ll eat it right off the stalk as the heat pops it for us. We’ve got a lot of salt stored up too.
Corn grows just fine in Louisiana, which gets pretty darned hot. And I suspect the 3% decrease ("if" it happens at all, which I doubt) will be more than made up by a longer growing season in the Dakotas and Canada.
I’ll just file this under “Global Whining”.
Who, but the MSM takes these "reports" seriously. We need to start issuing reports debunking the "reports".
Could, might, maybe, estimated, modeling, I suppose anything is possible, just GW is highly improbable given the science.
This from Iowa State University:
“Common corn varieties will not grow below 49o F (9.5o C), grow fastest at 93o F (34o C), will not grow above 115o F (46o C), and die at 118o F (48o C), with growth rate responding to temperature in an “S-shaped” curve between 49o F (9.5o C) and 93o F (34o C) (Bonner and Galston, 1952).
Above 93o F (34o C), the growth rate begins to drop off again. If the temperature rises above 110o F (43.3o C), it drops off very rapidly. That would be true heat stress, a temperature of 110-115o F (43-46o C). Between 50o and 93o F, the crop can grow very well.
Fig. 1.11 Relative growth rate as effected by temperature.
The S-shaped line represents the way a crop develops according to temperature. A straight line might represent the mean or average response, a way to evaluate it simply using growing degree days. The straight line is an approximation. If the temperatures are below 60o F, the crop development in actuality would be considerably less than indicated by the straight line. If the temperature is 80o or 86o F, the actual development of the crop may be greater than the straight line would indicate.
Fig. 1.12 Relative growth rate as approximated by the growing degree day.
The straight line approximation to crop growth is known as a growing degree day model. The growing degree day model begins at 50o F (10o C) and goes up to 86o F (30o C) as a straight line. The growth rate of the crop goes from 0 to 1, from nothing to maximum, as temperature increases from 50o to 86o F. After 86o F, we assume that increased temperature does not have any additional positive effect, but not necessarily a negative effect. The growth rate levels off at that point.
The growing degree day is the expression of this line. If the temperature is below 50o F, there is no growth. If the daily temperature averages 55o F (12o C), some increment of growth would be evident during the 24-hour period. This growth is calculated according to a formula where the maximum temperature and the minimum temperature are averaged less some base temperature. The formula for the growing degree day is the maximum temperature plus the minimum temperature averaged, minus 50:
Equation 1.4
If the daytime high temperature is 70o F and the overnight temperature, 50o F (typical for late May), and you average those and subtract 50, the answer is 10 GDD during the 24-hour period.
If the daytime temperature were 70o F, there were probably 10 growing degree days during the 24-hour period. During a 24-hour period the value can range from 0 to as much as 36, which is the maximum value for growing degree days. Crops cannot develop any faster than that, so that is arbitrarily set as the top value. Seldom would a value of 36 be reached.
There are rules for computing growing degree days:
(1) That 86o F is the highest temperature considered. Why 86o F? The crop has its ideal growth at 93o F. Why not 93o F? Seldom do we have ideal conditions for aeration, for fertility, and for water availability to the crop. As the temperatures get higher, the crop’s demand for water may become higher. At a higher demand for water, the crop may come under water stress. In the Midwest, on the average, water stress begins at about 86o F. So we do not consider 93o F optimum unless everything is perfect. We consider 86o F the optimum temperature for crop growth. So, if the maximum temperature is greater than or equal to 86o F, it is called 86o F.
If the temperature in the day were observed at 90o F, for the purpose of calculating growing degree days, you would say the high temperature was 86o F. If it went up to 95o F, you would say the high temperature was 86o F because the temperature for the developmental growing degree day is not allowed to exceed 86o F.”
I was born in Illinois in July. My Boston raised 21 year old mother complained about the heat, and her inlaws replied “its good corn growing weather”!
I was just walking in a corn field not five miles from the bay here in Mobile, Alabama...the corn is about four inches high and the temperature is about 80 degrees and will be in the 90's before the corn matures.
These people know absolutely NOTHING about corn. It takes HEAT to mature corn. A cool summer results in corn maturing at a date later than is typical. Extreme heat at polination time is not good, but once the corn is polinated, heat is a good thing, as long as there is enough moisture.
And CO2 enhances corn development. Should produce better yields, if I understand it correctly.
“Global warming could rob the U.S.”
These people ARE NOT scientists.
Even if you gave the “global warming” prediction the credit it does NOT deserve, in terms of predicted annual average global temperature, there is NOTHING that can predict that that “average” will be expressed ONLY as higher temperatures everywhere, and much in climate science that says some places will experience colder temperatures and much that says exactly which places will be warmer is not possible to predict.
So, even if you gave the “global warming” prediction the credit it does NOT deserve, in terms of predicted annual average global temperature, that higher average cannot, with any scientific accuracy, be applied to any one particular area, not Iowa or anywhere else.
An average is an average, and ocean currents and air currents and cloud cover and other factors DYNAMICALLY redistribute “temperature” and DO NOT spread it evenly.
Predictions about precise affects in precise locations are no better than looking in a crystal ball.
***”Corn likes it cool, but global warming is raising temperatures across the nation,” said report author Timothy Telleen-Lawton in a news release. “Hotter fields will mean lower yields for corn, and eventually, the rest of agriculture.” ****
And back around 1977 Progressive Farmer magazine said the corn belt would be moving south because of coming ICE AGE!
——Corn likes it cool——
These people think they can say anything... They obviously haven’t been in Iowa in August.
Corn is a warm-season crop that requires high temperatures for optimum germination and rapid growth
http://www.ncsu.edu/sustainable/profiles/botcorn.html
The ideal temperature for corn growth is cooler than many may think: 75 to 86 degrees. With a plentiful supply of moisture, corn will tolerate temperatures in the mid 90s.
So what. 1.4 billion per year? Isn’t that like 10 minutes of government spending in a $3.5+ Trillion budget?
