They said it was climate change

Norway figured this out years ago

Is 3.225% man made, of .04% of C02 in the atmosphere, SCARY for you CC?

These guys might be on to something:
WORLD'S GREATEST PROBLEM.
Agricultural Science.
Amazing Experiments.
It is said that some amazing ex-
periments that have been carried out
in Germany may lead to a revolution
in agriculture, and solve the world's
greatest problem—that of food. It has
long been obvious to all thinking
people that the only hope for the
world lies in the development of agri-
cultural science, so that two blades of
wheat or maize or rice may be made
to grow where only one grew before.
The problem is a pressing one, and
in his attempt to solve it Dr. Riedel,
of Essen, a German scientist, seems to
have obtained marvellous results.
As we all know, the green leaves
of plants take carbon dioxide from
the atmosphere, and in some way
produce starch and sugar to feed the
plant. Now, the ordinary atmosphere
contains only about one twenty-fifth
of 1 per cent. of it bulk of carbon
dioxide, or four parts in every ten
thousand parts of air; and twenty
million cubic yards of air; and
twenty million cubic yards of air are
needed to furnish the carbon for a
tree whose wood weighs ten thou-
sand pounds.
Knowing all this, Dr. Riedel con-
ceived the idea of speeding up the
growth of plants by giving them extra
supplies of carbon dioxide.
Living and working in a great
manufacturing district, Dr. Riedel re-
alised that vast volumes of carbon
dioxide, harmful to man and beast,
were being thrown into the atmos-
phere every hour, and lost. He
calculated that an ironworks dealing
with 4,000 tons of coke a day in its
blast furnaces produces about 250
million cubic feet of carbon dioxide.
There were, therefore, immense sup-
plies available.
Dr. Riedel set to work, designed a
process for arresting the gas, and
took out patents. Then he put his
great idea into practice. He set
aside three greenhouses, in each of
which the same kind of plants were
grown under similar conditions, ex-
cept that in one house extra supplies
of carbon dioxide were to be sup-
plied from blast furnaces. The test
began in June.
The results were such as to amaze
even the scientist. A few days after
starting the test the leaves of a cas-
tor oil plant in the greenhouse sup-
plied with gas measured a yard
across, while the largest leaf of a
similar plant in the other greenhouse
was about 18 inches. The height in-
creased correspondingly. Tomatoes
in the greenhouse supplied with gas
weighed 175 per cent. more than in
the other houses, and cucumbers show-
ed increase of 70 per cent.
At the same time experiments were
made in the open air, gas being sup-
plied to a plot of land through open-
ings in cement pipes arranged all
around. The gassed plot showed an
increase of 150 per cent. in spinach,
180 per cent. in potatoes, and 100 per
cent. in parsley.
Quite recently the experiment has
been tried of gassing a barren and
hitherto uncultivated piece of land
not very far from Berlin and re-
sults have been equally remarkable.
From these results there seems to
be no doubt that fertilising the air
with carbon dioxide is a more effi-
cient and cheaper way of increasing
the crops than treating the ground
with manures. In greenhouses in
winter the same coke furnace that
supplies the heat will provide, the ad-
ditional carbon dioxide.
Dr. Riedel believes that before long
ironworks will be systematically sup-
plying carbon dioxide to farmers.

How amazing that we knew all this in 1922, and over 100 years later, have completely lost the knowledge about how plants use CO2.

The last statement In bold) was especially prophetic.

So how much extra growth from increased levels of CO2 are you getting in the southern Alberta drought with higher evapotranspiration rates? None because your biggest limiting factor is a shortage of water!

That is certainly an interesting question Chuck. We had roughly 9.5 inches of rain and grew barley that yielded from 100 bushels per acre up to 120 depending on the variety. Certainly zero till has helped. Has the increased C02 made a difference? Certainly possible.

[chuckChuck]

There is evidence that the benefits of CO2 will be offset by higher temperatures and hotter summers especially in some crops like Canola.

Look at Crop insurance payouts in the last 3 years. They have gone through the roof! Do you think CO2 is going make up for all the weather losses? Not a chance!

I keep seeing headlines about the hottest year ever.
I also keep seeing headlines about the world harvesting the biggest crop ever in history.
And prices seem to reflect that reality.
yet for all these years, the warmunists have been warning that global warming was going to decimate crop yields and lead to starvation.
How do you square that circle?

[chuckChuck]

"warmunists"

Climate change is impacting yields but weather is still variable. So yes there will be good years and bad years.

Ask you buddies in south, some who have had several years of drought and a severe water shortage whether they think a warmer dryer climate will solve their problems?

The most important point Chuck2 is that the carbon tax or covering good farm land with Chinese solar panels isn’t going to make it rain. Making life more expensive for Canadians won’t change the weather. Building no new roads like Stephen Guilbeault wants won’t lower the average temperature. This is an ideological battle combined with fear mongering to allow the increase in size and reach of government. China and India will build enough coal fired electrical plants by 2030 that what Canada does won’t matter, that is the reality.

“Warmunists”, certainly made my Sunday AB5.

[chuckChuck]

Hamloc you must be easily entertained! Look Warmunists up in the dictionary just for fun.

Yes climate change is just a commie plot, probably caused by China so they can take over the world!

Even Crypto Poilievere and Steve Harper say human caused climate change is real. They must be “Warmunists" too! LOL

Hmmm, you didn’t respond to my post previous to my compliment of AB5’s wonderful word creation. Very telling. I said climate change policies are really about increasing the size and reach of government!!
