Elevated CO2 and Crop Chemistry

ESSENTIAL reading and research for the ‘failing’ Guardian and New York Times respectively, who both launched new attack pieces on essential trace gas CO2, claiming this time that “Climate change [CO2] will make rice less nutritious”… 🤔

Before it was expropriated by the global warming/climate change movement, the term “Greenhouse Effect” referred to the effect of elevated carbon dioxide in greenhouses on crop chemistry. We know from greenhouse studies going back to the late 19th century that crop chemistry reflects the balance between soil chemistry, air chemistry, and light intensity. The important features of air chemistry are the availability of carbon dioxide for photosynthesis and of oxygen for plant respiration. The important features of soil chemistry are the availability of water, nitrates, phosphates, and minerals.

Greenhouse operations irrigation, air circulation to maintain air quality, heating for temperature control, the introduction of carbon dioxide to maintain elevated carbon dioxide levels of 1000 to 2000 parts per million for photosynthesis enrichment, and the availability of sufficient light for photosynthesis to occur. Photosynthesis enrichment improves crop yield and corresponding changes to soil chemistry must also be maintained to preserve the…

ATTENBOROUGH : ‘Climate Change Stops Plants Growing’

OVER the years, TV naturalist Sir David Attenborough has wowed us all with that mesmerising voice narrating epic visuals of all things nature. Aesthetics aside, and not doubting the man’s intelligence, Attenborough persists in parroting easily demolished propaganda about the threat of ‘climate change’.

IN the BBC1 series on Africa he claimed that the wildlife there was at a “pivotal moment in their history” and “Africa’s climate is certainly changing. Some parts of the continent have become 3.5C hotter in the past 20 years.”

WHEN challenged, the BBC indicated that the claim of a 3.5C rise over 20 years was sourced from a Christian Aid report. The BBC acknowledged that the 3.5C claim, based on that NGO source, had no basis in fact and the statement would be removed when the program was repeated.

GLOBAL warming’s favourite mascot – polar bears – haven’t escaped his misinformed activism. The Oasis Nature Channel, of which Attenborough lent his name and reputation to, presented a series of programs entitled Extinctions, about animals under threat. The first of the series was about polar bears, which they referred to as the canaries in the global-warming coalmine, ignoring the fact that polar bear numbers are actually the highest since records began.

ATTENBOROUGH’S resume wouldn’t be complete without paying homage to UN “sustainability” (Agenda 21) and the tenets of Thomas Malthus


IN his latest eye-rolling rant, Attenborough claims that climate change “stops plants growing” and that global warming will create a “plant-less desert” !

Sir David Attenborough marks the reopening of the Temperate House at Kew Gardens, the largest Victorian glasshouse in the world this evening. He praises conservation work being done at the botanical gardens to preserve plants which otherwise would die, due to climate change. Kew Gardens is currently finding and researching species of plants that can help restore land affected by global warming, instead of letting our landscape become a “plantless desert”.

Attenborough: Kew preserves rare plants – BBC News

ASSUMING that climate change aka global warming equates to an increase in carbon dioxide emissions, (I say ‘assuming’, because climate change aka global warming can mean whatever an alarmist wants it to mean depending on their particular eco-grievance of the day) then it would appear our favourite ye-olde botanist has officially exchanged brains for blunts, in claiming that climate change “stops plants growing” !

BACK ON THE ‘BLUE PLANET’, DAVID >> Carbon dioxide = plant food!

OH Noes! Increased Carbon Dioxide Making More Flowers In Tropical Forests

“PLANTS convert atmospheric carbon dioxide into energy in the form of sugars, which they can use to fuel any number of vital life processes. As more carbon dioxide is released into the atmosphere, plants have an opportunity to produce a bounty of new energy.”

SHOCK HORROR!! Carbon Dioxide (CO2) and warmth are what eco-systems require to flourish 😱

Watts Up With That?

From FLORIDA STATE UNIVERSITY and the “but wait, all climate change must be bad!” department.

Climate change linked to more flowery forests, FSU study shows

TALLAHASSEE, Fla. — New research from a Florida State University scientist has revealed a surprising relationship between surging atmospheric carbon dioxide and flower blooms in a remote tropical forest.

FSU researchers studying the rich tropical forests of Panama’s Barro Colorado Island found that climbing rates of carbon dioxide have set the stage for a multidecade increase in overall flower production.

The findings were outlined in a paper published in the journal Global Change Biology

“It’s really remarkable,” said Assistant Professor of Geography Stephanie Pau, who led the study. “Over the past several decades, we’ve seen temperatures warming and carbon dioxide increasing, and our study found that this tropical forest has responded to that increase by producing more flowers.”

Pau’s findings suggest that tropical forests, which…

Study suggests increased atmospheric CO2 created a 30% growth in plant photosynthesis during last two centuries

“Photosynthesis is the process through which plants use sunlight to convert carbon dioxide (CO2) into carbohydrates to fuel their growth and other activities”

Carbon dioxide – the essential gas of life on earth, without which we’d all be dead.

It is the very same gas that “Save The Planet” eco-zealots and sycophant climate-obsessed mainstream media refer to as “carbon pollution”.

It is the same essential gas of life that Barack Obama had written in law, via the EPA, as a “Pollutant”!

The demonisation of colourless, odourless, essential trace gas and plant food “CO2/Carbon Dioxide” – one of the great deceptions of the Climate Change scandal.

Watts Up With That?

From the UNIVERSITY OF CALIFORNIA – MERCED and the “CO2 is plant food, but, it’s still terrible department” (see text)

Research shows global photosynthesis on the rise

Plant photosynthesis was stable for hundreds of years before the industrial revolution, but grew rapidly in the 20th century, according to new research published today in Nature.

“Virtually all life on our planet depends on photosynthesis,” said UC Merced Professor Elliott Campbell, who led the research. “Keeping tabs on global plant growth should be a central goal for the human race.”

Photosynthesis is the process through which plants use sunlight to convert carbon dioxide (CO2) into carbohydrates to fuel their growth and other activities.

Yet, researchers lack…

Can’t See Forests for the Theory

“Too bad so much effort and funding is wasted on IPCC circuses.”

The global warming aka climate change meme is simply the latest attempt by leftists to trick society into remaking itself in their image. It was never about science. It was always about power and money.

Science Matters

Warming alarmists see no good coming out of rising CO2 and the current climate optimum, and their warnings extend to forests as well. So in love with their theory of global warming, they cannot see the forests as they are, and as documented in numerous research studies.

Claim: Forest growth is diminished by higher CO2 and warmer summers.
Fact: CO2 increases have improved forest health.

Claim: Forest areas will be hard-hit by future droughts.
Fact: No trend in droughts is discernible.

Claim: Warmer temperatures increase damage from pests and pathogens.
Fact: Enhanced CO2 is making forests more resilient to diseases and infestations.

Claim: Old growth forests will not sequester CO2 as young forests do.
Fact: Rising CO2 has given new life even to aging forests.

Basic Vegetation Biology (from Bill Illis here)

Almost ALL C3 pathway vegetation (trees, bushes, wheat, rice and 95% of all plants) are CO2-starved except in extremely…
