The OTHER side of the greenhouse effect: how climate change Australia & # 39; greener & # 39; could make
Increased carbon dioxide and global warming will help plants grow better in Australia, according to a climate skeptic.
Christopher Monckton, known for challenging conventional climate science, said extra carbon dioxide in the atmosphere would help plants cope with the dry weather in Australia.
Lord Monckton – a former Margaret Thatcher adviser – said more carbon dioxide in the air meant that plants had fewer open stomata at the bottom of their leaves.
Stomata are small pores that plants use to absorb carbon dioxide, but they also release moisture, Lord Monckton told Daily Mail Australia.
Fewer stomata mean that plants lose less water in dry weather, he said.
Extra carbon dioxide in the atmosphere helps plants grow better with less water, climate skeptic Christopher Monckton told Thursday at a conference in Washington. Australian scientists reject this idea and say that short-term benefits do not help against drought

& # 39; So the plants and trees win twice with more carbon dioxide: once because carbon dioxide is vegetable food, and again because more carbon dioxide causes plants to lose less water. & # 39;
Australian scientist Martin De Kauwe, a plant physiology researcher at the University of New South Wales, said that although some elements of what Lord Monckton said were true, the conclusion was incorrect.
Dr. Kauwe is participating in an experiment with plant responses to increased carbon dioxide, the Eucalyptus Free Air CO2 Enrichment Experiment, conducted jointly with Western Sydney University.
For the experiment, Australian scientists are pumping carbon dioxide into parcels of trees to see how they will respond to the increased carbon dioxide levels expected in 2050.
Dr. Kauwe said that increased carbon dioxide increases the speed of photosynthesis in plants, but this does not always lead to more growth.
& # 39; There are no indications of an increase in their growth, & # 39; he said.
Although it is true that more carbon dioxide can make plants more water efficient in the short term, such as two to three days, Dr. said. Kauwe that his team had not found that more carbon dioxide would support an increase in resistance to drought.
The length of a dry spell counteracts the effect so that no benefit is gained, he said.
& # 39; If the drought lasts for months, it doesn't matter, & # 39; he said.

& # 39; It will make little difference to Australia's vegetation. & # 39;
Director Mark Howden of the Australian National University Climate Change Institute said that elevated carbon dioxide plants can make more leaves produce, meaning that they can lose more water in environments with a high CO2 content than in a low CO2 content.
The Monckton climate science challenge
Christopher Monckton presented new research on Thursday and challenged the mainstream on the following points:
* Doubled levels of carbon dioxide in the air in the next century would only heat the planet with 1.2 ° C and not 3.4 ° C as claimed by climatologists
* IPCC predictions of catastrophic temperature increases in response to doubled CO2 will not happen
* Modeling models for global warming made a mathematical error in calculating the feedback attributed to greenhouse gases
* The models incorrectly attributed climate feedback responses from reference temperatures including water vapor and sunshine to gases
* A team of interdisciplinary scientists examined the model, tested the theory and discovered the error, reducing the expected warming to 1.2 ° C
* As a result, global warming will be small, slow, harmless and beneficial
* Increased CO2 helps plants to flourish, making previously dry areas including Australia greener
* Satellite measurements show that the increased CO2 in recent decades has already increased the global biomass of plant life by 30%
Professor Howden said that Australia's soil contains poor nutrients that hinder the carbon dioxide growth response.
& # 39; So there are a few reasons why things are going wrong in Australia, & # 39; he said.
& # 39; With the predicted climate change for lower precipitation in the southern half of Australia and higher temperatures, this is likely to lead to a tanning of Australia. & # 39;
Lord Monckton, an independent investigator and activist, delivered two speeches at a climate conference on Thursday at the Trump International Hotel in Washington.
Monckton, who testified four times before the US Congress on Climate, told the conference that global warming in response to doubled carbon dioxide figures would be small, slow, and good for the planet.
Climatologists had made a mathematical error in calculating the carbon loop's feedback loop effect, predicting global warming up to ten times more than was realistic, he said in a media review.
Lord Monckton and a team of scientists, including professors of climatology, applied control theory, statistics and physics, have investigated climate models and then checked their results with a test circuit.

Rebel scientists say that doubling CO2 causes only 1.2C of warming, not predicted 3.4C, and will increase crop yields by stimulating plants with the CO2 they need for photosynthesis
They discovered that doubled levels of carbon dioxide in the air in the next century would only heat the planet by 1.2 ° C and not 3.4 ° C, as regular climate science says.
& # 39; That puts an end to the & # 39; climate emergency & # 39 ;, said Lord Monckton.
& # 39; Now that the team has corrected the error, global warming will be small, slow, harmless and beneficial, with valuable increases in crop yield and drought resistance. & # 39;
& # 39; Satellites show that the fertilization of plants by CO2, plant food, the total total biomass of green trees and plants – their & # 39; net primary productivity & # 39; – has already increased by 15-30 percent in recent decades. & # 39;
Dr. De Kauwe said in turn he was skeptical about the climate skeptics' argument, saying it was hard to imagine that different model groups from all over the world had all made the same mistake and had left the sun independently of each other.
& # 39; In Australia, temperatures have risen by 1 ° C since 1910 & # 39 ;, he said.
& # 39; The models were able to simulate the period for which we have observation records. If it was true that the feedback from the models had been omitted, they would not agree with observation. & # 39;
The 13th International Climate Conference was held by the free-market Heartland Institute think tank and organized speakers skeptical about regular climate science, such as Richard Lindzen, emeritus professor of meteorology at MIT, and Benny Peiser, director of the Global Warming Policy Forum.
& # 39; One of Australia's national poets has described Australia as & # 39; a land of droughts and floods & # 39 ;. That land is now becoming greener, thanks to extra CO2 in the air, which means that plants have fewer stomata, & # 39; Christopher Monckton told Daily Mail Australia
