Shorter plants = higher CO2 levels!
Updated: Aug 3, 2021
This is demonstrated by a US study: by lowering the vegetation, it needs less water but absorbs a lower amount of carbon dioxide from the atmosphere!
Some plants shrink, trees cut their foliage, leaves and fruits shrink into bonsai size. A decrease, it is not known whether happy or not, but forced by the climatic changes that have severely tested the sweating of the plant for about twenty years, reducing more and more the amount of water available for the body. This downward metamorphosis is mainly due to prolonged drought seasons and increased solar radiation, according to research from the University of Minnesota and Western University of Canada published in the international journal Global Change Biology.
Conifers and annuals go down in size. Some more delicate varieties of wheat, after only five days of water stress, begin to fail; others stronger seem to be immune to it. But in order to adapt to the new conditions, 84% of the 112 species of 49 plant families analyzed in the study would be willing to give up some of their measures already by 2050. The most affected will be gymnosperms, such as pine and fir, and annuals such as hemp or corn.
Also at risk are the plant communities of the bogs, the wildflowers of the prairies and the trees of the boreal forests. Ferns are saved, which have proven to be able to withstand this climatic difference, while others, such as the rose, could remain the same high but with fewer flowers. Global warming favours a smaller kind of vegetation. "In reality - explain the biologists in the recently published paper - the long-term consequences of this phenomenon are more complex and have direct effects not only on the size of the plant but on cells, leaves, shoots, roots and reproductive organs". It applies to those that grow freely in nature and the ones cultivated, such as cereal family and fruit species such as cherry and peach.
