June 29 (UPI) – Increasingly, climate scientists are demanding that climate models focus more on CO2 levels and less on temperature.
According to a new study, researchers at the University of Exeter slow even though an increase in CO2 accelerates. Not only do current models ignore this reality, but the authors of the study suggest that they do not account for the myriad of CO2 impacts on biology – life
. Current models use too narrow a range to describe future CO2 concentration. the impact of gas on plants and animals.
"Higher CO2 concentrations cause increased growth of many plant species," Exeter researcher Richard Betts said in a press release. "This causes a general greening of vegetation, but also changes the composition of ecosystems – some species do better than others. Large, slow-growing tree species can lose competitors faster."
Higher CO2 Levels Can Both of these factors can potentially improve crop yields, which could help offset some of the negative impacts of climate change – although in some cases plants may use fewer crops than others. water, which can reduce the impact of droughts on local ecosystems. this happens, the nutritional value of crops can be reduced due to additional CO2, "said Betts." The rise in CO2 also causes ocean acidification that is damaging to corals and some species of plankton. "
New research does not diminish the threat of global warming Recent studies have suggested that increasing CO2 levels could pose a variety of serious threats even though warming plateau rates.
The last article – published this week in the journal Nature Climate Change – suggests that the impacts of increasing CO2 levels are likely to prove
But the details buried in this mixed bag will only be revealed if climatologists start to Focus more on the impact of raising CO2 levels on biological systems
.We need to consider these other s effects of CO2 as well as those of rising temperatures, "said Betts.
Betts and his research partners have not attempted to predict the impacts of different levels of CO2 on biological processes. Their goal was to show that a wider variety of CO2 levels is compatible with different warming scenarios.
"Instead of calculating the probability of some warming if the CO2 doubles, we calculated the probability of a particular level of warming increase," Betts said. "This allows us to estimate what would be the range of CO2 concentrations when global warming would pass these levels, if CO2 was the only thing in the atmosphere that we are changing."
