Reduction in pollution can tighten global warming : journal Nature
A new study published in the journal Nature has revealed that taking strong and rapid steps to cut emissions of carbon dioxide and other greenhouse gases will help reduce global warming rates over the next 20 years. The study underlines that taking immediate steps to stop climate change can bring benefits in the current life itself. You do not have to wait long for this in future.
Scientists already agree that if the emission of polluting elements is cut sharply and deeper than before, this could limit global temperature increases in the latter half of this century. However, over the next few decades it has become more challenging to achieve very short term gains. In particular, can also cause fluctuations in the natural cycle, the temperature of the global atmosphere and ocean systems which can mask the temporary effects of human activities on climate.
But a new way of combining large-scale data from various sources by Leeds University has solved human-induced warming on a much shorter time scale than natural variability.
Nature with Simuleshns thousands of different climate models climate published in the change in this study, there was a feeling of went uses multiple estimates of natural climate variability in order to ascertain that various levels of emission reductions over the next two decades global How can it affect warming?
The facts that emerged in the report show that the Paris Agreement aims to push efforts to reduce emissions of polluting elements and to keep global temperatures rising below one-and-a-half degrees Celsius levels before the industrial era. Next to cut emissions Warming will have a significant impact over the course of 20 years. Despite natural variability, this effect will be seen.
In fact , the threat of warming , which has become much stronger than before, continues to be a major dependence on fossil fuels, with rapid and intensive cuts in emissions of polluting elements Of the future “Will be 13 times the average. Next in a position to use fossil fuels extensively One can see an increase in global temperature from one to one and a half degree Celsius during 20 years. This means that the year Commitments expressed under the Paris Agreement long before 2050 would fail.
The lead author of the study, Doctor Christine McKenna, is a Post Doctoral Research Fellow in Leeds and is working on an EU-funded constancy project.
McKenna said ” Our results show that future generations will not feel benefited only by rapid and deep cuts in emissions of polluting elements.” If steps were taken from now on, it would mean that we could prevent global warming from accelerating in the coming few decades. Also, in the long run, we can reach our goal of limiting the temperature rise.
He said that through this we have to avoid those effects Can also help, which is faster in temperature And may arise through extreme changes.
McKenna said ” World temperature per decade at the moment Rising to 0.2 ° C. If we immediately If we do not take steps, we can clearly see Paris The findings of this report will fall from the threat of violation of the agreement. Setting more difficult targets for greenhouse gases emissions and zero for government parties Pollution-free compensation for damage to economy due to Kovid- 19 epidemic with emission targets Will encourage more. ”
