“Many of the observed climate changes are unprecedented in thousands, if not hundreds of thousands of years, and some of the changes that have already begun – such as continued sea level rise – are irreversible over hundreds or thousands of years.” noted experts.
According to them, sustainable reductions in carbon dioxide and other greenhouse gas emissions will limit climate change. Air quality will improve quickly, but global temperatures may take 20-30 years to stabilize.
The experts emphasized that all regions are faced with climate change, and its consequences will increase over time.
“A global warming of 1.5 ° C will increase heat waves, longer warm seasons and shorter cold seasons. The report indicates that with a global warming of 2 ° C, extreme temperatures are more likely to reach critical thresholds for agriculture and health.” , – noted in the message.
What climate change will affect:
- climate change is increasing the water cycle. This causes more intense rainfall and related flooding in some regions and more severe drought in others;
- climate change affects the pattern of precipitation. At high latitudes, precipitation is likely to increase, while it is projected to decrease over most of the subtropics;
- coastal areas will continue to rise in sea level during the 21st century, leading to more frequent flooding in low-lying areas and coastal erosion;
- further warming will intensify the melting of permafrost and the shrinking of glaciers in the Arctic.
The Paris Climate Agreement entered into force in November 2016, it involves measures to prevent climate change… To begin its operation, it is necessary that the document be ratified by at least 55 countries, which together emit more than 55% of greenhouse gases in the world. The agreement is intended to replace the Kyoto Protocol, which enshrined standardized obligations to reduce greenhouse gas emissions. The document has already been ratified by more than 180 countries, including Ukraine.
2020 year became unprecedented in extreme weather and climate disastersUN Secretary General António Guterres said on May 6, 2021. He said that humanity is heading “towards a catastrophic 2.4-degree rise in temperature by the end of the century.”
