90 percent of the world’s population will experience heat and drought at the same time
Oxford University scientists estimate that by the end of the 21st century, about 90 percent of the world’s population will experience both extreme heat and drought.
This, notes Nature Sustainability, will exacerbate social inequalities and undermine efforts to reduce carbon emissions.
Heat waves and drought are the worst climatic conditions that threaten the sustainable development of mankind. However, the physical mechanisms underlying these climatic conditions and their impact on the social environment have not been studied in detail.
The researchers used a 111-component climate hydrological model to predict how global warming will affect heat and drought.
It appears that the frequency of extreme 10-fold carbon emissions worldwide under a worst-case scenario of peak carbon emissions will increase with uneven negative impacts on agro-ecosystems and socio-economic productivity by the end of the 21st century.
And that low humidity and temperature contribute to slowing down the processes of carbon sequestration in terrestrial ecosystems and the production of oxygen more than the action of each factor separately. In addition, the poor often live in vulnerable areas and have limited survival options, so they are more vulnerable to or more vulnerable to natural disasters than the rich. While residents of urban areas are more able to adapt and reflect the impact of natural disasters compared to rural residents.
