Rising heat could affect human migration



A University College London study published in PLOS Climate concludes that rising temperatures due to the climate crisis are likely to affect human migration patterns.

Over the past decade, heat waves have been frequent and the surface temperature has been the warmest on record. With global warming, many people are expected to leave their homes to escape extreme temperatures. However, the exact role of heat in human migration is still unknown.

To clarify this relationship, a team led by Rita Issa has published research papers, annual reports, research papers, and papers investigating the effects of heat on human migration, or the heat experienced by migrants during migration. Conducted reviews of government documents and scientific literature.

Of the 32 studies investigating how heat affects migration, half found a correlation between heat exposure and the likelihood of people migrating.

Most of the 18 studies that evaluated the effects of heat on migrants on the move reported adverse health effects, including heat-related illness, heat stress, and premature mortality.

The study also found that people suffer more from the effects of heat when they live in areas with poor infrastructure, poor adaptation at work, low levels of education, and low socioeconomic status. It also shows that there are

New research suggests that heat can affect human migration patterns, including when people move, the risks they face along the way, and the heat they may experience after settling down. are doing.

However, the fact that only half of the included studies found a correlation between heat and migration suggests that heat alone is not the only factor driving migration.

The researchers point out that no study has shown a “temperature threshold” above which people can safely travel.

Instead, they propose developing a general method to compare temperature measurements, thermal effects, and environmental factors that drive migration, which could be used in the future to study climate change migration and formulate policy. support their efforts and protect them from harm.

“Migration is an effective adaptive response to extreme heat,” they added. In the UEA, where air conditioning is widely used, the poorest and most marginalized people, including migrants, are still often vulnerable to extreme temperatures. “

These conclusions, as they point out, are based on “decisive policies to curb global warming upwards through the reduction of carbon emissions and other greenhouse gases, as well as human vulnerabilities, including cities. It provides a dual opportunity for action called “Adaptation Strategy”. Planning, occupational accommodations and home renovations are undertaken to reduce the impact of heat on human health, well-being and productivity. “
