Middle East and North Africa to Face Alarming Temperature Surge, Experts Warn

Accelerated Climate Change Threatens the Rigion

A recent study highlights that the Middle East and North Africa, already among the hottest and driest regions globally, are experiencing accelerated climate change, likely reaching critical warming thresholds 20 to 30 years ahead of other areas. By the end of the century, regions of the Arabian Peninsula may face temperature increases of up to 9°C (16.2°F).

The region, already known for record-breaking summer heat, is nearing an average warming of 2°C (3.6°F) above pre-industrial levels. Further temperature increases could render certain areas uninhabitable without adaptive strategies.

Paris Agreement Goals Surpassed in the Region

"The Paris Agreement emphasizes limiting global warming to 1.5°C, with a maximum threshold of 2°C," explained Abdul Malik, climate scientist at King Abdullah University of Science and Technology and lead author of the study. "However, parts of the Middle East and North Africa have already surpassed these thresholds."

The research has been published in the journal JGR: Atmospheres.

Developing Models for a Fast-Warming Region

The Middle East and North Africa, characterized by vast desert ecosystems, have populations primarily concentrated along coastal areas. Previous climate models have varied in their predictions, often misestimating regional warming and leaving scientists with an incomplete understanding of its nuances.

High-Resolution Analysis Offers New Insights

This study utilized CMIP5 and CMIP6 models to conduct a high-resolution analysis (81² km or about 50 mi²) of the Middle East and North Africa, offering a more detailed understanding of regional warming.

While earlier research has established that the region warms significantly faster than others, Malik highlighted, "Our findings reveal that the warming rate is uneven across the region, ranging between 1.5 to 3.5 times the global average."

The accelerated warming rate suggests that the Middle East and North Africa could hit 3-4°C (5.4-7.2°F) of warming approximately 30 years before the global average, with inland areas of the Arabian Peninsula particularly affected.

Temperatures Rise in a Hot Region

The Middle East and North Africa are home to some of the planet's hottest areas, with researchers forecasting sustained rapid warming. The central Arabian Peninsula is already warming up to three times faster than the global average, matching the pace of Arctic warming.

Projected Temperature Increase by 2100

By 2100, the Arabian Peninsula may experience an average temperature increase of 2.6°C (4.7°F) under low emission scenarios, and up to 7.6°C (13.7°F) under high emission scenarios.

This is due to the inability of the dry deserts in the Middle East and North Africa to cool down efficiently through soil moisture evaporation, unlike their humid equatorial counterparts around the world.

Desert Regions Warm Faster Than Polar Areas

"Desert regions warm nearly as quickly as polar regions, but with significantly higher temperatures," said Georgiy Stenchikov, a retired climate scientist and co-author of the study. "As a result, the temperature threshold is reached much sooner than in the polar regions."

Regional Variations in Warming and Potential Mitigation

Due to coastal cooling effects, densely populated regions along the southern and western coasts of the Arabian Peninsula, such as Oman, are not warming as rapidly as inland areas and the eastern coast of the peninsula.

The warming rates very across seasons. The study identified summer hotspots in central Arabian Peninsula regions, including Riyadh Province, and in Algeria, while winter hotspots were found in Mauritania and Iran's Elburz Mountains.

The Role of Emissions Targets and Adaptation

If global emissions targets are met, the warming rate in the Middle East and North Africa could decrease by as much as 38%. In addition, cities may mitigate extreme heat through urban greening and architectural innovations.

"Adaptation will be essential, and the Middle East and North Africa could serve as testing grounds for these measures," Stenchikov explained. "Global warming is a worldwide issue, and it cannot be contained in one area. However, artificial environments can be developed in densely populated regions."
