The main purpose of this ongoing blog will be to track global extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Main Topic: New Forecast of 5°C Temp Rise for Middle Eastern Area by 2100
Dear Diary. Most know that the Middle Eastern area or EMME (Eastern Mediterranean and Middle East) is one of the most vulnerable regions of the planet for climate change. Being a desert area, or at the very least very arid outside mountainous zones, water has always been a precious commodity. Residents in and near desert zines have always contended with high temperatures. Recently during the 2010s the Syrian Civil War was blamed on climate change, since a historic drought partially ignited that conflict.
So, what might further warming do to society and politics there moving farther into the 21st century? I cringe to think of suffering involved here. Now a new forecast has come out indicating that a further 5°C of warming might happen across the EMME by the year 2100. We will need to rapidly reign in fossil fuel use to prevent this, but all indications are we aren’t going to do so fast enough.
Here are details from PHYS.ORG:

Overall warming of up to 5°C in this century projected for the Eastern Mediterranean and Middle East
by Max-Planck-Institut für Chemie
Unprecedented and societally disruptive extreme weather events, including heat waves, droughts, dust storms and torrential rains, will soon become a reality unless immediate, ambitious, and transboundary climate action is taken, warns the latest scientific assessment of state-of-climate in the region.
A new report prepared by an international group of scientists and published in the journal Reviews of Geophysics, identifies the EMME as a climate change hot spot, and concludes that the region is warming almost two times faster than the global average, and more rapidly than other inhabited parts of the world. (The 17 countries included in the analysis of the report are Bahrain, Cyprus, Egypt, Greece, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Palestine, Qatar, Saudi Arabia, Syria, Turkey and the United Arab Emirates.)
For the remainder of the century, projections based on a business-as-usual pathway indicate an overall warming of up to 5°C or more, being strongest in the summer, and associated with unprecedented heat waves that can be societally disruptive. Further, the region will experience rainfall shortages that compromise water and food security. Virtually all socio-economic sectors are expected to be critically affected, with potentially devastating impacts on the health and livelihoods of the 400 million people of the EMME, with worldwide implications.
The report, which was prepared under the auspices of the Max Planck Institute for Chemistry and The Cyprus Institute, in preparation to COP27, which will take place in Egypt in November 2022, provides an updated, comprehensive assessment of measurement data and recent climate analyses, covering a wide range of time scales, phenomena and possible future pathways. It identifies the region as a climate change hot spot, and also signals that the EMME is rapidly overtaking the European Union as a source of greenhouse gases and becoming a major emitter at the global scale.
In addition to the average increase in temperatures, the researchers call attention to the emergence of extreme weather events with potentially disruptive societal impacts. These include the strongly increasing severity and duration of heatwaves, droughts and dust storms, and torrential rains which are expected to trigger flash floods. The assessment also comprises a discussion of atmospheric pollution and land-use change in the region, considering urbanization, desertification and forest fires, and includes recommendations for possible climate change mitigation and adaptation measures.
“Business-as-usual pathways for the future,” meaning projections assuming no immediate, ambitious climate action to avert the current climate trajectories, “imply a northward expansion of arid climate zones at the expense of the more temperate regions,” explains Dr. George Zittis of the Cyprus Institute, first author of the study.
As a result, mountainous climate zones with snow will diminish during this century. The combination of reduced rainfall and strong warming will contribute to severe droughts. The sea level in the EMME is projected to rise at a pace similar to global estimates, though many countries are unprepared for the advancing seas. “This would imply severe challenges for coastal infrastructure and agriculture, and can lead to the salinization of costal aquifers, including the densely populated and cultivated Nile Delta,” warns Zittis.
The projected changes will critically affect virtually all socio-economic sectors, particularly under a business-as-usual scenario. Jos Lelieveld, Director of the Max Planck Institute for Chemistry, Institute Professor at the Cyprus Institute and coordinator of the assessment, notes, “People living in the EMME will face major health challenges and risks of livelihood, especially underprivileged communities, the elderly, children and pregnant women.”
To avoid the most extreme of severe weather events in the region, the scientists highlight that immediate and effective climate action is urgent. “The motto of COP 27 is well chosen: Together for just, ambitious implementation now,” states Jos Lelieveld. “Since many of the regional outcomes of climate change are transboundary, stronger collaboration among the countries is indispensable to cope with the expected adverse impacts. The need to meet the goals of the Paris Agreement has become more important than ever,” says Lelieveld.
The study notes that meeting the main Paris Agreement targets could stabilize the annual temperature increase in the EMME to about 2°C by the end of the century, rather than the devastating 5°C which is projected under a business-as-usual scenario.
Possible adaptation options and policy recommendations noted in the report to contribute to meeting these targets stress the need for rapid implementation of decarbonization actions with a particular emphasis on the energy and transportation sectors, which dominate greenhouse gas emissions in the EMME. The report also stresses the importance of transformational changes toward climate resilience to adapt to increasingly challenging environmentally conditions. Priority areas include the coping with limited water resources and preparing for more frequent weather extremes such as heat waves that will be particularly challenging for the growing urban population.
The report was motivated by the Cyprus Government Initiative for Coordinating Climate Change Actions in the EMME, launched in 2019, aiming at the development of a joint Regional Climate Action Plan to address the specific needs and challenges EMME countries are facing, and advance coordinated action towards the goals of the Paris Agreement. At the political level, an EMME Heads of State Summit will be held in autumn 2022 when the Regional Action Plan is expected.
Ignoring climate change will lead to unprecedented, societally disruptive heat extremes in the Middle East
