👉The frequency and intensity of extreme heat events are increasing in Cyprus, as in the rest of the world, heightening the health risks and productivity loss for workers both outdoors and indoors. In a joint effort between CARE-C and EEWRC researchers of the Cyprus Institute to assess the heat's impact on labour productivity, we used climate and biological data to calculate physical heat stress indicators for different levels of work intensity and sun exposure. Then, combining the projected physical impacts with economic data, we assessed that lost economic output due to hotter working conditions may amount to 101 million Euros in 2030, or 0,4% of GDP, and 303 million Euros in 2050, or 0,7% of GDP. Cumulative economic losses up to 2050 could reach 0,5% of the entire GDP of Cyprus of that period, if no further adaptation measures are taken in workplaces.

Our study is the first one using Cypriot data to estimate the economic damage caused by lost work hours due to extreme heat. Most European countries may face greater losses in labour productivity due to climate change because their indoor workplaces are not adequately adapted, but the impacts on the most vulnerable and exposed workers in Cyprus may also be severe and require adaptation measures to monitor and protect workers’ health.
This Policy Brief summarizes our work.

Μελέτη στο Nature αποκαλύπτει νέο βασικό μηχανισμό σχηματισμού νεφών με συμβολή του Ινστιτούτου Κύπρου

Νέα διεθνής μελέτη, που δημοσιεύθηκε στο κορυφαίο επιστημονικό περιοδικό Nature με καθοριστική συμβολή του Ινστιτούτου Κύπρου, προσφέρει σημαντικές νέες γνώσεις για τον σχηματισμό των νεφών και τη λειτουργία του κλιματικού συστήματος της Γης.

Η έρευνα καταδεικνύει ότι οι φυσικές εκπομπές από τους ωκεανούς επηρεάζουν τον σχηματισμό των νεφών σε πολύ μεγαλύτερο βαθμό απ’ ό,τι θεωρείτο μέχρι σήμερα. Τα ευρήματα συμβάλλουν στην επίλυση μιας μακροχρόνιας ασυμφωνίας μεταξύ παρατηρήσεων της ατμόσφαιρας και κλιματικών μοντέλων και αναμένεται να βελτιώσουν την ακρίβεια των κλιματικών προβλέψεων.

Η Δρ Rima Baalbaki, ερευνήτρια στο CARE-C του Ινστιτούτου Κύπρου και πρώτη συγγραφέας της μελέτης, σημείωσε ότι η καλύτερη κατανόηση αυτού του μηχανισμού επιτρέπει πιο ολοκληρωμένη κατανόηση της λειτουργίας του κλιματικού συστήματος και συμβάλλει στη βελτίωση της αξιοπιστίας των κλιματικών προβολών.

Ο Αναπληρωτής Καθηγητής Δρ Θεόδωρος Χριστούδιας υπογράμμισε ότι τα ευρήματα έχουν ιδιαίτερη σημασία για την Κύπρο και την Ανατολική Μεσόγειο, μία από τις πλέον ευάλωτες περιοχές στην κλιματική αλλαγή, καθώς ενισχύουν την ικανότητα προετοιμασίας και προσαρμογής στις επιπτώσεις της.

Τα αποτελέσματα παρουσιάστηκαν και σε συνέντευξη Τύπου που πραγματοποιήθηκε στο Ινστιτούτο Κύπρου στις 26 Ιουνίου 2026, στο πλαίσιο της ευρύτερης διάχυσης των ευρημάτων.

Η δημοσίευση στο Nature αναδεικνύει τη συμβολή της ερευνητικής κοινότητας του Ινστιτούτου Κύπρου στην πρόοδο της διεθνούς έρευνας για το κλίμα και την ατμόσφαιρα, καθώς και τη σημασία της για την ενίσχυση της ανθεκτικότητας της περιοχής απέναντι στην κλιματική αλλαγή.

Nature study reveals key driver of cloud formation with contribution from The Cyprus Institute

A new international study published in the leading scientific journal Nature, with a major contribution from The Cyprus Institute, provides important new insights into cloud formation and the Earth’s climate system.

The research shows that natural ocean emissions play a greater role in cloud formation than previously understood. The findings help explain longstanding differences between atmospheric observations and climate model predictions and are expected to improve the accuracy of future climate projections.

Dr. Rima Baalbaki, researcher at the Climate and Atmosphere Research Center (CARE-C) of The Cyprus Institute and first author of the study, noted that a better understanding of this mechanism allows scientists to gain a clearer picture of how the climate system operates and to improve the reliability of climate projections.

Associate Professor Dr. Theodoros Christoudias highlighted that these findings are particularly important for Cyprus and the Eastern Mediterranean, one of the regions most vulnerable to climate change, as they contribute to strengthening preparedness and resilience.

The findings were also presented at a press conference held at The Cyprus Institute on 26 June 2026 as part of the broader dissemination of the results.

The publication in Nature underscores the contribution of The Cyprus Institute’s research community to advancing international climate and atmospheric science and highlights its relevance for strengthening climate resilience in the region.
