Climate projections for the Arabian Peninsula show an increase in heat extremes, reduction in precipitation and sea level rise, all of which imply an intensification of the already extreme climatic conditions in the region. These changes affect the people and the land area but also the marine ecosystem of the Persian Gulf, where ocean acidification and further warming are combined stresses. For the inhabitants of Qatar, and its capital city Doha in particular, preparing for and adapting to these changes will be important, not least in a public health perspective and in an urban setting. QEERI is working with the Potsdam Institute for Climate Impact Research (PIK) on climate modeling and climate change impact research for assessing regional climate change and its impacts.
