Late autumn–winter precipitation in northeast Turkey

January 27, 2012

Jex et al. published a short paper in Quaternary Research about speleothem-derived reconstruction of late autumn–winter precipitation in Gümüşhane, northeast Turkey. The observation goes back to ~ AD 1500 leading to the first long winter precipitation reconstruction for this region.

Remarkably extensive glaciation in Turkey near the Pleistocene-Holocene boundary

December 26, 2011

A new paper was published in GSA’s Journal of Geology by Zreda and others in November 2011. This is their media paragraph published in the journal’s web site: “Looking at how climate changed in the geological past can provide a useful perspective for studying modern climate change and for predicting climate changes in the next century. Dr Marek Zreda of the University of Arizona and his colleagues used mountain moraines to reconstruct the former glaciers and to determine climatic changes in Turkey at the beginning of the Holocene, the current interglacial epoch. They found that the glaciers were unusually large for that time, with snow lines lower than today by more than 1400 meters, implying a temperature 9°C lower than modern long-term average temperature. The main glacier melting phase lasted 500 years during which the ice margin retreated at the average rate of 1700 m per century, which is higher than modern gracier retreat rates computed over comparable time. This corresponds to the temperature increase at the rate of 1.4°C per century, which exceeds the global warming trend of the past century, 0.6°C, showing that natural causes can lead to fast and large climate changes, and that the magnitude and the rate of climate change observed in the past century are not unprecedented.” Please see more details and the paper here doi:10.1130/G32097.1

Solar energy for sustainable future of Turkey

October 7, 2010

Solar energy map of Turkey (from Kaygusuz, 2010)

A review on solar energy potential of Turkey is published in the Journal of Renewable and Sustainable Energy Reviews by Dr. Kaygusuz from Karadeniz Technical University. He claimed in the paper that the Concentrating Solar Power (CSP) generation has the potential to become cost-effective energy production of Turkey in the future as the electricity demand of Turkey is rapidly increasing. Turkish government recently supporting the development of this type of technology strongly. For more details please go to doi:10.1016/j.rser.2010.09.042

 

Heat wave changes in Turkey

March 25, 2010

A new data set of daily maximum and minimum summer air temperatures from 246 meteorological station in Turkey and from surrounding region (Eastern Mediterranean) revealed an increase trend in summer heat waves since 1960s (Kuglitsch et al., 2010). (A heat wave is defined as a period of three or more consecutive hot days and nights not interrupted by more than one non‐hot day or night). According to this new data, published in GRL, the heat wave intensity, heat wave length and heat wave number increased by a factor of 7.6 ± 1.3, 7.5 ± 1.3 and 6.2 ± 1.1, respectively. Over the whole area, summer time temperatures increased by ~0.34°C per decade, since 1960. The most pronounced increase were along the eastern parts of Turkish Black Sea coastline, in western, southwestern, and central Turkey, and across the Western Balkans. The impact of heat waves may include increase of heat related deaths, morbidity, effects on  infrastructures, and consequent impacts on society, agriculture, industry, ecosystem, services and tourism. doi:10.1029/2009GL041841
