Study Notes

Impact of Climate Change on Iberian Peninsula and Balearic Spain

Climate change is altering temperature and precipitation patterns in the Iberian Peninsula and Balearic Islands, impacting plant communities.
Data from 3668 weather stations across the region were analyzed.
Comparing the 35-year periods (1953–1987 and 1988–2022) showed an increase in the Mediterranean macrobioclimate, up by 6.93%, primarily at the expense of the Temperate macrobioclimate.
Bioclimatic trends in the Mediterranean region show increased xeric and continental conditions, while temperate areas show homogenization of climate conditions.
Two new bioclimates were discovered, indicating emerging climate conditions.
These findings have crucial implications for biodiversity, especially in mountainous and transitional areas where endemic species face increased habitat loss risk.
This study provides a foundation for developing targeted conservation strategies, establishing a baseline for future monitoring, and creating early warning systems for vulnerable ecosystems.
The study supports developing climate-adapted conservation measures for the region.

Climate Change Impacts in the Study Area

Temperature increases in the Iberian Peninsula between the 1970s and 1990s followed by stagnation until 2015.
Significant summer and late spring temperature increases were observed.
Regional analysis supports the trend of more significant warming in later seasons.
Precipitation across Spain decreased notably since 1950, especially along the Mediterranean coast.
Increased precipitation intensity occurred in certain valleys (Ebro and Guadalquivir) along with longer drought periods.
Significant declines in precipitation have been observed in various regions, such as the Ebro, Iberian System, northern Baetic System, and Jucar, and Segura River basins.

Bioclimatic Indices and Units

Bioclimatology studies the relationship between climate and the distribution of plant communities.
Bioclimatic units (based on Rivas-Martínez et al., WBCS) are valuable tools to analyze the impacts of climate change on ecosystems, particularly regarding precipitation and temperature variables.

Data Analysis and Methodology

A dense network of weather stations (3668) data was used for daily temperature and precipitation measurements.
Data quality and continuity were ensured through homogenization and gap-filling processes.
Analysis of two 35-year periods (1953-1987 and 1988-2022) was conducted.

Bioclimatic Changes Detected

Significant expansion of the Mediterranean macrobioclimate and contraction of the Temperate macrobioclimate.
Several bioclimatic changes emerged, with notable fluctuations in their occupancy, including the observed increases in Mediterranean bioclimates and decreases in temperate bioclimates.
Significant shifts were seen in the Mediterranean region, with an increase in xeric (drought-resistant) conditions.
New bioclimates (Teco and Medc) emerged during the later period(1988–2022), signifying shifts in climate conditions.

The Importance of the Study

The observed changes have broad implications for biodiversity conservation and management, especially in vulnerable areas.
These findings highlight the need for specific conservation measures and strategies to address future climate conditions.
Enhanced climate monitoring for vulnerable ecosystems and biodiversity management planning are necessary.
