This is shown in a study carried out by ICTA-UAB, which warns of an increase in average maximum temperatures of 4ºC and average minimum temperatures of 3.5ºC if greenhouse gas emissions are not drastically reduced.
This is shown in a study carried out by ICTA-UAB, which warns of an increase in average maximum temperatures of 4ºC and average minimum temperatures of 3.5ºC if greenhouse gas emissions are not drastically reduced. Temperatures could reach values above 45ºC in urban inland areas of the AMB and above 42ºC in interior areas of the city of Barcelona.
The research, recently published in the Journal of Geophysical Research – Atmospheres, focuses on heat wave episodes in the AMB over the past 30 years (1991-2020) and projects these events towards the middle and end of the century. Using the Pseudo Global Warming (PGW) method and high spatial resolution urban meteorological modeling (1 km), the study simulates how the most common meteorological conditions recorded in recent decades would evolve if repeated under the climatic conditions forecast for mid-century (2041–2070) and end-century (2071–2100). The researchers considered a scenario in which regional and global conflicts continue, and the reduction of greenhouse gases remains not a priority, thereby producing an expected rise in CO2 emissions to nearly double that of current levels by 2100.
The study allows identifying which meteorological conditions would be altered to a greater or lesser extent by global warming. The results show a notable increase in maximum temperatures and the “urban heat island” effect, particularly in cities, as well as a reduction in relative humidity and changes in sea breezes.
