abstract = "This work aimed to evaluate changes in water balance components
(precipitation, evapotranspiration, and water availability) and
precipitation extremes projected under global warming levels
(GWLs) of 1.5 °C and 2 °C, in Brazil. An ensemble of eight
twenty-first-century projections with the Eta Regional Climate
Model and their driving Global Climate Models (CanESM2,
HadGEM2-ES, MIROC5, and BESM) were used. Projections of two
Representative Concentration Pathway scenarios, RCP4.5 and RCP8.5,
considered intermediate and high concentration, respectively, were
used. The results indicate that the RCP8.5 scenario under 2 °C GWL
is likely to have a higher impact on the water balance components,
amplifying trends in drier conditions and increasing the number of
consecutive dry days in some regions of Brazil, particularly in
the North and Northeast regions. On the other hand, the
projections indicate the opposite sign for the South region, with
trends toward wetter conditions and significant increases in
extreme rainfall. The 0.5 °C difference between the GWLs
contributes to intensifying reductions (increases) from 4 to 7% in
water availability, mainly in the North-Northeast (South) regions.
The projected changes could have serious consequences, such as
increases in the number of drought events in hydrographic regions
of the Northeast region of Brazil and increases in flood events in
the South of the country. The results here presented can
contribute to the formulation of adaptive planning strategies
aimed at ensuring Brazils water security towards climate change.",
