could increase by an average of 18.4%, 47.8% and 69.0% in the 2020s, 2050s and 2080s, respectively, under RCP4.5 and by 16.6%, 73.8% and 134%, respectively, under RCP8.5 relative to a 1980s baseline . Projections of temperature-related mortality from CVD for Beijing in the 2080s vary depending on RCP and population assumptions . Projections for Ningo, China, suggest heat-related years of life lost  could increase significantly in the month of August by between 3 and 11.5 times over current baselines by the 2070s, even with adaptation . Yang and colleagues project that heat-related excess CVD mortality in China could increase to approximately 6%  by the end of the century under RCP8.5 and to over 3% under RCP4.5 . The future burden of temperature-related myocardial infarctions in Germany is projected to rise under high emissions scenarios , while in the eastern USA, Limaye et al.  projected an additional 11,562 annual deaths  by mid-century due to cardiovascular stress in the population 65 years of age and above. CVD mortality in Brazil is projected to increase up to 8.6% by the end of the century under RCP8.5, compared with an increase of 0.7% for RCP4.5 .
