Essa perda ter\u00e1 consequ\u00eancias diretas sobre os ecossistemas e as comunidades que dependem dessas fontes de \u00e1gua para sua sobreviv\u00eancia.\u00a0O derretimento das geleiras altera o ciclo da \u00e1gua, resultando em mudan\u00e7as nos padr\u00f5es de fluxo e aumentando a probabilidade de desastres naturais, como inunda\u00e7\u00f5es e deslizamentos de terra. Entre 1985 e 2014, a diminui\u00e7\u00e3o da massa das geleiras foi respons\u00e1vel por 713 eventos clim\u00e1ticos extremos, que causaram perdas econ\u00f4micas estimadas em US$ 56 bilh\u00f5es e resultaram em mais de 39 mil mortes.<\/p>\n<p style=\"text-align: justify;\">O relat\u00f3rio tamb\u00e9m revela que 2,2 bilh\u00f5es de pessoas ainda carecem de acesso \u00e0 \u00e1gua pot\u00e1vel, enquanto 3,5 bilh\u00f5es vivem sem saneamento b\u00e1sico adequado. Para enfrentar esses desafios, o documento sugere a necessidade de aprimorar a coleta e a qualidade dos dados relacionados \u00e0s geleiras, al\u00e9m de ressaltar a import\u00e2ncia do conhecimento ind\u00edgena e da participa\u00e7\u00e3o das comunidades na gest\u00e3o dos recursos h\u00eddricos.\u00a0Por fim, o estudo aponta que s\u00e3o necess\u00e1rios investimentos anuais de cerca de US$ 187 bilh\u00f5es para que os pa\u00edses em desenvolvimento nas regi\u00f5es montanhosas consigam se adaptar \u00e0s mudan\u00e7as clim\u00e1ticas. No entanto, atualmente, o fluxo financeiro dispon\u00edvel para essa adapta\u00e7\u00e3o \u00e9 de apenas US$ 13,8 bilh\u00f5es, o que evidencia a urg\u00eancia de a\u00e7\u00f5es mais robustas para enfrentar a crise h\u00eddrica global.<\/p>\n<p style=\"text-align: justify;\"><em><strong>JP NEWS<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Derretimento das geleiras altera o ciclo da \u00e1gua, resultando em mudan\u00e7as nos padr\u00f5es de fluxo e aumentando a probabilidade de desastres naturais, como inunda\u00e7\u00f5es e deslizamentos de terra O Relat\u00f3rio Mundial de Desenvolvimento H\u00eddrico de 2025, elaborado pelas\u00a0Na\u00e7\u00f5es Unidas, traz um alerta significativo sobre os efeitos do aquecimento global nas geleiras.
