A Nova Economia do Clima

NOVA IORQUE – Esta sexta-feira, na sua última avaliação detalhada das provas do aquecimento global, o Painel Intergovernamental das Nações Unidas sobre a Mudança Climática mostrará que os cientistas mundiais do clima estão mais certos que nunca que a actividade humana – principalmente a queima de combustíveis fósseis – está a causar o aumento das temperaturas e dos níveis do mar.

Em anos recentes, uma série de catástrofes climáticas extremas – incluindo o Furacão Sandy em Nova Iorque e Nova Jérsia, cheias na China, e secas no Meio-Oeste Americano, na Rússia e em muitos países em desenvolvimento – causou danos enormes. Na semana passada, o México foi alvo de furacões simultaneamente no Pacífico e no Golfo do México que devastaram vilas e cidades no seu caminho. A mudança climática é um impulsionador importante destas catástrofes, e arriscamo-nos a muito pior.

Isto coloca um novo debate no centro das atenções: como reconciliar o reforço do combate à redução de emissões de gases com efeitos de estufa com um crescimento económico forte.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
