According to the United States' National Oceanographic and Atmospheric Administration the first five months of this year were the warmest on record going back to 1880. US economist Jeffrey D. Sachs comments in the business paper Jornal de Negócios: "The US bears disproportionate responsibility for inaction on climate change, because it was long the world's largest emitter of greenhouse gases, until last year, when China overtook it. Even today, per capita US emissions are more than four times higher than China's. ... When Barack Obama was elected US president, there was hope for progress. ... Strangely, despite being a candidate of change, Obama has not taken the approach of presenting real plans of action for change. ... Whether this is an intended outcome ... is difficult to determine. What is clear is that we are courting disaster as a result. Nature doesn't care about our political machinations. And nature is telling us that our current economic model is dangerous and self-defeating. Unless we find some real global leadership in the next few years, we will learn that lesson in the hardest ways possible." (16/08/2010)
