Unlike Donald Trump, world leaders take a pragmatic approach to climate change.
Hurricane Florence, which reached Category 4 (out of 5), weakened to a Category 1 before touching down on the North Carolina coast. It was soon downgraded to a tropical storm, with a wind speed of over 38 mph, but it is still causing damage due to flooding.
The storm locally dumped up to 30 inches of rain. There were more than 20 official deaths in the U.S. as of last Monday, September 17, and millions of people remain homeless.
On the other side of the globe, Typhoon Mangkhut plowed through the Philippines leaving dozens of victims, most of whom were miners buried in landslides. (Many are still missing.) Mangkhut then wreaked havoc in Hong Kong and the Chinese province of Guangdong.
The typhoon brought 18 inches of rain to the Philippine area. Like Florence, its destructive force is related to the amount of water it brings about in the form of rainstorms rather than its wind speed.
The cyclones’ rainfall is directly related to the additional energy transmitted to the atmosphere by global warming. Warmer oceans evaporate more, which in turn produces rainfall, ocean surges and stronger floods — precisely some of the more extreme events predicted by climate change simulations.
Still, the American president, Donald Trump, continues to dismantle carbon emissions reduction policies. History’s most polluting country withdrew from the 2015 Paris climate agreement which was arduously negotiated and clearly not enough to contain global warming at safe levels.
However, it is not all bad news. Last week, hundreds of governors, mayors and aboriginal leaders attended the Global Climate Action Summit in San Francisco, striving to follow a different direction than Trump — and not just in speeches.
One hundred big companies in the food and fiber industry revealed billions of dollars in investments in smart agriculture to reduce climate pollution. Nine foundations intend to donate approximately $7.6 billion until 2022 to encourage traditional people to preserve forests.
A group of 27 cities with a total of 54 million inhabitants announced that they have reduced their carbon emissions over a period of five years (but none of the cities are in developing countries).
As evidence is gathered, decision-makers are leaving ideology aside and taking a pragmatic approach to climate change. Let’s hope it is not too little, too late.
Distanciando-se de Trump, lÃderes adotam postura pragmática diante da mudança do clima
Do outro lado do globo, o tufão Mangkhut castigou as Filipinas com dezenas de vÃtimas, a maioria delas composta por mineiros soterrados em deslizamento de terra (muitos deles ainda desaparecidos). Depois, provocou caos em Hong Kong e na provÃncia chinesa de Guangdong.
Mangkhut levou 450 mm de precipitação a localidades filipinas. Como o Florence, sua força destruidora se relaciona mais com a quantidade de água que mobiliza na forma de chuva do que com ventos.
A pluviosidade dos ciclones está em relação direta com a energia adicional aportada à atmosfera pelo aquecimento global. Oceanos mais quentes ensejam mais evaporação, o que produz chuvas, ressacas e inundações mais fortes —precisamente alguns dos eventos extremos previstos nos modelos que simulam a mudança climática.
Ainda assim, o presidente americano, Donald Trump, prossegue no desmantelamento de polÃticas de redução de emissões de carbono. O paÃs que mais poluiu na história se retirou do Acordo de Paris (2015), negociado a duras penas e claramente insuficiente para conter o aquecimento em nÃvel seguro.
Um grupo de 27 metrópoles, totalizando 54 milhões de habitantes, anunciou já ter reduzido suas emissões de carbono num perÃodo de cinco anos (mas nenhuma delas nos paÃses em desenvolvimento).
Conforme as evidências se acumulam, vê-se, tomadores de decisão deixam as ideologias à parte e adotam uma postura pragmática diante da mudança do clima. Oxalá não seja pouco e tarde demais.

Washington is no longer content with slow exhaustion; it has adopted a strategy of swift, symbolic strikes designed to recalibrate the international landscape.
President Donald Trump is calling on people to distrust environmental measures and ... the scientific community. He will have to prove there are no floods caused by unrelenting rain ...and that the wildfires in his country have not been caused by ... climate change.
[T]he president failed to disclose that subsidies granted by his government — in connivance with the Republican Party — artificially maintain the viability of fossil fuels.
